You may not drive a school bus if your driver's licence has been under suspension for any Criminal Code of Canada offence committed within...?

The correct answer is based on the regulations surrounding the operation of a school bus and the implications of having a driver's licence suspended due to a Criminal Code of Canada offence. If your driver's licence has been suspended as a result of such an offence, you are prohibited from driving a school bus for a defined period, which is set at 12 months.

This timeframe serves as a safeguard to ensure that individuals operating school buses, which carry vulnerable passengers—children—are deemed responsible and safe drivers. The 12-month period allows law enforcement and regulatory bodies to assess any changes in behaviour or adherence to driving regulations, thereby enhancing safety in the operation of school buses.

The other options represent shorter periods that do not align with the established guidelines for school bus drivers following a suspension, which reinforces the importance of comprehensive evaluation regarding a driver's ability to safely transport children.
