Having last met in the 1941 Stanley Cup Semi-finals where the Bruins defeated the Leafs 4 games to 3 on their way to their third Stanley Cup, the Leafs defeated the Bruins in a tight five game series where three games were decided by one goal, including an overtime game. Six goals by Ted Kennedy led the Leafs.
Game 2 in Toronto was decided by power plays and the Leafs Ted Kennedy. An early penalty to the Bruins Fern Flaman saw Kennedy score his first on the PP. A slash by the Leafs Howie Meeker resulted in the Bruins Johnny Peirson score his first career playoff goal on the PP to tie it up. At 18:24, the Bruins Clare Martin took a tripping penalty and Kennedy scored his second on the PP. A minute into the second period, Meeker took another slashing penalty and Pete Babando tied it at 2-2 on the PP. Showing he didn't need a man advantage to score, Kennedy potted his third and then fourth goal of the game and the Leafs took a 4-2 lead into the third. Max Bentley put the Leafs up 5-2 before Milt Schmidt made it 5-3. The Leafs headed to Boston up 2-0 in the series.
Game 3 at the Boston Garden saw the Leafs dominate the Bruins throughout the game. By the end of the second period, the Bruins had only 5 shots on goal. Leafs goals by Meeker, Bill Barilko and Kennedy was responded to by Milt Schmidt on a rebound and the Leafs led 3-1. The third period got out of hand once Garth Boesch added another goal for the Leafs and a scrap broke out. A late goal by Nick Metz had the hometown crowd fuming and a fight occurred between Bruin fans and the Leafs Wally Stanowski. Stanowski's teammates came to his aid and the Leafs beat a hasty retreat to their dressing room with a 5-1 win and 3-0 stranglehold on the series.
Game 4 at Boston saw nearly 70 policemen posted to prevent a re-occurrence of Game 3's altercation with the fans. The game was cleanly played with the Bruins Ed Sandford scoring the only goal of the first period. Bill Ezinicki tied it up in the second before Johnny Peirson put the Bruins ahead again. At 13:24 of the third, Peirson scored again which would hold up as the winner when Apps scored with 4:52 left. The Leafs held a 3-1 series lead.
Game 5 in Toronto was a tight checking affair with the Bruins Jimmy Peters opening the scoring on the power play 5:20 into the game. Leafs third liners Vic Lynn and Murray Costello responded and the Leafs led 2-1 at the end of the first period. The Bruins Kenny Smith tied the game at 12:08 of the second. Both teams attempts to break the deadlock were stunted by Turk Broda and Frank Brimsek until Kennedy took a Meeker pass and picked the top corner over Brimsek's shoulder at 5:52 of the third. The Bruins couldn't counter and the Leafs took the series 4-1.
