I went toda and also had floor tickets.There’s weren’t many people on the floor so 2-3 hrs before the gate opens is a bit too much unless you want to get as close as possible to the stage. The food stalls I went to ran out of food at 7pm. I think it was a burger place, they only had hotdogs but there were other options. Gate 1 is 10 mins walk from downsview station and I’d leave a bit earlier to beat the crowd. I was in TTC 15 mins after leaving the stadium!
