Travel Essentials
YYZ: EDT · SFO: PDT
When it's 6:00 PM in Toronto, it's 3:00 PM in San Francisco.
Canadian citizens do not need a visa or ESTA to enter the United States for tourism or business stays up to 6 months. A valid Canadian passport is required for air travel. Land and sea crossings also accept a NEXUS card, enhanced driver's license, or FAST card. At the border, officers determine the length of stay and may ask for proof of ties to Canada and a return plan.
The UP Express train runs from Union Station (downtown Toronto) to Terminal 1 in 25 minutes (CAD $12.35). Trains depart every 15 minutes during peak hours, every 30 minutes off-peak and overnight. Highway 427 and the 401 are heavily congested during rush hours.
Taxis and ride-hail from downtown cost CAD $50–70 and take 25–60 minutes depending on traffic. MiWay and Brampton Transit buses serve the airport from the western suburbs. Long-term parking is available in the Viscount Road lots with free shuttle service.
BART from SFO station (free AirTrain from any terminal to the station) to downtown San Francisco takes 30–40 minutes ($10.45 to Embarcadero). Traffic on 101 can make taxis and ride-hails much slower during peak hours; BART skips all of that. BART also reaches Oakland, Berkeley, and Millbrae for Caltrain connections.Ride-hails from SFO use a dedicated garage pickup area; follow signs. Taxis are metered; downtown SF costs $40–60. Caltrain to the Peninsula (Mountain View, Palo Alto, San Jose) requires taking BART to Millbrae station for the transfer. Rental cars are at a consolidated facility accessible by AirTrain.
Coastal fog dominates the climate pattern. The thick marine layer ("Karl the Fog") rolls into SFO from the Pacific regularly in summer (June–September), causing significant low-visibility delays even on days that appear sunny inland. Morning fog burns off by afternoon most days, but persistent IFR conditions can last all day. This is the primary flight disruption risk at SFO.
Temperatures are mild year-round (10–20°C) with little seasonal variation. Winters bring rain (December–March) and occasional atmospheric river events that cause brief but intense flooding on the 101. Summers are cool. Pack a light jacket year-round. Wind off the bay affects small aircraft approach paths.
