First-Time DUI in Ontario? Here’s What You Need to Know

Being charged with impaired driving for the first time is a serious matter under Ontario and federal law. Even if you felt “fine to drive,” police in Ontario can demand a roadside breath sample without needing any signs of impairment. If you blow over 80 mg of alcohol per 100 mL of blood, or refuse to comply with testing, you can be charged under the Criminal Code.

A first-time conviction for impaired driving typically results in a mandatory minimum fine of $1,000, a one-year licence suspension, and mandatory participation in Ontario’s remedial measures program (Back on Track). Depending on the facts, you may also be required to install an ignition interlock device in your vehicle. In cases where there are aggravating factors—such as bodily harm, impaired driving with a minor, or very high blood-alcohol readings—jail time is possible.
