Not to be confused with Oscar "Ossie" Asmundson who played just a few years previous with the four Original Six teams Aubuchon did not play for, this Ossie started his career with the Montreal Jr. Canadiens before moving to Britain to continue his career.
After two years with the Brighton Tigers, Aubuchon returned to North America in 1939 until Boston gave him an NHL chance during the 1942-43 season, though he spent most of the year in Providence. Just nine Bruins games into the following season, he was sold to the Rangers where he finished the season as a wartime replacement (Ossie had been given a medical discharge).
Aubuchon never played in the NHL again. He played two more years of minor pro, then returned to Quebec to play senior hockey until retiring in 1947.
