Tips for this route

  • American, Delta, United and Southwest all fly SFO to YYZ nonstop, so compare the total with bags before picking the lowest base fare: the difference between a basic and a standard economy ticket is often less than one checked bag each way.
  • January 2027 is the cheapest month to fly over the next six months, with round trips from $189; September 2026 is the most expensive at $250 and up, a difference of $61 per traveler.
  • Departing on a Wednesday averages 20% less than a Sunday on this route. If your dates are flexible, shift the outbound by a day or two and check the calendar view before you book.
  • Book 6 to 12 weeks ahead; fares climb in the last three weeks and around holidays.
  • Toronto is 3 hours ahead of San Francisco. Expect to lose 3 hours on the clock heading east, so an overnight or late-afternoon departure tends to arrive at a more usable hour.

Destination guide

Toronto: North America's most multicultural city

Toronto is a short hop from the Northeast and Midwest, with Air Canada, WestJet and every US legacy carrier competing on fares. The CN Tower, the Islands, Kensington Market and neighborhoods from Greektown to Little Italy make it a rich city break.

Best time to visit: May–September is warm with festivals nearly every weekend (TIFF in September). Late spring and early fall have the best value; winter is cold but hotels are cheap.
