Unfortunately, some brazen thieves have cut a bike lock and ridden away with a student bike. Students who ride to school are encouraged to wear a bike helmet which they should store in their backpack or locker and to lock their bike up using a "D" or "U" lock. These are the hardest ones to cut according to the City Police. You can purchase a "D" lock from many retailers such as Canadian Tire, Walmart, Western Cycle etc.
