High Quality Content by WIKIPEDIA articles! Square One Bus Terminal is located on Station Gate Road, between Chapters and Playdium, in Mississauga, Ontario, Canada. This regional GO Transit facility is conveniently situated directly across from the City Centre Transit Terminal at 200 Rathburn Road West, the main hub for local Mississauga Transit bus service. The name comes from its proximity to Square One Shopping Centre, a large regional shopping mall. Although much of the bus traffic through this terminal is off-peak service along the Milton GO Train corridor from downtown Toronto, there are several bus only routes which intersect here; the Oakville to Finch, Guelph to Cooksville and Highway 407 West routes.
