Cannabis at the Canada Border: CBSA Rules for Entry and Exit
The short answer: do not carry cannabis across the border
Canada Border Services Agency (CBSA) says transporting cannabis across Canada's border in any form--including products containing THC or CBD--without a Health Canada permit or exemption is a serious criminal offence. The rule applies regardless of how much cannabis you carry, whether you have medical documentation, or whether cannabis is legal at your origin or destination. Keep cannabis in Canada. Do not pack it for a U.S. crossing.

Entering Canada: declaration does not make it permitted
If you enter Canada with cannabis, CBSA says you must declare it. Declaration does not turn an otherwise prohibited import into an authorized one; undeclared cannabis can also lead to arrest and prosecution. Do not treat this page as advice to bring cannabis and declare it.
Leaving Canada: destination legality does not change the rule
CBSA also prohibits taking cannabis out of Canada, including to a place where adult-use possession is legal. CBSA describes limited permit or exemption pathways, but this page does not determine who qualifies. A Canadian permit does not establish permission to import cannabis into the United States; current U.S. federal/border requirements need a separate official check. The 2026 U.S. rescheduling of specified FDA-approved and qualifying state-licensed medical products is not a cross-border travel authorization. For a separate domestic-air question, see flying with cannabis inside Canada. Domestic rules do not authorize a border crossing.
Quick FAQ
Can I take a small amount across the U.S.-Canada border?
No. CBSA says the prohibition applies regardless of amount unless Health Canada authorizes a permit or exemption. This does not determine U.S. import permission.
Does a medical document let me cross with cannabis?
No. CBSA says medical documentation alone does not change Canada's border prohibition.
What if I am entering Canada and declare it?
CBSA says cannabis must be declared when entering, but declaration does not itself authorize import. Check Health Canada's permit rules before travel; do not assume eligibility.
