The Oakville Refinery, also known as the Trafalgar Refinery, was an oil refinery located in the western portion of Oakville, Ontario, adjacent to the boundary with Burlington. Opened in 1958, it was acquired by BP Canada in 1963 and by Petro-Canada in 1982, when all of BP's Canadian assets were sold. The refinery operated until it was closed in 2005. An oil storage facility remains on the site.
