Will Canada stamp your passport if you enter by land from the USA?
Not normally. You can request it, but they dont like such requests and it can result in getting some serious questioning as punishment. They can carefully examine every page of your passport, question you about any trip youve ever taken, they could even hold you there indefinitely for a week without charges while they seek information on you from the American government. That sort of thing is more likely encountered in the other direction however; Canadians are generally pretty mellow, but my advice is to NOT seek extra stamps for your passport by doing this anywhere. Always be respectful when crossing borders, dont ask for extra services or favors, and when they say you can go, GO.
