The Sens remain two points back of the Penguins, Red Wings and Bruins. All four clubs have three games remaining.
With Ottawa’s loss, the Washington Capitals have clinched a berth in the playoffs.
Joffrey Lupul opened the scoring at 3:10 of the first.
After Erik Karlsson scored his 21st of the season to tie it 1-1, James van Riemsdyk gave Toronto a 2-1 lead.
Karlsson becomes the first Senators defenseman in franchise history to record 21 goals in a single season. With his assist on the goal, Kyle Turris established a new career high for points in a season (59).
Mark Stone netted his 22nd of the season 1:09 into the third to force overtime.

Flyers GM Ron Hextall announced today that defenseman Luke Schenn is “unlikely to play the rest of the season” due to a lower-body injury.
“We will give final medical information when we have it in full,” said Hextall.
Assuming he doesn’t play again, Schenn will finish 2014-15 with three goals and 11 assists in 58 games. The 25-year-old is signed through next season, after which he can become an unrestricted free agent.
Schenn was traded from Toronto to Philadelphia in 2012, in return for James van Riemsdyk. The fifth overall pick in 2008, Schenn has mostly struggled to live up to his draft pedigree.
Tyler Bozak netted his first career hat trick and added an assist while line mates Phil Kessel and James van Riemsdyk each had three assists in the win.
An Ottawa win would’ve vaulted the Sens back into the playoff picture. With the loss, the Senators remain a point back of the Boston Bruins for the second wild card spot in the Eastern Conference. Ottawa has one game in hand on Boston.
