LeDuc began wrestling professionally in 1957 at age 18. He began his training in Montreal, Quebec and later moved to Mexico for further instruction. He talked a friend, Michel Pigeon, into becoming a wrestler as well. Pigeon agreed and took on the ring name Jos LeDuc, as the pair pretended to be brothers. They first worked together in Stu Hart's Stampede Wrestling promotion in Calgary, Alberta. The LeDucs used a lumberjack gimmick to honor deceased professional wrestler "Yukon" Eric Holmback. While wrestling in Stampede Wrestling, the pair held the Stampede International Tag Team Championship.
The LeDucs next moved back to Montreal. They feuded with the Rougeau family as well as the Vachon brothers (Maurice and Paul). During a wrestling show in Montreal, Paul LeDuc was legitimately married in the wrestling ring. They also held the Grand Prix Wrestling Tag Team Championship twice in 1972 and 1973.
LeDuc retired from wrestling in 1978 and began working for Quebecor, a communications company, the following year.
LeDuc's long-time friend and tag team partner died in 1999. The pair had played the role of brothers so well that, when it was revealed that they were not related, the news was widely discussed on talk shows in Quebec. Paul LeDuc's son, Carl, is also a professional wrestler.
