car-1531273_1920DUI in Ontario. Breathalyzer for Road test. Refusing to provide a breath, blood or urine sample

If you are stopped by the police while in your car, the police have the legal right to ask you to provide a number of different samples, including a roadside breath-screening sample, a breathalyzer sample, and a blood or urine sample. You have the right to consult a lawyer before the formal breathalyzer test at the police station and before a blood or urine sample is taken, but you do not have the right to refuse a roadside breath-screening test.

Although the police must have a good reason to believe you may have consumed alcohol or drugs before demanding a sample, you must generally always provide a sample upon request.
