Ontario Highway 5A

Ontario Highway 5A (1937–1953), as a former connecting link in Ontario, Canada's provincial highway system, bypassed portions of Ontario Highway 5 within what is now Toronto. There were two discontinuous segments:

• St. Clair Avenue from Ontario Highway 5 (Islington) eastward to Ontario Highway 11 (Yonge Street, Toronto).
• Eglinton Avenue from Victoria Park Avenue (then Dawes Road, Scarborough) eastward to Ontario Highway 2 (Kingston Road); renumbered as Highway 109 in 1953.
