If you're flying in on an international flight, you'll have to claim your luggage to clear customs. Add to this the large size of the airport, and you should make sure you've got plenty of time.
The lineup for Tim's in T1 USA terminal can be crazy but the burger place right beside it serves a better breakfast and has coffee! One less airportline to wait in.
Much improved in recent years. WiFi works, power widely available, iPads for food order/info/web widely available, a selection of food, water fountains.
delayed flight? - terminal 1 (to has premium lounge past gate F55. 50$ for two hours, unlimited food and drinks (non top shelf drinks, 5-10$ for top shelf). Best place relax than most restaurants.
Air Canada and all other Star Alliance airlines that serve Toronto Pearson operate out of Terminal 1. The terminal is also used by non-alliance airlines Etihad Airways and Emirates.
The Prayer room(inter faith room) is closer to the domestic arrivals.Prayer mats & Qibla direction is clearly marked.Jum'ah prayers also conducted on Fridays.
Too many people write crap because of some attitude towards airlines. I'm a frequent flyer and this is one of the best terminals & airports in the continent!!
Be ready for a long walk. The temporary terminal extension for USA flights takes just over seven minutes. Having a trolly bag for your trip through this teminal wouldn't be a bad idea.
This place is the twilight zone! Avoid it at all costs. Never get here early for a flight. They'll just make you wait for hours while all the late people cut ahead of you. What a shit hole!
Air Canada representatives are extremely rude and condescending towards customers. Especially united customers. To void fees for everything you have to talk to united customer service.
