Morgan Reilly and John Tavares scored their second goals of the playoffs to give the Leafs a 2-0 lead in the first period.
It was the first lead the Maple Leafs have had in a playoff game in 23 years.
But after blowing said 2-0 lead, the Leafs luckily managed to find their way to a 3-2 win over the Senators thanks to Max Domi's game-winner, which was his first of the playoffs.
Toronto managed to pull out the win despite being outshot 28 to 21 and outhit 44 to 21. But their 32 blocked shots to Ottawa's six proved to be beneficial in a game that looked like it would be the Senators' for the taking.
The series now heads to Ottawa for Game 3 (April 24th) and Game 4 (April 26th).

Both teams went 0 for 3 on the power play while each also had 15 giveaways. The Devils even outhit the Canes 51-31, but Martinhook's short-handed goal was a dagger to the Devils.
