Impaired Driving (DUI) Laws & Penalties in Canada by Province

Learn how Canadian law defines impaired driving and what penalties offending drivers face in Canada and across each province...

In today’s legal landscape, the definition of impaired driving has evolved, and you might be unfamiliar with what exactly impaired driving is. 

What is impaired driving / driving under the influence (DUI)?

If you look to Wikipedia, impaired driving is defined as: 

“having care or the control of a motor vehicle while the person's ability to operate the motor vehicle is impaired by alcohol or a drug.”

Seems straightforward, doesn’t it? Operating a passenger car, commercial vehicle, motorcycle, or any other machinery while under the influence is considered impaired driving. But what you might not be aware of is that certain penalties can be applied up to two hours after the act of driving.

The Canadian government sets the limit on how much is too much. And since Canada legalized the use of cannabis in 2018, it affected how impaired driving laws are applied in the country. 

What is the safe limit for driving after drinking?

The safe limit for consuming alcoholic beverages and then getting behind the wheel of a vehicle is… none. Even one drink can affect your ability to make the right decisions and snap judgements. 

The enforceable limits are different though, based on the concentration of alcohol in your bloodstream, or blood-alcohol concentration (BAC).

Canada’s Department of Justice establishes that the prohibited blood alcohol concentration is “80 milligrams (mg) or more of alcohol per 100 millilitres (ml) of blood.” That’s where the number ‘.08’ comes from. Provincial limits and penalties can be established at a lower level yet. 

Can I take cannabis and drive?

Pot, weed, marijuana, reefer, the herbal, maryjane – whatever name you call it, cannabis is still a drug. It’s been legalized in Canada but that doesn’t mean it’s free from consequences if you partake. Smoking or consuming cannabis and driving can land you in legal hot water, and a jail cell.

The primary psychoactive component in pot is THC. Consequences vary depending on the concentration in your blood. While it’s prohibited to drive with between two and five nanograms (ng) of THC per ml of blood, the offence is even more serious when it’s above 5ng per ml.

What about other drugs?

Clearly, the big factors for impaired driving are alcohol and cannabis. However, having any detectable amount of other illegal drugs in your system within two hours of driving is a big no-no. The exception is GHB, a party drug that’s naturally produced in human bodies in very small quantities – over 5mg of GHB per ml of blood is prohibited.

Canada’s penalties for impaired driving

Canada’s Department of Justice has established legal penalties for people convicted of impaired driving

  • If convicted of your first offence of alcohol impaired driving at or over .08 within two hours of driving, the mandatory minimum penalty is a $1,000 fine. Fines increase according to BAC with:
    • .08 to .119 dealt a $1,000 fine
    • .120 to .159 commanding a $1,500 fine, and;
    • blowing .160 or higher commanding a minimum $2,000 fine.
  • If convicted of your first offence of drug-impaired driving with more than 5ng of THC or any other prohibited drug in your system within two hours of driving, the mandatory minimum penalty is a $1,000 fine. 
  • The same minimum penalty applies if convicted of driving with more than 2.5ng of THC per ml and a BAC of .05 combined. 
  • For any of the above, a second conviction will net you a mandatory minimum 30 days in prison. 
  • And for a third conviction, offenders will receive a mandatory minimum penalty of 120 days in prison. 
  • The maximum penalty for the above charges is 10 years in prison.

Should you choose not to provide a sample when it’s been requested, there’s a minimum $2,000 fine. 

There are other penalties to consider too. A summary conviction for drug-impaired driving with 2ng of THC per ml of blood, up to 5ng, within two hours of getting behind the wheel will command a $1,000 fine. 

A conviction for impaired driving causing bodily harm has stiff but just penalties. A summary conviction carries a maximum two years in prison less a day while an indictment has a maximum prison term of 14 years.

And if convicted of impaired driving causing death, an indictment carries a maximum penalty of life in prison.

Impaired driving penalties in Alberta

Alberta’s impaired driving penalties follow the federal guidelines for impaired driving. However, additional sanctions may apply for a conviction, and they’ve been updated as of December 1, 2020.

  • For the first offence in a 10-year period, you’ll receive an immediate 90-day licence suspension and an additional one-year driving suspension where you must participate in an Ignition Interlock Program if you wish to drive again. Your vehicle will be seized for 30 days and you’ll need to participate in a ‘Planning Ahead’ course. A 20% victim fine surcharge will be added to the $1,000 fine.
  • For a second offence in a 10-year period, the same initial suspension occurs along with a 30-day vehicle seizure. You'll also receive a three-year license suspension, but you may be permitted to drive if you agree to an Ignition Interlock Program. You must complete an IMPACT Program, and a $2000 fine and 20% victim fine surcharge is levied.
  • For a subsequent conviction, the initial 90-day complete license suspension is applied, followed by a lifetime suspension unless you participate in the Ignition Interlock Program. You can only apply to have the interlock requirement removed after 10 years, but it isn’t guaranteed. The $2,000 fine and 30-day vehicle seizure rules also apply.

Impaired driving penalties in British Columbia

In addition to the federal penalties and standards, provincial laws in British Columbia are even more stringent. 

  • A BAC reading up to .049 may result in a 12-hour driving prohibition if you’re in the Graduated Licensing Program, and you’ll start your 24-month N license period over.

If your BAC is over .05: 

  • The first offence will result in an immediate three-day license seizure, a three-day vehicle impoundment, a $200 administrative penalty, and you’ll have to apply to have your license reinstated. 
  • The second offence within a five-year period has a penalty of a seven-day license seizure, seven-day vehicle impound, a $300 administrative penalty, and potentially a referral to the Responsible Driver Program. 
  • A third offence carries a 30-day license forfeiture, 30-day impoundment, $400 admin penalty, and possibly a referral for the Ignition Interlock Program. 

If your BAC is over .08:  

  • You may have to immediately surrender your license.
  • You could be issued a Notice of Driving Prohibition for 90 days, effective on the spot.
  • Your vehicle could be impounded for up to 90 days.
  • You may have to participate in the Responsible Driver Program and Ignition Interlock Program.

  • If convicted of impaired driving, penalties may include losing up to 15 points on the Driver Safety Rating scale, a hefty fine, possible prison time, a driving prohibition, mandatory license suspension, possible participation in the Ignition Interlock Program, and potential vehicle forfeiture.
  • If you have your license suspended two or more times within a 10-year time frame, a mandatory Impaired Driver Program assessment must be completed at the Addictions Foundation of Manitoba—at your expense.

Impaired driving penalties in New Brunswick

The Motor Vehicle Act in New Brunswick enforces stricter impaired driving laws than the federal standards. 

For drivers with a BAC between .05 and .079, a first offence nets a seven-day license suspension. A second offence lands a 15-day suspension while a third offence in five years results in a 30-day suspension, a license reinstatement fee, and mandatory involvement in a drinking driver education course.

Vehicles may also be impounded for:

  • Up to seven days if the BAC is within the warning range. 
  • 30 days on the first suspension with a BAC of .08 or higher.

For criminal convictions related to impaired driving in New Brunswick, a breathalyzer is mandatory for any vehicle the convicted person wishes to drive. The ignition interlock device is voluntary for short-term license suspensions.

Impaired driving penalties in Newfoundland and Labrador

Newfoundland and Labrador is one of the strictest provinces for impaired driving. 

Drivers under 22 years of age may not have a BAC higher than 0 while driving and convictions are possible for BAC levels higher than .049. 

Penalties include:
