Impaired driving by alcohol or a drug

MTO Driver’s Handbook: Keeping Your Driver’s Licence, Impaired driving

Driving when your ability is impaired by alcohol or a drug is a crime in Canada. Your vehicle does not have to be moving: you can be charged if you are impaired behind the wheel even though you have not started to drive.

Where impairment by a drug, or by a combination of alcohol and a drug, is possible, police can require a driver to:

provide breath samples
perform standardised field sobriety tests
