Legal Use of Cannabis in Ontario


  • In Ontario, the legal age for possessing and purchasing cannabis is 19 years or older. 
  • You can buy up to 30 grams of dried cannabis flower (or its equivalent) at a time.


Legal Consumption Age

The federal Cannabis Act sets the legal age of cannabis possession in Canada at 18 years but grants the authority for provinces and territories to raise the legal age. In Ontario, the legal age of cannabis possession and consumption is 19 years or older, which aligns with the province’s legal age for alcohol use.


Legal Forms of Purchasable Cannabis

The federal Cannabis Act legalizes fresh and dried cannabis, cannabis oil, plants and seeds for cultivation. On, you can buy dried cannabis, Topicals, seeds and cannabis oil, extracts (including vapes) and edibles.

The provincial legislation also maintains the federal legal limit of four plants per private residential dwelling (not per adult).

Laws Governing Driving Under the Influence of Cannabis

Both federal and provincial legislation set out key provisions related to drug-impaired driving offences and procedures. Police are now able to detect suspected drug-impaired driving and enforce strict offences related to drug-impaired driving.
