I think Terminal 1 at the Toronto Pearson International Airport should be for US/Canada destinations and Terminal 3 should be for Southern and International Flights. I have been working on this pilot project to pitch in this idea for the airport to make things more efficient and more practical in travel and to keep things organized. Especially for the Canadian and USA Travel out from the airport. Hopefully, this can work out. It will be a great step toward the right direction if this pans out.
