Impaired Driving Charges in Canada

Being charged with impaired driving is one of the commonly prosecuted criminal offences in Canada. These charges carry mandatory minimum penalties, the real possibility of jail, and long-term consequences for your criminal record, employment, and ability to travel. Even a first offence can permanently change your future. If you are facing an impaired driving charge or investigation, it is critical to understand the criminal law and obtain legal advice immediately.

 

What the Law Says

Under the Criminal Code of Canada, it is a criminal offence to operate a motor vehicle:

  • While your ability is impaired by alcohol or drugs
  • With a blood-alcohol concentration (BAC) at or over 80 mg of alcohol in 100 mL of blood (0.08)
  • With a prohibited level of drugs in your body
  • While both alcohol and drugs are present
  • After failing or refusing to comply with a lawful breath or blood demand

Police have broad powers to demand roadside breath samples, including mandatory alcohol screening, which allows officers to require a sample even without suspicion of impairment.

Criminal impaired-driving offences include:

  • Impaired operation
  • “Over 80” / Excess blood-alcohol
  • Failure or refusal to provide a breath or blood sample
  • Drug-impaired driving
  • Impaired operation causing bodily harm or death

Impaired driving carries mandatory minimum criminal penalties:

First Offence

  • Minimum $1,000 fine
  • 1-year driving prohibition
  • Possible jail sentence

Second Offence

  • Minimum 30 days in jail
  • 2-year driving prohibition

Third or Subsequent Offence

  • Minimum 120 days in jail
  • 3-year driving prohibition

  • Impaired causing death: life imprisonment

Additional penalties often include:

  • Probation
  • Mandatory treatment or counselling
  • Long-term or lifetime driving prohibitions


Life Consequences of a Conviction

Beyond court-imposed penalties, an impaired driving conviction often results in:

  • A permanent criminal record
  • Major increases in insurance premiums or loss of insurability
  • Serious employment consequences, especially for professional drivers
  • Difficulty travelling internationally, including problems entering the United States
  • Long-term damage to personal and professional reputation
  • Impact on family life, housing, and financial stability

Impaired Driving FAQ

Can I be charged even if I “felt fine” to drive?

Yes. You can be charged based on breath or blood test results alone, even if you did not appear impaired. You can also be charged based solely on observed impairment without a breath reading.

What if I only refused because I was scared or confused?

A refusal or failure to provide a breath or blood sample is its own criminal offence and carries the same mandatory minimum penalties as impaired driving—often with even harsher treatment by the courts.

Can drug use lead to impaired driving charges?

Yes. Impairment by cannabis, prescription medication, or illegal drugs can all lead to criminal charges. Police may rely on roadside sobriety testing, drug screening, and blood samples.

Can impaired driving charges be fought?

Yes. Many impaired driving cases turn on:

  • Whether the police had the legal right to stop you
  • Whether the breath demand was lawful
  • Whether testing procedures were followed correctly
  • The reliability of the breath or blood sample
  • Charter violations involving detention, counsel rights, or search and seizure

Strong defences exist in appropriate cases, but they must be identified early.

Can I avoid jail on a first offence?

Often yes, but not always. While jail is not mandatory on a first offence, custody may be imposed where there are:

  • Very high blood-alcohol readings
  • Accidents or injuries
  • Dangerous driving behaviour
  • A prior criminal record



Will this affect my future even after the case is over?

Yes. A criminal record for impaired driving can affect employment, professional licensing, insurance, travel, and your ability to hold positions of trust for many years—or permanently.
