My son is flying through Pearson on his way to Cancun on a Saturday afternoon this month with Air Canada (coming from Ottawa). The airline has given them a 1.5hr connection. I assume they don't have to do any customs clearance in Toronto. Is that going to be enough time to comfortably make the connection?
I usually allow myself 2-2.5 hours to connect in Toronto as I'm usually clearing customs to the US.
