Expiring Passports and applying for Immigration

you can apply for immigration; if you do not require a visa, you can apply for temporary residence at a Canadian port of entry. There is no rule that prevents you from entering if your passport isn't valid for at least six months; however, timing is critical because your status will be limited to the term of your passport at the most extreme.
