The short answer
For non-medical cannabis, the federal public possession limit is up to 30 grams of dried cannabis or its equivalent. The legal age is not the same everywhere: it is 18 in Alberta, 21 in Quebec, and 19 in the other provinces and territories listed by Health Canada.
Minimum age and public limit
Health Canada's jurisdiction directory lists these headline rules:
| Jurisdiction | Minimum legal age | Public possession limit |
|---|---|---|
| Alberta | 18 | 30 g dried or equivalent |
| Quebec | 21 | 30 g dried or equivalent |
| Other provinces and territories | 19 | 30 g dried or equivalent |
The federal limit is a dried-cannabis equivalent across product types. Check Health Canada's calculator for equivalent amounts; it is a convenience tool, not a substitute for provincial or territorial rules. Do not add unlike products without converting them.
Before purchase or travel
Provinces and territories set retail and distribution rules and can add restrictions on age, possession, public use and cultivation. Buy only through an authorized retailer in the province or territory. Do not assume one province's store, age or use rule applies at your destination. This summary covers the headline public limit, not home-storage limits, medical authorization or impaired driving.
