★★★★★ Excellent lawyer!!! Nicholas was a pleasure to deal with. He knows the DUI laws inside and out. Not only did he get my impaired driving and refuse breath test dropped but he cleared my name from the police database. I wouldn’t hesitate referring him to my friends and family if any of them were to be charged with DUI or related matters. Jacob C. Toronto (Google Reviews)

Refuse Breathalyzer FAQs
Q. Is refusing a breathalyzer in Ontario a criminal offence?
A. Yes. In Ontario, refusing a breathalyzer (or refusing to provide a breath sample after a lawful demand) is a Criminal Code offence often called “refusal” or “failure/refusal to comply.” It is treated very seriously, and in many cases the penalties can be similar to an impaired driving charge. The key issue is whether the police demand was lawful and whether you actually refused, which is why the facts and timing matter.
Q. What penalties can I face for refusing a breathalyzer in Ontario?
A. A refusal charge can trigger major consequences that can impact your record, your licence, and your future. Depending on the situation and your history, this may include a criminal record, significant fines, driving prohibitions, and other court-imposed outcomes. Because the penalties can be severe and long-lasting, it’s important to get legal information quickly and have the evidence reviewed carefully.
Q. What counts as “refusing” a breathalyzer test?
A. “Refusing” is not always just saying “no.” It can include conduct that police interpret as non-compliance, such as not providing an adequate sample when required, delaying without a valid reason, repeatedly failing to follow instructions, or refusing to go along with the testing process. These cases often turn on small details, so the exact words used, the timeline, and what officers recorded can make a major difference.
Q. Can a refusal charge be beaten in court?
A. It can be defendable, depending on the evidence. Common legal issues include whether the demand was made properly, whether the required legal steps were followed, whether you were given a real opportunity to comply, and whether there were communication, medical, or timing problems that affected what happened. A strong defence usually starts with a detailed review of disclosure, including officer notes, body-worn video (if any), and the demand wording and timing.
Q. What should I do if I’m charged with refusing a breathalyzer in Ontario?
A. Act quickly and get legal information from a qualified Ontario criminal defence professional, because early steps can protect your options. Keep notes of what happened while it’s fresh (times, locations, what was said, and who was present), and gather any documents you received. Then have the case assessed based on the actual evidence, because refusal cases are often won or lost on the details.
