Charlie McAvoy scored two goals — one coming when Boston scored three times in 70 seconds during the opening period — and the Bruins celebrated the 100th anniversary of their first NHL game with a 6-3 victory over the Montreal Canadiens on Sunday.

Boston celebrated its Centennial, with Sunday’s game taking place exactly 100 years after their first game in franchise history, a 2-1 win against the Montreal Maroons on Dec. 1, 1924. The Bruins held a pregame ceremony that featured tribute videos and appearances from franchise legends such as Bobby Orr, Ray Bourque, Patrice Bergeron and more.

The Montreal Canadiens finish their weekend twofer at TD Garden against the Boston Bruins. Although the game is scheduled to start at 3 p.m., the Bruins will celebrate their 100th anniversary with a pregame ceremony expected to last until 4:15 p.m. (SN, RDS, TSN Radio 690, 98.5 FM).
