Cec Browne attended school at Isbister and Kelvin where he became proficient in many sports. As a thirteen-year-old, Browne was a member of the Free Press Industrial Hockey League team, the Kelvin soccer team, and won numerous track and field medals as well as swimming awards in the city. At the age of twenty-two, Browne coached the Argonauts Hockey Team to the Manitoba Juvenile title and also played for the Canada Packers Provincial Senior Hockey Champion squad.
Browne participated in three Allan Cup finals with the Winnipeg Senior Monarchs in 1915-16, the Regina Victorias in 1923, and the famous Selkirk Fishermen in 1924. While in Saskatchewan, Browne played football for the Regina Roughriders and was named the province's all-round track and field champion.
As a baseball player, Browne was a member of Dick Irvin's Dominion Express team which was in the Winnipeg Senior League.
Browne was a charter member of the Chicago Black Hawks team that entered the National Hockey League in 1926. However, injuries in his first year led to his contract being sold to the Seattle Eskimos of the Pacific Coast League. From 1928-30, Browne was the league's scoring champion which led to the Boston Bruins' purchase of his contract in 1930. However, Browne decided that his athletic career was complete and instead retired back to Winnipeg. Browne remained active in amateur sport as a coach in junior hockey and as a player for teams in the industrial league. The highlight of his coaching career occurred in 1936 when his Elmwood juniors reached the Western Canadian Junior Final.
At the age of 75, Cec Browne was voted Manitoba's Athlete of the Century (1870-1970) during the province's Centennial celebrations.
