I love Montreal but it's ridiculous that you cannot pay for transit directly by tapping a credit card or Apple/Google Pay. I was there a few weeks ago and we caught a exo train into downtown from one of the suburbs and almost missed our train because the process of buying a daily ticket was so slow. It was almost at the point that I was trying to tell my travel companion to just get on the train and take the chances with whether or not anyone checked our tickets.
