Can I travel to Canada from the United States with an expired United?
It's up to the Canadian immigration officer. Canada doesn't actually require a US citizen to enter with a US passport, just that they need to have sufficient proof of US citizenship. Although the best way to do that is with a valid US passport, an expired US passport is still pretty good proof of citizenship. Birth certificate plus photo ID is also good proof. Note if you are flying to Canada the airline might not let you board in the first place.
