As of 2026-08-19 the exclusion of mental illness as the sole underlying condition for medical assistance in dying in Canada lapses by operation of statute on 2027-03-17 — the statutory duty was to reconstitute a review committee by 2026-02-28, and that duty ends at the report tabled on 2026-06-17

What is happening?

Canada legalized medical assistance in dying in 2016. Bill C-7, which received royal assent on 2021-03-17, widened eligibility beyond people whose natural death is reasonably foreseeable and at the same time barred requests where a mental illness is the sole underlying medical condition. The bar was written as a temporary one. The statute set it to lapse on 2023-03-17 with no further vote required.

The date has moved twice, each time by a new Act of Parliament. Bill C-39, royal assent 2023-03-09, moved it to 2024-03-17. Bill C-62, royal assent 2024-02-29, moved it to 2027-03-17 and added a statutory duty to reconstitute a joint parliamentary review committee by 2026-02-28.

That committee was reconstituted by the deadline. On 2026-06-17, ten years after legalization, it tabled an 88-page report recommending that the Criminal Code be amended so that mental illness as a sole underlying condition is excluded indefinitely. The recommendation carries no legal force. As of 2026-08-19 no statute has passed in either direction, so the legal default remains the automatic date of 2027-03-17.

Two other tracks are open and neither controls the outcome. A Charter challenge to the exclusion was filed in the Ontario Superior Court of Justice in 2024-08 and an urgent relief motion was filed in 2026-05; the litigation is pending. A private member bill that would write a permanent exclusion into the Criminal Code had a first reading on 2025-06-20 and a second reading debate in 2025-12, and had not been passed as of 2026-08-19.

Whose problem is this?

The body that has to decide is the same body that wrote the deadline into the statute, and nothing outside it can force the decision. A recommendation from its own review committee is not a bill, and the date arrives whether or not anyone votes.

Where does this problem end?

The boundary here is not about whether the practice should exist. It is about a decision that a statute required someone to reach and that has not been reached, and the same gap would be visible whichever way the decision eventually went.

What is the state now, and what should it be?

Now

Needs a new measurementthe target state: no source opened here names a date by which the federal government intends to announce a decision, and none names a test of readiness that could be passed or failed. The 2024 deferral was described in public remarks as a signal that the system should be ready within two years, and the federal health department has listed preparation categories such as education, training, engagement with Indigenous communities, quality review and research. Nothing opened here states what completion of any of those categories would look like, who would certify it, or what follows if it is not reached before 2027-03-17.

How big is it?

Between 32.4 million and 41.4 million people live under the provision whose start date is unsettled. The upper bound is the population of Canada on 2026-04-01, 41,417,056. The lower bound subtracts the population of Quebec on the same date, 9,016,222, because Quebec has excluded mental disorder other than neurocognitive disorder under its own statute since 2023-06-07, so the federal outcome would not change what is available there. Both figures were published by Statistics Canada on 2026-06-17.

This number counts residents who live under a criminal-law provision, not people who would ever make a request. No source opened here gives a Canadian estimate of how many requests would be made on the ground of mental illness alone, and the absence of that estimate is itself part of the record.

The federal count that does exist measures something else. There were 16,499 deaths by medical assistance in dying in Canada in 2024, which was 5.1 percent of all deaths that year and 6.9 percent more than the year before, and 732 of them fell under the track for people whose natural death is not reasonably foreseeable, against 469 in 2022. That track does not include mental illness as a sole underlying condition, because that ground is excluded today, so none of these figures measures the group the 2027 date would affect.

Under what conditions does it arise?

1. The default is not a decision. The exclusion lapses on a fixed date by operation of the statute. Keeping it requires a new Act, and moving the date again also requires a new Act. Doing nothing produces an outcome that nobody has voted for.

2. The review duty and the decision duty were separated. Bill C-62 obliged Parliament to reconstitute a joint committee by 2026-02-28. It did not oblige anyone to act on what that committee found, and it attached no deadline to a response. The committee met the duty that existed and reported. Nothing in the statute converts that report into law.

3. Readiness was never defined. The three-year deferral was presented publicly as time for the system to prepare. No source opened here sets out what preparation would have to be complete, who would measure it, or what the measurement would be compared against.

4. Two tracks run at once and neither controls the other. The parliamentary track has produced a recommendation with no legal force and the court track has produced no ruling yet. Neither has a date that binds the other, and the statutory date arrives regardless of where either stands.

5. Criminal law is federal and health delivery is provincial. One province has already legislated its own permanent exclusion, so the federal outcome does not determine availability uniformly across the country. The practical effect of the same federal date is therefore already different in different places.

What has been tried?

Every item in this list either studies the question or moves the date. The two that would settle it are a bill that has not been voted on and a case that has not been ruled on, and both were in that state on 2026-08-19.

What was found?

Why is it still unsolved?

Institutional gap — the statute created a duty to review and a date that arrives by itself, and it created nothing that turns a review into a decision.

A sunset clause converts silence into an outcome. Both of the outcomes anyone has asked for require an Act of Parliament, and the outcome that nobody has to ask for is the one that follows if no Act passes. That inverts the usual position, in which a body that cannot agree produces nothing. Here a body that cannot agree still produces a result, and the result is indistinguishable from a decision to everyone standing outside the process.

The second part is that the review duty ends at the report. Bill C-62 attached a deadline to reconstituting the committee and attached no deadline to anything after it. The committee did what the statute required and tabled its report on 2026-06-17. The only instrument on the record that would enact what it recommended is a private member bill, which reached a second reading debate in 2025-12 and has not been voted on. Responses to the report closed on 2026-07-11, and no statement announcing a decision appears in any source opened here after 2026-06-19.

The third part is that the deferral was granted without a test attached. When a deadline is moved on the ground that a system needs time, the question that follows is what the system has to reach. Nothing opened here answers it. Preparation categories have been listed, but a list of categories cannot be passed or failed, so there is no moment at which the question resolves itself and no reading that would tell anyone the answer is due.

The fourth part is that the two tracks are not synchronized with the date. The litigation is pending and has no ruling. The statutory date is fixed and moves for nobody. Neither process is waiting for the other, and the calendar is the only thing that is certain to act.

What observation would mean it is solved?

The question tracked here is whether the decision is made, not which way it goes. Neither direction is treated as the solution in this document, and an outcome in either direction would close the same gap.

Candidates — (a) Parliament passes a statute that settles the question in either direction, with the text and the date of royal assent on the record (b) the federal government publishes a decision with reasons and a date before 2027-03-17 (c) a court ruling with final effect settles whether the exclusion stands.

(a) is the only one that closes the gap by itself. A statute is the instrument the sunset clause responds to, and until one passes the date keeps counting down whatever else has been said.

(b) is weaker than it looks. A published intention is not an enactment, and a government that announces a direction still has to find room in the parliamentary calendar for a bill. An announcement can also be superseded by a later Parliament, and the date arrives regardless.

(c) does not close it either. The litigation was pending as of 2026-08 and a ruling at first instance can be appealed, so a decision in that track is not automatically final. A ruling could also settle the constitutional question while leaving the commencement date untouched, which would move the law without answering what the statute asked Parliament to answer.

The date arriving is not a solution. If 2027-03-17 passes with no statute, the exclusion lapses because nobody acted. That is the mechanism working exactly as written, and it is the one outcome that could be reached without any of the three observations above ever occurring.

What is it connected to?

Fills with researchsunset clauses and automatic commencement in other federal statutes, statutory review committees and what becomes of their recommendations, capacity in mental health services, and the division of health jurisdiction between the federal and the provincial levels. Relation type and evidence grade were not confirmed in this round.

What these sources do not say

• Why three years was chosen. Public remarks in 2024 described the period as a signal that the system should be ready within two years. No source opened here states which preparation items that period was estimated from, or by whom.
• How many requests would be expected on the ground of mental illness alone in Canada. No source opened here gives a figure. The 2022 expert panel dealt with how such requests would be handled rather than how many there would be, and the preparation categories listed by the federal health department contain no expected-volume item.
• The vote behind the June 2026 recommendation. Several sources agree that a majority supported it. None opened here gives the numbers for and against.
• What the federal government did after responses closed on 2026-07-11. The most recent public statement in any source opened here is from 2026-06-19. No source opened here reports a government bill, a formal response, or a further statement after that date.
• How far provinces and territories have prepared for a 2027-03-17 start. The preparation categories are listed. No source opened here reports the state of implementation in any province or territory.
• What the full committee report contains. The recommendation and the tabling date come from the cover page and from a secondary source. The full report was received as a PDF that could not be converted to text, so its reasoning is not represented here.
• Whether the exclusion is compatible with the Charter. That is the question in the pending litigation, and no source opened here reports a ruling.

See the evidence

No primary federal statute or committee report was read in full. The parliamentary pages for both committee reports were opened and carry the tabling dates and the recommendation; the report of the 45th Parliament exists here as a cover page plus a secondary account of its recommendation, because the full PDF could not be converted to text. The four federal pages that would be primary for the statutory history and the 2024 death counts all returned HTTP 403 to automated requests and were not retrieved by any other route, so those facts rest on sources that cite them. The one primary document read directly is the provincial bill history page of the National Assembly of Quebec, and the population figures come directly from the statistical agency release. Where sources overlap they agree: the 2027-03-17 date appears in three, and the June 2026 recommendation appears in two with the same direction. Where the record is thin it is left thin rather than filled — the vote behind the recommendation, the government position after 2026-07-11, and provincial readiness are absent from everything opened here and are listed as such rather than inferred. This is a research-based definition, so observation_refs is empty and provenance_mode: press-derived.

People affected

Estimated range 32,400,834–41,417,056 As of 2026-04-01

Sensitivity The width of the interval is exactly the population of Quebec and reflects a legal fact rather than statistical uncertainty. The lower bound counts residents for whom the federal outcome would change what the criminal law permits, and the upper bound counts everyone living under the federal provision. Neither bound counts people who would request or receive medical assistance in dying on the basis of mental illness alone, and no source opened here gives a Canadian estimate of that number, so this count overstates the group whose own circumstances are at stake by a margin that cannot be quantified from the sources opened here. It includes minors and everyone who would not meet the other eligibility criteria. In the opposite direction the lower bound may understate, because the federal provision defines the criminal law under which practitioners in Quebec also work and because residents move between provinces. Both population figures carry an as-of date of 2026-04-01 and will drift with any later quarterly estimate.

Regional breakdown No source opened here gives a provincial or territorial breakdown of the people affected by the federal start date. The only sub-national figure available is the population of Quebec, and it is used here as a jurisdictional boundary term rather than as a regional allocation, because Quebec has legislated its own permanent exclusion. Distributing the national figure across the remaining provinces and territories would be a pro-rata split of a legal question rather than a measurement.
