A: 20 yrs from filing date. The US Patent is not enforceable in Canada, but the application can be accepted in Canada for a national stage filing. To discuss further, contact our firm:

A: To augment the earlier answer, a US patent would apply to something made in Canada and then shipped into the US. US patent would cover something made in the US and shipped into Canada.

US patent would NOT cover something used in Canada that was made in Canada or a country other than US if the product never stayed in the US. (There is an exception for ships (so that they can sail from place to place without worrying about local patents) but that is probably not your concern).
