Led by skipper and star striker Juan Pablo Angel who netted a hat-trick, the Red Bulls dominated proceedings to continue their undefeated pre-season.
Estonian recruit Joel Lindpere set up the first goal for Angel just after the half-hour mark and then the Colombian ace netted again five minutes later.
A third goal and Angel's hat-trick came just after the break but he then limped from the pitch in the 69th minute when Toronto's Julian de Guzman laid him out with a poor challenge. Medical staff are hopeful the knee injury is not too serious.
The win was rounded out five minutes from time when Conor Chinn headed home from an Austin da Luz cross.
