i plan on travelling to our brothers up north, Canada around the end of August. however, my passport expired 4 months ago. i have been hearing a lot of differing opinions on this: some say i dont need a passport to get into Canada at all even if i'm taking a flight. anyway, i plan on going to Montreal with some friends for 3 or 4 days. any tips? anyone been to montreal? is it true the drinking age is 18? gambling age is 18? night life is insane?
