Leaside Station will be an underground Station located at the intersection of Bayview Avenue and Eglinton Avenue East. 

The Crosstown is a 19-kilometre light rail transit line (LRT) that will run through the heart of Toronto. Running along Eglinton Avenue, the LRT will connect west to east from Jane Street/Black Creek Drive to Kennedy Station. Ten kilometres will be tunnelled underground between Keele Street and Laird Drive and will continue east on an at-grade right-of-way separated from traffic to Kennedy Station, where it will join with a converted Scarborough RT line on an elevated structure. Construction of The Crosstown began in the summer of 2011, and has a projected completion date of 2021.

The Crosstown will cut travel time significantly and conveniently link to 54 local bus routes, three TTC interchange subway station and GO Transit. Travel along The Crosstown from Kennedy to Black Creek Drive will be significantly faster and more comfortable than current bus travel. It's modern, fast, reliable, comfortable and environmentally friendly.

All Crosstown stations will accept the new PRESTO payment card system. Light-rail vehicles will feature low floors. Stations will have a main entrance with elevators, making the system accessible to all passengers.
