Oh man. This airport was terrible. Perhaps it was because we were flying WestJet and perhaps because of renovations, but the terminal was a mess. Gate A6 is wayyyyy too small for all the flights going out of the 4 gates they have there. Many bathrooms are out of service due to renovations.
It was nice that we were able to go through US customs there instead of having to wait until arrival in the US.
One plus in both Toronto and Calgary airports is that there aren't armrests across the chairs so you can lay down if there's space.
