How much do Toronto to Chicago flights cost?
One-way economy fares between Toronto and Chicago usually fall between C$130 and C$320, with the cheapest seats on quiet mid-week dates booked in advance. Business demand pushes fares up on Monday mornings and Friday afternoons. As with most cross-border routes, the lowest fares appear about 4–8 weeks before departure.
When is the cheapest time to fly Toronto to Chicago?
Toronto–Chicago is a short, business-heavy route of under an hour and a half in the air, so the cheapest fares hinge on timing rather than season. Midday, evening and weekend departures beat the pricey weekday commuter peaks. Demand rises modestly in summer and around the winter holidays, but with frequent service there’s rarely a need to book far ahead — two to four weeks usually suffices. Major conventions in Chicago can spike prices on specific dates, so check the city’s event calendar if your dates are movable.
Tips for finding a cheaper Toronto to Chicago fare
Air Canada and United (via its Chicago hub) offer the most frequency, with connections available on other carriers. Because O’Hare (ORD) is a major United and American hub, a Toronto–Chicago leg often bundles cheaply with onward US flights, so check a through-fare if Chicago isn’t your final stop. Toronto Pearson (YYZ) has US pre-clearance, letting you arrive at O’Hare as a domestic passenger — a real time-saver given ORD’s size. As with all US routes, a passport and, where applicable, an ESTA are required.
