1942–43 NHL season

Teams and format

After changes at the end of the previous season the circuit consolidated to six franchises. These clubs competed under the NHL's established schedule and playoff structure, with the top teams advancing to the postseason for a shot at the league championship. The six clubs of the era are often listed together in discussions of this period:

• Boston Bruins (Boston)
• Chicago Black Hawks
• Detroit Red Wings (Detroit)
• Montreal Canadiens
• New York Rangers
• Toronto Maple Leafs

Historical context

Two developments give this season special historical significance. First, the reduction to six teams marked the beginning of a long-lived era in which these franchises dominated the league's identity and scheduling until expansion in 1967. Second, the NHL suffered the loss of its long-serving president, Frank Calder, who died during the season; his death prompted an immediate change in the league's governance and was widely reported at the time (Calder).

Playoffs and champion

The postseason concluded with the Detroit club prevailing over Boston to capture the league championship and the Stanley Cup. The title series and Detroit's victory are commonly cited as a defining moment early in the Original Six period, reinforcing the competitive rivalries among the six remaining clubs.

Legacy and notable facts

The 1942–43 season is remembered less for statistical records than for its structural and historical consequences. It established a roster of six teams that would frame professional hockey in North America for a quarter-century, shaped by wartime constraints and administrative change.
