The Eglinton Crosstown west extension will extend the Toronto subway's Line 5 Eglinton west of Mount Dennis station to Renforth station in the adjacent City of Mississauga. The 9.2-kilometre (6-mile) extension will add seven new stations – four underground, two elevated and one within an open trench.

The extension will continue the line westward along Eglinton Avenue from the existing Mount Dennis station at Weston Road. After a short tunnel, a 1.5-kilometre (0.93 mi) elevated structure will take the line over the Humber River, with two elevated stations located at Jane Street and Scarlett Road. The line will then head into a 6.3-kilometre (3.9 mi) tunnel, with four underground through-stations to be located at Royal York Road, Islington Avenue, Kipling Avenue, and Martin Grove Road. The line will then terminate at Renforth, a trenched station located beside the eastern terminal station of the existing Mississauga Transitway, a bus rapid transit (BRT) facility used by MiWay BRT routes and GO Transit bus routes.

Preliminary construction work began in 2020 when the first phase of Line 5 was itself under construction, with the tunnelling contract awarded in 2021. Forecast to serve 96,700 daily riders, the project was estimated in 2026 to cost CA$3.97 billion to construct. Metrolinx has proposed extending the line farther to Toronto Pearson International Airport in the future.
