That's not a close call. They don't start handing out drinks if they're just about to leave.
Will remember my passport...birth certificate? Do I need that?
You don't need your birth certificate if you have your passport.
By the way, on the return flight you will pre-clear U.S. Customs in Montreal. So if you had a 50 minute connection in Detroit on the return that would also be no problem.
