What is the Toronto Subway System?
The Toronto Transit Commission (TTC) operates one of Canada’s busiest and most important urban transit networks. At the heart of this system is the Toronto Subway, a reliable, fast, and affordable way to navigate the city. Whether you’re a daily commuter, a student, or a first-time visitor, this Toronto subway guide provides a complete overview of the TTC transit system—covering routes, costs, accessibility, and travel tips.
Overview of the TTC Subway System: The Toronto Subway consists of four main lines:
- Line 1 (Yonge–University) – The city’s busiest line, running in a U-shaped loop from Vaughan in the north, through downtown, and back up to Finch Station.
- Line 2 (Bloor–Danforth) – Runs east–west from Kipling in the west to Kennedy in the east.
- Line 3 (Scarborough RT) – A short, elevated line linking Kennedy Station to Scarborough Centre (currently being replaced by bus service as part of the Scarborough Subway Extension project).
- Line 4 (Sheppard) – A short east–west line in North York connecting Sheppard–Yonge to Don Mills.
The TTC network spans 75 subway stations, with connections to hundreds of TTC bus and streetcar routes, making it easy to travel across the city without a car.
Efficiency and Frequency
Toronto’s subway system is known for its consistent schedules. During peak hours, trains run every 2–3 minutes, and off-peak service averages 4–5 minutes. Most stations open around 6 a.m. (8 a.m. on Sundays) and close shortly after 1:30 a.m., with Blue Night buses covering key routes after hours.
The system is designed for quick travel across long distances, avoiding Toronto’s notorious traffic congestion.
Fares and Payment Options
The TTC offers a flat fare system, meaning you can travel anywhere on the network for one price. As of 2025, adult fares are $3.35 when using a PRESTO card, with discounted rates for youth, seniors, and monthly pass holders. Transfers between subway, bus, and streetcar routes are included within a two-hour window.
