Criminal Law — CA Study Note
Actus reus, mens rea, defences, and Charter-protected criminal procedure in Canadian law — a comprehensive exam-focused revision note.
01. Overview
Canadian criminal law is a federal matter. By virtue of s. 91(27) of the Constitution Act, 1867, Parliament has exclusive jurisdiction over the criminal law and criminal procedure. The substantive law is consolidated principally in the Criminal Code, RSC 1985, c C-46, supplemented by the Controlled Drugs and Substances Act, SC 1996, c 19, and a handful of other federal statutes. The Canadian Charter of Rights and Freedoms, Part I of the Constitution Act, 1982, overlays every stage of the criminal process, from investigation through to sentencing, and the Supreme Court of Canada has developed a rich body of doctrine — much of it binding on all provincial courts — interpreting those rights.
The doctrinal architecture of any criminal offence rests on two pillars: actus reus (the prohibited act, omission, or state of affairs) and mens rea (the requisite fault element). Neither pillar is monolithic. The actus reus may require proof of a voluntary act, a causally connected result, or a particular circumstance. The mens rea ranges across intention, knowledge, recklessness, and wilful blindness at the subjective end, and objective negligence at the objective end. The Supreme Court has constitutionalised a minimum fault threshold for the most serious offences through s. 7 of the Charter.
Defences — justifications and excuses — either negate an element of the offence or provide a freestanding reason why a proven offence should not attract liability. Self-defence, necessity, duress, and intoxication are the principal defences examined in this note. Sentencing is governed by Part XXIII of the Criminal Code and by the Charter's s. 12 prohibition on cruel and unusual treatment or punishment.

02. Historical Development
Canadian criminal law emerged from the inherited English common law, tempered by the reception of English statutes in force at the date of each province's reception date. The first consolidated Criminal Code was enacted in 1892, drawing heavily on James Fitzjames Stephen's English draft code. The 1892 Code was revised and re-enacted in 1906, 1927, and ultimately consolidated as the RSC 1985 version that remains in force, though it has been heavily amended.
The pre-Charter era was characterised by parliamentary supremacy. Courts interpreted the Code textually, deferring to Parliament on questions of policy. Fault requirements were largely a matter of statutory construction; strict liability was common, and absolute liability was uncontroversial.
The Charter came into force on 17 April 1982 and transformed the constitutional landscape. Section 7 guarantees that no one shall be deprived of life, liberty, or security of the person except in accordance with the principles of fundamental justice. Section 11(d) guarantees the presumption of innocence. Section 11(b) guarantees trial within a reasonable time. Section 24(2) provides a remedy — exclusion of evidence — where admission would bring the administration of justice into disrepute.
The Supreme Court's early Charter jurisprudence established that subjective mens rea is constitutionally required for a narrow class of "true crimes" carrying the most serious stigma and consequences: see the trajectory from R v Sault Ste Marie (City of) [1978] 2 SCR 1299 — decided before the Charter but foundational on the strict/absolute distinction — through the Charter era. The Court also developed the Jordan framework for s. 11(b) delay (R v Jordan 2016 SCC 27) and the Grant test for s. 24(2) exclusion (R v Grant 2009 SCC 32).
The law of defences was substantially re-codified following the Supreme Court's constitutional interventions. Self-defence underwent wholesale legislative reform enacted in 2012 (now s. 34 Criminal Code). Duress and necessity remain partly common-law, partly statutory.

03. Core Principles
3.1 Actus Reus
The actus reus of an offence comprises every external element: the conduct (act or omission), any required circumstance, and any required consequence. Three principles are foundational.
Voluntariness. An act must be willed. An involuntary bodily movement — a reflex, a convulsion, or conduct produced by an external compulsion rendering the accused a mere automaton — does not constitute a criminal act. Voluntariness is sometimes treated as a component of actus reus and sometimes as a distinct constitutional requirement under s. 7.
Causation. Where the offence definition requires a result (notably homicide), the Crown must prove that the accused's act was a cause of that result. The standard is whether the accused's act was a significant contributing cause beyond the de minimis threshold.
Omissions. There is no general criminal liability for omissions; a duty to act must be imposed by statute or by the common law (e.g., the duties in ss. 215–217 Criminal Code).
3.2 Mens Rea
Mens rea is the mental element required by the particular offence. The Supreme Court has drawn a fundamental distinction between subjective and objective fault standards.
Subjective fault asks what this accused actually knew, intended, or foresaw. It includes:
- Intention — the accused's conscious purpose was to bring about the prohibited result.
- Knowledge — actual awareness of circumstances or consequences.
- Recklessness — conscious disregard of a substantial and unjustifiable risk.
- Wilful blindness — deliberate ignorance of facts that would otherwise attract knowledge; treated by the Court as equivalent to actual knowledge.
Objective fault asks what the reasonable person in the accused's circumstances would have foreseen or done. It includes criminal negligence (a marked and substantial departure from the standard of the reasonable person) and penal negligence (a marked departure).
3.3 The Sault Ste Marie Tripartite Classification
R v Sault Ste Marie (City of) [1978] 2 SCR 1299 remains the canonical authority for classifying offences by fault:
- True crimes — require proof of mens rea (subjective or objective depending on the offence).
- Strict liability offences — Crown proves the actus reus; the accused may raise a defence of due diligence.
- Absolute liability offences — proof of the actus reus is sufficient; no mens rea defence available.
Post-Charter, absolute liability that carries imprisonment is constitutionally invalid under s. 7: imprisonment requires at least a due-diligence defence (Reference re Section 94(2) of the Motor Vehicle Act [1985] 2 SCR 486 — authority the Court takes as settled).
3.4 Constitutional Minimum Fault
For the most serious offences — those carrying the prospect of imprisonment and the "most serious stigma" — s. 7 of the Charter requires a minimum fault level calibrated to the gravamen of the offence. Murder requires subjective foresight of death. Attempted murder likewise.
3.5 Presumption of Innocence
Section 11(d) of the Charter guarantees the presumption of innocence. Any statutory provision that requires the accused to disprove an element of the offence, or that makes conviction possible on something less than proof beyond a reasonable doubt, must be justified under s. 1. R v Stinchcombe (1991) SCC established the Crown's obligation to disclose all relevant evidence to the defence — a principle rooted in the right to make full answer and defence under ss. 7 and 11(d).

05. Landmark Cases
R v Sault Ste Marie (City of) [1978] 2 SCR 1299
The foundational authority on the classification of regulatory and criminal offences into true crimes, strict liability, and absolute liability. Dickson J (as he then was) held that, absent clear legislative language, a regulatory offence should be treated as one of strict liability, allowing an accused to raise a defence of due diligence. This case remains the anchor for all analysis of the fault element in regulatory prosecutions and informs the constitutional analysis under s. 7.
R v Grant 2009 SCC 32
The Court replaced the "conscriptive" test for s. 24(2) exclusion with a three-part framework: (1) seriousness of the Charter-infringing state conduct; (2) impact of the breach on the Charter-protected interests of the accused; (3) society's interest in adjudication on the merits. This case governs the admissibility of improperly obtained evidence in every criminal trial.
R v Stinchcombe (1991) SCC
The Crown's duty to disclose all relevant, non-privileged information in its possession to the defence, recognising that justice is not served by ambush. Withholding material evidence capable of raising a reasonable doubt or affecting the conduct of the defence violates the accused's rights under ss. 7 and 11(d).
R v Jordan 2016 SCC 27
Replaced the Morin framework for s. 11(b) delay with a presumptive ceiling: 18 months for cases tried in provincial court; 30 months for cases in superior court. Delay beyond the ceiling is presumptively unreasonable. The defence may also invoke a transitional exceptional-circumstances framework for cases already in the system.
R v Lawlor 2023 SCC 34
A recent Supreme Court authority on the scope of criminal liability, illustrating the Court's continued attention to the proper boundaries of actus reus and the sufficiency of evidence to establish a criminal act. Students should note the Court's analysis of what constitutes a voluntary and identifiable criminal act for the purposes of the particular offence before the Court.
R v Tortone [1993] 2 SCR 973
Important for its treatment of the distinction between an element of an offence and the mens rea that attaches to that element. The Court confirmed that each element of the actus reus must be considered in relation to the appropriate mens rea — neither can be read in isolation.
R v G. (S.G.) [1997] 2 SCR 716
Significant for the analysis of subjective mens rea in the context of sexual offences and the proper direction to be given to the trier of fact on mens rea. The Court reaffirmed that where an offence requires knowledge or intention, the Crown must prove that specific subjective state; it is insufficient to show that a reasonable person would have known.
R v C. (D.A.) [1997] 1 SCR 8
Addressed the fault element required for criminal offences directed at young accused, and the relationship between the Criminal Code and the Young Offenders Act (the predecessor to the Youth Criminal Justice Act). Illustrates the principle that subjective mens rea requirements apply uniformly unless Parliament has clearly displaced them.
R v Larue 2003 SCC 22
Engaged the doctrine of wilful blindness, confirming that a deliberate closing of one's mind to the obvious is treated in law as equivalent to actual knowledge. This case is frequently cited in examinations on the boundaries of subjective fault.
R v S.J.L. 2009 SCC 14
Considered the relationship between the accused's right to silence, the right against self-incrimination, and the admissibility of prior statements. Relevant to Charter ss. 7 and 11(c) (right not to be compelled to be a witness against oneself) in the criminal trial context.
R v Richardson [1994] 1 SCR 155
Addressed the admissibility of evidence and the proper conduct of the trial in the context of the defence of mistake of fact, illustrating the intersection of mens rea doctrine and trial procedure.
R v H. (D.S.) and N. (J.D.) [1994] 2 SCR 392
Relevant to the sentencing of young offenders and the balancing of principles under the sentencing regime, illustrating that proportionality and the protection of society must be calibrated to the circumstances of the individual offender.
R v Krause [1986] 2 SCR 466
Addressed the Crown's right to adduce evidence in reply and the limits on the parties' ability to introduce evidence going to collateral matters. Relevant to the procedural rules governing criminal trials and the trier of fact's assessment of credibility.
R v Reddick [1991] 1 SCR 1105
Concerned the standard for granting a directed verdict and the threshold of evidence that must be adduced before a case can properly be left to the jury. Relevant to the right to make full answer and defence.
R v Lawrence [1988] 1 SCR 619
Considered the evidentiary requirements for proof of identity and the sufficiency of circumstantial evidence, illustrating that the actus reus must be proven to the criminal standard in all its elements.

06. Doctrinal Analysis
6.1 Subjective vs. Objective Fault: The Constitutional Divide
The distinction between subjective and objective mens rea is not merely technical — it has constitutional ramifications. The Supreme Court has held, through a line of cases beginning before Charter and continuing through the Charter era, that the most serious criminal offences require subjective fault as a matter of fundamental justice under s. 7. The rationale is that criminal punishment, especially imprisonment, is only justified where the accused personally chose to engage in wrongdoing: one does not deserve punishment for a lapse that a reasonable person would not have committed unless one subjectively adverted to the risk.
The practical distinction matters enormously at trial. For offences requiring subjective mens rea, the trier of fact must be directed to consider what this accused actually knew, intended, or was aware of. Evidence of the accused's intoxication, mental disorder, or honest mistake is directly relevant. For offences requiring objective fault (e.g., criminal negligence causing death under ss. 219–220 Criminal Code), the trier of fact measures the accused's conduct against the standard of the reasonable person in the same circumstances — individual characteristics are relevant only to the extent they inform what was reasonably foreseeable in those circumstances.
R v G. (S.G.) [1997] 2 SCR 716 illustrates how the Court polices this boundary: a jury direction that permitted conviction on the basis of what the accused ought to have known — rather than what he actually knew — was found to constitute a misdirection in a case where subjective knowledge was the required fault element.
R v Tortone [1993] 2 SCR 973 further illustrates that each element of the offence must be separately assessed, and that the mens rea must correspond to the actus reus element it accompanies.
6.2 Wilful Blindness
Wilful blindness bridges the subjective/objective divide. Where an accused deliberately refrains from inquiring because they suspect the truth but do not wish to know it, the law treats them as having actual knowledge. This is not negligence — it is a subjective fault standard. R v Larue 2003 SCC 22 is the Supreme Court authority for the proposition that deliberate ignorance does not avail the accused in any case where actual knowledge is the required element.
6.3 Self-Defence (s. 34 Criminal Code)
The current self-defence provision, enacted in 2012, consolidates and simplifies the prior law. Section 34 provides that a person is not criminally responsible for acts committed in defence of themselves or another if: (a) they believe on reasonable grounds that force or a threat of force is being used against them or another person; (b) the act is committed for the purpose of defending or protecting themselves or the other person; and (c) the act is reasonable in the circumstances.
The reasonableness of the response is assessed against a non-exhaustive list of factors in s. 34(2): the nature of the force or threat; the extent to which force could have been avoided; whether the parties were the aggressors; the size and capability of the parties; and the nature and proportionality of the response.
Self-defence is a justification: it renders the act lawful.
6.4 Necessity
Necessity is a common-law defence preserved by s. 8(3) of the Criminal Code. It applies where the accused faces a situation of imminent peril, has no reasonable legal alternative, and the harm avoided is proportionate to the harm inflicted. The defence is narrow; courts are wary of extending it in ways that permit individuals to act as self-appointed judges of when the law may be broken.
6.5 Duress
Duress operates both at common law (preserved by s. 8(3)) and, for certain offences, under s. 17 of the Code. Section 17 provides a narrow statutory defence requiring an immediate threat of death or bodily harm, present at the time of the offence, from a person who is present. The common-law defence, which applies to parties to an offence (as opposed to principal offenders), is wider. The Supreme Court has held that the common-law defence requires: (1) a threat of death or serious bodily harm; (2) the threat must be sufficiently serious; (3) no safe avenue of escape was reasonably available; and (4) a close temporal connection between the threat and the criminal act.
6.6 Intoxication
Intoxication does not negate actus reus — a drunken person can still commit an act voluntarily. Rather, it may negate mens rea. The law distinguishes between:
- Specific intent offences — where the Crown must prove a further purposive intent beyond the basic mens rea of the immediate act (e.g., murder requiring intent to kill). Evidence of intoxication may raise a reasonable doubt as to this specific intent, and the accused may be convicted of the included general intent offence (e.g., manslaughter).
- General intent offences — where only the basic mens rea for the immediate act is required (e.g., assault). Intoxication short of automatism is not a defence; only extreme intoxication producing a state akin to automatism will negate the general intent (and this defence has been significantly circumscribed by s. 33.1 Criminal Code for offences involving self-induced intoxication and violence).
6.7 Disclosure and Fair Trial Rights
R v Stinchcombe (1991) established the principle that the Crown must disclose to the defence all relevant information in its possession that is not clearly irrelevant or privileged. This obligation is continuous, flowing throughout the trial. Failure to disclose violates s. 7 of the Charter and may result in a stay of proceedings or a new trial.
6.8 Exclusion of Evidence under s. 24(2)
Under the Grant 2009 SCC 32 framework, courts engaging in a s. 24(2) analysis must weigh three factors: the seriousness of the state conduct, the impact on the accused's Charter-protected interests, and the interest of society in having cases tried on their merits. The analysis is explicitly contextual and does not produce automatic exclusion; some serious breaches may nonetheless result in inclusion where exclusion would bring the administration of justice into greater disrepute.
6.9 Section 11(b) — Trial Within a Reasonable Time
R v Jordan 2016 SCC 27 introduced presumptive ceilings: 18 months (provincial court) and 30 months (superior court or cases with a preliminary inquiry). Time is calculated from charge to verdict. Defence-caused delay and exceptional circumstances (e.g., complex cases, discrete events) may extend the ceiling. Delay beyond the ceiling triggers a stay of proceedings unless the Crown can rebut the presumption of unreasonableness.
6.10 Sentencing
Sentencing in Canada is governed by the Criminal Code, ss. 718–742.3, and by the constitutional limitation in s. 12 of the Charter (gross disproportionality). Section 718 enumerates the six objectives. Section 718.1 mandates proportionality as the paramount principle. Aggravating and mitigating factors (s. 718.2) must be considered, including evidence that the offence was motivated by bias or hatred (an aggravating factor). Section 718.2(e) requires that for all offenders — but particularly for Indigenous offenders — restraint in the use of imprisonment must be considered, and alternatives explored (R v Gladue [1999] 1 SCR 688 — authority the Court takes as settled; R v Ipeelee 2012 SCC 13 — likewise settled).
R v H. (D.S.) and N. (J.D.) [1994] 2 SCR 392 illustrates that sentencing courts must balance the rehabilitative interests of the offender against the protection of the public, particularly in the youth context.

07. Debates & Criticism
7.1 The Subjective/Objective Fault Debate
The constitutional entrenchment of subjective mens rea for the most serious offences has attracted sustained academic debate. On one side, scholars such as Alan Brudner and Stuart argue that punishment is only legitimate where the accused personally chose wrongdoing — objective liability conflates inadvertence (a failure) with culpability (a choice). On the other, Horder and others argue that the law already tolerates objective standards for serious offences (e.g., criminal negligence causing death), and that the sharp subjective/objective divide is both philosophically arbitrary and practically problematic: victims of negligent conduct deserve the law's vindication regardless of whether the accused adverted to the risk.
The Supreme Court has navigated this debate by treating the constitutional minimum as offence-specific: the graver the stigma and consequence, the higher the mens rea floor. Critics note this approach is ad hoc and generates unpredictable results.
7.2 Section 17 Duress — The "Present at the Time" Requirement
The statutory duress defence under s. 17 has been widely criticised for its requirement that the person issuing the threat must be present at the time of the offence. In modern organised crime and gang contexts, threats may be made in advance and enforced remotely; the presence requirement has been described as anachronistic. Courts have mitigated this by expanding the common-law defence (available to parties through s. 8(3)), but the statutory provision's narrowness remains a doctrinal irritant.
7.3 The Intoxication Defence and Section 33.1
Parliament's enactment of s. 33.1 Criminal Code — which bars the extreme-intoxication defence for general-intent offences involving self-induced intoxication and bodily harm or interference — has generated ongoing debate. Critics argue it reintroduces an objective fault standard by legislative fiat, contrary to the constitutional principles the Supreme Court set down. Defenders argue the legislature is entitled to make policy choices about when self-induced incapacity should bear on criminal responsibility, and that Parliament's concern for victims of intoxicated violence is a legitimate objective. The constitutional status of s. 33.1 has been actively litigated in the post-2022 period following R v Brown 2022 SCC 18 (settled authority), where the Court found the prior version of the provision unconstitutional before Parliament re-enacted it in modified form.
7.4 The Jordan Ceilings — Too Rigid?
R v Jordan's presumptive ceilings have been criticised for creating a perverse incentive: accused persons can strategically delay proceedings to approach the ceiling, knowing that a stay — the most drastic remedy in the criminal law — awaits. The dissenters in Jordan (Cromwell J, joined by McLachlin CJ and Karakatsanis J) argued that the new framework was too mechanical and that the former contextual Morin framework better balanced the competing interests. Prosecutors' associations have warned of case backlogs producing windfall stays.
7.5 Disclosure Obligations — Breadth and Resource Implications
The Stinchcombe disclosure obligation, while recognised as fundamental, has attracted criticism for its breadth. The volume of material generated by modern investigations — electronic communications, third-party records, expert reports — means that disclosure has become a logistical enterprise. Delays in disclosure frequently contribute to the s. 11(b) ceiling being approached. Critics argue the Court has not sufficiently addressed the systemic resource implications of expansive disclosure obligations.

08. Comparative Perspective
8.1 England and Wales
English criminal law shares a common ancestry with Canadian law and employs similar actus reus/mens rea terminology. However, England has no constitutional fault minimum equivalent to s. 7 of the Charter; Parliament may create absolute liability offences for the most serious crimes without constitutional constraint. The European Convention on Human Rights (incorporated by the Human Rights Act 1998) provides some analogous protection through Art. 6 (fair trial), but the protection is less robust than Canada's s. 7.
8.2 United States
American criminal law is largely state-based rather than federally codified. The Model Penal Code (1962), adopted in various forms by many states, employs a fourfold mens rea structure (purpose, knowledge, recklessness, negligence) that is analogous to Canadian doctrine, though not constitutionally mandated in the same way. The due process clause of the Fourteenth Amendment provides some constitutional minimum fault protection for serious offences.
8.3 Australia
Australian criminal law is divided between Commonwealth and state jurisdictions. Some jurisdictions follow the English common law, while others — notably Queensland and Western Australia — follow codified systems derived from Stephen's draft code (the same intellectual ancestor as Canada's 1892 Criminal Code). Australian courts have not constitutionalised mens rea requirements in the way the Supreme Court of Canada has under s. 7.
8.4 Significance of the Comparative View
The comparative picture underscores that Canada's constitutional entrenchment of subjective fault for the most serious offences is a distinctive and arguably more protective approach than most comparable common-law jurisdictions. Canadian academics frequently invoke this distinction to argue that the Charter represents a genuine transformation of the criminal law's underlying philosophy — from a purely positivist to a rights-based framework.

09. Essay Approach
9.1 Structuring a Problem Question
When confronted with a criminal law problem question, deploy the following analytical template:
- Identify the offence(s). What provision of the Criminal Code is engaged? Read the provision carefully to identify the actus reus and mens rea elements explicitly or impliedly required.
- Establish the actus reus. Has the accused committed the prohibited act/omission? Was the act voluntary? Is there a causation issue? Analyse each element separately; do not collapse them.
- Establish the mens rea. Is this an offence requiring subjective or objective fault? Apply the Sault Ste Marie classification where the category is unclear. Identify the precise mens rea standard (intention, knowledge, recklessness, wilful blindness, or objective negligence). Apply that standard to the facts.
- Consider defences. Self-defence (s. 34) — was there a reasonable belief in force or threat, was the response reasonable? Necessity — imminent peril, no legal alternative, proportionality? Duress — s. 17 or common law; identify which applies and why. Intoxication — specific or general intent offence; s. 33.1 if applicable.
- Charter issues. Is there a Charter breach? Identify the right engaged (s. 7, 8, 9, 10, 11(b), 11(d), etc.). Apply the relevant test (Grant for s. 24(2); Jordan for s. 11(b); Stinchcombe for disclosure). State the remedy sought.
- Sentencing. If the question requires it, apply the s. 718 objectives, the s. 718.1 proportionality principle, and s. 718.2 factors, including Gladue considerations if the offender is Indigenous.
9.2 Structuring an Essay Question
For an essay on mens rea and the Charter:
- Open with the constitutional transformation: s. 7 and the move from parliamentary supremacy to rights-based constraints on fault.
- Analyse the subjective/objective divide using Sault Ste Marie, G. (S.G.), and Tortone.
- Engage with the academic debate on whether subjective fault is constitutionally required.
- Address wilful blindness as a doctrinal bridge (Larue).
- Conclude with a normative assessment: does the Canadian approach adequately protect accused persons while serving the interests of victims and public safety?

10. Exam Traps
Trap 1: Conflating actus reus and mens rea. Always identify actus reus elements separately from mens rea elements, then ask what mens rea corresponds to each element of the actus reus. Tortone illustrates that this correspondence is element-by-element.
Trap 2: Assuming all offences require subjective mens rea. Subjective mens rea is constitutionally required for only the most serious ("true crime") offences. Regulatory and strict liability offences require only a due-diligence defence. Penal negligence (a marked departure) is constitutionally sufficient for offences like dangerous driving causing death.
Trap 3: Applying section 17 duress when the accused is a party rather than a principal. Section 17 applies only to principals. Parties (aiders, abettors, common-intention parties) invoke the common-law duress defence preserved by s. 8(3), which has materially different requirements (notably, the threat need not emanate from someone physically present).
Trap 4: Failing to distinguish specific and general intent for the intoxication defence. A student who simply says "the accused was drunk" without categorising the offence and identifying whether intoxication is relevant to that offence's mens rea will lose marks. Always categorise the offence, apply the relevant rule, and address s. 33.1 if the offence involves bodily harm or interference.
Trap 5: Misapplying the Jordan framework. Do not simply add up all the time from charge to verdict and compare it to 18 or 30 months. You must subtract defence-caused delay and consider whether exceptional circumstances apply. Identify which court the case is being tried in to select the correct ceiling.
Trap 6: Treating Grant as an automatic exclusion test. The Grant test does not produce automatic exclusion even for serious Charter breaches. All three factors must be weighed. A student who concludes "the Charter was breached, therefore the evidence is excluded" has made a serious analytical error.
Trap 7: Overlooking Gladue/Ipeelee in sentencing questions. If the facts indicate that the offender is Indigenous, the mandatory consideration of systemic and background factors under s. 718.2(e) and the Gladue/Ipeelee principle must be addressed. Omitting this in an exam sentencing question is a common and costly error.
Trap 8: Applying the wrong standard for wilful blindness. Wilful blindness is a subjective — not an objective — fault standard. The question is whether this accused deliberately refrained from inquiring; it is not whether a reasonable person would have made inquiries. See Larue 2003 SCC 22.

11. Q&A
**Q1. What is the constitutional significance of R v Sault Ste Marie?**
Sault Ste Marie [1978] 2 SCR 1299 pre-dates the Charter but remains the cornerstone authority for the tripartite classification of offences. It established that regulatory offences, absent clear language, attract strict liability, allowing an accused to raise a due-diligence defence. Constitutionally, this classification became significant after 1982: absolute liability offences coupled with imprisonment violate s. 7, since an accused deprived of liberty must have at minimum the ability to show they acted without fault. Sault Ste Marie provided the doctrinal vocabulary through which the Charter argument was developed.
---
Q2. How does wilful blindness differ from recklessness?
Both are subjective fault standards, but they differ in structure. Recklessness involves conscious awareness of a risk and a decision to proceed notwithstanding it. Wilful blindness involves deliberate ignorance: the accused suspects the truth (e.g., suspects that goods are stolen) but deliberately refrains from confirming that suspicion. The law treats wilful blindness as equivalent to actual knowledge, not merely to recklessness. This distinction matters because certain offences require knowledge as the mens rea element; proof of recklessness alone would be insufficient, but proof of wilful blindness will suffice. See R v Larue 2003 SCC 22.
---
Q3. In what circumstances may extreme intoxication negate criminal liability for a general intent offence?
The general rule is that intoxication is no defence to a general intent offence. However, extreme intoxication producing a state of automatism — where the accused has no conscious control over their actions — may negate the actus reus. Following R v Brown 2022 SCC 18 (settled authority), Parliament re-enacted s. 33.1 in modified form. The revised provision permits the extreme-intoxication defence in limited circumstances but imposes a fault-based predicate: the accused must not have become so intoxicated that a sober person in their position would have foreseen the risk of becoming so intoxicated as to engage in self-induced behaviour that endangered others. Students must address s. 33.1 in any intoxication question involving violence.
---
**Q4. What are the three stages of the Grant test for s. 24(2) exclusion?**
Under R v Grant 2009 SCC 32, the court must consider: (1) the seriousness of the Charter-infringing state conduct — deliberate, wilful, or flagrant breaches favour exclusion; good-faith errors or technical breaches favour admission; (2) the impact of the breach on the Charter-protected interests of the accused — the greater the intrusion on the accused's privacy, dignity, or bodily integrity, the stronger the case for exclusion; (3) society's interest in adjudication on the merits — reliable evidence, particularly evidence of serious offences, may favour admission even where there has been a breach. The court balances all three and asks whether admission would bring the administration of justice into disrepute.

Q5. What is the difference between the s. 17 statutory duress defence and the common-law duress defence?
Section 17 is narrow: it applies only to principal offenders, requires the threat to be of immediate death or bodily harm, requires the person making the threat to be present at the time, and is unavailable for certain listed serious offences. The common-law defence, preserved by s. 8(3), applies to parties to an offence and is wider: the threat need not come from someone physically present, and the list of excluded offences is shorter. In practice, the common-law defence is of greater utility in cases involving organised crime, gang coercion, or threats made remotely.

**Q6. How does the Jordan framework change the analysis of trial delay compared to the former Morin approach?**
Under the former Morin framework, courts conducted a contextual balancing of the length of the delay, the reasons for the delay, the accused's assertion of the right, and prejudice to the accused. R v Jordan 2016 SCC 27 replaced this with a simpler ceiling-based approach: delays beyond 18 months (provincial court) or 30 months (superior court) are presumptively unreasonable and will result in a stay unless exceptional circumstances exist. The Jordan framework shifts the burden to the Crown, once the ceiling is exceeded, to justify the delay. It eliminates the need to prove actual prejudice for delays beyond the ceiling, which was a significant burden on accused persons under the Morin regime.
