John Cannon (21 June 1933 – 18 October 1999) was a sports car racer, who competed under the banner of Canada, though he was born in London, U.K. He raced in the USRRC series, the CanAm Series and the L&M Continental Series (Formula 5000). In the USRRC he drove for Nickey Chevrolet in a Dan Blocker (of Bonanza fame) sponsored Genie/Vinegaroon. In the first year of the Can Am he was the top finishing Canadian propelled by a fourth-place finish in the opening event at his home course, Circuit Mont-Tremblant. Cannon duplicated that accomplishment in 1968 propelled by a famous win over the dominant McLaren team in a very wet race at Laguna Seca. He also attained top Canadian status in 1973. Cannon also ran in the Continental Series (Formula 5000) in 1969 winning races at Riverside, Sears Point and Mosport in the Malcolm Starr Eagle prepared by Tom Jobe and Bob Skinner and finishing fourth in the standings. In 1970 he won the championship after winning races at Riverside, Kent and Elkhart Lake driving for Malcolm Starr and St Louis trucking magnate Carl Hogan, in the Hogan-Starr Racing McLaren M-10B. Racing in the following Tasman series in 1971, Cannon made the M10 fast but unreliable at Levin and Wigram but against the larger field of talented drivers in the Australian races found the local experience of Matich, Allen, Gardner, Bartlett and McRae very difficult for any foreigner to match, first time in the Antipodes. Cannon participated in one World Championship Formula One Grand Prix, on 3 October 1971 in the US Grand Prix at Watkins Glen. He finished 14th, thus he scored no championship points. He also participated in one non-Championship Formula One race, the Questor Grand Prix, finishing up in 12th. During 1971 he also ran strongly in a number of rounds of the European F2 championship, impressing many. Cannon also made 15 starts in the USAC Championship Car series while driving on a part-time basis from 1968 to 1974. His best finish was 2nd place in the second race at Circuit Mont-Tremblant in 1968. He also finished a career best 27th in series points that year. He also attempted to qualify for the Indianapolis 500 in 1970 and 1974 but failed to make the race both years. In 1975-76 he returned to US F5000 series with a March 741 modified for F5000, and ran in midfield, with
