AMENDED REASONS FOR JUDGMENT
[These amended reasons for judgment are issued in substitution

to correct a grammatical error in footnote 19.]
Jorré J.
Introduction
[1] The Appellant’s youngest child, “X”, has classical phenylketonuria (“PKU”). PKU is a genetic disorder that eliminates or severely restricts the body’s ability to metabolize phenylalanine (“Phe”), an amino acid necessary for healthy growth and development. Phe is found in all natural dietary proteins. [1] PKU has very severe consequences unless the necessary treatment plan is followed vigorously and unrelentingly. Untreated it would cause permanent severe damage to the brain of the child.
[2] The following describes clearly and succinctly both the nature of PKU and its potential consequences: [2]
. . . [Classical] Phenylketonuria is an inherited impairment of the body’s ability to metabolize the amino acid phenylalanine. This is a genetic condition, meaning it is life long and starts at birth. This is a serious condition, as phenylalanine metabolism is a vital function. Without the ability to metabolize phenylalanine, the levels of phenylalanine in the body quickly rise (within a day) to toxic levels. Short term, high phenylalanine affects cognitive ability (executive function) and long term (in children) causes permanent severe brain damage.
People who do not have this impairment (i.e. do not have phenylketonuria) can metabolize phenylalanine, therefore they do not have to follow a phenylalanine-restricted diet. People with phenylketonuria must follow the treatment plan and have blood phenylalanine levels monitored for their entire lives. If they consume a regular diet they will be causing brain damage to themselves. [X’s] formula prescription is: 110 grams Phenex-2 powder mixed with 560 mL water per day (divided 140 mL QID) and 300 mg (20 exchanges) phenylalanine per day from all dietary sources including food and metabolic products supplied by the Ontario Public Drug Program’s Inherited Metabolic Diseases Program. . . .
[Emphasis added.]
[3] As we will see below the therapy consists of strictly regulating the amount of Phe consumed. Every day the aim is to consume a very specific amount of Phe. If too little is consumed there will not be normal growth and development; if too much is consumed there will be brain damage. Metaphorically, the Appellant and her child are obliged to walk a very narrow ridge with great risks if the child falls to either side. [3]
[4] The narrowness of the “ridge” is well illustrated by the fact that a single egg will contain Phe in excess of the child’s daily allowance.
[5] In 2015 the Appellant applied for the credit for mental or physical impairment, commonly known as the disability tax credit (“DTC”), in respect of X. The Minister of National Revenue (“Minister”) determined that X did not fulfill the requirements and the Appellant now appeals from that determination. [4]
[6] The only issue here is whether X is eligible for the credit. Much is not in dispute; I note, for example, that there is no issue of computation and no issue as to the fact that, if X is eligible, the credit may be transferred to the Appellant.
[7] As we shall see below, the dispute ultimately turns on what I shall refer to as “the 14‑hour a week requirement”.
The Statutory Scheme [5]
[8] The relevant provisions are in sections 118.3 and 118.4 of the Income Tax Act (“Act”); they are reproduced in annex A of these reasons. Because the only issue is eligibility, and given the particular facts, only portions of those two sections are relevant and I will only reproduce part of those sections below:
118.3(1) Credit for mental or physical impairment — Where
(a) an individual has one or more severe and prolonged impairments in physical or mental functions,
(a.1) the effects of the impairment or impairments are such that the individual’s ability to perform more than one basic activity of daily living is significantly restricted where the cumulative effect of those restrictions is equivalent to having a marked restriction in the ability to perform a basic activity of daily living or are such that the individual’s ability to perform a basic activity of daily living is markedly restricted or would be markedly restricted but for therapy that
(i) is essential to sustain a vital function of the individual,
(ii) is required to be administered at least three times each week for a total duration averaging not less than 14 hours a week, and
(iii) cannot reasonably be expected to be of significant benefit to persons who are not so impaired,
(a.2) in the case of an impairment in physical or mental functions the effects of which are such that the individual’s ability to perform a single basic activity of daily living is markedly restricted or would be so restricted but for therapy referred to in paragraph (a.1), a medical practitioner has certified in prescribed form that the impairment is a severe and prolonged impairment in physical or mental functions the effects of which are such that the individual’s ability to perform a basic activity of daily living is markedly restricted or would be markedly restricted, but for therapy referred to in paragraph (a.1), where the medical practitioner is a medical doctor or, in the case of
. . .
(a.3) in the case of one or more impairments in physical or mental functions the effects of which are such that the individual’s ability to perform more than one basic activity of daily living is significantly restricted, a medical practitioner has certified in prescribed form that the impairment or impairments are severe and prolonged impairments in physical or mental functions the effects of which are such that the individual’s ability to perform more than one basic activity of daily living is significantly restricted and that the cumulative effect of those restrictions is equivalent to having a marked restriction in the ability to perform a single basic activity of daily living, where the medical practitioner is, in the case of
(i) an impairment with respect to the individual’s ability in feeding or dressing themself, or in walking, a medical doctor or an occupational therapist, and
(ii) in the case of any other impairment, a medical doctor,
(b) the individual has filed for a taxation year with the Minister the certificate described in paragraph (a.2) or (a.3), and
(c) . . .
there may be deducted in computing the individual’s tax payable under this Part for the year the amount determined by the formula
. . .
(1.1) Time spent on therapy — For the purpose of paragraph 118.3(1)(a.1), in determining whether therapy is required to be administered at least three times each week for a total duration averaging not less than an average of 14 hours a week, the time spent on administering therapy
(a) includes only time spent on activities that require the individual to take time away from normal everyday activities in order to receive the therapy;
(b) in the case of therapy that requires a regular dosage of medication that is required to be adjusted on a daily basis, includes (subject to paragraph (d)) time spent on activities that are directly related to the determination of the dosage of the medication;
(c) in the case of a child who is unable to perform the activities related to the administration of the therapy as a result of the child’s age, includes the time, if any, spent by the child’s primary caregivers performing or supervising those activities for the child; and
(d) does not include time spent on activities related to dietary or exercise restrictions or regimes (even if these restrictions or regimes are a factor in determining the daily dosage of medication), travel time, medical appointments, shopping for medication or recuperation after therapy.
(2) Dependant having impairment — . . .
(3) Partial dependency — . . .
(4) Additional information — . . .
118.4(1) Nature of impairment — For the purposes of subsection 6(16), sections 118.2 and 118.3 and this subsection,
(a) an impairment is prolonged where it has lasted, or can reasonably be expected to last, for a continuous period of at least 12 months;
(b) an individual’s ability to perform a basic activity of daily living is markedly restricted only where all or substantially all of the time, even with therapy and the use of appropriate devices and medication, the individual is blind or is unable (or requires an inordinate amount of time) to perform a basic activity of daily living;
(b.1) an individual is considered to have the equivalent of a marked restriction in a basic activity of daily living only where all or substantially all of the time, even with therapy and the use of appropriate devices and medication, the individual’s ability to perform more than one basic activity of daily living (including for this purpose, the ability to see) is significantly restricted, and the cumulative effect of those restrictions is tantamount to the individual’s ability to perform a basic activity of daily living being markedly restricted;
(c) a basic activity of daily living in relation to an individual means
(i) mental functions necessary for everyday life,
(ii) feeding oneself or dressing oneself,
(iii) speaking so as to be understood, in a quiet setting, by another person familiar with the individual,
(iv) hearing so as to understand, in a quiet setting, another person familiar with the individual,
(v) eliminating (bowel or bladder functions), or
(vi) walking;
(c.1) mental functions necessary for everyday life include
(i) memory,
(ii) problem solving, goal-setting and judgement (taken together), and
(iii) adaptive functioning;
(d) for greater certainty, no other activity, including working, housekeeping or a social or recreational activity, shall be considered as a basic activity of daily living;
(e) feeding oneself does not include
(i) any of the activities of identifying, finding, shopping for or otherwise procuring food, or
(ii) the activity of preparing food to the extent that the time associated with the activity would not have been necessary in the absence of a dietary restriction or regime; and
(f) dressing oneself does not include any of the activities of identifying, finding, shopping for or otherwise procuring clothing.
(2) Reference to medical practitioners, etc. — . . .
[9] It will be useful to note at this point that the Canadian Oxford Dictionary (second edition, 2004) defines “therapy” as:
1 The treatment of physical or mental disorders, other than by surgery; 2 a particular type of such treatment.
[10] The same dictionary gives three definitions of the noun “diet”:
1 The kinds of food that a person or animal habitually eats; 2 a special course of food to which a person is restricted, esp. for medical reasons or to control weight; 3 a regular occupation or series of activities to which one is restricted or which form one’s main concern, usually for a purpose (a diet of light reading and fresh air).
In this context the second meaning would be the relevant one.
The Issues
[11] Under these provisions, the Act has a number of requirements that must be met before an individual is eligible for the disability tax credit; for our purposes here, these include: [6]
1. The individual must have one or more severe and prolonged impairments.
2. The effects of impairment(s) must be such that the individual is either
(a) markedly restricted in his or her ability to perform a basic activity of daily living, or
(b) significantly restricted in the ability to perform more than one basic activity of daily living with the consequence that the cumulative effect of the restrictions is equivalent to being markedly restricted in the ability to perform a basic activity of daily living, or
(c) would be restricted as described in (a) but for therapy meeting certain requirements. [7]
3. A certificate by a medical practitioner must be filed.
[12] The Respondent does not dispute that many of the requirements are met; its position is the following:
1. It accepts that X suffers from one or more severe and prolonged impairments with the effect that
2. X would be markedly restricted in her ability to perform a basic activity of daily living but for the therapy received. [8]
3. However, the Respondent contends that the therapy received does not meet the requirements of the Act.
[13] The sole issue [9] in this case is whether or not the therapy meets the requirements of the Act.
[14] Paragraph 118.3(1)(a.1) of the Act requires that the individual:
. . . would be markedly restricted but for therapy that
(i) is essential to sustain a vital function of the individual,
(ii) is required to be administered at least three times each week for a total duration averaging not less than 14 hours a week, and
(iii) cannot reasonably be expected to be of significant benefit to persons who are not so impaired,
[15] More specifically the Respondent’s argument was limited to (ii) above and to the 14‑hour a week requirement; [10] it is very clear that there is therapy more than three times and that aspect of (ii) is not disputed. The Respondent did not take the position that the requirements of (i) and (iii) were not met.
[16] Accordingly the issue is whether or not therapy was administered for an average of not less than 14 hours a week.
[17] In computing the 14‑hour a week requirement, the rules in subsection 118.3(1.1) are important and provide that:
. . . the time spent on administering therapy
(a) includes only time spent on activities that require the individual to take time away from normal everyday activities in order to receive the therapy;
(b) in the case of therapy that requires a regular dosage of medication that is required to be adjusted on a daily basis, includes (subject to paragraph (d)) time spent on activities that are directly related to the determination of the dosage of the medication;
(c) in the case of a child who is unable to perform the activities related to the administration of the therapy as a result of the child’s age, includes the time, if any, spent by the child’s primary caregivers performing or supervising those activities for the child; and
(d) does not include time spent on activities related to dietary or exercise restrictions or regimes (even if these restrictions or regimes are a factor in determining the daily dosage of medication), travel time, medical appointments, shopping for medication or recuperation after therapy.
[18] The French language version of this text reads as follows:
[…] le temps consacré à donner les soins est calculé selon les critères suivants :
a) n’est compté que le temps consacré aux activités qui obligent le particulier à interrompre ses activités courantes habituelles pour recevoir les soins;
b) s’il s’agit de soins dans le cadre desquels il est nécessaire de déterminer un dosage régulier de médicaments qui doit être ajusté quotidiennement, est compté, sous réserve de l’alinéa d), le temps consacré aux activités entourant directement la détermination de ce dosage;
c) dans le cas d’un enfant qui n’est pas en mesure d’accomplir les activités liées aux soins en raison de son âge, est compté le temps que consacrent les principaux fournisseurs de soins de l’enfant à accomplir ces activités pour l’enfant ou à les surveiller;
d) n’est pas compté le temps consacré aux activités liées au respect d’un régime ou de restrictions alimentaires ou d’un programme d’exercices (même si ce régime, ces restrictions ou ce programme sont pris en compte dans la détermination du dosage quotidien de médicaments), aux déplacements, aux rendez-vous médicaux, à l’achat de médicaments ou à la récupération après les soins.
The Facts
[19] X was born in 2013 and was diagnosed with PKU shortly thereafter, through a newborn screening process. The Appellant is X’s primary caregiver.
[20] Dr. Murray Potter, X’s metabolic specialist, completed and certified a prescribed form (the T2201 — Disability Tax Credit Certificate) for the Appellant to apply for the DTC in respect of X. [11]
[21] Dr. Potter provided two letters supporting the Appellant’s DTC claim. The first letter, dated April 12, 2016, was in support of the Appellant’s objection to the Minister’s determination denying the DTC application. The letter explained the cause, effects and treatment of PKU as follows. [12] It is worth reproducing large portions of the letter:
. . .
Phenylketonuria, or PKU, is an inherited enzyme deficiency. The deficient enzyme, phenylalanine hydroxylase, is necessary to metabolize the amino acid phenylalanine [“Phe”]. Phenylalanine is a component of all of our dietary protein, and without the enzyme the level of phenylalanine quickly builds up in the body to toxic levels. Over a relatively short period of time (weeks to month) high levels of phenylalanine causes irreversible brain damage. Conceptually, the treatment for PKU is simple — reduce the intake of phenylalanine to a very low level, just enough to provide the body a supply for making new proteins for growth and development, but not enough to cause a build-up to a toxic level. In practice, this is a very difficult goal.
The first challenge is that the degree of protein restriction that would be necessary to give safe levels of phenylalanine in the body is not compatible with life. Therefore, artificial nutrition has been created (called “medical food” or “PKU formula”) where the level of phenylalanine is zero, but other amino acids and nutrients are supplemented to safe levels. This medical food is only available through special access at a few centres in Canada, and must be given under a medical prescription with close supervision by the metabolic physician and registered dietitian. Even with the medical food supplying a large portion of the nutrition, additional special “low protein” foods must be consumed to provide a complete diet. An example of a low protein food would be a pasta or bread product where the high protein component (flour) has been replaced with a low protein substitute (starch), often at a considerable sacrifice in palatability. Most of these foods are also special order through the same centres supplying the medical food, though they typically do not require a prescription to purchase.
The second challenge is that, as mentioned above, a certain amount of phenylalanine is necessary for proper growth and development, but too much is toxic. The phenylalanine intake is carefully regulated by providing some regular food protein (which contains phenylalanine). Essentially [X] is prescribed a certain specific amount of phenylalanine to consume every day, to be given as food protein. This amount must be calculated for every food item that is consumed for every meal, every day. The prescribed amount of phenylalanine changes based on stages of growth and development and must be carefully monitored by frequent blood level checks for phenylalanine (weekly as a young child gradually increasing to every 1-3 months as an adult, when growth stops). These blood checks are only available at specialized laboratories (i.e. tertiary care hospital laboratories with biochemical genetics laboratories).
[X]’s parents must care for [X] by:
• Monitoring blood phenylalanine levels (doing blood tests), with the goal to maintain blood levels in the range of 120 to 360 umol/l
• Daily preparing and administering formula and low protein foods (PKU medication)
• Maintaining a logbook of blood phenylalanine levels and daily phenylalanine intake
The specific time requirements necessary to manage the phenylalanine prescription would vary from family to family and I would have no way to know exactly how long any one patient spends on this. However, this is a daily task that could easily require 2 hours per day (14 hours per week). Additionally, there is a significant amount of time dedicated to obtaining and tracking the blood phenylalanine levels. Therefore, it is reasonable to say that managing PKU meets the “at least 3 times per week, for an average of at least 14 hours per week” requirement. Managing PKU is a very time consuming regime and would consist of a child and parent/caregiver taking time away from everyday activities. This is a life‑long, inherited condition, requiring life-long treatment.
Implementing a phenylalanine restricted diet early in life can significantly reduce mental deficiencies associated with PKU. Left untreated, PKU causes severe brain damage leading to severe cognitive impairment and the inability to perform any of the mental functions required for everyday life. [X] was treated within the early weeks of life with good metabolic control, protecting her brain and allowing for completely normal development. She will need to remain on therapy to avoid any adverse neuropsychiatric effects of PKU.
[Emphasis added.]
[22] As indicated above, treatment for PKU is not simply eliminating or reducing Phe from one’s diet. It is maintaining the amount of Phe intake at a very specific level, no more and no less, so that the patient has just enough Phe for proper growth and development but not more so as to prevent brain damage. The Appellant stated that her daily Phe consumption was approximately 4,300 milligrams. In contrast, X’s prescribed daily Phe consumption target was 300 milligrams. This target could be exceeded very quickly if X’s diet was not closely controlled and monitored by the Appellant. The Appellant testified that one large egg and a cup of milk contain 341 milligrams and 358 milligrams of Phe, respectively.
[23] Dr. Potter’s second letter, dated February 17, 2017, was in support of the Appellant’s appeal to this Court. Most of it has already been reproduced in paragraph 2 above.
[24] The therapy consists of managing the daily amount of Phe consumed very precisely while also ensuring a sufficient intake of all the other amino acids, apart from Phe, that constitute the necessary protein intake for the child. This is accomplished by a carefully managed combination of three components:
1. The prescribed formula (the medical formula) that Dr. Potter described as artificial nutrition — The formula provides a complete set of proteins except for Phe [13] and must be taken four times a day in the morning, at lunch time, in the afternoon and at bedtime. The formula consists of a prescribed amount of amino acid powder dissolved in a particular amount of water.
2. Special processed low protein foods (the medical foods) — For example, there are pasta products where the high protein component (such as flour) has been replaced with a low protein substitute (such as starch); unfortunately, the result is less palatable than normal pasta. These medical foods are quite expensive.
3. Limited quantities of ordinary foods that have little or no Phe as well as completely avoiding many foods that have high Phe.
[25] Many foods must be completely avoided; in a letter to the school board prior to the child starting junior kindergarten, her parents write: [14]
[X] is not allowed to eat meat, seafood, poultry, eggs, dairy, soy, nuts, beans, seeds, lentils, or many products containing regular flour. She is also not allowed to have aspartame. All of the above food items contain too much PHE.
[26] The prescribed amount of Phe evolves over time.
[27] As indicated in Dr. Potter’s letter, the medical foods are specially prepared so as to reduce the protein content. These medical foods are not generally available. They cannot be bought in grocery stores and have to be ordered and shipped to the customer. Apparently, there is a specialty food store within the Hospital for Sick Children in Toronto.
[28] The medical foods come in packages with warnings such as “For use under medical supervision for conditions such as inborn errors of protein metabolism” or “Important notice — Should be used under medical supervision. For the dietary management of Inherited Metabolic Disorders requiring low protein diets. Not suitable for the sole nourishment of the person.” Some packages say “Low Protein Medical Food.” [15]
[29] The Appellant applied to the Ontario Ministry of Health and Long‑Term Care Inherited Metabolic Diseases Program to obtain the benefits of that program for X. To apply, Dr. Potter also had to provide a diagnosis and sign the form. [16] The program apparently covers the cost of certain medical foods. [17]
[30] Generally X’s therapy takes away a limited amount of time from what the child would otherwise be doing because, given her age, she is unable to manage her own therapy. However, the Appellant, as X’s primary caregiver, is obliged to implement the therapy; this implementation is time consuming and includes the following:
– sourcing and storing medical formula and medical food;
– planning and preparing X’s meals and snacks including:
• weighing food so as to measure, calculate, and log the amount of Phe from all sources prepared for X’s consumption so as to ensure the correct amount of daily Phe consumption as well as
• measuring and logging the formula to ensure adequate consumption of all the other amino acids (apart from Phe) constituting protein;
– supervising X’s consumption of food so the amount of Phe actually consumed is monitored;
– if necessary, after a meal or snack, recalculating Phe consumption for the rest of the day and adjusting subsequent meals or snacks to take account of actual consumption (for example, if a food is not eaten or only partly eaten with the result that less food than planned was consumed, then it will be necessary to ensure more Phe is consumed by adding or substituting something; another example, where adjustments have to be made, is this: if, for instance, in spite of efforts to avoid this, X winds up eating some other child’s food it may be necessary to try to make an offsetting reduction in Phe consumption for the day);
– educating others, such as caregivers, teachers, classmates and other parents, regarding PKU so as to prevent consumption of more Phe than planned (for example, ice cream at a friend’s home);
– when picking up X from the care of others, finding out what medical formula and medical food and ordinary food was consumed — normally the Appellant will pick up any leftover meal or snack items so that they can be measured (weighed) and the amount of Phe consumed up to that point in the day can be recalculated for the purpose of making adjustments for the rest of the day;
– attending various medical appointments with different doctors and the dietitian;
– monitoring X’s Phe blood level through weekly blood tests to ensure that the prescribed Phe‑restricted diet is effective.
[31] In annex B, I have reproduced the full list of tasks contained in the time sheet the Appellant filed setting out her estimate of the time she spent to implement her child’s therapy. She estimated that in an average week she spent about 29 hours.
[32] The Appellant filed a letter sent to the school board prior to X starting junior kindergarten. [18] Because it gives a good sense of the challenges involved in X attending kindergarten, I am reproducing the letter:
We are excited about registering [X] for Junior Kindergarten for September 2017 and she is as well! Her big brother . . ., currently in JK2, has been preparing her well for “Big Kid School”. Like her brother, [X] also has PKU (Phenylketonuria). As indicated below, my hope is that [X] will be placed in JK2 with her brother, so that she can also have access to the refrigerator in the room for her medical formula.
What is PKU?
PKU is a rare, inherited metabolic disease that results in developmental disability and other neurological problems when treatment is not started within the first few weeks of life. We started treatment as soon as [X] was diagnosed (4 days after she was born) and, as a result, she is developing into a wonderfully healthy little girl. Individuals with PKU are unable to break down one amino acid of protein called phenylalanine (often called PHE, pronounced “fee”). Since this amino acid cannot be completely processed, it builds up in their blood and excess amounts cross the blood-brain barrier. When excess amounts build up, brain damage and other neurological problems result.
How is [X]’s PKU managed?
Thankfully, PKU can be managed with a very strict diet. [X]’s PKU management involves:
1) Controlling her intake of protein
a. [X] is not allowed to eat meat, seafood, poultry, eggs, dairy, soy, nuts, beans, seeds, lentils, or many products containing regular flour. She is also not allowed to have aspartame. All of the above food items contain too much PHE. Even fruits and vegetables are carefully weighed and accounted for so that the daily PHE intake is within her target each day — not over, or there is risk of brain damage, and not under, or there is risk of retarded growth. Everything [X] eats must be accounted for. Similarly, everything she doesn’t eat must be subtracted from her intake for the day.
2) Drinking a PHE-free formula
a. [X]’s medical formula provides her body with most of the necessary protein, vitamins, and minerals that she needs, without the PHE, to help her grow like her peers.
3) Eating special low-PHE foods
a. These foods are considered “medical foods” and are specially ordered (i.e., they are not available at the grocery store).
4) Weekly to bi-weekly blood work
a. [X] is monitored by a team at McMaster Children’s Hospital. She must give blood bi-weekly to ensure that her blood PHE levels are within a specific range. When her levels are too high, we attend weekly so that her clinical team can adjust her diet and formula requirements accordingly.
To give you an idea of how significantly [X]’s diet is restricted, [X] is currently allowed to eat 300 mg of PHE per day (~6.5 g of protein) from the foods we have to weigh and account for. One large egg has 341 mg of PHE. One cup (250 ml) of milk has 358 mg of PHE. Thus, as you can see, [X] cannot have any of the above examples of foods as each of them individually would put her over, or just about over, her daily intake for that day, meaning that she wouldn’t be able to consume anything else without increasing her blood-PHE levels and ultimately causing damage to her brain.
Currently, in preschool, [X] does not eat what is provided by the centre like her peers. Her food is prepared and weighed at home and her teachers give it to her during snack and lunch times. The centre shared their menu with me so that I can provide similar options as often as possible (e.g., low protein spaghetti, low protein banana bread, etc.). [X]’s teaching staff knows that any food that is uneaten must be returned home for weighing and there is a notice (similar to a severe allergy notice) in the room that she is not to eat her peers’ food and is not to consume foods with protein. Any time a special treat is being offered by the school, they either contact me to ask if she is allowed to eat it, as there are some foods that we all eat that she can also have (e,g., apples, applesauce, certain popsicles/freezies and candies), or they give me notice so that I can provide a low protein alternative (e.g., low protein cupcakes) so that she does not feel left out.
What does this mean for the school?
Given the many allergies and food restrictions for children these days, my hope is that this will not be too much of a change for the school. Just like the rest of your students, I will of course provide her lunch/snacks every day. What will be different for her is that she needs to bring whatever she does not eat home, rather than throwing it in the garbage or green bin. Also, and probably my main concern, is that she cannot share food with her friends. If she gives her food to her friends she will be hungry, and if she eats her friends’ food, it may have protein in it. Furthermore, given that she consumes her medical formula across the day, in addition to a bottle for water like her peers, she will also need to bring a thermos/water bottle of her formula to school. My hope is that she will be assigned to JK2 with her brother, so that she too can put her formula in the fridge. Finally, to accommodate her bi-weekly blood work appointments at McMaster Children’s Hospital, [X] will unfortunately be a little late (~9:30 to 10:00) every other Tuesday morning. I will notify the school if weekly appointments will leave [X] being late more often.
What happens if she eats too much protein?
It is important to note that [X] is NOT allergic to protein. If she eats something that she shouldn’t, she will not have an allergic reaction and should not require medical attention. Instead, what you might see is a change in her behaviour. Excess protein in the short term typically presents with irritability, high activity level, fidgeting, poor attention, etc. Excess protein over a longer period of time (even as short as a week) is what leads to more significant brain damage (e.g., seizures, intellectual decline). Accidents can happen. What will be incredibly important will be for staff to notify myself or my husband if [X] eats something that she shouldn’t. If this happens, we will alter [X]’s diet accordingly (i.e., provide her with an even lower protein dinner that day, lower her protein intake over the following days, etc.). I can only do this if I know about it though.
If you have any further questions, please do not hesitate to contact me.
Analysis [19]
[33] In Johnston v. Canada, [20] the Federal Court of Appeal adopted the following comments made by former Chief Justice Bowman of this Court with respect to the disability tax credit: [21]
. . .
The legislative intent appears to be to provide a modest relief to persons who fall within a relatively restricted category of markedly physically or mentally impaired persons. The intent is neither to give the credit to everyone who suffers from a disability nor to erect a hurdle that is impossible for virtually every disabled person to surmount. It obviously recognizes that disabled persons need such tax relief and it is intended to be of benefit to such persons.
. . .
If the object of Parliament, which is to give to disabled persons a measure of relief that will to some degree alleviate the increased difficulties under which their impairment forces them to live, is to be achieved the provisions must be given a humane and compassionate construction.
[34] As we saw above, the word “therapy” simply means the treatment. Given that the treatment is administering a precise amount of Phe every day, the activities described in paragraph 30 above, and also set out in annex B, all constitute administration of the treatment or therapy. One must carry out these activities in order to deliver the Phe, measure the outcome (through the weekly blood tests) and, over time, make adjustments.
[35] However, in determining whether the therapy is administered at least three times a week for no less than an average of 14 hours a week, I must apply the rules set out in subsection 118.3(1.1); these rules modify the ordinary meaning of administering the therapy. For convenience, I will repeat them here:
. . . the time spent on administering therapy
(a) includes only time spent on activities that require the individual to take time away from normal everyday activities in order to receive the therapy;
(b) in the case of therapy that requires a regular dosage of medication that is required to be adjusted on a daily basis, includes (subject to paragraph (d)) time spent on activities that are directly related to the determination of the dosage of the medication;
(c) in the case of a child who is unable to perform the activities related to the administration of the therapy as a result of the child’s age, includes the time, if any, spent by the child’s primary caregivers performing or supervising those activities for the child; and
(d) does not include time spent on activities related to dietary or exercise restrictions or regimes (even if these restrictions or regimes are a factor in determining the daily dosage of medication), travel time, medical appointments, shopping for medication or recuperation after therapy.
[36] These rules exclude the time spent on certain activities while including certain other time. I would note that:
1. Paragraph 118.3(1.1)(a) excludes any time spent that does not prevent the patient from carrying out normal everyday activities. As a result the child spends little time that would be counted. For example, while X is eating she is receiving a limited amount of Phe but since eating is a normal everyday activity no time is taken away from everyday activities. On the other hand having a blood test is not an everyday activity and the time X spends getting a blood test every week does count.
2. Paragraph (c) explicitly provides that time spent by the Appellant’s primary caregivers administering or supervising the administration of the treatment does count.
3. Paragraph 118.3(1.1)(b) and the words in brackets in paragraph (d) do not appear to have application here because, as I understand the therapy, there is a fixed daily Phe dosage. If something goes wrong during the day, there will have to be adjustments to try to get back to the dosage but the prescribed dose of Phe itself does not change; it may change as the child grows and as a result of the analysis of the blood tests but it is not a daily adjustment of dosage.
4. Paragraph (d) excludes from the 14‑hour average any time spent on:
– dietary restrictions or regimes,
– travel time,
– medical appointments and
– shopping for medication.
[37] In my view, medical appointments in paragraph 118.3(1.1)(d) include meetings with doctors and other health professionals but do not include a medical appointment where there is more than a meeting or discussions with the professional. For example, it would not include an appointment where there is actual treatment or testing that is part of the treatment. [22]
[38] Here, the Appellant has included in her time sheet a certain amount of time that relates to medical appointments, travel and buying medication. Those times cannot be included in the 14‑hour average but represent a small part of the total time she estimates that she spends.
[39] The question then becomes: In these particular circumstances what exactly does paragraph 118.3(1.1)(d) exclude from the 14‑hour a week average when it refers to dietary restrictions or regimes?
[40] In order to apply subsection 118.3(1.1) one must consider how to treat the three components of the therapy and the different activities related to the three components in this situation, a situation that would probably not have been contemplated by the government or Parliament at the time subsection (1.1) was enacted.
[41] The weekly blood test and the administration of the prescription medical formula are straightforward. The blood tests are essential to the therapy
