Although cannabis is legal within Canada under the Cannabis Act (S.C. 2018, c. 16), Canada remains a signatory to the 1961 UN Single Convention on Narcotic Drugs. This treaty obligates Canada to restrict international cannabis trade to medical and scientific purposes only — and only with licensed exporters and eligible importing countries.
Legal Framework
Key statutes governing international cannabis trade in Canada
Cannabis Act (S.C. 2018, c. 16)
Section 62 of the Cannabis Act specifically governs import and export. It prohibits import/export of cannabis except under an authorization (licence) granted by the Minister of Health, and only for medical or scientific purposes.
Cannabis Regulations (SOR/2018-144)
Part 14 of the Cannabis Regulations sets out the requirements for import and export licences. Applicants must demonstrate they are importing/exporting cannabis for legitimate medical or scientific purposes and that the destination country authorizes the importation.
1961 UN Single Convention on Narcotic Drugs
Canada is bound by this treaty as a signatory. Articles 28–32 specifically address cannabis. Trade is only permitted between countries that have mutually agreed to import/export for medical purposes. Both countries must have appropriate national licensing systems.
Customs Act & CBSA
The Canada Border Services Agency enforces the Cannabis Act at ports of entry. Unlicensed import/export attempts result in seizure and referral to the RCMP or provincial police. Criminal charges may be laid under the Cannabis Act.

⚡ Critical Points to Watch — Canada
- Domestic legality does NOT mean trade is free. Canada's federal legalization applies only within Canada. International trade requires separate licensing from Health Canada under the Cannabis Regulations, Part 14.
- No commercial recreational export exists. Even though adult-use cannabis is legal domestically, there is NO legal pathway to export recreational cannabis from Canada to any country.
- Receiving country authorization is mandatory. Canada will not issue an export authorization unless the receiving country has formally authorized the import and can demonstrate a licensed medical/scientific purpose.
- Crossing the US-Canada border with cannabis is illegal in both directions, regardless of state/provincial legality on either side. CBP and CBSA both enforce federal cannabis prohibition at the border.
- Personal use amounts are still prohibited cross-border. Even small personal amounts declared at the border will be seized and may result in arrest.
- GMP certification is critical for export. Most eligible importing countries require pharmaceutical-grade GMP certification for medical cannabis — Canadian producers without EU-GMP or equivalent certification will face market access barriers.
