De Boyrie Law

Refusing a breath test is treated just as seriously as failing one. Even hesitation or confusion at the roadside can result in a criminal charge.

Impaired Driving Lawyer

Failure to provide a breath sample is not a minor technicality—it’s a full criminal offence, often laid when police believe a person is trying to avoid a DUI. But these cases can be more complicated than they seem. 

  • Was the demand made properly?
  • Did the officer explain your rights?
  • Was there a valid reason for your inability to blow?

We examine the timing, language, and conduct of both parties to determine whether the charge can be challenged. If the process wasn’t followed by the book, the charge may not stand up in court.

Is refusing a breath test a criminal offence in Canada?

Yes. Refusing or failing to provide a breath sample upon lawful demand is a criminal offence that carries the same penalties as an impaired driving conviction.

If the demand wasn’t clearly explained or if you were confused due to language, medical issues, or stress, that may form the basis of a legal defence.
Possibly—but the law allows for defences based on a legitimate inability to comply. Medical documentation or video footage can help support your case.
A conviction leads to a criminal record, licence suspension, fines, and possible jail time. These penalties are identical to those for impaired driving.
