You blew a .085 on the roadside breath test, but you know you only had two beers with dinner, hours before you got behind the wheel. The officer says the number doesn’t lie, but you know how your body felt, and it wasn’t drunk. Now you’re sitting in a holding cell running through the whole night in your head: the beers, the drive, the traffic stop, trying to find the moment where things went wrong.
Alan Pearse understands how disorienting it feels to trust your own judgment and then have a number on a screen overrule it. He steps in to challenge that number, the stop that led to it, and every assumption built on top of it, so you’re not left carrying the weight of a test alone
What Should You Do If You’re Falsely Accused of a DUI in Toronto?
Comply with lawful directions, provide the identification the police require and ask to speak with a lawyer as soon as you are detained or arrested. Then contact a false DUI defence lawyer before you speak with police again or attend any scheduled court date. Ontario law gives officers broad power to demand breath samples during a traffic stop, but that power comes with rules about how and when it can be used, and a violation of those rules may provide grounds to challenge the demand or seek the exclusion of evidence.
Why Do False Impaired Driving Charges Happen?
A false accusation does not necessarily come from malice. It may result from equipment, procedure, and judgment calls that go wrong in ordinary, predictable ways.
Breath Testing Equipment Can Produce Misleading Readings
Screening devices and breathalyzers depend on calibration, maintenance, and proper use by the officer running the test. Mouth alcohol from a recent drink, mouthwash, or certain medical conditions can inflate a reading well above someone’s actual blood alcohol level while driving. Acid reflux, diabetes, and low-carb diets can all produce compounds that some devices misread as alcohol.
Officers Can Misjudge Signs of Impairment
Fatigue, a speech impediment, anxiety, or a medical episode like a seizure or diabetic reaction can look like intoxication during a quick roadside assessment. Bloodshot eyes and slurred words have plenty of causes that have nothing to do with drinking or drug use.
The Legal Timeline Matters
A blood alcohol concentration at or above 80 milligrams per 100 millilitres of blood within two hours after someone stopped driving is an offence, even if the breath or blood sample is collected later. Someone who has a drink on the front porch after getting home and then gets approached by police can register a reading that has nothing to do with their condition while the car was moving.
The criminal code provides a limited exception when the alcohol was consumed after driving, the person had no reasonable expectation that police would require a sample, and the test result is consistent with a blood alcohol concentration below the legal limit while driving.
What Powers Do Toronto Police Have at a Traffic Stop?
Officers running RIDE (Reduce Impaired Driving Everywhere) checkpoints across Toronto can demand a breath sample from any driver they’ve lawfully stopped, even without any suspicion of impairment. If an officer has reasonable grounds to suspect impairment, they can also demand physical coordination tests or samples for alcohol or drug screening. These powers aren’t unlimited: the stop has to be lawful, the demand has to be properly made, and the equipment has to be used in accordance with its approved procedure. A missed step at any point in that chain may provide grounds to challenge the demand or resulting evidence.
What Happens to Your Licence After an Arrest for a DUI?
Ontario runs two systems at once, and a false accusation can trigger both before a single word is said in a courtroom.
- Administrative suspension. A reading at or above .08, or a refusal to provide a sample, triggers a 90-day suspension on the spot, separate from any criminal charge that follows. For a first occurrence, Ontario also imposes a seven-day vehicle impoundment, an eight-hour education course, and a $550 administrative penalty.
- Warn-range suspension. A reading between .05 and .079 leads to an immediate roadside licence suspension, 7 days for a first occurrence, 14 days for a second, and 30 days for a third. Education, treatment, monetary penalties, and an ignition interlock requirement may also apply, depending on the number of prior occurrences.
- Criminal charge. Separately from either suspension, you can be charged under the Criminal Code. For an offence committed on or after July 1, 2026, a first conviction carries a licence suspension of at least one year, mandatory education or treatment, and an ignition interlock requirement of at least one year.
These administrative penalties can land immediately, and a conviction doesn’t end with suspension. It stays on a driving record for a minimum of 10 years, long after the immediate penalties are imposed on you, which is why it’s worth challenging a charge before it becomes a conviction rather than accepting one to make the process faster. This is also why an early call to a lawyer matters more than most people expect.
What Defences Apply When You Are Falsely Accused of Impaired Driving?
Potential defences to a wrongful charge of impaired driving may emerge once a lawyer properly reviews the evidence, including:
- Problems with the stop itself,
- Problems with the testing equipment or process,
- Problems with timing,
- Medical and physiological explanations,
- Charter rights violations during the arrest,
- Gaps in disclosure or required testing records,
- Unreliable observations from an untrained or inexperienced officer, and
- Witnesses who can speak to what happened before or after driving.
Which of these applies, if any, only becomes clear once your lawyer has actually reviewed the evidence in a specific case.
