Following a suggestion by his wife, the late Claude Aubin started his racing career at Autodrome Laval (then named Riverside Speedway) in 1966. He won the Hobby Fast class title in his rookie season, before moving up to Sportsman and Late Model competition. He won four championships in the ACAQ touring series in the 1970s, following them up with five titles in the ACCAS series in the 1980s.

Aubin competed in select NASCAR Late Model Sportsman (now Xfinity Series) events in the 1970s and early 1980s, including the Dogwood 500 at Martinsville Speedway. He won multiple NASCAR Late Model Sportsman races at Catamount Stadium in Vermont. He also competed in a Daytona 500 qualifying race in 1978 and won a pair of NASCAR North Series races in Quebec in 1979. He later raced in the GM Players Championship and CASCAR.

Away from the driver’s seat, Aubin helped grow stock car racing in Quebec. He purchased Autodrome Laval in 1979, renovating the track and giving it that new name. He also leased the St-Félicien race complex in 1981 and purchased Le Circuit Deux-Montagnes in 1982. In 1985, he sold Autodrome Laval to the city and moved the modern facilities to Deux-Montagnes, where he re-paved the oval and re-named it Autodrome St-Eustache.

Aubin founded his own stock car driving school, as well as the Légendes Modifiées series, with the latter helping many drivers begin their racing careers due to the cars being less expensive to build. He sold St-Eustache in 2006, after 21 years of ownership. Aubin passed away in August 2022 at the age of 82.
