Hart's career began in his home province of Saskatchewan where he spent four years playing senior hockey before he was signed by the Victoria Cougars of the Pacific Coast League as a free agent in 1923. Hart was a league All-Star his first season on the strength of 15 goals in 29 games. After his third season with Victoria the franchise was purchased by the Detroit Cougars of the NHL, which meant a transfer of his rights.

Hart played just a handful of games with the Cougars before a December 16, 1926 trade sent him to the Montreal Canadiens. There's some dispute as to how many games Hart played for bleu blanc et rouge that season with the estimates ranging from 32 to 40, but what is known is that the left winger managed three goals and as many assists.

The following year he was back with Montreal and once again fired home three goals, this time in 44 contests.

Gizzy spent all of the next four years toiling in the minor leagues with the Providence Reds, but the Canadiens finally summoned him again during the 1932-33 campaign. Hart suited up for 18 games and was able to assist on three goals for the Canadiens. That spring he played two playoff games, brining his career total to eight post season appearances and registered his only point when he assisted on a goal.

The 1933-34 season saw Hart return to Providence for one more season before he decided to hang up his blades and make the move behind the bench. In his first season of retirement Hart returned to his hometown of Weyburn, Saskatchewan to take the coaching reigns of the club where he began his hockey career.
