The Ontario Line

The Ontario Line

Announced by the Province of Ontario in 2019, the proposed Ontario Line is one of four priority transit projects Metrolinx is leading for the Greater Toronto and Hamilton Area (GTHA). The line will be the largest single expansion in Toronto’s subway history, helping to ease congestion on existing transit lines throughout the city and bring transit to underserviced neighbourhoods.

The proposed Ontario Line will bring nearly 15.5 kilometres of much-needed subway service to Toronto to make it faster and easier for hundreds of thousands of people to get where they need to be each day.

The line will stretch across the city, from the Ontario Science Centre in the northeast to Ontario Place in the southwest.

Current plans for the Ontario Line include 15 proposed stations, including six interchange stations and 17 new connections to GO train lines and existing subway and streetcar lines.

The Ontario Line will make it much faster to travel across the city.

From Thorncliffe Park, a commute to the heart of downtown would be 25 minutes instead of the current 42.

It will take five minutes less to get from Pape Station to Queen Station, from 18 minutes today to 13 on the Ontario Line.

The Ontario Line could reduce crowding by as much as 15% on the busiest stretch of the TTC’s Line 1. It would significantly reduce crowding at numerous stations across the network, including the following key transfer points:

• Bloor/Yonge Station - 19% less crowding
• Eglinton Station - 17% less crowding
• Union Station - 16% less crowding
