So a US patent is NOT enforceable in Canada.
For example... you have a US patent for a new gun, but no other patents in any other country. Then some enterprising person can make an exact copy of that gun and sell it, so long as that person doesn't make it or sell it in the US. Oh, this copy gun can't be imported into the US either.
