Canadian Medical Ethics for MCCQE: Complete Cheat Sheet

Ethics questions on the MCCQE Part 1 aren't hard because the concepts are complicated. They're hard because Canadian law doesn't work the way most people assume — and the exam loves testing the gap between what feels right and what's actually legal.

If you trained outside Canada, this is probably your biggest blind spot. If you trained inside Canada, you probably covered this once in second year and forgot half of it.

Here's everything you actually need to know.

MAID (Medical Assistance in Dying)

Canada has a highly regulated framework for Medical Assistance in Dying (MAID). The MCCQE Part 1 tests this topic frequently, focusing on eligibility, safeguards, and the physician's duties when they object.

Eligibility and the Two-Track System

Decriminalized in the Carter v. Canada (2015) decision and formalized via Bill C-14, the Criminal Code exemptions for MAID were updated in 2021 (Bill C-7) to establish a two-track system:

• Track 1: Natural death is reasonably foreseeable
  • Age and Capacity: The patient must be at least 18 years old, eligible for publicly funded health services in Canada, and capable of making healthcare decisions.
  • Condition: Must have a grievous and irremediable medical condition (advanced state of irreversible decline in capability, causing intolerable physical or psychological suffering).
  • Safeguards: Requires a signed and dated written request witnessed by one independent witness (must be at least 18 years old and not directly involved in the patient's care or a beneficiary). Two independent medical or nurse practitioners must confirm eligibility. The patient must be given the opportunity to withdraw consent immediately before the administration of the substance.
• Track 2: Natural death is NOT reasonably foreseeable
  • Safeguards: A minimum assessment period of 90 clear days is mandatory between the start of the first assessment and the day MAID is provided (unless loss of capacity is imminent). One of the two assessing practitioners must have expertise in the specific condition causing the patient's suffering. The patient must be informed of, and seriously consider, all reasonable means to relieve their suffering (such as palliative care, counseling, and community support).

!IMPORTANTBill C-62 Update (2024): On February 29, 2024, the federal government passed Bill C-62, which postpones MAID eligibility for individuals whose sole underlying medical condition is a mental illness to March 17, 2027. On the exam, a patient requesting MAID solely for depression or schizophrenia is currently ineligible.

Conscientious Objection and Effective Referral

The Supreme Court of Canada established that no physician is compelled to participate in or perform MAID. However, regulatory colleges (such as the College of Physicians and Surgeons of Ontario) require objecting physicians to provide an effective referral.

An effective referral means you must coordinate a transfer of care to a non-objecting provider or central access service in a timely manner. You cannot simply refuse and leave the patient to find resources on their own.

Capacity Assessment and HCCA

Under the Ontario Health Care Consent Act (HCCA) and similar provincial acts, capacity is presumed. The clinician proposing the treatment is responsible for assessing capacity. For a deep-dive breakdown of the ACE evaluation tool and Substitute Decision-Maker hierarchies, see our dedicated MCCQE Capacity Assessment Guide.

The Two-Fold Test for Capacity

To be deemed capable of consenting to a treatment, a patient must meet a two-fold test:

1. Understanding: Can the patient understand the clinical information relevant to the decision (such as the nature of their condition, the proposed treatment, and alternatives)?
   • Test: Ask the patient to explain the information in their own words.
2. Appreciation: Can the patient appreciate the reasonably foreseeable consequences of a decision or lack of a decision?
   • Test: Ask the patient to explain how that information relates to their personal life and values (e.g., acknowledging their own symptoms and how treatment options affect them).

Substitute Decision-Makers (SDMs)

If a patient is assessed as incapable of consenting to a treatment, consent must be obtained from a Substitute Decision-Maker (SDM). The legal hierarchy in Ontario is:

1. Guardian of the Person: Appointed by the court (highest authority).
2. Attorney for Personal Care: Named in a Power of Attorney (POA) document.
3. Representative: Appointed by the Consent and Capacity Board (CCB).
4. Spouse or Partner.
5. Child or Parent (or Children's Aid Society if they are a ward).
6. Parent with only right of access.
7. Sibling.
8. Any other relative (by blood, marriage, or adoption).
9. Public Guardian and Trustee: The SDM of last resort if no other individual is available or willing.

Principles of SDM Decision-Making

An SDM does not make decisions based on what they want. They must follow two principles in order:

1. Prior Expressed Wishes: Act in accordance with any wishes the patient expressed while capable (either verbally or in writing). More recently expressed wishes take priority over older ones.
2. Best Interests: If the patient's prior wishes are unknown, the SDM must act in the patient's best interest, taking into account the patient's values, beliefs, expected clinical improvement, and whether benefits outweigh the risks of harm.

If you believe an SDM is not acting in accordance with these principles, you must challenge their decision by applying to the provincial review board (such as the Consent and Capacity Board in Ontario).

Informed Consent and Legal Precedents

Informed consent is a process of communication and shared decision-making, not a signature on a form. A signed consent form is only evidence of consent; it does not replace the conversation.

Withdrawing Consent: Ciarlariello v. Schachter

This is a highly tested Supreme Court of Canada case on the MCCQE:

• A patient has the right to withdraw consent at any point during a medical procedure.
• If consent is withdrawn during a procedure, the physician must stop the treatment immediately, unless stopping would put the patient's life or physical safety at imminent risk.
• To resume, if there has been a material change in circumstances, the physician must re-explain the procedure and risks. If there has been no material change, simple verbal assent to continue is sufficient.

Minor Consent and the Quebec Exception

In all Canadian provinces except Quebec, there is no fixed age of consent. Consent depends entirely on decision-making capacity (the mature minor doctrine). If an adolescent understands the treatment and appreciates its consequences, they can consent or refuse independently of their parents.

• The Quebec Exception: Under the Civil Code of Quebec, the age of consent for medical care is 14 years old.
  • Minors aged 14 and older can consent independently to care that is clinically necessary. However, if they are hospitalized for more than 12 hours, their parents must be notified.
  • Minors under 14 years old require parent or guardian consent, except for emergency care.

Confidentiality and the Coroner's Act

Patient privacy is a right, and confidentiality is a physician's duty. However, public interest and statutory laws override confidentiality in specific scenarios.

The Duty to Warn

You must breach confidentiality to warn third parties if there is an imminent risk of serious bodily harm or death to an identifiable person or group. This is the Tarasoff principle, which is active in Canadian case law.

The Coroner's Act

In Ontario (and via similar provincial statutes), you are legally required to immediately report a death to a coroner or police officer if it occurs:

• Due to violence, negligence, misconduct, misadventure, or malpractice.
• Suddenly and unexpectedly.
• During pregnancy or is attributable to pregnancy (maternal mortality).
• From a disease that was not treated by a qualified medical practitioner.
• Under suspicious circumstances.
• Following Medical Assistance in Dying (MAID).

Frequently Asked Questions

What happens if a patient refuses treatment but is deemed incapable?

In a non-emergent situation, you must seek consent from their Substitute Decision-Maker. If the patient challenges the finding of incapacity, they have the right to a hearing before a provincial tribunal, such as the Consent and Capacity Board (CCB) in Ontario.

Can a patient write a lock box instruction on their chart?

Yes. Under privacy legislation, a capable patient can instruct that specific parts of their medical record not be shared with other healthcare providers in their circle of care. This is known as a lock box. You must respect this instruction unless a statutory exception or emergency exists.

What is the difference between a Power of Attorney and a Guardian?

A Power of Attorney for Personal Care is a legal document signed by a capable person naming an SDM. A Guardian of the Person is a representative appointed by a court for an incapable person who did not establish a POA. A Guardian sits higher in the SDM hierarchy.

Conclusion

Passing the MCCQE Part 1 requires you to know these Canadian-specific legal cases and acts. By understanding Ciarlariello v. Schachter, the HCCA, and the exact MAID rules under Bill C-62, you can confidently answer the ethics questions.
