Beyond frustrating.
Incredibly long/slow lines at security/customs back to US for reasons passing understanding. No one seems to be in much of a hurry.
Uber picks people up at departures, btw, even though people arrive at arrivals.
Arrive a minimum of 3 hrs before even on a light travel day.
Also, the highways to the airport from the city are shut down, likewise for reasons passing understanding, especially considering there is no viable public transit to the airport.
Canada, I love you, but please get your air travel together.
