What's Illegal inCanada?

The single thing worth knowing first: Cannabis is legal BUT crossing ANY border with it = federal crime. Zero tolerance. It is the kind of rule that looks minor at home and becomes a serious problem at the border or in public, which is exactly why it tops this page.

Within everyday items and devices, Canada treats Pepper spray, Stun gun, and Replica firearm as off-limits. Carrying or doing any of these can mean confiscation, fines, or detention depending on the case — and a foreign prescription, habit, or "I didn't know" rarely helps once you are stopped. Each entry below links to the official source it is checked against, with the verified ones marked.

Two things travelers regularly get wrong about Canada: Carrying any amount of cannabis across the US border is a federal crime under US law, even between two legal jurisdictions; and Bear spray is legal for wildlife but using it against people can be charged as a weapons offence. Assumptions like these are how otherwise careful visitors end up in trouble, so it is worth checking the specifics rather than guessing.

One important caveat: Cannabis is federally legal but provinces set their own rules on retail, public consumption, and possession limits. Laws and their enforcement can shift between regions and over time, so treat this page as a sourced starting point and confirm anything borderline against the official links before you rely on it.
