Paying. Tap a contactless card or phone, or use a Presto card. One tap buys two hours of unlimited travel in any direction, including transfers and a return journey — an unusually generous rule.
Cash on streetcars and buses needs exact change and gives none.
Subway. Line 1 (Yonge–University) is a U running north from Union up both University and Yonge. Line 2 (Bloor–Danforth) crosses it east–west. They meet at Bloor–Yonge and St George. Line 4 is a short northern stub. Line 3 closed in 2023.
Streetcars. The largest network in North America, and how you reach much of what is interesting — 501 Queen, 504 King, 506 College, 510 Spadina. They run in traffic and are slow. Several run 24 hours.
Line 5 Eglinton has been under construction for over a decade with repeatedly delayed opening. Check whether it is running.
GO Transit is the regional network from Union Station — Niagara, Hamilton, Barrie — on separate fares.
The PATH is 30 kilometres of underground tunnels beneath downtown, essential in winter, confusing always, and largely closed at weekends.
The airport. The UP Express reaches Union in 25 minutes; bus 900 to Kipling plus subway costs one TTC fare.
Cycling. Bike Share Toronto, with separated lanes on Bloor, Danforth, Richmond and University, and the waterfront trail.
