Prohibited Items Entering Canada

When you enter Canada by land, the Canada Border Services Agency (CBSA) decides what may cross based on Canadian law—not US state law or what you “usually get away with.” This page highlights high-risk categories travellers misunderstand. It does not replace the official lists; use the links below for authoritative wording.

Weapons And Replica Firearms

Many items that are legal in parts of the United States are restricted or prohibited in Canada, including certain knives, pepper spray marketed for use on people, and firearms without the correct import paperwork. Replica firearms and some accessories can also be seized.

Cannabis

Even if cannabis is legal where you bought it in the US, bringing it into Canada without meeting import rules can still be an offence. Do not assume a sealed retail package is automatically fine. When in doubt, read CBSA’s current guidance rather than social media posts.

Food, Plants, Soil, And Wood

The Canadian Food Inspection Agency (CFIA) sets many rules that CBSA enforces at the border. Fresh produce, meat, eggs, homemade preserves, houseplants, firewood, and soil on boots or camping gear are common trouble spots. Declare everything on your declaration card or at the kiosk—“I did not know” is not a reliable defence.

Medications

Personal prescriptions in reasonable quantities may be allowed with conditions; narcotics, cannabis products without authorization, and bulk supplies can be refused or seized. Keep medications in original packaging with pharmacy labels when possible.

Currency And Monetary Instruments

If you arrive with CAN $10,000 or more (or foreign equivalent) in cash or certain monetary instruments, you must report it. Failure to report can lead to fines or seizure.

Alcohol And Tobacco

Personal exemptions depend on how long you were away and whether you meet age rules by province. Exceeding exemption limits means duties and taxes, and some goods may be refused if you cannot show lawful purchase.
