Dakota Joshua scored the game-winning goal eight seconds after captain Auston Matthews tied the game on a late power play.
Wyatt Kaiser and Jason Dickinson, shorthanded, scored for the Blackhawks, while Oliver Ekman-Larsson got the Maple Leafs on the board in the third period.
Matthews’ assist on Ekman-Larsson’s goal was his first point after being held off the scoresheet Saturday against the Edmonton Oilers.
