William Nylander and John Tavares each had a goal and an assist, and Oliver Ekman-Larsson, Morgan Rielly and Matthew Knies also scored for Toronto. Auston Matthews added two assists and Anthony Stolarz stopped 31 shots.

For the first time since 2017, the Ottawa Senators returned to the playoffs to take on their old rival, the Toronto Maple Leafs, in a highly anticipated Battle of Ontario matchup.

The Leafs, who beat the Senators four times in the playoffs across a five-year stretch in the early 2000s, returned to the NHL postseason in 2017 — the last time the Senators made it — with a young core led by Matthews, Marner and Nylander.
