The Toronto subway helps people travel around the city.
It is a large rail network. It has many different lines. The TTC runs the whole system.
The first line opened in 1954. It was called the Yonge subway. It ran under Yonge Street.
Today, it is part of Line 1. Line 1 is the longest and busiest line. It is shaped like the letter U. It goes from Union Station to Vaughan.
There are other lines too. Line 2 runs east and west. Line 4 is the shortest line. It stays fully underground.
Line 5 is a light rail line. Light rail uses tracks on the street. Line 5 has some parts underground. Other parts run on the road.
Line 6 is also a light rail line. It runs on the surface.
New lines are coming soon. The Ontario Line is being built. It will go under the city. It will help people move through the center. The system is growing every year.
The Toronto subway is a huge rail network in Ontario, Canada.
It helps people move quickly through Toronto and the city of Vaughan. The Toronto Transit Commission, or TTC, runs the whole system. It is the busiest rapid transit system in Canada. On a typical weekday, it carries about 1.2 million riders.
The network includes 109 stations for people to use. There are many different lines that connect various parts of the region.
Each line has a specific name and a color. The colors help people find their way on maps. Line 1 Yonge–University is the longest and busiest line. It has a U-shape that connects Union Station to Vaughan Metropolitan Centre.
Line 2 Bloor–Danforth runs east and west through the city. Line 4 Sheppard is the shortest line in the system.
It is also the only line that stays completely underground. Line 5 Eglinton and Line 6 Finch West use light rail technology. These lines use tracks that sometimes run on the surface of the road.
History shows how the system grew over many years. The first line opened on March 30, 1954.
People called it the Yonge subway back then. It ran from Union Station to Eglinton Avenue with 12 stations. In 1963, the University subway opened as an extension. Line 2 Bloor–Danforth opened later in 1966.
The system keeps growing through many different extensions and new projects.
Many important dates and numbers define this transit system. Line 4 Sheppard opened in 2002 under Sheppard Avenue East.
Line 6 Finch West opened on December 7, 2025. Line 5 Eglinton opened on February 8, 2026, for about $12 billion.
A former line called Line 3 Scarborough closed in 2023. This happened after a derailment on July 24, 2023. Now, workers are building the Ontario Line. This new underground line will cost between $17 and $19 billion.
Understanding the subway is like understanding the veins of a city.
Just as your body uses paths to move blood, the city uses these rails to move people. The tracks act like roads that carry trains instead of cars. Some trains run deep under the ground in tunnels.
Other trains run in the middle of busy streets. This variety helps the city stay connected and moving every single day.
The Toronto subway is a massive rapid transit network in Ontario, Canada.
It serves the city of Toronto and the neighboring city of Vaughan. The system is operated by the Toronto Transit Commission, also known as the TTC. This agency is part of the City of Toronto. The network is the busiest rapid transit system in Canada. On a typical weekday, it carries about 1.2 million riders. It includes 109 stations across various routes.
The system uses different types of rail technology to move people. Some lines use heavy-rail subway trains that run in deep tunnels. Others use light rail technology, which can run on the surface. For example, Line 5 Eglinton is a light rail line. It has 25 stopping points in total. Fifteen of these are underground stations. The other ten are at-grade stops located in the road's median.
This mix of underground and surface travel helps the system cover more ground.
Line 1 Yonge–University is the longest and busiest line in the system. It has a U-shaped route. Its southern end is at Union Station in downtown Toronto. The two northern terminals are at Finch and Vaughan Metropolitan Centre.
This line has grown significantly since it first opened. In 1954, it was much shorter. It has grown to be over five times its original length. A new extension to Richmond Hill is also planned for the 2030s.
Line 2 Bloor–Danforth is another major part of the network. It opened in 1966 and runs east and west. It follows the paths of Bloor Street and Danforth Avenue. The line runs between Kipling station in Etobicoke and Kennedy station in Scarborough.
Construction has begun on a three-stop extension for this line. This extension will go from Kennedy station toward Sheppard Avenue and McCowan. This project is also expected to open in the 2030s.
There are also shorter or more specialized lines in the system. Line 4 Sheppard opened in 2002. It runs under Sheppard Avenue East. It is the shortest rapid transit line in Toronto. It is also the only line that is fully underground without open sections.
Line 6 Finch West opened on December 7, 2025. It runs westward at-grade in the median of Finch Avenue. It has 18 stops between Finch West and Humber College.
The history of the subway began with the Yonge subway in 1954.
This was Canada's first underground rail line. It ran under Yonge Street between Union Station and Eglinton Avenue. In 1963, the University subway opened as an extension. This new section ran northwest under University Avenue. In 1985, the Scarborough RT, or Line 3, opened.
This line used Intermediate Capacity Transit System technology. However, Line 3 closed permanently in 2023 following a derailment.
New projects are currently changing the face of the network. The Ontario Line is one major project under construction. It will be an underground line from Exhibition station to Don Valley station. This will provide the first east–west rapid transit through the Financial District. The project is expected to cost between $17 billion and $19 billion. It is scheduled for completion in 2031.
Another project is the Line 5 Eglinton west extension. This will add seven new stations to the line by the 2030s.
