I arrived from Paris yesterday to find the T1 immigration hall packed with more people than I’ve ever seen. The Canada/US side had a huge backup of people who had checked in at a kiosk and were waiting to get out. They formed a line in the kiosk area that basically took up all remaining space as it wove around. I didn’t time how long it took to clear immigration, but my guess is that this was the worst I’ve ever seen at YYZ, and I travel a lot. Funnily enough, my daughter said the same thing about her arrival from DC on Tuesday. On the plus side, our luggage had arrived at the carousel and been unloaded by the time we made it to baggage claim.
