Although Carson was a fine hockey player, his inclination was toward education more than it was to the NHL. He attended the University of Toronto and played on the Varsity team, winning the Allan Cup in 1921 and staying in OHA senior hockey while finishing his studies.
Carson stayed in the game for a few years, playing in Grimsby and Stratford and earning the admiration of the St. Pats, precursor to the Maple Leafs. He joined the St. Pats and NHL full-time in 1926-27, the year the team was sold to Conn Smythe and the name change made.
Carson had impressive years of 16 and 20 goals with Toronto, but midway through 1928-29 he was sold to Boston and helped the Bruins win their first Stanley Cup just a few weeks later.
Carson played one more season with the Bruins, then more or less retired to go into dentistry, the result of his studies at the U of T.
