What's Legal

Legal Use of Cannabis in Ontario

What you need to know before your start shopping.


  • In Ontario, the legal age for possessing and purchasing cannabis is 19 years or older.
  • OCS is the only legal retailer of recreational cannabis.
  • You can buy up to 30 grams of dried cannabis flower (or its equivalent in cannabis oil) 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 Purchase Outlets

In Ontario, OCS is the only retailer of legal recreational cannabis. Cannabis products are only available online at Once a legislative framework is in place, anticipated to occur in April 2019, strictly regulated private retail stores will also be authorized by the province to sell recreational cannabis.

Legal medical cannabis purchases must be made through Health Canada licensed sellers. OCS cannot give medical advice or fill medical prescriptions. Talk to your doctor for details about the medical use of cannabis.


Legal Forms of Purchasable Cannabis

The federal Cannabis Act legalizes fresh and dried cannabis, cannabis oil, and plants and seeds for cultivation. On, you can buy dried cannabis and cannabis oil. Seeds will be available at a later date. Edible products and concentrates are not legal for purchase or available for sale at this time.


Legal Allowable Quantity

Federal legislation defines a maximum public possession limit of up to 30 grams of dried legal cannabis at any time or its equivalency in oil. As a result, limits any one transaction to a maximum of 30 grams of dried cannabis or its equivalent in other forms. This is easy to track as you shop online: The total number of grams you’ve accumulated is displayed as you put items in your bag.

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