Frequently Asked Questions
Can you bring weed across the Canada-US border if you have a medical card?
No. Transporting cannabis across the US-Canada international border in any form remains strictly illegal under both US federal law and Canadian statutes. Holding a medical card, physician prescription, or traveling between legal states and provinces does not provide an exemption and can trigger arrest.
How much cash can I carry between the US and Canada without declaring?
You can bring any amount of cash, but you must declare amounts of $10,000 or more (in USD when entering the US, or in Canadian dollars/equivalent when entering Canada). Failure to report is subject to immediate seizure and civil penalties.
