Chevrolet Grand Prix

The Molson Diamond Indy was an annual USAC Championship Car race. It was held in Bowmanville, Ontario, Canada. It was held from 1967 to 1968 and again from 1977 to 1978. In 1967, the first ever Indy race held in Canada was the Telegram Trophy 200, held at Mosport Park in Bowmanville, Ontario as part of the USAC Championship Car season. The race was won by Bobby Unser for his first career Indy victory. Following Dan Gurney’s victory in 1968, a group led by John Bassett and Imperial Tobacco made the first proposal to run both the 1969 Telegram Trophy Indy race and the Formula One Canadian Grand Prix at a new street circuit along Lake Shore Boulevard and through Exhibition Place with the start/finish line and pits to be located inside Exhibition Stadium. Bassett dropped the idea just as the bill was going through third reading before Toronto city council. After a nine-year absence, IndyCars returned to the Toronto area for the Molson Diamond Indy at Mosport Park won by A. J. Foyt in 1977 and Danny Ongais in 1978.
