Impaired driving lawyer in Calgary

An impaired driving stop in Alberta can lead to an immediate roadside sanction, a criminal charge, or both. The deadlines to respond are short, and the consequences reach your licence, your insurance, your job and, for non-citizens, your immigration status.

In Alberta, many first-time impaired driving cases are now handled through the provincial Immediate Roadside Sanctions program rather than in criminal court. Penalties can include licence suspension, vehicle seizure, fines and mandatory programs. These sanctions can be disputed through SafeRoads Alberta, but only within a short time after the stop.

In other cases, for example where there was a collision causing injury, a prior record, or a refusal, police may lay criminal charges under the Criminal Code. Those charges proceed through the courts.

The deadline to dispute a roadside sanction is short. It is measured in days, not weeks. Contact us immediately after the stop and keep every document the officer gave you.

Criminal impaired driving charges

  • Operating a vehicle while impaired by alcohol or a drug
  • Having a blood alcohol concentration of 80 mg or more within two hours of driving
  • Refusing or failing to comply with a demand for a breath or blood sample
  • Impaired driving causing bodily harm or death

How these cases are defended

We examine whether the stop and the demand were lawful, whether the testing was done properly and on time, whether your right to counsel was respected, and whether the disclosure supports the charge. Charter breaches and technical problems with the evidence can lead to evidence being excluded.

Immigration consequences

Impaired driving is treated as serious criminality under Canadian immigration law. A conviction can make a permanent resident or foreign national inadmissible to Canada. If you are not a citizen, tell us at the outset so we can consider the immigration consequences of every option.

What happens after an impaired driving stop

  1. Roadside

    The officer issues a sanction, lays a charge, or both, and gives you documents.

  2. Act quickly

    We review the documents and, if appropriate, request a review through SafeRoads Alberta within the deadline.

  3. Disclosure

    In criminal cases, we obtain and review the police evidence, video and test results.

  4. Resolution

    We challenge the evidence, negotiate, or defend the case at trial.

Frequently asked questions

Is an Alberta roadside sanction a criminal conviction?

No. Immediate Roadside Sanctions are provincial administrative penalties. They do not create a criminal record, but the penalties can be significant and the time to dispute them is short.

I refused to provide a sample. Is that better than failing?

No. Refusal is an offence in itself and generally carries consequences at least as serious as failing.

Will I lose my licence?

Licence consequences depend on whether the matter is handled as a roadside sanction or a criminal charge, and on your history. We explain what to expect in your case.
