Which team won the 1951 Final, the only NHL playoff series where every game went to overtime?

The Toronto Maple Leafs won the 1951 Stanley Cup Final, the only NHL playoff series in which every game went to overtime. Toronto defeated the Montreal Canadiens four games to one.

All five games required extra time, an extraordinary sequence in a best-of-seven championship series. The deciding fifth game ended when Toronto defenseman Bill Barilko scored at 2:53 of overtime, giving the Maple Leafs a 3–2 victory.

Barilko’s goal became one of hockey’s most famous championship moments because it was his final NHL goal. He died in a plane crash later that summer, and the story was later immortalized in the Canadian song “ fifty Mission Cap.”

The 1951 title was Toronto’s ninth Stanley Cup and completed a run of six championships beginning in 1942. It was also the first of ten consecutive Final appearances for Montreal, which returned to the championship series the following season.
