Plain-Language Summary
Impaired Driving (Youth): The Department of Justice (DoJ) reports that many traffic accidents involving young drivers are caused by inexperience and poor judgment and when it comes to drugs or alcohol, there is no safe limit. It is a crime under s.320.14 (1) of the Criminal CodeA federal act codifying most criminal offences in Canada to have a blood alcohol concentration of .08 per cent or more, or to be impaired by narcotics. There are no mandatory penalties for offenders for impaired driving under the Youth Criminal Justice Act (YCJA). However, impaired driving could result in an automatic licence suspension, a fine or jail time. Impaired driving causing bodily harm or death is treated very seriously. As with any Criminal Code charge, a young personA person dealt with under the youth criminal justice system. is sentenced under the Youth Criminal Justice Act, not the adult maximum: if a youth sentence is imposed, the custody-and-supervision cap is generally two years, or three years where the adult offenceA criminal activity carries life imprisonment. An adult sentence is a rare, Crown-initiated exception the court must decide. While impaired driving is a Criminal Code charge, enforcement, apprehension, prosecution and the application of penalties fall within provincial and territorial authority. Many jurisdictions have a zero-tolerance policy for impaired driving for youth with penalties that differ in each province or territory.
What is Impaired Driving?
The DoJ reports (Impaired Driving Laws) that impaired driving is the leading criminal cause of death and injury in Canada. More than 69,000 impaired driving incidents were reported by the police, including almost 3,500 drug-impaired driving incidents in 2017.
According to MADD Canada (Youth and Impaired Driving,) traffic accidents continue to be teenagers' leading cause of death.
- Young people have the highest traffic death and injury per capita rates among all age groups and the highest death rate per kilometre driven among all drivers under 75 years of age.
- More 19-year-olds die or are seriously injured than any other age group.
- Motor vehicle crashes are the leading cause of death among those 16 to 25, and alcohol and/or drugs are a factor in 55 percent of those crashes.
- Those 16 to 25 made up 13.6 percent of the population in 2010 but resulted in almost 33.4 percent of the impaired-related traffic deaths.
The DoJ states that your brain needs to be alert and focused when driving, and even small amounts of a drug can affect your attention, judgment, motor skills, reaction time, decision-making skills, balance, and coordination.
If you operate a vehicle impaired by alcohol, a drug, or a combination of both, you can be charged. The Criminal Code creates two separate offences. The first, under s.320.14(1)(a), is operating a vehicle while your ability to drive is impaired to any degree by alcohol or a drug. This offence does not require a breath test and can be proved by other evidence of impairment. The second, under s.320.14(1)(b), applies if you have a blood alcohol concentration (BAC) of 80 mg of alcohol per 100 mL of blood within two hours of driving. You can be charged under either offence, or both.
With the introduction of legalized marijuana, the government enacted "stronger laws to deter and detect those who drive while impaired by alcohol and drugs, including cannabis," according to the Department of Justice.
The DoJ states the new law has three main elements to address drug-impaired driving:
- It creates new criminal offences of being at or over a prohibited blood drug concentration for certain impairing drugs, including THC and cocaine, within two hours of driving.
- It authorizes the police to use approved drug screening equipment, such as oral fluid drug screeners to detect the presence of impairing drugs in drivers.
- It strengthens the existing legal framework to enhance the investigation and prosecution of driving while impaired by a drug.
According to the 2014-15 Canadian Student Tobacco, Alcohol and Drugs Survey, which polled students in grades 7 to 12, five percent reported driving a vehicle within two hours of cannabis use, while 15 percent reported being a passenger in a vehicle driven by someone who had used cannabis in the previous two hours.
There are two prohibited levels for THC when operating a motor vehicle: between two and 5 nanograms of THC per ml of blood or the more serious offenceAn indictable offence with a maximum punishment of five years or more. of 5 ng or more of THC per ml of blood. It is also against the law to drive if you have any "detectable amount" of LSD, psilocybin, magic mushrooms, ketamine, PCP, cocaine, methamphetamine or 6-mam (an indication of heroin use) in your system, the DoJ states.
How Police Measure Impaired Driving
The federal government introduced legislation several years ago that makes it illegal to have a blood alcohol content level over the legal limit two hours after driving. Police do not need reasonable suspicion to demand a breath sample from you under the new law. Failure to comply will result in criminal charges that carry the same or greater penalties as driving while impaired.
Under the Criminal Code, you can be charged with impaired driving if you control any “conveyance,” including an automobile, snowmobile, all-terrain vehicle, a boat, aircraft or railway equipment. If police stop you, they can demand that you blow into a roadside screening device, provide an oral fluid sample measured by a screening device and/or participate in a series of standardized sobriety tests.
If you are suspected of being a drug-impaired driver and arrested, police can demand that you submit a blood sample to provide a more accurate measure of your level of impairmentA reduced ability to operate a vehicle due to alcohol or drug consumption. You can also be asked to complete a 12-step DRE evaluationA 12-step procedure to evaluate impairment. at the police station, which involves balance and attention tests. You may also be examined to check for indications of drug use, such as needle marks.
Penalties for Impaired Driving
Drivers of every age face harsh penalties for impaired driving. Three new criminal offences were created in 2018 for having specified levels of a drug in the blood within two hours of driving. If you are caught with between two and five ng of THC in your blood, that would be dealt with as a summary conviction criminal offence, punishable by a maximum fine of up to $1,000. If 5 ng or more of THC is detected in your blood, the DoJ document states your charge would be a hybrid offenceAn offence the Crown can proceed with summarily or by indictment., meaning that it can be prosecuted by indictment in serious cases or by summary conviction in lesser cases. If a blood test shows you have a combined THC and alcohol concentration of 50 mg of alcohol per 100 ml of blood, combined with a THC level greater than 2.5 ng per ml of blood, that would also be treated as a hybrid offence. According to s.320.19 of the Code, both hybrid offences would be punishable by mandatory penalties of $1,000 for a first offence and escalating penalties for repeat offenders. The minimum penalty for a second offence is 30 days in jail, with sentences of 120 days in custody imposed for a third or subsequent offence. The maximum penalty for the latter two convictions is two years less a day on summary conviction and ten years for indictable offences. If your BAC was between 120 and 159 mg of alcohol per 100 mL of blood, the mandatory minimum for a first offence rises to $1,500. If your BAC was 160 mg or more per 100 mL, the mandatory minimum is $2,000 (s.320.19(3)). Refusing to comply with a demand to provide a breath sample or a sample of a bodily substance is itself a criminal offence under s.320.15. It is a hybrid offence, punishable by a mandatory minimum fine of $2,000 for a first offence, up to 10 years imprisonment on indictment, or up to two years less a day on summary conviction. Since provinces and territories are responsible for their roadways, penalties may vary. Many jurisdictions have zero-tolerance policies for youth and impaired driving. In Ontario, for example, drivers age 21 or under and novice drivers of any age (with G1, G2, M1, or M2 licences) must not have any presence of alcohol or cannabis in their blood when behind the wheel. Penalties can include a fine, licence suspension and a fee for licence reinstatement. Your licence can also be cancelled, and your car can be impounded. In Alberta, if your licence is suspended in the final year of the Graduated Driver Licence phase, the one-year term starts following your licence reinstatement. A Youth Court judge can impose probation with alcohol counselling and/or community service. If you are convicted of impaired driving causing bodily harm under s.320.14(2), the penalties are set out in s.320.2 of the Code. The mandatory minimums are the same as for basic impaired driving: a $1,000 fine for a first offence, 30 days in jail for a second offence, and 120 days in jail for a third or subsequent offence. The maximum penalty is two years less a day in jail for a summary conviction or 14 years for an indictable offence. The charge of impaired driving causing death, under s.320.21, is an indictable offence with a maximum of life in prison. The same mandatory minimums apply: a $1,000 fine for a first offence, 30 days in jail for a second offence, and 120 days in jail for a third or subsequent offence.
Treated as Summary Conviction or Indictable Offence
When prosecuting a charge of impaired driving, the Crown can proceed as an indictable offenceA more serious type of Canadian criminal offence. or summary convictionLess-serious criminal offences. A conviction for an indictable offence carries more serious penalties.
Youth sentencing (Youth Criminal Justice Act)
This page is about a young person — someone aged 12 to 17 at the time of the offence — under the Youth Criminal Justice Act (YCJA).
A young person can be charged with this Criminal Code offence, but youth sentencing is different from adult sentencing. If the young person is found guilty, the youth justice court applies the Youth Criminal Justice Act.
Many less serious first-time youth matters may be handled through warnings, cautions, referrals, or extrajudicial measures instead of a formal court sentence. If the court does impose a youth sentence, the YCJA provides a range of options, including reprimands, discharges, probation, community service, restitution, and, in more serious cases, custody and supervision.
Custody is not the starting point for every youth case. The result depends on the charge, the facts, the young person’s history, the harm caused, the available programs, and the YCJA sentencing principles.
In rare cases, the Crown can ask for an adult sentence. That is not automatic. The court must apply the YCJA test before an adult sentence can be imposed.
For most offences, a custody-and-supervision order cannot exceed two years, or three years if the offence carries adult life imprisonment.
For an adult sentence, the court must be satisfied that the presumption of diminished moral blameworthiness has been rebutted and that a youth sentence would not be long enough to hold the young person accountable.
For a fuller explanation of how young people are sentenced, see How Youth Sentencing Works in Canada.
What the Crown Must Prove
To get a conviction, the Crown must prove every part of the offence beyond a reasonable doubt.
Section
Operation or care/control of a conveyance
The young person operated a conveyance (motor vehicle, vessel, aircraft, or railway equipment) or had care or control of it, within the meaning of Part VIII.1 of the Criminal Code (s. 320.14(1)).
Impairment to any degree, OR a prohibited concentration
EITHER the young person's ability to operate the conveyance was impaired to any degree by alcohol, a drug, or a combination of both (s.320.14(1)(a)); OR they had, within two hours of ceasing to operate, a blood alcohol concentration at or above 80 mg/100 mL (s.320.14(1)(b)); OR a blood drug concentration at or above the regulated threshold for that drug (s.320.14(1)(c)); OR a combined alcohol+drug concentration at or above the regulated combined threshold (s.320.14(1)(d)).
No applicable statutory exception
For the concentration-based branches (b)/(c)/(d), the Crown must be able to exclude the post-driving consumption exceptions in s.320.14(5)-(7) -- i.e. that any qualifying alcohol or drug consumption occurred before, not after, the young person ceased operating, or that they had reason to expect they would be tested.
Causation for the aggravated variants (bodily harm or death)
For the bodily-harm variant (s.320.14(2), punished under s.320.2): while operating the conveyance, the young person's conduct caused bodily harm to another person. For the causing-death variant (s.320.14(3), punished under s.320.21): the young person's conduct caused the death of another person.
Identity and time/place
The young person is the person who committed the act, the offence occurred at the time and place alleged, and the young person was 12 or older but under 18 at that time (YCJA s.2) -- a child under 12 cannot be charged with any offence (Criminal Code s.13).
A proof rule (a presumption) is a rule about evidence. It does not mean the person is automatically guilty. It means the court may treat one fact as evidence of another fact unless there is evidence pointing the other way.
Possible Defences and Legal Issues
Impaired Driving (Youth) — s.320.14
Impaired driving under section 320.14 can be charged more than one way: that alcohol or a drug impaired the person’s ability to drive, or that their blood alcohol or blood drug concentration was over the legal limit within two hours of driving.
The Criminal Code has narrow exceptions for the over-the-limit charges. For example, section 320.14(5) says “No person commits an offence under paragraph (1)(b) if” the person consumed the alcohol only after they stopped driving, had no reasonable expectation at that time that they would have to provide a sample, and their alcohol consumption is consistent with a blood alcohol concentration below the legal limit while driving. Subsections (6) and (7) set out matching exceptions for the drug-concentration and combined alcohol-and-drug charges. These exceptions do not apply to the basic charge of driving while impaired.
Drinking or drug use after driving is not a general defence. The Crown still has to prove the parts of the offence, including impairment or the concentration level, driving, timing, and that testing procedures were followed correctly. These issues depend on the facts.
This note deals with the federal Criminal Code charge. Provincial licence suspensions, vehicle impoundment, and other driving consequences may have separate rules.
Because this is a youth page, the Youth Criminal Justice Act may affect the court process and sentence. The Criminal Code offence and the section 320.14 exceptions are still the starting point for the charge.
