Cannabis and the Canadian Border: Why You Cannot Cross With It
Quick answerBringing cannabis in any form, including THC or CBD oils, into or out of Canada is illegal unless you have a permit or exemption from Health Canada. This applies even if cannabis is legal where you bought it. Drug smuggling is a criminal offence.
What the CBSA says
The CBSA border checklist (updated March 11, 2026) says that bringing cannabis in any form is illegal, including oils containing THC or CBD, unless you have a permit or exemption from Health Canada. It also warns that drug smuggling is a criminal offence and that travellers should never carry items for others.
What to do
- Do not carry cannabis products across the border, whether you buy them in Canada or abroad.
- Do not carry anything for another person.
- If you believe you need a permit or exemption, contact Health Canada before you travel. This site cannot tell you whether you qualify.

FAQ
Can I bring CBD oil?
Not if it is cannabis-derived and you lack a permit or exemption. The CBSA checklist includes THC and CBD oils.
I bought cannabis legally in a US state. Can I bring it?
No. Legal purchase does not change the rule that bringing cannabis across the border is illegal without a Health Canada permit or exemption.
Do I declare it?
Declaring does not make it legal to bring. Do not carry it.
