Understanding Canada’s Impaired Driving Laws

Posted on

Bill C-46 has strengthened Canada’s impaired driving laws. Police forces across Canada have recently stated that they will be increasingly vigilant enforcing DUI laws and Bill C-46 will assist them in this regard. Impaired driving has become a serious criminal offence. Parts one and two of Bill C-46 now:

  • Enforce new criminal offences for driving with a blood drug concentration that is at or above the legal blood drug concentration limit; and
  • Allows police officers to demand a driver to provide a sample of saliva, blood, or urine for drug screening.

The “Over 80” Rule

The “Over 80” rule means that for you to be charged with impaired driving, the police must establish that your blood alcohol content (BAC) was over 80 milligrams of alcohol in 100 ml. of blood. To show that you were driving impaired by alcohol or over the legal limit, the police will take a sample of your breath or blood to determine your BAC. To determine whether you were driving while impaired by a drug, they will take a sample of your saliva, urine or blood. Canadian law states that refusing to give a sample of same to the police is grounds for an arrest. The timing of a breath, blood, saliva or urine sample is critical and is governed by various provisions in the Criminal Code. If you or a loved have been arrested for driving under the influence of alcohol or drugs, contact a DUI lawyer to protect you from harsh sentencing.

Over 80 vs. Impaired Driving: Which Charge Applies to You?

When most people are pulled over for suspected impaired driving, they are very concerned about their blood alcohol level if they have been drinking. Almost no one thinks about what type of impaired driving charge they would receive if they are arrested.

Canadian laws on impaired driving are not all the same. If you are arrested for driving under the influence of alcohol or a drug, you may be charged with either impaired driving by alcohol or a drug or Over 80. Although you might have heard them used interchangeably, these charges are very different from one another. Even though you may be charged with both impaired driving and Over 80, you cannot be convicted of both. For example, if you are found guilty of both impaired driving and Over 80 at trial, the judge will enter a conviction for one of the charges and “stay” the other charge (a stay is similar to a withdrawal of a charge) based on the R. v.Kineapple principle.

  • An Impaired Driving Charge depends on how alcohol affected your ability to drive; you may be charged with impaired driving if you appear under the influence to the arresting police officer (i.e. poor driving, odour of alcohol, stumbling, slurred speech, difficulty standing or co-ordination problems etc.).
  • An Over 80 Charge depends on your blood alcohol content. If your blood alcohol is over the legal limit (0.08), you may be charged with Over 80, even if you do not appear to be under the influence of alcohol.
