An interference penalty called against forward Ryan Smyth nullified a possible tying goal from teammate Milan Hejduk, and eventually led to the Toronto Maple Leafs' 7-4 victory over the Colorado Avalanche on January 29, 2009. Hejduk's no-goal call was made early in the third period, and prevented the Avalanche from making a complete comeback on home ice. Toronto goals from Jason Blake, Matt Stajan and Dominic Moore clinched the victory for the Maple Leafs, in a game far closer than the final score indicates. Nik Antropov opened the scoring for Toronto, but was answered by Colorado's Chris Stewart and Hejduk. Mikhail Grabovski and former Avalanche Jeff Finger answered for Toronto, while Hejduk scored for a second time to even the score in the back-and-forth game. Moore took the lead back for Toronto late in the second period, and the Maple Leafs never relinquished the lead again. Hejduk's rejected hat trick goal proved to be the pivotal moment of the third period, as the Maple Leafs dominated the period following the incident on route to victory. The victory was only Toronto's fourth in their last 16 games.
The Toronto Maple Leafs-Ottawa Senators rivalry, also known as the Battle of Ontario, is one of the most prolific rivalries currently in the National Hockey League. The two teams compete for the large hockey fanbase of Ontario, and are known to have very divided sets of fans.
While the rivalry between Toronto and Ottawa-based franchises can date back to before the founding of the National Hockey League, the true animosity between the two hockey cities developed in the latter half of the 1990's. When the NHL re-aligned its teams into new divisions before the 1998-99 season, the Maple Leafs were placed in the Northeast division along with the Senators. Concurrent with this division realignment, the Maple Leafs and Senators each developed elite contending teams within the Eastern Conference. Because of the highly competitive teams produced by both franchises, and the frequency with which the two played each other, the teams began to develop an intense rivalry that spanned the province of Ontario.
While the Senators were the better of the Maple Leafs during the regular season on occasion, the team was never able to overcome its playoff failings. Between 2000 and 2004, the Maple Leafs and Senators met each other in the post season a total of four times, with the Maple Leafs claiming series victory each time. However, since the two team's most recent playoff encounter during the 2003-2004 playoffs, the Maple Leafs have failed to qualify for the NHL post-season. Hence, the rivalry appears to have tapered off slightly, at least in terms of on-ice tension. Nonetheless, the Battle of Ontario remains a topic of heated debate among hockey fans in southern Ontario...
