The Revs first struck in the 10th minute after Joel Waterman blocked Carles Gil's shot from inside the box. The ball then fell straight for DeJuan Jones, whose left-footed shot gave him his third goal of the season.
Adam Buksa doubled New England's lead come the 17th minute with a powerful header. Gustavo Bou whipped in a cross to the Polish striker, who continued the dominant tone with his 13th goal of the season.
Montréal were down 3-0 a half-hour after an own goal by Rudy Camacho. The French center back tried to redirect a cross by Bou out for a corner kick, but it instead rolled into his own net.
The hosts pulled one back in the 32nd minute thanks to Joaquin Torres' individual brilliance.

His strike beat Matt Turner to the lower right-hand side and gave hope back to the home fans.
Bou added New England's fourth and final goal at the 86th minute, putting the final nail in Montréal's coffin. The Argentine latched onto a through ball, duped Waterman with a cutback inside the box and beat James Pantemis to clinch the 4-1 scoreline.
