A persistent piece of bad advice circulates online. If a police officer asks you to blow, the story goes, you can just refuse. No reading, no evidence, no case. The reality is the opposite. Refusing a lawful breath demand in Canada is treated every bit as seriously as impaired driving itself, and in some ways it is harder to defend. For anyone in British Columbia who is facing a refusal charge, or who is considering what to do if the situation arises, the facts are worth knowing in advance.
The penalties are deliberately identical
A first-time refusal conviction carries the same mandatory minimum penalties as a first-time impaired driving conviction, a $2,000 fine and a one-year federal driving prohibition. A second offence within 10 years brings mandatory jail time. A third offence brings more. The Criminal Code was deliberately designed this way to ensure that refusing cannot be used as an escape from a likely impaired driving conviction.
In BC, a refusal also triggers administrative consequences. A 90-day Administrative Driving Prohibition can be issued. Vehicle impoundment can follow. ICBC consequences compound on top of the criminal ones. The stacking of provincial and federal penalties means a refusal conviction often produces a worse overall outcome than an impaired driving conviction, particularly for a first-time offender.
Mandatory alcohol screening changed the landscape in 2018
Before 2018, police needed a reasonable suspicion that a driver had alcohol in their body before they could demand a roadside breath sample. Since December 2018, officers who are lawfully engaged with a driver, for example during a traffic stop, can demand a breath sample into an approved screening device without any suspicion at all. This is called mandatory alcohol screening under section 320.27(2) of the Criminal Code.
Courts have largely upheld this power, though challenges continue. The practical consequence for drivers is clear. If you are lawfully stopped for any reason, even a burnt-out headlight, you can be required to blow. Refusing on the grounds that the officer had no reason to suspect you of drinking is not a valid defence.
What actually counts as refusing
Refusing is not limited to saying no. The offence captures a range of conduct, including:
- Failing to provide a suitable sample. This can happen when a driver does not blow hard enough, blows around the mouthpiece, or fails to complete the sample across multiple attempts without a valid medical explanation. Courts have repeatedly held that repeated failed attempts can constitute refusal.
- Prolonged delay or argument. Asking questions is fine. Refusing to comply until some condition is met is not. Officers are not required to stand at the side of the road indefinitely. Courts have found that lengthy delay with no legitimate purpose can amount to refusal.
- Claiming inability without evidence. A genuine medical inability to blow can be a defence. A bare claim of medical inability, without documentation or evidence, generally is not.
- Refusing the evidentiary test at the station. The roadside screening test is different from the evidentiary breath test at the police station. A driver who provides at the roadside but refuses at the station can be charged, and often is.
The narrow defences
Refusal cases can be fought. The most common defences include the following:
- The demand was unlawful. If the officer did not follow the proper procedure, did not read the correct demand, or did not have the authority to detain the driver at that moment, the demand itself is defective and the refusal charge cannot succeed.
- Right to counsel was denied. Section 10(b) of the Charter applies to the evidentiary breath test at the station. A driver who asks for a lawyer and is not given meaningful access before being required to provide samples has a strong Charter argument.
- Genuine medical inability. Asthma, serious respiratory conditions, dental issues affecting the mouthpiece seal, or other medical conditions can prevent a person from providing a valid sample. Proving this requires medical evidence, not just a statement.
- No intention to refuse. Confusion, language barriers, or misunderstanding of what was being demanded can sometimes support a defence that the accused never actually formed the intention required for the offence.
The hidden strategic problem with refusal cases
Refusal cases often look simple to the Crown because there is no breath reading to scrutinize. The Crown does not have to prove the accused’s blood alcohol concentration. It only has to prove the demand was valid and the accused failed to comply.
This simplicity cuts both ways. It means Crowns sometimes put less effort into the file than they would for a straightforward over-80 case. It means disclosure is often thinner. It means officers may not remember details as clearly because there was no breath test to anchor their memory. These features can create opportunities for the defence that a careful lawyer will find, but only if someone is looking.
What a lawyer specifically does on a refusal case
A defence lawyer handling a refusal charge does several things that cannot realistically be done without legal training.
A lawyer dissects the demand itself. The precise wording of the demand matters. The timing of it matters. Whether the driver was properly detained at the moment of the demand matters. Each of these elements is an entry point for a successful challenge.
A lawyer examines the right to counsel implementation. In refusal cases, this is frequently where the Crown’s case collapses. Rushing the caution, failing to call the lawyer the driver requested, or questioning the driver during the pause between arrest and contact with counsel are all common issues.
A lawyer works up medical defences properly. If there is a medical basis for inability to blow, it has to be established through documentation, often through a treating physician’s report or expert opinion. A bare assertion in cross-examination rarely succeeds. A lawyer knows what the threshold of proof looks like and what evidence is needed to meet it.
A lawyer negotiates outcomes that avoid mandatory minimums. In some refusal cases, a resolution to a Motor Vehicle Act offence such as driving without due care, or a guilty plea to a lesser charge, may be achievable. These resolutions avoid the criminal record and the one-year prohibition. Negotiating them requires credibility with the Crown and a clear sense of what the case is truly worth.
Frequently asked questions
I was cooperative until they said I had to blow. I panicked and said no. Is that a defence?
Panic alone is not a defence, but the circumstances around the refusal can matter. If you were confused, in medical distress, experiencing a mental health episode like a panic attack, not properly informed, or not given a chance to speak to a lawyer, those issues can be raised. A lawyer will want to hear exactly what happened in the minutes leading up to the refusal.
I have asthma and they said that was not an excuse. Were they right?
Not necessarily. Respiratory conditions can support a medical inability defence if there is proper medical evidence. The officer’s view at the roadside is not the final word. What matters is what you can establish in court.
I asked for my lawyer and they said I could call from the station. Is that legal?
It can be, but only if the station contact was provided promptly and meaningfully. Delays of any significant length, or attempts by police to question you in the interim, can be Charter violations. The specifics matter.
If the breath test at the station would have shown I was under the limit, does that help my refusal case?
Unfortunately, no. The refusal offence is independent of what a test would have shown. The question is whether you complied with the demand, not what the result would have been. This is exactly why refusal is not a strategy, even for people who believe they were not impaired.
Can I be charged with both refusal and impaired driving from the same incident?
You can be charged with both, though typically you will only be convicted of one. The Crown often proceeds with refusal when the breath evidence is unavailable, and with impaired driving or over-80 when it is. The two tracks sometimes run in parallel until it becomes clear which will be pursued.
This is my first offence. Can I avoid a criminal record?
Maybe. It depends on the facts, the Crown’s position, and what a lawyer can negotiate. Complete acquittal is possible where the Charter application succeeds. Resolution to a non-criminal Motor Vehicle Act offence is possible in some cases. Neither outcome is guaranteed, and neither is likely without a lawyer.
