Here are the latest developments on the Ontario Line map as of 2026:
-
Tunneling has begun along key downtown segments, with two tunnel boring machines starting twin tunnels from Exhibition toward the Don Yard, marking a major construction milestone for the 15.6-kilometre line [Canada.gov / 2026 progress coverage]. This milestone accompanies a broader government acknowledgment of ongoing progress in 2026, including new station names and enhanced rider navigation around the downtown core.[2]
-
Four downtown stations have been renamed to better reflect the neighbourhoods they serve, part of a federal-provincial-municipal push to improve clarity for riders as construction continues, including an elevated guideway segment approaching Don Valley and connected transit options [Canada.gov / 2026 progress coverage].[2]
-
The Ontario Line project page continues to outline a 15-station underground-dominant route totaling about 15.6 kilometres, with expected connections to multiple TTC lines, GO services, streetcar routes, and bus networks—emphasizing the mix of underground and elevated segments and a target completion in the early 2030s [Ontario Line project overview].[5]
-
In public-facing materials, Metrolinx maintains detailed project maps and key facts (stations, end-to-end travel time, connections, and route length). The project is positioned as delivering a roughly 30-minute end-to-end trip with over 40 transit connections once complete, though exact station-by-station maps may be updated as design progresses [Ontario Line page].[5]
Illustrative note:
- If you’re planning a trip soon, expect temporary street/road adjustments around construction zones and temporary traffic plans around major construction sites, which Metrolinx and the city have periodically published to help riders adapt during tunneling and elevated guideway work [Ontario Line project updates].[1]

Today, the Government of Canada celebrated continued progress on the construction of the Ontario Line subway. Tunnelling has officially started on the Ontario Line, marking a major milestone in the project. New names have also been unveiled for four downtown stations to better reflect the neighbourhoods they will serve and make the line easier for riders to navigate.
