Impaired Driving Charges in Kitchener-Waterloo

It is a Criminal Code offence to operate a vehicle, or to have care or control of it, while your ability to drive is impaired to any degree by alcohol, drugs or both. Waterloo Regional Police and OPP officers use approved screening devices, field sobriety tests and Drug Recognition Expert evaluations, often followed by breath tests at a police station.

The charges

  • Impaired operation: based on the driving, the officer’s observations and physical coordination tests.
  • Over 80: a blood alcohol concentration of 80 mg per 100 mL of blood or more within two hours of driving.
  • Failing or refusing a demand: refusing a breath, blood or bodily fluid sample without a reasonable excuse. A first refusal carries a $2,000 minimum fine, double the $1,000 minimum for a first impaired or over 80 conviction.
  • Impaired driving causing bodily harm or death: the most serious charges, laid after a collision that injures or kills someone.

Roadside Penalties and Penalties on Conviction

Ontario’s current rules (in force since July 1, 2026) apply the moment you are charged:

  • 0.08 or over, a failed or refused test, or a poor Drug Recognition Expert evaluation: an immediate 90-day licence suspension, a 7-day vehicle impoundment and a $550 penalty, plus a remedial education or treatment program.
  • Warn range (0.05 to 0.079): 7 days and $250 the first time, then 14 days and $350, then 30 days, $450 and six months of ignition interlock.
  • Drivers 21 and under, G1/G2 and M1/M2 drivers, and commercial drivers: zero alcohol and zero drugs.

A Criminal Code conviction adds a minimum fine of $1,000 for a first offence ($1,500 or $2,000 for higher readings, and $2,000 for a refusal), a driving prohibition, and minimum jail of 30 days for a second offence and 120 days for a third. Ontario then suspends your licence for at least one year on a first conviction and requires an education or treatment program and at least a year of ignition interlock. Our guides cover Ontario licence suspensions, ignition interlock and getting your licence back.

How Kitchener-Waterloo Lawyers Defend These Cases

A Kitchener-Waterloo defence lawyer works through the Crown’s disclosure, including the police notes, the breath room video and the instrument records, looking for Charter breaches and procedural errors. Issues that often matter include:

  • Charter sections 8, 9 and 10: the reason for the stop, an arbitrary detention, the search, and any delay in reaching a lawyer.
  • The approved instrument: calibration and maintenance records and the qualified technician’s certification.
  • Timing: whether samples were taken within the Criminal Code time limits after driving.
  • Other explanations: medical conditions, injuries, fatigue or the conditions at the scene.

No lawyer can guarantee an outcome. A lawyer can explain which issues apply to your case before you decide how to plead.

The Kitchener Courthouse

Criminal charges from Kitchener, Waterloo and Cambridge are heard at the Waterloo Region courthouse, 85 Frederick Street, Kitchener. Your paperwork shows the date of your first appearance; a lawyer can often attend for you and request disclosure.

Frequently Asked Questions

Will an impaired driving conviction give me a criminal record?

Yes. A conviction creates a criminal record, which can affect employment, professional licensing and travel to the United States. A record suspension can only be applied for after a waiting period. A lawyer can explain the realistic outcomes for your case.

Can I drive during the 90-day suspension?

No. Driving while suspended is a separate offence with its own penalties, including impoundment and fines. See driving while suspended in Ontario.

What if I refuse the breath test at the police station?

Refusing a lawful demand without a reasonable excuse is a separate criminal offence. A first refusal carries a $2,000 minimum fine, higher than the $1,000 minimum for a first impaired or over 80 conviction, plus a driving prohibition and a record.

Do I have to blow at the roadside?

Yes. Since December 2018, police who lawfully stop you and have an approved screening device can demand a roadside breath sample without suspecting you were drinking.
