Refusal to Provide a Breath Sample

Breath Test Refusal: frequently asked questions

Can you refuse a breathalyzer in Ontario?

You can physically decline, but refusing a lawful demand without a reasonable excuse is a criminal offence under section 320.15 of the Criminal Code. A refusal conviction carries a mandatory minimum fine of $2,000 on a first offence, a driving prohibition and a criminal record. At the roadside you also face an immediate 90-day licence suspension and a 7-day vehicle impoundment, even before any court date.

What counts as a refusal to provide a breath sample?

A refusal is not limited to saying no. Police can lay the charge if you ignore instructions, delay without reason, or appear to blow without providing a suitable sample. That last situation is usually called failing to provide a sample, but the consequences are the same. Whether your conduct was truly a refusal, and whether you understood the demand, are often central questions at trial.

Is refusing a breath test worse than failing it?

In several ways, yes. The minimum fine for a first refusal conviction is $2,000, which matches the minimum for the highest blood alcohol readings and is double the standard $1,000 minimum for a first over 80 conviction. Jail minimums for repeat offences and the driving prohibitions are the same. A refusal also gives the Crown no breath reading to test, so the case turns on the demand and your response.

Do I have the right to call a lawyer before a roadside breath test?

Generally, no. Courts have accepted that roadside screening is meant to be quick, so there is no right to consult a lawyer before providing a roadside sample into an approved screening device. The right to counsel without delay under section 10(b) of the Charter applies after arrest, before the station tests on the Intoxilyzer. If police did not respect that right, evidence may be excluded.

What is a reasonable excuse for refusing a breath test?

The Criminal Code allows a defence where a person had a reasonable excuse for not complying with a demand. Whether an excuse is reasonable depends on the facts, such as a genuine medical or physical inability to provide a sample. Simply believing you were sober, or wanting to speak to a lawyer first at the roadside, is not enough. The strength of any excuse needs careful review of the evidence.
