First-Offence Impaired Driving in Ontario: What Actually Happens
A first impaired-driving charge in Ontario is rarely a single event. It triggers an immediate roadside licence suspension, a 90-day administrative suspension, an interlock requirement and a Criminal Code charge prosecuted in provincial court. This guide explains what each step means, the realistic outcomes, and how to think about retaining counsel.
The charges and what they require to prove
Federal Criminal Code charges are typically: section 320.14(1)(a) impaired operation; 320.14(1)(b) operation with blood alcohol concentration at or over 80 mg/100 mL; and 320.15 refusal to provide a sample. The penalties are the same — mandatory minimum $1,000 fine on first offence and a one-year licence prohibition.
The Crown must prove care or control of a conveyance and either impairment or a BAC over the limit. 'Care or control' is broad — sitting in the driver's seat with the keys can suffice, even if the vehicle was never moved.
Licence suspensions — roadside, administrative and Criminal Code
Three suspensions stack: an immediate 90-day Administrative Driver's Licence Suspension under the Highway Traffic Act when the roadside test fails, a 7-day vehicle impoundment, and on conviction a federal one-year prohibition under the Criminal Code. The federal prohibition runs concurrently with the provincial suspension only after sentencing.
First offenders may apply for the Ignition Interlock Program after the first three months of the federal prohibition. The interlock device costs roughly $1,500 per year and must be installed by an approved vendor.
The court process and typical timeline
The matter proceeds in the Ontario Court of Justice. First appearance is set 4–6 weeks after the charge. Disclosure is obtained from the Crown, reviewed by defence counsel, and the matter is set for a judicial pretrial. Most files resolve at the pretrial stage. Trials are scheduled 6–12 months out.
Common pretrial issues: validity of the roadside demand, calibration of the approved screening device, delay between stop and breath test, and Charter section 8, 9 and 10(b) breaches. A successful Charter motion can exclude the breath results and end the case.
Realistic outcomes and the cost of conviction
On conviction: mandatory minimum $1,000 fine, federal one-year prohibition, mandatory Back on Track remedial program ($634), increased insurance for 3–6 years, and a criminal record. The total real-world cost of a first conviction commonly exceeds $20,000.
Reduced pleas — for example to a careless driving conviction under the Highway Traffic Act — avoid the criminal record and the federal prohibition but still trigger insurance consequences. Whether the Crown will accept such a plea depends on the facts, the BAC reading and the local Crown's policies.
Why counsel matters at the first appearance
An experienced criminal defence lawyer reviews disclosure before any plea discussion, identifies Charter issues, and engages the Crown about plea options. Self-represented accused are statistically more likely to plead to the full charge.
Most defence counsel offer free first consultations and flat fees for resolution work. The cost of competent representation is small compared to the cost of an avoidable criminal record.
