|1.||Battle of Ontario|
When the NHL's Toronto Maple Leafs and their arch-rivals, the Ottawa Senators, play each other. Intense during regular season but even more so during the playoffs. Every Battle of Ontario in the post-season has been won by the Maple Leafs(4-2 in 2000, 4-0 in 2001, 4-3 in 2002, 4-3 in 2004).
The Battle of Ontario will be decided tonight during game 7 at the Air Canada Center.
