The Montreal Canadiens have two historically significant rivalries:
Boston Bruins:
This rivalry is considered one of the greatest in all of sports.1 The two teams have a long and intensely competitive history, with numerous memorable playoff matchups.
Toronto Maple Leafs:
This is another classic «Original Six» rivalry. It’s one of the oldest rivalries in the NHL.
While both are very large rivalries, many would argue that the Boston Bruins rivalry is the most intense. This is due to the sheer number of playoff meetings and the overall length of the rivalry.
