1.
Malik is charged with assault causing bodily harm. At trial, the Crown proves Malik intentionally struck the victim but argues no further mental element is required beyond the intent to apply force. The defence argues the Crown must also prove Malik subjectively foresaw that bodily harm would result. Which of the following best states the correct mens rea standard for assault causing bodily harm under Canadian law?
2.
During a drug investigation, police lawfully arrest Nina and search her home incident to arrest without a warrant, seizing cocaine. At trial, Nina argues the search violated s. 8 of the Charter and the evidence should be excluded under s. 24(2). The trial judge admits the evidence. On appeal, which framework governs the s. 24(2) analysis?
3.
Priya is charged with theft. Her trial commences 36 months after her charges are laid; roughly 8 months of the delay is attributable to defence-requested adjournments. The defence brings an application for a stay of proceedings under s. 11(b) of the Charter. Applying the current framework, what is the presumptive ceiling for superior court proceedings, and how are defence-caused delays treated?
4.
The Crown charges Delmar, a restaurant owner, with a regulatory offence of selling food that did not meet provincial health standards. Delmar argues he had no knowledge of the contamination and took all reasonable precautions. The offence provision is silent on mens rea. What category of liability most likely applies, and what must Delmar prove to avoid conviction?
5.
Tamara is convicted of robbery and the sentencing judge imposes a sentence 20% above the range established in appellate guidelines, citing the need for general deterrence in the community. Tamara appeals, arguing the sentence is unreasonable. Under Canadian sentencing law, what is the correct standard of appellate review for a sentence?
6.
During a confrontation, Omar is attacked by an assailant wielding a knife. Omar grabs a nearby bottle and strikes the assailant, fracturing his skull. The assailant dies. Omar is charged with manslaughter and raises self-defence. The trial judge instructs the jury that self-defence is only available if the force used was 'exactly proportionate' to the threat. Is this instruction correct under Canadian law?
7.
Brigitte is charged with break and enter. The Crown discloses most of its file but withholds a police informant's identity, claiming the information is protected by informer privilege. Brigitte argues she needs the informant's identity to make full answer and defence. The trial judge refuses disclosure. Is the trial judge correct?
8.
Lee is found in possession of a prohibited firearm in a province where mandatory minimum sentences apply. The trial judge finds the mandatory minimum of three years grossly disproportionate as applied to Lee's particular circumstances. The judge imposes a conditional sentence instead. The Crown appeals.

Questions & answers

1. Malik is charged with assault causing bodily harm. At trial, the Crown proves Malik intentionally struck the victim but argues no further mental element is required beyond the intent to apply force. The defence argues the Crown must also prove Malik subjectively foresaw that bodily harm would result. Which of the following best states the correct mens rea standard for assault causing bodily harm under Canadian law?
Answer: The Crown need only prove Malik intentionally applied force; objective foreseeability of bodily harm satisfies the fault element.
For assault causing bodily harm under s. 267 of the Criminal Code, the mens rea is the general intent to apply force (the assault); the 'causing bodily harm' element is assessed on an objective foreseeability standard, not subjective foresight. This is consistent with the Supreme Court's approach in R v Sault Ste Marie (City of) [1978] 2 SCR 1299, which established the taxonomy of true crimes versus strict/absolute liability, and the broader principle that Parliament may constitutionally impose objective fault for non-stigma offences that do not engage the 'minimum' subjective fault requirement under s. 7. Option A overstates the mens rea; options C and D are incorrect as to the fault standard; option E conflates civil negligence with criminal recklessness.
2. During a drug investigation, police lawfully arrest Nina and search her home incident to arrest without a warrant, seizing cocaine. At trial, Nina argues the search violated s. 8 of the Charter and the evidence should be excluded under s. 24(2). The trial judge admits the evidence. On appeal, which framework governs the s. 24(2) analysis?
Answer: The court balances three Grant factors: seriousness of the Charter-infringing conduct, impact on the accused's Charter-protected interests, and society's interest in adjudication on the merits.
R v Grant (2009) SCC 32 established the current three-part s. 24(2) framework: (1) seriousness of the state conduct, (2) impact on the accused's Charter-protected interests, and (3) society's interest in a trial on the merits. Automatic exclusion (A) was expressly rejected in Grant. Option C describes the pre-Grant Collins test, which Grant replaced. Option D is wrong because a search incident to arrest still must satisfy s. 8 reasonableness. Option E describes inevitable discovery, a doctrine relevant to admissibility under certain U.S. rules, not the Canadian s. 24(2) framework.
3. Priya is charged with theft. Her trial commences 36 months after her charges are laid; roughly 8 months of the delay is attributable to defence-requested adjournments. The defence brings an application for a stay of proceedings under s. 11(b) of the Charter. Applying the current framework, what is the presumptive ceiling for superior court proceedings, and how are defence-caused delays treated?
Answer: The presumptive ceiling is 30 months for superior court proceedings; defence-caused delays are subtracted from the total delay before comparing to the ceiling.
R v Jordan (2016) SCC 27 set the presumptive ceiling at 18 months for provincial court and 30 months for superior court proceedings (from charge to end of trial). Delays solely attributable to the defence are subtracted from the total delay before comparing to the ceiling. Option E states incorrect ceilings. Option B gives wrong ceilings and wrongly dismisses defence delays. Option C describes the pre-Jordan Morin framework. Option D correctly identifies the 30-month ceiling but incorrectly states how defence delays are treated.
4. The Crown charges Delmar, a restaurant owner, with a regulatory offence of selling food that did not meet provincial health standards. Delmar argues he had no knowledge of the contamination and took all reasonable precautions. The offence provision is silent on mens rea. What category of liability most likely applies, and what must Delmar prove to avoid conviction?
Answer: Strict liability: the Crown proves the actus reus, after which Delmar may avoid conviction by proving on a balance of probabilities that he took all reasonable care.
R v Sault Ste Marie (City of) [1978] 2 SCR 1299 created the three-category framework for regulatory offences: (1) true crimes requiring mens rea, (2) strict liability where the Crown proves the act and the accused may raise due diligence on a balance of probabilities, and (3) absolute liability. Regulatory offences silent on mens rea presumptively fall into the strict liability category. Option B incorrectly classifies the offence as absolute liability. Option A requires Crown to prove subjective fault, which is wrong for this regulatory offence. Option D misstates the burden-shifting rule. Option E conflates directing mind doctrine with absolute liability.
5. Tamara is convicted of robbery and the sentencing judge imposes a sentence 20% above the range established in appellate guidelines, citing the need for general deterrence in the community. Tamara appeals, arguing the sentence is unreasonable. Under Canadian sentencing law, what is the correct standard of appellate review for a sentence?
Answer: Appellate courts may only interfere with a sentence if it is demonstrably unfit, meaning the sentencing judge erred in principle or the sentence is clearly unreasonable.
The established Canadian appellate standard for sentencing review is that a court of appeal may only intervene if the sentencing judge committed an error in principle that had an impact on the sentence, or if the sentence is demonstrably unfit: see R v Lacasse 2015 SCC 64. Departing significantly above the established range without adequate justification may render a sentence demonstrably unfit. Option A (de novo review) and option C (correctness) are wrong — sentencing attracts significant deference. Option D incorrectly limits review to constitutional challenges. Option E (palpable and overriding error) applies to factual findings, not sentencing fitness.
6. During a confrontation, Omar is attacked by an assailant wielding a knife. Omar grabs a nearby bottle and strikes the assailant, fracturing his skull. The assailant dies. Omar is charged with manslaughter and raises self-defence. The trial judge instructs the jury that self-defence is only available if the force used was 'exactly proportionate' to the threat. Is this instruction correct under Canadian law?
Answer: No; under s. 34 of the Criminal Code, self-defence requires that the accused's acts be reasonable in the circumstances, considering all relevant factors including the nature of the threat, the means available, and whether other options existed; exact proportionality is not required.
Section 34 of the Criminal Code (as amended in 2012) provides that a person is not criminally responsible if they reasonably believe force or the threat of force is being used against them, the act is committed for the purpose of defending themselves, and the act is reasonable in the circumstances. The instruction demanding 'exact proportionality' imposes a stricter standard than the statutory 'reasonableness in the circumstances' test, which considers multiple factors under s. 34(2). Option A overstates the proportionality requirement. Option C omits the objective reasonableness component. Option D is wrong — self-defence is available even where the victim dies. Option E ignores proportionality entirely, which is a listed factor under s. 34(2).
7. Brigitte is charged with break and enter. The Crown discloses most of its file but withholds a police informant's identity, claiming the information is protected by informer privilege. Brigitte argues she needs the informant's identity to make full answer and defence. The trial judge refuses disclosure. Is the trial judge correct?
Answer: Yes; informer privilege is a near-absolute common law rule that protects informant identity; it overrides disclosure obligations unless the innocence-at-stake exception applies and Brigitte can demonstrate the information is necessary to establish her innocence.
R v Stinchcombe (1991) SCC established a broad Crown disclosure duty, but the Supreme Court has consistently held that informer privilege is a near-absolute common law rule that can override disclosure: see R v Leipert [1997] 1 SCR 281. The only recognized exception is the 'innocence at stake' exception, where the accused demonstrates the information is necessary to establish innocence. Option A incorrectly states Stinchcombe abolished all privilege exceptions. Option C overstates the accused's ability to displace privilege by mere assertion. Option D is wrong — there is judicial oversight through the innocence-at-stake exception. Option E is incorrect; informer privilege applies with equal force in criminal proceedings.
8. Lee is found in possession of a prohibited firearm in a province where mandatory minimum sentences apply. The trial judge finds the mandatory minimum of three years grossly disproportionate as applied to Lee's particular circumstances. The judge imposes a conditional sentence instead. The Crown appeals. Under s. 12 of the Charter, what is the correct analytical framework?
Answer: Under s. 12, a mandatory minimum violates the Charter only if it constitutes cruel and unusual punishment; the court assesses whether the minimum is grossly disproportionate either in the accused's case or in a reasonably foreseeable case to which the provision could apply.
The Supreme Court in R v Nur 2015 SCC 15 confirmed that s. 12 is violated where a mandatory minimum is grossly disproportionate either as applied to the offender before the court or in a reasonably foreseeable hypothetical application of the provision. A sentencing judge cannot simply substitute a conditional sentence on proportionality grounds without a s. 12 finding and remedy. Option A sets too low a threshold. Option C is wrong — s. 718.1 proportionality does not override a valid mandatory minimum. Option D severely and incorrectly narrows s. 12's scope. Option E reverses the order; the disproportionality finding comes before any s. 1 justification.
9. During a police interrogation, Constable Walsh tells Theo, who has invoked his right to counsel, 'Your lawyer isn't coming for hours; just tell me what happened and we'll sort this out.' Theo then makes a full confession. The defence applies to exclude the confession under s. 24(2) of the Charter. Which Charter right is most directly engaged?
Answer: Section 10(b) (right to retain and instruct counsel without delay), because police continued questioning after Theo invoked his right to counsel, violating the duty to hold off eliciting evidence.
When an accused invokes s. 10(b), police must cease eliciting evidence until the accused has had a reasonable opportunity to retain and instruct counsel: R v Manninen [1987] 1 SCR 1233. Continuing to interrogate Theo after he invoked his right to counsel and before counsel arrived directly violates s. 10(b) and the associated 'hold-off' duty. Option A (s. 7 only) is insufficiently specific — s. 10(b) is the more precisely applicable right. Option C is wrong; s. 11(c) applies at trial, not police questioning. Option D mischaracterizes a confession as a search. Option E may be incidentally relevant but does not capture the primary violation.
10. Asha and Ben are jointly charged with fraud. Asha wishes to call Ben as a defence witness; Ben has not yet testified in his own defence. The Crown objects, arguing Ben cannot be compelled by a co-accused. Which of the following is correct under Canadian law?
Answer: Ben is not compellable by Asha because a co-accused retains the right under s. 11(c) of the Charter not to be compelled to testify as a witness in proceedings against him.
Section 11(c) of the Charter provides that any person charged with an offence has the right not to be compelled to be a witness in proceedings against that person. A co-accused is a 'person charged with an offence' and cannot be compelled by another accused in the joint trial: see R v Lepage [1995] 1 SCR 654. Option A ignores the s. 11(c) protection available to an accused. Option C describes the Canada Evidence Act warning applicable to a compelled witness who is not an accused. Option D introduces a non-existent judicial discretion to override s. 11(c). Option E is wrong; s. 5 of the Canada Evidence Act governs compellability of witnesses generally but does not override a co-accused's s. 11(c) right.
11. Victor is charged with theft. The trial judge instructs the jury: 'If you find that Victor did the act of taking the property, you may presume he intended to steal it unless he proves otherwise on a balance of probabilities.' The defence objects to this instruction. Is the instruction constitutional?
Answer: No; the instruction creates a mandatory presumption that reverses the burden of proof on an essential element of the offence (mens rea), violating s. 11(d) of the Charter (presumption of innocence), and cannot be saved under s. 1.
Section 11(d) of the Charter enshrines the presumption of innocence; the Crown must prove every essential element of an offence beyond a reasonable doubt. A mandatory presumption that shifts the burden of disproving an essential element (here, mens rea) to the accused violates s. 11(d): R v Oakes [1986] 1 SCR 103. Such presumptions typically cannot be saved under s. 1 because reversing the burden on an essential element of a true crime fails the proportionality test in Oakes. Option A ignores the constitutional infirmity. Option C overstates the s. 1 justification. Option D is wrong because s. 11(d) is directly engaged, not just s. 7. Option E incorrectly treats rebuttability as sufficient to cure the constitutional defect.

10. Asha and Ben are jointly charged with fraud. Asha wishes to call Ben as a defence witness; Ben has not yet testified in his own defence. The Crown objects, arguing Ben cannot be compelled by a co-accused. Which of the following is correct under Canadian law?

Answer: Ben is not compellable by Asha because a co-accused retains the right under s. 11(c) of the Charter not to be compelled to testify as a witness in proceedings against him.

Section 11(c) of the Charter provides that any person charged with an offence has the right not to be compelled to be a witness in proceedings against that person. A co-accused is a 'person charged with an offence' and cannot be compelled by another accused in the joint trial: see R v Lepage [1995] 1 SCR 654. Option A ignores the s. 11(c) protection available to an accused. Option C describes the Canada Evidence Act warning applicable to a compelled witness who is not an accused. Option D introduces a non-existent judicial discretion to override s. 11(c). Option E is wrong; s. 5 of the Canada Evidence Act governs compellability of witnesses generally but does not override a co-accused's s. 11(c) right.

11. Victor is charged with theft. The trial judge instructs the jury: 'If you find that Victor did the act of taking the property, you may presume he intended to steal it unless he proves otherwise on a balance of probabilities.'

A mandatory presumption that shifts the burden of disproving an essential element (here, mens rea) to the accused violates s. 11(d): R v Oakes [1986] 1 SCR 103.
