Barker Field was one of several airfields in the Downsview area of Toronto, Ontario.
Opened in 1927, it was a civilian airfield for the early era of flying in Canada and was named after William George Barker, a First World War fighter ace and Victoria Cross recipient. It remained in use until 1953. The area (northwest corner of Lawrence Avenue West and Dufferin Street) has since been re-developed as a commercial site (auto dealership, gas station and other businesses).
