Maple Leafs vs Senators: H2H, playoff history and more key details to know about 'Battle of Ontario'

The Battle of Ontario is back. For the first time since 2004, the Toronto Maple Leafs and Ottawa Senators will square off in the first round of the Stanley Cup Playoffs.

As the winners of the Atlantic Division, Toronto (106 points) will have home ice advantage against Ottawa (95 points), the top wildcard in the East.

In what may come as a surprise to some, Ottawa swept the season series in 2024-25, holding Toronto to just three goals in those three games.

While the Maple Leafs will be the favorites, this should be an extremely hard-fought series that has the potential to go the distance.

Maple Leafs vs. Senators: More key details

Both teams are dealing with some key injury concerns heading into the playoffs.

David Kampf (upper body), Oliver Ekman-Larsson (upper body), and Jake McCabe (upper body) have all been sidelined from recent games, though there appears to be optimism they will be good to go for game one.

For Ottawa, the lone injury absence has been captain Brady Tkachuk (upper body). The star winger could return for the Senators' season finale on Thursday night, which is a positive sign for his postseason status.

When it's all said and done, this series will come down to the Toronto Maple Leafs' star players. Specifically, Auston Matthews, Mitch Marner, and William Nylander. They are the three best players from either team and must perform up to that level for the Maple Leafs to advance. Each team has solid depth and strong goaltending, which leaves it up to Toronto's elite talent to push them over the edge.
