The rules in Manitoba
Filing deadline
2 years
Counted from when the injury was discovered. Start the claim within 2 years after the day the claim is discovered (Manitoba's Limitations Act in force since September 30, 2022).
Discovery rule
Applies
Yes, the Act is discovery-based.
Outer limit
15 years
Ultimate limitation period: no proceeding more than 15 years after the act or omission.
The Limitations Act, C.C.S.M. c. L150, s. 10
Damage caps
Non-pecuniary damages (pain, suffering, loss of enjoyment of life) are capped by the Supreme Court of Canada's 1978 trilogy (Andrews v. Grand & Toy Alberta, Thornton, Teno) at $100,000 in 1978 dollars, indexed to inflation: about $484,330 as of September 2026. Courts award the full cap only for the most catastrophic injuries.
There is no statutory cap on economic losses such as lost income or future care. The judge-made trilogy cap limits non-pecuniary damages nationally.
Children
Different clock
Limitation periods do not run while the claimant is a minor, unless a potential defendant serves a notice to proceed.
Affidavit of merit
Not required
No affidavit or certificate of merit is required to start a claim. In practice, expert reports on the standard of care and causation must be served under the court's rules.
Notice before suing
Not required
No pre-suit notice is required for claims against doctors, nurses or hospitals.
Shared fault
Pure comparative
Pure comparative fault: your award is reduced by your share of fault
Experts
Expert evidence
Expert evidence from a physician in the same field is needed to prove the standard of care and causation; reports must be served on the timelines in the provincial rules of court.
Fault is apportioned under The Tortfeasors and Contributory Negligence Act. Injuries before September 30, 2022 may fall under transition rules from the former Limitation of Actions Act. Most physicians in Canada are defended by the Canadian Medical Protective Association (CMPA), which contests most claims, so expert evidence and early legal advice matter.
When a Manitoba medical malpractice claim is discovered, you generally have two years after that day to start it under The Limitations Act, sections 6 and 7.
You shouldn't wait until you're certain. A Manitoba lawyer can check your deadline if you think treatment caused an injury, and review whether the medical care supports a claim. When you received treatment isn't necessarily the discovery date, and that date matters.
Use this guide for general information, not legal advice. If a child was injured or the injury happened before the current Act took effect, a Manitoba lawyer can explain how the limitation rules apply to the dates of treatment.
When the limitation clock starts
September 30, 2022 is when Manitoba's current Limitations Act took effect. Discovery starts the basic limitation period running. Tell your lawyer the two dates clearly: when you received treatment, then when you learned about the possible claim.
Write those dates down somewhere. Record what you were told, noting where you can find it (a chart entry or a later medical report, for instance). Don't decide this yourself: a recent explanation won't necessarily give you a fresh period to file the claim.
The injury
The clock usually starts on the date of the malpractice or injury.
Discovery
Yes, the Act is discovery-based.
2 years
Start the claim within 2 years after the day the claim is discovered (Manitoba's Limitations Act in force since September 30, 2022). (The Limitations Act, C.C.S.M. c. L150, ss. 6, 7)
15 years (outer limit)
Ultimate limitation period: no proceeding more than 15 years after the act or omission.
Children
Limitation periods do not run while the claimant is a minor, unless a potential defendant serves a notice to proceed.
The outer limit is a separate clock
Under Section 10 of The Limitations Act, the ultimate limitation period runs from the act or omission rather than discovery. Even if the patient learned about the possible error much later, you still need to check that outer boundary.
Both clocks appear in the timeline. Once you've discovered a claim, the outer limit isn't permission to wait before filing. Ask a lawyer to use the actual treatment history when checking each deadline.
Children and older injuries need a closer look
Unless a potential defendant serves a notice to proceed, limitation periods don't run while the claimant is a minor. Take any notice you've received to a Manitoba lawyer if your child was injured. You can't assume the clock remains paused.
If an injury happened before September 30, 2022, transition rules from the former Limitation of Actions Act may apply. Don't rely on the current discovery rule alone. Even if your concerns only arose recently, your lawyer needs the earlier treatment dates to assess those cases.
What compensation limits mean
Manitoba doesn't set a statutory cap for economic losses (including lost income or future care). Pain and suffering work differently. The non-pecuniary damages category covers loss of enjoyment of life as well as pain and suffering.
| Damages | Limit in Manitoba |
|---|---|
| Non-pecuniary (pain and suffering) | Non-pecuniary damages (pain, suffering, loss of enjoyment of life) are capped by the Supreme Court of Canada's 1978 trilogy (Andrews v. Grand & Toy Alberta, Thornton, Teno) at $100,000 in 1978 dollars, indexed to inflation: about $484,330 as of September 2026. Courts award the full cap only for the most catastrophic injuries. |
The Supreme Court of Canada's 1978 trilogy set the national ceiling for non-pecuniary damages, with Andrews v. Grand & Toy Alberta Ltd. among those cases. Inflation adjusts the ceiling. You can check: McKellar Structured Settlements publishes the indexed figures (and McCague Borlack LLP discusses the trilogy cap and indexation).
An award isn't usually at the ceiling. Only the most catastrophic injuries lead courts to award the full cap. Even though there's no statutory economic-loss cap, that doesn't tell you what your lost income or future care claim is worth.
A Manitoba lawyer should check the rules for an overall damages cap, as well as punitive damages. They should check wrongful-death limits, too. Don't mix those questions with the established distinction: economic losses aren't the same as capped non-pecuniary damages.
What a claim needs before and at filing
You can start a medical malpractice claim in Manitoba without an affidavit or certificate of merit. Claims against doctors or nurses don't require you to give pre-suit notice. Claims against hospitals follow that rule.
Your case still needs expert evidence. To address the standard of care and causation, you need a physician from the same field. The provincial rules of court set timelines for serving expert reports, and you must meet them.
| Requirement | The rule |
|---|---|
| Expert report before suit | No affidavit or certificate of merit is required to start a claim. In practice, expert reports on the standard of care and causation must be served under the court's rules. |
| Notice before suing | No pre-suit notice is required for claims against doctors, nurses or hospitals. |
| Expert evidence | Expert evidence from a physician in the same field is needed to prove the standard of care and causation; reports must be served on the timelines in the provincial rules of court. |
| Shared fault rule | Pure comparative fault |
Proving a claim takes more than starting it. What you must file with the claim is one question, but proving the case requires you to consider the evidence separately. Even without a filing certificate, you need a medical opinion that connects the care you received to the injury.
Ask the lawyer how they'll arrange a same-field physician's review when you meet for a consultation. Include the chart in your questions. Before the reviewer gives an opinion, ask whether the chart answers the medical questions or whether they need more records.
Shared fault can affect the claim
The Tortfeasors and Contributory Negligence Act governs how Manitoba divides fault. Because the rule is pure comparative fault, responsibility can be shared; it isn't an all-or-nothing question.
If the other side says you contributed to the injury, tell your lawyer what happened and what instructions you received. Ask how sharing fault could change your claim. Your Manitoba lawyer can explain the allegation without treating what the other side says as fact.
How a case usually moves forward
The Canadian Medical Protective Association (CMPA), which defends most physicians in Canada, contests most claims. That's why it helps to speak with a lawyer early and get expert evidence. That doesn't tell you how your own case will turn out.
Review the dates with a lawyer
Write down your treatment date, then when you learned you might have a claim. Before you decide to wait, ask your lawyer to check discovery and the outer limit, including any transition rules or rules for a minor.
Organize the medical records
Take any chart or related reports you already have to your lawyer, noting gaps (missing delivery notes, for example). Don't use memory to fill in missing medical entries.
Assess the medical evidence
You'll need a same-field physician's evidence to show the standard of care and causation. Ask your lawyer how they'll arrange the review, including what questions the physician will need to answer.
Start the claim and prepare the reports
If you go ahead with the claim, your lawyer can prepare the statement of claim and explain how filing works. You don't need a merit affidavit to start in Manitoba. You'll still have to serve expert reports under the provincial court rules.
Work toward settlement or trial
Talk about settlement with your lawyer as the case develops; if it remains unresolved, ask whether the evidence supports taking it toward trial. You aren't promised compensation. Ask them to assess the medical evidence frankly, along with the defence's position.
What you can do now
Whatever you've got, start there. When a conversation is upsetting, you can use a short written account of your concerns instead of recalling every detail.
- Include dates when writing. Your account of the treatment shouldn't mix in things you learned later. If you're unsure of a date, say so beside it.
- Gather the documents already available. Bring the chart or medical reports you have, adding any notice to proceed that involves a child.
- What's changed in your daily life? Once you've explained lost income and care needs, ask your lawyer what documents will help them work out your losses.
- Your deadline comes first. Your lawyer needs to know straight away if treatment happened before the current Act took effect or many years ago.
You don't need to work out the law first. Once you've explained what concerns you about the treatment and what changed afterward, your lawyer can assess the legal questions, including whether a same-field physician's evidence supports going ahead.
