Is Weed Legal in Canada?

Canada legalized non-medical cannabis on October 17, 2018, when the Cannabis Act (Bill C-45, S.C. 2018, c. 16) came into force. Adults can legally possess up to 30 grams of dried cannabis (or equivalent) in public, share up to 30 grams with other adults, buy from provincially authorized retailers, and grow up to four plants per household for personal use. Section 8 of the Act sets the possession cap; Section 12 covers home cultivation. The minimum age is 18 in Alberta and Quebec, 19 in most other provinces, and 21 in Quebec for anyone wanting to purchase from the SQDC after the 2020 amendment.

Health Canada licenses producers and sets product standards under the Cannabis Regulations (SOR/2018-144), while provinces and territories run their own distribution and retail models — the Ontario Cannabis Store (OCS) wholesales to private stores in Ontario, the SQDC operates a government monopoly in Quebec, BC Cannabis Stores (BCCS) handles British Columbia, and the AGLC oversees Alberta's private retail network. Edibles, extracts, and topicals became legal one year later under the October 17, 2019 amendments (Cannabis 2.0), with a 10 mg THC cap per edible package and a 1,000 mg cap per extract container. Driving with a blood-THC concentration of 2 ng/mL or more carries a fine starting at CAD $1,000; 5 ng/mL or more is a hybrid criminal offence under Section 320.14 of the Criminal Code.
