Toronto scored four goals on only 14 shots.
The Leafs improved to 6-1, continuing their best start since 1993, when they opened with 10 straight wins.
Because of penalties, the Wild spent more than a quarter of the first period on the power play. That meant Reimer faced plenty of shots and was the Leafs' best penalty-killer.
Minnesota goalie Darcy Kuemper struggled with little action.
Trevor Smith beat the Wild's No. 3 goaltender between his legs at 13:51 of the first period on Toronto's third shot of the game.
Jason Pominville scored a power-play goal for Minnesota with 2:33 left in the first period.

Corey Crawford finished with 32 saves, then stopped three Carolina shooters in the shootout.
Crawford then stuffed Jeff Skinner to end it, making the Blackhawks the last of the Original Six to reach the 2,500-win mark.

The Sabres were on the verge of their eighth straight loss, which would've set the club's futility mark to start a season, before Foligno rescued them.
