The rules in Alberta
Filing deadline
2 years
Counted from when the injury was discovered. Start the claim within 2 years after you first knew or ought to have known of the injury, that it was attributable to the defendant's conduct, and that it warranted a lawsuit, or within 10 years after the claim arose, whichever expires first.
Discovery rule
Applies
Yes, inside the 10-year ultimate period.
Outer limit
10 years
Ultimate limitation period of 10 years after the claim arose.
Limitations Act, R.S.A. 2000, c. L-12, s. 3(1)(b)
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 are suspended while the claimant is a minor, unless a potential defendant serves a notice to proceed on the guardian and the Public Trustee, which starts the clock running.
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 Contributory Negligence Act, R.S.A. 2000, c. C-27. Alberta's 10-year ultimate period is shorter than the 15 years used in most other provinces. 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.
