Burnhamthorpe Road is a major arterial road in the cities of Toronto and Mississauga, Ontario; beginning at Dundas Street (from which it initially angles away from before running parallel with), near Islington Avenue, running west and becoming a rural road in the Town of Oakville, where it terminates (after breaking) at Tremaine Road, where it changes name.
Unlike most major streets originating in Toronto and continuing into the "905" suburbs, only a short portion is located in Toronto and the street is strongly Mississauga-centric. Also, although Burnhamthorpe is commonly seen as the latter city's main east-west street, the parallel arteries of Dundas Street and Eglinton Avenue are (with the notable exception of the City Centre area) busier and have heavier commercial uses along them overall[citation needed].
The north side of the right-of-way on the street's eastern half through Mississauga is unusually wide as the result of being reserved for a potential light rail transit line that was never built.[1] The reserve was converted into a bicycle trail,[2] with another transit facility (the Mississauga Transitway) being constructed farther north instead.
In Mississauga, the street, unlike most other arterial roads in the regional municipalities surrounding Toronto proper, is not a regional road. However, in Oakville it is signed as Halton Regional Road 27 as far west as Neyagawa Boulevard.
