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 offence, 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 you refuse to comply with a demand for bodily samples, you could be fined $2,000.
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's Licence phase, the one-year term starts following your licence's reinstatement.
A Youth Court judge can impose probation with alcohol counselling and/or community service.
Under s.320.2 of the Code, if you are charged with impaired driving causing bodily harm, you face a maximum penalty of two years less a day in jail for a summary conviction or a maximum of 14 years for an indictable offence. The charge of impaired driving causing death, s.320.21, is always an indictable offence, with a maximum of life in prison.
