Flight from Chicago O'Hare Airport to Toronto Pearson Airport

Verified travelerFlew with Air Canada-Oct 2026

O'Hare is a big airport, so find some time to look at the layout befire arrival so you know roughly where you are and where you're going. Signage is great so it shouldn't be a great hassle.

NikhilFlew with Air Canada-Jul 2025

small flight, not much storage space as per the passengers. Try to get a booking which is Group 1 or 2 latest.
