What to Do If You're Pulled Over for a DUI in Barrie

Getting pulled over on suspicion of impaired driving is one of the most stressful experiences a person can face. In Barrie and across Simcoe County, police conduct thousands of traffic stops each year — and the consequences of a conviction are severe. A criminal record, a driving prohibition, mandatory fines, and possible jail time are all on the table from the moment an officer signals you to pull over.

But a charge is not a conviction. The process from roadside stop to breathalyzer at the station is governed by strict legal requirements, and when police fail to follow them, the evidence they collect can be excluded. Understanding what happens at each stage — and what your rights are — is the first step toward protecting yourself.

This guide covers the entire DUI process in Barrie and Simcoe County, from the initial stop to the penalties you face, and the defences that can make the difference between a conviction and a dismissal.

What Happens During a DUI Stop in Barrie and Simcoe County

When a Barrie Police Service officer, OPP officer, or South Simcoe Police officer pulls you over, they are looking for indicators of impairment. These include the smell of alcohol, slurred speech, bloodshot eyes, fumbling with documents, or erratic driving prior to the stop.

The officer will ask you to produce your licence, registration, and insurance. You are legally required to provide these documents. The officer may also ask questions: “Where are you coming from?” “Have you had anything to drink tonight?” “How much did you have?”

Here is what you need to know: you must identify yourself and provide your documents, but you are not required to answer investigative questions. You have the right to remain silent. Politely declining to answer — “I’d prefer not to answer that” — is not obstruction. It is the exercise of a constitutional right. For a deeper discussion of what you must and must not do when police stop you, read our guide on your rights during a police stop.

If the officer forms a reasonable suspicion that you have alcohol in your body, they can make an Approved Screening Device (ASD) demand. This is where the roadside breath test comes in.

The Approved Screening Device: The Roadside Breath Test

The ASD is a handheld device the officer carries in their vehicle. It is not the same as the breathalyzer at the station — it is a preliminary screening tool. The officer will ask you to blow into it, and it will register one of three results: “pass,” “warn,” or “fail.”

You Must Comply With the ASD Demand

This is critical. Under section 320.27 of the Criminal Code, refusing to provide a breath sample into an ASD is a criminal offence carrying the same penalties as impaired driving itself. Many people mistakenly believe they can refuse the roadside test. You cannot — not without facing a separate criminal charge.

Even if you believe the stop is unlawful, even if you think you are sober, even if you have medical concerns about blowing — comply with the demand and raise your objections afterward through your lawyer. Refusal gives the Crown an easy conviction with no need to prove impairment at all.

The officer does not need a warrant or even reasonable and probable grounds to demand an ASD sample. Under the mandatory alcohol screening provisions that came into force in 2018, any officer who has a lawfully stopped vehicle can demand an ASD sample from the driver — no suspicion of alcohol required.

What Happens After You Blow “Fail”

If the ASD registers a “fail,” the officer now has reasonable and probable grounds to believe you are operating a motor vehicle with a blood alcohol concentration (BAC) over the legal limit. What follows is a rapid sequence of events:

Arrest and Rights to Counsel

The officer will arrest you and inform you of your right to retain and instruct counsel — your right to a lawyer. This is guaranteed by section 10(b) of the Canadian Charter of Rights and Freedoms. The officer must tell you that you have this right, and must give you a reasonable opportunity to exercise it.

In practice, this means the officer should tell you about the availability of duty counsel (a free lawyer available 24 hours a day) and allow you to call a lawyer of your choice or duty counsel before the breathalyzer test at the station. If they fail to do this — or if they rush the process, cut your call short, or deny you the opportunity entirely — it is a serious Charter violation that can result in the exclusion of breath results.

Transport to the Station

After the arrest, you will be transported to the nearest police station for the formal breathalyzer test. In Barrie, this is typically the Barrie Police Service headquarters on Ferndale Drive. If you are stopped on Highway 400 or elsewhere in Simcoe County by the OPP, you may be taken to the OPP detachment in Orillia or another nearby detachment.

Your vehicle will be towed or, if a sober passenger is present, the officer may allow them to drive it away. You are responsible for any towing and impound fees.

The Intoxilyzer at the Station: The “Real” Test

The roadside ASD is a screening tool. The Intoxilyzer (or other approved instrument) at the police station is the evidentiary breathalyzer — the test that produces the readings the Crown will use in court.

You will be required to provide two breath samples into the Intoxilyzer, taken at least 15 minutes apart. A qualified breath technician operates the machine and records the results. If both readings are over 80 milligrams of alcohol per 100 millilitres of blood (80 mg%), you will be charged with “over 80” under section 320.14(1)(b) of the Criminal Code.

The Intoxilyzer results are the centrepiece of the Crown’s case. The machine must be properly calibrated, the technician must be qualified, and the procedure must follow strict protocols. Any deviation can be challenged.

The Two-Hour Rule and “As Soon as Practicable”

Two critical timing requirements govern the breath testing process:

The two-hour rule: Under section 320.31(1)(a), the first breath sample must be taken within two hours of the time you were driving (or had care or control of the vehicle). If the police cannot get you to the station and obtain a sample within that window, the Crown loses the benefit of the statutory presumption that your BAC at the time of the test equals your BAC at the time of driving. This makes their case significantly harder to prove.

As soon as practicable: The Criminal Code also requires that breath samples be taken “as soon as practicable.” Even if the police get the sample within two hours, an unexplained delay — sitting in a parking lot, taking a long route to the station, waiting without reason at the detachment — can be challenged. The Crown must account for the time between your arrest and the breath test.

If either requirement is not met, an experienced criminal defence lawyer can argue to exclude the breath results or defeat the statutory presumption. These timing arguments are among the most effective defences in impaired driving cases.

RIDE Programs in Barrie and Simcoe County

Barrie Police and the OPP run RIDE (Reduce Impaired Driving Everywhere) checkpoints regularly, particularly during holiday weekends, summer long weekends, and the December holiday season. These checkpoints are set up at high-traffic locations throughout the city.

Common RIDE checkpoint locations in Barrie include:

• Bayfield Street (both north and south corridors)
• Dunlop Street (particularly near the downtown core)
• Highway 400 exit ramps (especially the Bayfield Street and Dunlop Street exits)
• Mapleview Drive (near commercial areas)
• Big Bay Point Road

RIDE stops operate under a different legal framework than ordinary traffic stops. Officers at a RIDE checkpoint can stop every vehicle passing through without any individualized suspicion. However, once stopped, your rights still apply. If the officer detects signs of impairment, the process described above — ASD demand, arrest, transport, Intoxilyzer — follows the same sequence.

If you are stopped at a RIDE checkpoint and have not been drinking, remain calm, provide your documents, and you will generally be on your way within a minute or two.

Common Defences to Impaired Driving Charges

A DUI charge in Ontario is not automatic conviction. There are numerous grounds on which impaired driving charges can be challenged. Here are the defences that arise most frequently:

Right to Counsel Violations

As discussed above, police must inform you of your right to a lawyer and provide a reasonable opportunity to exercise it. If they failed to do so — or if they proceeded with the breathalyzer before you had a meaningful consultation with counsel — the breath results may be excluded under section 24(2) of the Charter. Read more about how Charter violations lead to excluded evidence.

Delay Beyond Two Hours

If the first breath sample was not obtained within two hours of driving, the Crown cannot rely on the presumption that your BAC at the time of the test reflects your BAC at the time of driving. Without that presumption, the Crown must call toxicology evidence to establish your BAC at the relevant time — a much harder case to prove.

ASD Malfunction or Improper Operation

The ASD must be in proper working order and operated correctly. If the device was not calibrated, if the officer did not follow the manufacturer’s instructions, or if the device produced unreliable results, the grounds for arrest — and everything that followed — may be challenged.

Mouth Alcohol

Residual alcohol in the mouth from recent drinking, burping, vomiting, or even certain medications or mouthwash can produce a falsely elevated reading on both the ASD and the Intoxilyzer. Qualified breath technicians are supposed to observe you for a waiting period before testing to ensure mouth alcohol has dissipated. If they did not, the results are suspect.

Medical Conditions

Certain medical conditions — gastroesophageal reflux disease (GERD), diabetes, and other metabolic disorders — can affect breath test results. If you have a condition that may have influenced the readings, this is a defence your lawyer needs to know about immediately.

Improper Stop

If the initial traffic stop was not lawful — for example, the officer had no reason to pull you over and it was not a RIDE checkpoint — then everything that flowed from the stop, including the ASD demand and breath results, may be excluded as a product of an unlawful detention under section 9 of the Charter.

Drug Impaired Driving: A Different Process

Not all impaired driving cases involve alcohol. If the officer suspects impairment by drugs — cannabis, cocaine, opioids, prescription medications — the process is different.

There is no roadside breath test for drugs. Instead, the officer will rely on observations of impairment: bloodshot eyes, lack of coordination, unusual speech patterns, the smell of cannabis, or erratic driving. If the officer has reasonable grounds to believe you are impaired by a drug, they may demand that you submit to a Drug Recognition Expert (DRE) evaluation at the police station.

A DRE evaluation is an extensive, multi-step assessment that includes a physical examination, tests of coordination and vital signs, and an examination of your eyes. The DRE officer will form an opinion about whether you are impaired and, if so, by what category of drug. They may also demand a urine or blood sample.

DRE evaluations are highly technical and highly challengeable. The science behind them has been questioned in courts across Canada, and the procedures must be followed precisely. If you are facing a drug impaired driving charge, the defence strategy is often very different from an alcohol case.

Penalties for Impaired Driving in Ontario

The penalties for impaired driving convictions in Canada are set out in the Criminal Code and are mandatory minimums — meaning the judge has no discretion to impose a lesser sentence:

First Offence

• Mandatory minimum fine of $1,000
• Mandatory driving prohibition of one year (minimum)
• Criminal record
• Installation of an ignition interlock device may be required
• Potential for jail time, though custodial sentences on a first offence are uncommon absent aggravating factors

Second Offence

• Mandatory minimum 30 days in jail
• Mandatory driving prohibition of two years (minimum)
• Criminal record

Third and Subsequent Offences

• Mandatory minimum 120 days in jail
• Mandatory driving prohibition of three years (minimum)
• Criminal record

Over 80 vs. Impaired

There are two separate offences: operating a motor vehicle with a BAC over 80 mg% (commonly called “over 80”) and operating a motor vehicle while impaired by alcohol or a drug. You can be charged with both. The penalties are the same, but the defences differ. An “over 80” charge depends on the breath readings; an “impaired” charge depends on the officer’s observations of your driving and behaviour.

In many cases, the Crown proceeds on both charges. If the breath results are excluded, the Crown may still pursue the impaired charge based on observations alone.

Related Driving Offences

Impaired driving cases often involve related charges. If there was a collision, you may also face dangerous driving charges. If you left the scene, fail to remain is a separate and serious offence. These charges compound the penalties and the complexity of the defence.

Where Your Case Will Be Heard

If you were charged in Barrie, your case will proceed through the Barrie courthouse at 75 Mulcaster Street. Cases arising from other parts of Simcoe County may be heard at the Orillia courthouse or the Collingwood courthouse, depending on where the offence occurred.

Your first court appearance (typically a set-date appearance) will be scheduled on your release documents. You do not need to wait until that date to retain a lawyer — in fact, you should not.

What to Do Right Now If You Have Been Charged

If you have been charged with impaired driving or over 80 in Barrie or anywhere in Simcoe County, here is what you should do immediately:

1. Write down everything you remember. The details of the stop, what the officer said, what you said, how long each stage took, whether you were given access to a lawyer, and anything else you can recall. Do this as soon as possible while the memory is fresh.

2. Do not discuss your case with anyone other than your lawyer. Do not post on social media. Do not call the officer to explain yourself. Anything you say can be used against you.

3. Contact a criminal defence lawyer immediately. Impaired driving cases involve tight timelines and technical defences that require prompt attention. Disclosure must be reviewed, breath technician records must be obtained, and Charter arguments must be identified early.

4. Keep all documents. Your release papers, any conditions of release, your next court date — keep everything in a safe place and bring it to your first meeting with your lawyer.
