Indeed, in Toronto at least, bicycles with rims larger than 24" are prohibited from riding on sidewalks. One can be ticketed even if their rim-size is below 24". If they fail to respect pedestrian traffic, they can be cited.
To the OP: it is best to check your municipality bylaws. Keep in mind, many areas do not enforce the bylaw and fines can vary. But moreover, it is extremely dangerous to ride on sidewalks, legal concerns aside. Pedestrians step out unexpectedly, motorists exiting narrow alley-ways have little or no peripheral views and there are often uneven surfaces and other barriers, hazards that are hard to see until it's too late and even harder to avoid due to the constriction of space. Learn to ride on the road. It is considerably safer and more enjoyable.
