Oakville is rapidly moving away from being some small town on the outskirts of the city with an automotive plant, to being an integral and urban part of the Greater Toronto Area. The GTA Transit 2050 Plan sees connecting the Mississauga and Oakville urban centres through the Uptown Core at Trafalgar and Dundas with an LRT to support urbanization and land use intensification along the route.
The Sheridan Line, planned to open around 2043, would start at Mississauga Centre and head west starting off travelling through dense residential areas around Cleary Park that are expanding towards Mavis Road. Continuing west the land on the south side of Burnhamthorpe between Mavis and Creditview has a number of proposals for urban intensification and this line would help to serve those developments. The line would connect to Valley Line B with surface rail throughout Mississauga at Riverwood.
East of Riverwood the line would become grade separated using both tunnels and bridges to traverse the route to Sheridan Mills (a mall set for an urban intensification plan) with stops at UTM (the growing University of Toronto at Mississauga campus) and at Erindale.
Travelling further east the route would pass through the Sheridan Park, Winston Churchill, and Winston Park employment areas before heading north slightly to run along Dundas Street westward into the growing urban Uptown Core at Trafalgar and Dundas.
From Uptown Core, the route would head south along Trafalgar, Oakville's primary north-south street, to serve Sheridan College, Oakville Place which is Oakville's primary mall, and the Oakville Centre urban core with connections to the Lakeshore Line A, VIA, and Amtrak.
