Burger King was a fast food restaurant chain in Edmonton, Alberta, Canada. Also known as Burger King Drive-Inn, it was founded by former Imperial Oil executives William R. Jarvis (1926-21 July 2014) and James Duncan Rae (3 September 1923 - 17 December 2014) in 1956. Among the first American-style fast food restaurants in Edmonton, it was not related to the worldwide Burger King chain. Company headquarters were in offices above one of the restaurants, at 9501 111 Avenue. Its signature items included a mushroom burger and a "Canadian Burger". Several Burger King restaurants became Burger Barons.
