After being drafted by the Quebec Nordiques of the National Hockey League (NHL) in the fourth round of the 1989 Entry Draft, Dubois went on to play seven seasons in the minor leagues from 1991 to 1997, primarily with the IHL's Atlanta Knights, Chicago Wolves, and Manitoba Moose. This included a Turner Cup championship with the Knights in 1994. He also played another five seasons in Europe, including three in the DEL and two more in British Ice Hockey Superleague. He retired from full-time professional hockey in 2002, but played one season for the semi-professional Sorel Royaux before retiring for good.
