Hi there, Quick question -- I need to visit a friend in Canada, briefly (one day), driving from Detroit. Situation is --- I am a green card holder (it does not expire for a while), but my foreign national passport (Russian) has expired in 2006, and I never renewed it. Are a green card and a US driver's license enough to enter Canada? I will bring my passport with me, but the fact that it's expired -- would that be an issue? Thanks all!
