Flight Time from Chicago (ORD) to Toronto (YYZ)

The 701 km between ORD and YYZ converts to 1.49 hours of flying under the 850 km/h + 40 min model. Each stopover adds ground dwell at the hub, so the totals model out to about 4.5 hours for one stop and 8.5 for two.

At 701 km this is a short sector; check rail and coach timetables for the same city pair before defaulting to a connecting flight, because the ground alternatives can win door to door. The clock moves 1 h forward (UTC−6 → UTC−5), so a morning departure can land well into the local evening.

Montreal (YUL) is the nearest alternative endpoint, 504 km from Toronto — close enough that some fares from ORD price it as the same destination. From ORD, reaching YUL instead takes about 1.3 h — less airborne time than the 1.49 h non-stop, and the surface leg into Toronto still has to be won back.

Companion flight-time pages exist for 3 of these alternatives (YUL first among them) — see Related calculators. Ground transfer from the alternative airport back into Toronto is the catch for arrivals off the ORD service: the 504 km back-offset is time you must win back in fare savings.

A 10:00 departure works out to roughly 12:29 on the clock in Toronto — the 1.49 h airborne leg plus the UTC−6 → UTC−5 shift. Hotel, meal and transit averages put a Toronto day at $230 against $230 in Chicago — worth weighing against any fare premium for better flight times.

A $0 per-day gap favors staying longer in Toronto and moving on from Chicago quickly. The modest 1-hour eastbound shift keeps the Chicago–Toronto trip easy to absorb.
