Cannabis and drug-impaired driving

Driving while impaired by any drug is treated as seriously as alcohol in Ontario. Novice and young drivers face a strict zero-tolerance rule.

Key facts to remember

  • G1, G2, and drivers aged 21 and under must have zero drugs in their system.
  • Cannabis impairs reaction time, judgement, and coordination behind the wheel.
  • Drug-impaired driving carries the same penalties as alcohol-impaired driving.
  • Even prescription or over-the-counter medicines can impair your driving.
  • Refusing a roadside drug test carries the same penalties as failing it.
