Professional boxing career
Leduc turned pro in 1992 and had limited success. He retired in 1993 with a record of 6-1-0 after losing to Michel Galarneau.
Retirement and coming out
In 1993, Leduc spoke about being a gay athlete in CBC Radio's documentary "The Last Closet", which aired on the weekly sports series The Inside Track; as he was not yet ready to officially come out, the interview was aired anonymously and recorded through a voice filter. Another Canadian athlete who would also subsequently come out as gay, Mark Tewksbury, also granted an anonymous interview to the same program. In 1994, Leduc officially came out as gay in the TV documentary For the Love of the Game, one of the few boxers ever to do so. He also later volunteered as a speaker and mentor for various LGBT youth groups.
He attended Toronto’s Pride Parade in 1999 as grand marshal with Savoy Howe. Leduc worked for and volunteered with the Toronto People with AIDS Foundation, later becoming a set-builder and construction worker in the film industry.
