Toronto is served primarily by Toronto Pearson International (YYZ) and Billy Bishop Toronto City Airport (YTZ), with Pearson typically functioning as the major international hub and Billy Bishop catering to regional and some low-fare carriers. Pearson hosts a wide mix of full-service and budget airlines and can be perceived as mid-to-high price for transatlantic and long-haul routes, while Billy Bishop often offers cheaper short-haul connections to northeastern North America. Pearson sits about 22 km northwest of downtown — expect 25–45 minutes by UP Express train (around CAD 12–20) or 30–60 minutes by taxi/rideshare depending on traffic (CAD 40–70). Billy Bishop is on the Toronto Islands, roughly 2–5 km from the core; a short pedestrian tunnel or a ferry (5–10 minutes, small fee) connects it to the harbourfront, with quick taxi or rideshare rides available. Pros: Pearson provides extensive international connections and full passenger facilities; cons: it can be busy and transfers may take longer. Billy Bishop’s advantage is convenience for downtown access, though it has limited long-haul options and smaller terminal amenities.

San Francisco International Airport (SFO) is the region’s primary international hub, handling a mix of long-haul carriers, major U.S. network airlines and some premium transpacific services; it can be pricier on peak routes compared with secondary Bay Area airports. Located about 13 miles south of downtown San Francisco, travel typically takes 20–35 minutes by BART or 25–45 minutes by taxi/rideshare depending on traffic. BART fares are usually in the low-to-mid single digits for most central stations, while taxis and rideshares can vary substantially. Pros: extensive international connections, good ground transit links and full-service amenities. Cons: busy terminals, occasional delays and higher airport-area parking and dining costs.

The cost of a one-way flight from Toronto to San Francisco ranges from $223 (December 2025) to $319 (November 2025). On average, the ticket price is about $262–$563.
