GTAA and CATSA is a joke.
I am 20 minute from YYZ and 1h40m from BUF. Most of my flights are US TPAC or TATL.
I can drive from my home, park, get to the gate faster going to BUF than YYZ. Not to mention it is cheaper. I just refuse to pay "airport improvement/service charge" to be frustrated by these jokers.
