The Mississauga Transitway is a bus rapid transit (BRT) system in Mississauga, Ontario, Canada. It comprises a series of purpose-constructed bus-only roadways, as well as reserved lanes on existing city streets and portions of Highway 403, that together form a continuous 18 km (11 mi) route spanning most of the city from Winston Churchill Boulevard in the west to the junction of Highways 401 and 427 in the east on the border with Toronto. Service on the Transitway is provided by MiWay and GO Transit, with some stations providing connections to Brampton Transit and Toronto Transit Commission (TTC) bus services.

King's Highway 403, or simply Highway 403, is a 400-series highway in the Canadian province of Ontario that travels between Woodstock and Mississauga, branching off from and reuniting with Highway 401 at both ends and travelling south of it through Hamilton and Mississauga. It is concurrent with the Queen Elizabeth Way (QEW) for 22 km (14 mi) from Burlington to Oakville. The Highway 403 designation was first applied in 1963 to a short stub of freeway branching off the QEW, and the entire route was completed on August 15, 1997, when the section from Brantford to the then-still independent Town of Ancaster was opened to traffic. The section of Highway 403 between Woodstock and Burlington was formally dedicated as the Alexander Graham Bell Parkway on April 27, 2016, in honour of Alexander Graham Bell.
