Kasperi Kapanen added a goal and an assist and Travis Dermott, Pierre Engvall and Mitchell Marner also scored for the Maple Leafs, who extended their point streak to nine games (8-0-1).
Semyon Varlamov made 20 saves for the Islanders (25-12-3), who are 2-4-1 in their past seven games. The Islanders are coming off of a loss to the New Jersey Devils.
The Winnipeg Jets, losers of three of their last four games, are planning to reprise their winning formula from Tuesday's 7-4 triumph in Denver when they host the Toronto Maple Leafs tonight at Bell MTS Place. There was a 10-minute stretch in the first period when neither team took a shot on goal.
Toronto got on the scoreboard with 6:35 left in the second when Kasperi Kapanen slid the puck through NY defenseman Noah Dobson's legs and then backhanded a pass to Engvall, who was skating into the slot and in a ideal position to shoot on Varlamov.
Matthews made it 2-0 at 16:07 when he chipped Marner's shot in the slot over the shoulder of Varlamov.
The Islanders continued to press - including a power play with 2:50 left in the second - but Hutchinson held firm.
Chants of "Hutchy" and "Let's go Hutch!" rained down on Hutchinson from the sections directly behind him in the lower bowl of Scotiabank Arena after he made another smart glove save on Noah Dobson with 11:43 left to play.
No goals: The Islanders allowed the fewest goals last season under National Hockey League coach of the year Barry Trotz and are back at the top of the category once again this season, tied with Boston and Dallas at 101 - but have played fewer games than both teams.
Toronto's Cody Ceci got the first penalty of the game when he was called for a kick at 17:10 of the second in a game where some players were packed in the crease of Toronto's goal.
Zach Hyman added a goalless goal in the third period. Equipment manager Brian Papineau was honored for his 2,500th game behind Toronto's bench.
After three consecutive games against bruising Central Division foes, Laine expects to see a style change with the Leafs in town.
