Although the Red Wings opened the scoring in the first period, the Maple Leafs won 3-1 to become the first three-peat team in NHL modern history -- an original dynasty. In the winner's dressing room, Day dipped his finger into the champagne-filled Stanley Cup and shouted, "You're seeing a Happy Day at night!"

With their 4–0 victory over the Buffalo Sabres, the Leafs secured the division title and set up a long-awaited playoff rematch against the Ottawa Senators. This is the Leafs' first full-season division crown in 25 years and their first since the NHL created the Atlantic in 2013.
