Flights from Chicago to Toronto
The 702-kilometre hop between Chicago O'Hare and Toronto Pearson is one of North America's busiest transborder corridors, covering the short-haul distance in a typical block time of just under an hour and twenty minutes. Air Canada and United Airlines dominate with the highest frequencies, operating regional jets alongside narrowbodies such as the Airbus A320 family, while American, WestJet, Iberia, and Etihad round out the carrier mix — the latter two primarily as codeshare partners feeding their respective long-haul networks. A practical note worth flagging: flights arrive into Pearson's Terminal 1, where the CBSA pre-clearance arrangement does not apply on this direction, so budget extra time for Canadian customs on arrival. Fares tend to soften in late January and February outside holiday windows, and mid-week departures consistently yield lower yields than Friday or Sunday travel when business traffic spikes.
