Open ProvincesCannabis rules in Alberta: legal age, where to buy and where to use
The legal age for cannabis in Alberta, where you can legally buy it and the main rules on possession and use, from the official pages.
Legal age, where to buy and where to use
Age 18 (the lowest in Canada). Buy only from licensed cannabis retailers or legal websites; minors may not enter cannabis stores, even with an adult, and staff must check ID for buyers who look under 25. Possession limit is 30 grams in public. Older 2018 pages say online sales are only through the provincial site: that is outdated.
Federal law sets the 30-gram public possession limit; provinces set the age, sales model and where you may use it. Never drive after using cannabis, and never carry it across the border. Rules, fees and programs change and were read on 2026-11-14: confirm with the official source. General information, not legal advice. Quebec follows its own rules: see atlasquebec.ca.
