Driver's Handbook, Stopping for school buses:
You must stop whenever you approach a stopped school bus with its upper alternating red lights flashing, regardless of whether you are behind the bus or approaching it from the front. When approaching the bus from the front, stop at a safe distance for children to get off the bus and cross the road in front of you. If you are coming from behind the bus, stop at least 20 metres away. Do not go until the bus moves or the lights have stopped flashing.

School Bus Safety - Information for riders, parents and motorists: Drivers - always stop for the bus
Whether on a city street, highway or county road, and regardless of the speed limit and the number of lanes, motorists travelling in both directions must stop when approaching a stopped school bus with its upper red lights flashing. A flashing stop arm will swing out while passengers are boarding or leaving the bus. (The only exception: on highways separated by a median, traffic coming from the opposite direction is not required to stop). Once all passengers have boarded, the STOP arm will fold away. Do not start moving until the red lights have stopped flashing and the bus begins to move.
PENALTIES FOR NOT STOPPING
First offence: $400 to $2,000 and six demerit points
Each subsequent offence: $1,000 to $4,000, six demerit points and possible jail time up to six months
