If Boston win at home tonight , the Stanley Cup Finals will manoeuver back to Canada for a deciding Game 7 . If Vancouver wins , the Canucks will clinch their first Stanley Cup in three tries . But what if the team link up ?

It ’s extremely unlikely that tonight ’s plot will cease in a draw . After all , Rule 84.5 of the NHL rulebook dictates that when a Stanley Cup Playoff game is tied at the end of regulation , the team will play 20 - second overtime periods , and the team scoring the first end will be declare the winner . But since 1927 , there have been three tie in Stanley Cup Finals history , and all three have involve the Bruins .

In 1927 , the Bruins and Ottawa Senators play to a 0 - 0 tie in Game 1 of what was supposed to be a best - of - three series . NHL President Frank Calder decided that the ice at the Boston Garden was unplayable after two 10 - instant overtime periods and called the game . Calder predominate that subsequent games would apply the same two - extra time formatting and that if the series was n’t decided after five game , the Bruins and Senators would share the title . Ottawa won Game 2 . The teams tied Game 3 .

As Seabury Lawrence wrote inThe New York Timesbefore Ottawa ’s 3 - 1 win to clench the series ( 2 - 0 - 2 ) in Game 4 , “ These deadlocks have lead in so many ifs , ands and buts being insert into the billet that it will probably go down in history as the hypothetic hockey series . ”

There was n’t another tie in the Stanley Cup Finals until 1988 , when the power went out at the Boston Garden with the Bruins and Oilers tied 3 - 3 in the second menses of Game 4 . The game was suspended and replayed in its entirety two nights subsequently in Edmonton , where the Oilers win 6 - 3 to finish a four - plot sweep . “ The Americans will call it 4 - A , ” Edmonton star Wayne Gretzky say of the relocated game . “ We ’ll call it 4 , eh ? ”

Note : We fail to name the tie in Game 4 of the1919Stanley Cup Finals . That class , the series was called off due to an influenza eruption . Thanks , Jeff !
