We have a few Canadian clowns here on the Forum although they have not been real active lately. Try going to
Clowns of America International and clicking on the link (along the left hand side) called "Find A Clown" you should be able to look up the names of some clowns in Canada. Also get in Touch with Bridget White, her email is found on the page of officers (she is the "Canadian Connection") ans she should be able to help you out.
