Ontario’s Zero Tolerance Rule for G1 and G2 Drivers: What Changed in 2026

If you’re on a G1 or G2, Ontario’s zero tolerance rule is pretty simple. You can’t drive with any alcohol or drugs in your system. None at all. What a lot of students don’t realize is that the penalties got tougher on January 1, 2026, and the rule covers more people than they think.

I get asked about this in the car more than you’d expect. Usually it’s someone who had a drink at dinner and wants to know if they’re “fine” to drive home. On a G1 or G2, the answer is always no.

Who the zero tolerance rule covers

It applies to anyone 21 or younger, whatever licence they have. It also applies to anyone holding a G1 or G2, whatever their age.

That second group surprises people. I’ve had students in their 30s and 40s who just moved here and are working toward their G. They assumed the rule was for teenagers. It isn’t. If you’re on a G2 at 40, you’re held to the same standard as a 17 year old.

Cannabis counts too. Same rule, same penalties.

What’s different this year

Until the end of 2025, getting caught the first time meant your licence was suspended for 3 days at the roadside. Now it’s 7. The second time used to be 7 days and is now 14. A third time is 30 days.

You also have to take an education course after the first time now. Get caught again and it becomes a longer treatment program. A third time adds an ignition interlock condition to your licence for six months.

Old suspensions also follow you for longer than they used to. A mistake you make at 19 can still count against you years later.

What it really costs

The suspension is honestly the smallest part of it. You’ll pay a penalty, a reinstatement fee every time your licence gets suspended, and a fine on top of that if you’re convicted. The amounts change, so check ontario.ca for the current numbers.

A conviction can also mean another 30 or 90 days without a licence, or losing it altogether, depending on your age and licence.

And if you get suspended three times for breaking zero tolerance on a G1 or G2, your licence is cancelled. You go back to the start and redo every test.

Then insurance. A new driver with a suspension on their record pays a lot more, if they can get coverage at all. Whatever you saved by doing a BDE course is gone pretty quickly.

Where students get caught out

The one I worry about most is the morning after. You go to a party, sleep a few hours, and drive to class the next day feeling okay. Sleep doesn’t clear alcohol out of your body. Time does, and usually more of it than people think.

Then there’s the “it was only one” thinking. One drink isn’t zero, and zero is the rule.

Cannabis is similar. You might feel completely normal and still test positive.

Medication is worth mentioning too. This one applies to every driver, not just new ones. If your cold medicine or prescription can make you drowsy, it can affect your driving and you can be charged for it. Read the label before you get behind the wheel.

What about whoever’s sitting next to you

On a G1, the person in the passenger seat has to have a full G, at least four years of driving experience, and a blood alcohol level under 0.05. If your mom had a couple of glasses of wine at dinner, she might not legally be able to supervise you on the drive home. We go through all the G1 conditions in our G1 licence guide.

Questions students ask me

Does it stop when I turn 22?
Only if you’ve already got your full G. If you’re 22 and still on a G2, the rule still applies until you pass your G test.

Will a suspension mess up my road test?
You can’t drive while you’re suspended, and you really don’t want violations on your record going into a test. Keep it clean. If you want to know what else can end a test early, read our post on G2 automatic fails.

I drove for years back home. Does this apply to me?
Yes, if you’re on a G1 or G2 here. Our newcomer licence guide explains how your experience abroad can help you move through the system faster.

My advice

If you’ve had anything at all, leave the car. Take the TTC, get a ride, or crash on a friend’s couch. Getting a G licence takes months of work, and I’ve seen students lose it over one drink they thought didn’t matter.

When you’re ready to work toward your G2 or G with an instructor who’ll actually tell you this stuff, book a lesson with Rydbie Driving School.
