Great Report! Enjoy your stay in YYZ
I too had a long wait for a gate at YYZ yesterday afternoon. I was on AC717 LGA-YYZ which arrived at about 16:45. We then had to wait about 20 minutes for our gate (We were 5 minutes early into YYZ). I did notice that gate 97 was blocked off and closed as they are working on the tarmac area around it.
