Growing up with the cold winters of North Bay, Ontario it had the tendency of making tough men even tougher. And big Clarence Boucher was clearly a beneficiary. At 6'1" and 195 pounds he was one of the biggest and strongest players in the NOJHA when playing with the Sudbury Cub Wolves in 1920.
Boucher graduated to the senior team in Sudbury the following year and became somewhat of a scoring hero, notching 16 goals in 18 games over two seasons for the Wolves. He also spent time with the Iroquois Papermakers and the Galt Terriers of the OHA senior league before signing as a free agent with the NHL's New York Americans in the summer of 1926. Just one month before the signing, Boucher was the main focus of a bizarre event during a game on May 9, 1926 when a near riot occurred at the Guelph-Galt intermediate hockey game. Police were there when Boucher, seriously injured Guelph's George Grant with a crushing hit on the ice.
The resulting extent of bad feelings from the Guelph players and fans in the stands was such that Boucher had to escape out a rear window onto Paisley Street behind the arena where police found him and took Boucher to the station, probably as much for his own protection as anything else. Galt had beaten Guelph 5-2 in the game and they also beat Guelph in the courtroom, where the presiding judge dropped all charges against Boucher after considering the circumstances surrounding the melee.
With the court case thrown out, it left Boucher free and clear to join the New York Americans, which he did for eleven games that year. He spent the remainder of the season with the Niagara Falls Cataracts of the CPHL. In 1927-28 he was back in New York for another 36 games where he scored two goals and an assist. He also took on the role of enforcer with the Americans, as evidenced by his 129 minutes in penalties.
