Line 5 Eglinton

Line 5 Eglinton, also known as the Eglinton Crosstown LRT or the Crosstown, is a light rail transit line in Toronto, Ontario, Canada. Operated by the Toronto Transit Commission (TTC) as part of the Toronto subway, it has 25 stations and is 19 kilometres (11.8 mi) long. Service on the line began on February 8, 2026, as part of a phased opening. It uses standard gauge rather than the broad Toronto gauge used by the three older heavy rail subway lines.

The line was conceived in 2007 during the administration of Toronto mayor David Miller as part of Transit City, a large-scale transit expansion plan that included several light rail lines proposed across the city. While the plan was later dropped by successive municipal governments, only the Eglinton Crosstown LRT received support and funding from the Government of Ontario under Premier Kathleen Wynne.

The line's construction was overseen by Metrolinx in two phases. The first phase of the 19-kilometre (12 mi) line includes 25 stops along Eglinton Avenue, from Mount Dennis station mostly underground to Laird station, after which it runs predominantly at-grade within the street's median to Kennedy station in Scarborough, where it connects underground with Line 2 Bloor–Danforth, and GO Transit. Automatic train control is used in the tunnelled sections. This first phase had an estimated cost of CA$12.82 billion; the cost when the contract was awarded was pegged at $9.1 billion, although the cost was originally estimated at $11 billion.
