Canada is tightening the rules for young drivers in 2025. In a bold move to protect lives and promote road safety, the country is strictly enforcing zero-tolerance laws for underage and teen drivers. If you’re a teen or a parent of one, it’s essential to know what this means, how the law works, and what consequences can follow if it’s violated.
What Is the Zero-Tolerance Law?
The Zero-Tolerance Law means that drivers under a certain age must not have any alcohol, drugs, or cannabis in their system while operating a vehicle. Not even trace amounts.
This law is part of Canada’s broader road safety campaign to prevent accidents caused by impaired or reckless youth driving.
Who Is Affected? — Age Limits You Should Know
Here’s a quick look at the age groups targeted by this law:
| Driver Category | Age Range | Restrictions |
|---|---|---|
| Young/Teen Drivers | Under 21 years | Zero alcohol or drug tolerance |
| G1/G2 License Holders (Ontario) | Any age | Zero tolerance applies |
| Novice Drivers | Newly licensed | Strict sobriety rules enforced |
This law primarily targets young and inexperienced drivers, reinforcing the importance of being sober behind the wheel from the get-go.
Penalties for Breaking the Law
If a young driver is caught violating the zero-tolerance law, the penalties are serious — even for a first offense.
First Offense:
-
Immediate 3-day license suspension
-
$250 fine
-
Mandatory education or treatment program
Second Offense:
-
7-day license suspension
-
$350 fine
-
Enrollment in a remedial education course
Third Offense and Beyond:

30-day license suspension

Possible criminal charges
These strict measures are part of Canada’s effort to combat the rising number of Canada underage DUI cases.
Why These Laws Are Needed – A Closer Look
Here’s why Canada is doubling down on youth DUI laws in 2025:
-
Young drivers (ages 16–24) are more likely to be involved in fatal crashes.
-
Alcohol- or drug-impaired driving remains a leading cause of death among Canadian teens.
-
Enforcement sends a strong message: Zero tolerance equals zero chances.
2025 Updates: What’s New This Year?
As of 2025, provinces across Canada are aligning their rules more consistently, and some updates include:
-
Harsher roadside penalties for teen drivers under suspicion of DUI
-
Increased roadside testing for THC (cannabis) and alcohol in school zones and near nightclubs
