There are also many sports teams at Churchill such as basketball, soccer, flag football, ice hockey, baseball, ultimate frisbee, rugby, cricket, volleyball, badminton, and many others.

The school colours were originally scarlet and silver, as an ode to the coat of arms of Winston Churchill, they have since been changed to black, white, grey and purple after a deal with the Western Ontario Mustangs team.
