The 1922–23 NHL season was the sixthseason of the National Hockey League. Four teams played 24 games each. The Ottawa Senators defeated the Montreal Canadiens for the NHL championship, and then defeated Vancouver and Edmonton to win the Stanley Cup.
At the start of the season, Newsy Lalonde found himself moving west as the Montreal Canadiens traded him to the Saskatoon Sheiks of the Western Canada Hockey League for a rising young star named Aurel Joliat. Joliat would help the Canadiens win the second playoff spot over the St. Patricks. Joliat scored two goals in his first game with the Canadiens, but Babe Dye had five goals in the Toronto St. Patricks‘ 7–2 win. Joliat finished with 12 goals and 21 points in 24 games.
On January 31, 1923, the Montreal Canadiens and Hamilton Tigers played the first penalty-free game in NHL history, a 5–4 Montreal victory.
On February 14, 1923, CFCA, the radio station of the Toronto Daily Star, broadcast the third period of the Senators-St. Patricks game in Toronto. This was the first radio broadcast of an NHL game. The broadcaster has not been identified, but it may have been Norman Albert who broadcast the Midland-North Toronto game February 8 from the Toronto Arena.
