William Nylander scored a goal and an assist when Toronto broke Vegas' winning streak.
Before the match, Vegas had three straight wins, but against the Maple Leafs they had no chance.
Mitchell Marner started the scoring before Auston Matthews struck twice.
William Nylander then set the final score at 4-0 behind compatriot Robin Lehner in the Vegas goal.
The goalkeeper saved 29 shots, something that did not save Vegas from a big loss.
- That was not even close enough good, probably our worst (match) since I came to Vegas, said Robin Lehner according to TT.
Pierre Engvall, Toronto's second Swede, not only celebrated the victory but also his 100th game in the NHL.
