Flying SFO → YYZ takes about 4.95 hours (4 h 57 min) non-stop across the 3,644 km (2,264 mi) great-circle track. Below you'll find the clock-shift detail (UTC−8 → UTC−5), alternative arrival airports near Toronto and the stopover math for the SFO–YYZ sector.
San Francisco–Toronto flight times at each stopover level
| Measure | Value |
|---|---|
| Airport pair | San Francisco (SFO) → Toronto (YYZ) |
| Great-circle distance | 3,644 km (2,264 mi) |
| Non-stop flight time | 4.95 h (4 h 57 min) — 850 km/h + 40 min taxi model |
| One-stop total (est.) | ≈ 8.4 h (8 h 24 min) |
| Two-stop total (est.) | ≈ 13.4 h (13 h 24 min) |
| Time-zone shift | 3 h ahead (UTC−8 → UTC−5) |
Estimates use the site-wide 850 km/h cruise + 40-minute taxi model; real block times drift with winds and routing.

Airlines planning the SFO → YYZ leg start from the same arithmetic this page uses: 3,644 km ÷ 850 km/h, then the 40-minute airport allowance. Each stopover adds ground dwell at the hub, so the totals model out to about 8.4 hours for one stop and 13.4 for two.
At 3,644 km the sector sits in the everyday long-haul band: a non-stop is the benchmark, and connections only make sense when the fare saving clears a couple of hundred dollars. The clock moves 3 h forward (UTC−8 → UTC−5), so a morning departure can land well into the local evening.
If YYZ doesn't suit: the neighbors
| Alternative | Distance to Toronto | Flight time from SFO |
|---|---|---|
| Montreal (YUL) | 504 km | 1.3 h |
| New York (JFK) | 550 km | 1.3 h |
| Washington D.C. (IAD) | 563 km | 1.3 h |
| Boston (BOS) | 692 km | 1.5 h |
Fewer than two fields sit within 300 km of Toronto, so the radius was widened to 700 km.

If fares into YYZ spike, the airports tabulated below are the first places to check; each row shows the distance back to Toronto and the flight time from San Francisco. From SFO, reaching YUL instead takes about 1.3 h — less airborne time than the 4.95 h non-stop, and the surface leg into Toronto still has to be won back.
Where a matching calculator page exists (SFO → YUL, SFO → IAD among them) the links are in the Related list below. Ground transfer from the alternative airport back into Toronto is the catch for arrivals off the SFO service: the 504 km back-offset is time you must win back in fare savings.
Arrival clock and ground costs
Put a departure hour on the math: wheels-up at 10:00 from SFO puts you on the ground at YYZ around 17:57 local time, once the 3-hour gain is applied. Daily spend shifts at landing: $230 in Toronto against $311 at home in San Francisco, using the dataset's mid-range figures.
On those numbers Toronto is the cheaper place to linger — the gap is $81 per day, which over a week funds a second flight. The modest 3-hour eastbound shift keeps the San Francisco–Toronto trip easy to absorb.
