Mitch Marner had a goal and two assists as the Toronto Maple Leafs dumped the Ottawa Senators 6-2 to take Game 1 of their first-round playoff series Sunday.

It’s been more than two decades since the Toronto Maple Leafs and Ottawa Senators squared off in a Stanley Cup Playoff series. But on Sunday night, that changes, as the rivalry is renewed in the latest edition of the Battle of Ontario.

That series kicked off a span in which the Maple Leafs and Senators met in the playoffs four times in five years (2000-2004). The fact that Toronto won all four series, with its supporters invading Ottawa in each of them, only irked Senators fans even more.
