What to Do If You’re Charged with DUI in Mississauga, Ontario

Charged with impaired driving in Mississauga? Here’s what actually happens after the arrest, how Ontario’s suspension timelines work, and the practical steps to take first.

Getting pulled over on the Queensway or Hurontario Street and ending up with an impaired driving charge is disorienting. One minute you’re driving home, the next you’re standing in a Peel Regional Police detachment being told your license is suspended on the spot. If this has just happened to you, or to someone you love, the first 24 to 72 hours matter more than most people realize. This guide walks through what actually happens after a DUI arrest in Mississauga, how Ontario’s suspension and court timelines work, and the practical steps worth taking before you do anything else. Many people in this situation start by talking to a Mississauga DUI lawyer simply to understand where they stand before making any decisions, and that first conversation is often less about hiring anyone and more about getting a clear picture of the process ahead.

It’s worth saying up front: this article is general information, not legal advice, and every case turns on its own facts. Nothing here should be read as a promise about how any particular case will turn out.

What Happens in the First Few Hours After Arrest

In Ontario, “impaired driving” covers a few related offences under the federal Criminal Code: driving while your ability is impaired to any degree by alcohol or drugs, and driving with a blood alcohol concentration at or above 80 milligrams per 100 millilitres of blood within two hours of driving. Refusing a lawful breath or drug test is also a criminal offence in its own right, and it’s treated roughly as seriously as the impaired driving charge itself.

Once you’re arrested, a fairly predictable sequence usually unfolds:

• Roadside screening. An officer who suspects impairment can demand a roadside breath sample using an approved screening device.
• Arrest and transport. A “fail” or refusal typically leads to arrest and transport to a police station for a formal breath or drug test on approved instruments.
• Administrative license suspension. Regardless of the criminal process, Ontario issues an immediate roadside license suspension the same day, separate from anything that happens in court later.
• Vehicle impoundment. A licence suspension for impaired driving is usually paired with a short vehicle impoundment, at your cost.
• Release conditions or a bail hearing. Most people are released with a promise to appear and conditions (such as not driving, or not consuming alcohol), though some are held for a bail hearing depending on the circumstances.
• A future court date. You’ll be given, or later mailed, a date to appear in the Ontario Court of Justice.

None of this determines guilt. An arrest and a roadside suspension are administrative and procedural steps, not a finding of fault, and the criminal charge is decided separately, later, in court.

Ontario’s License Suspension Timelines, Explained

One of the most confusing parts for people new to this is that there are actually two separate suspension tracks running at once: an immediate administrative one, and a longer one tied to a criminal conviction if it happens.

| Situation | Typical suspension length | Who imposes it | |—|—|—| | “Warn range” (BAC 0.05 to 0.079) | 3 to 30 days, escalating with repeat warnings | Ministry of Transportation, administrative | | “Fail” or refusal, first occurrence | 90-day administrative driving suspension | Ministry of Transportation, administrative | | Criminal conviction, first offence | Minimum 1-year suspension (varies with sentencing) | Criminal court, on conviction | | Criminal conviction, subsequent offence | Longer suspension, escalating with prior convictions | Criminal court, on conviction | | Young or novice drivers | Zero tolerance; any detectable alcohol can trigger a suspension | Ministry of Transportation, administrative |

The administrative suspension starts immediately and runs whether or not you’re ultimately convicted of anything. The criminal-conviction suspension only applies if the case ends in a conviction, and it’s on top of, not instead of, whatever administrative penalty already applied. Ignition interlock conditions are also common on reinstatement, meaning your vehicle needs a breath-testing device installed before you can drive again, for a set period.

Because these are two separate systems, it’s entirely possible to have your license back on the road (with an interlock) while the criminal matter is still working its way through the courts.

First Steps to Take After a Charge

Don’t drive on a suspended license. Driving while under suspension is a separate offence in Ontario and tends to make everything that follows harder, including bail conditions and sentencing if there’s a conviction.

A few practical things worth doing in the first week:

• Write down everything you remember about the stop and arrest while it’s fresh: where you were, why you were pulled over, what was said, and in what order.
• Keep every piece of paper the police gave you, including the notice of suspension and any impoundment or ticket paperwork.
• Note your court date and any release conditions in writing, and calendar them.
• Check whether your insurance requires notification of a charge or suspension; policies vary.
• Get legal advice before your first court appearance, not after.

Understanding the Criminal Court Process

Most DUI matters in the Mississauga area are heard at the Ontario Court of Justice location serving Peel Region. The general flow looks like this:

1. First appearance. Largely administrative; disclosure (the Crown’s evidence) is requested and a further date is set. 2. Reviewing disclosure. This includes the breath test results, officer notes, and any video, and it’s where potential issues with how the stop or test was conducted often surface. 3. Crown pre-trial and possible resolution discussions. Both sides discuss the case; this can lead to a range of outcomes depending on the evidence, none of which is predictable in advance. 4. Trial, if the matter proceeds that far. The Crown must prove the charge beyond a reasonable doubt.

Timelines vary significantly by court location and caseload, and can stretch across many months. Nobody can tell you in the first week exactly how long the process will take or how it will end. What a lawyer can generally do early on is help you understand the disclosure, flag procedural issues (for example, whether the roadside demand was made lawfully, or whether testing equipment was used and calibrated correctly), and explain the realistic range of what typically happens in similar cases.

Common Questions

Will I automatically lose my job or professional license? It depends heavily on your employer, your profession, and any regulatory body you belong to. Some professions have mandatory reporting requirements for criminal charges; others don’t. This is worth asking about specifically rather than assuming either way.

Can I get a restricted license to drive to work during the suspension? Ontario does not generally offer work-only or hardship licenses during an impaired driving suspension the way some other provinces or U.S. states do. Reinstatement conditions, including ignition interlock, apply on a set schedule instead.

Does refusing the breath test avoid a DUI charge? No. Refusing a lawful demand for a breath, blood, or drug sample is itself a criminal offence in Canada, generally treated with the same seriousness as the underlying impaired driving charge.

Do I need a lawyer for a first offence? There’s no legal requirement to have one, but given the two parallel processes (administrative suspension and criminal court) and the technical evidence involved (breath test calibration, timing, Charter issues around the stop itself), most people find it useful to at least get an initial consultation to understand their options.

Where to Get Help

If you’re facing charges and can’t afford private counsel, Legal Aid Ontario may be able to connect you with duty counsel or determine your eligibility for a legal aid certificate. Duty counsel are available at most Ontario courthouses on a walk-in basis for a first appearance, even before you’ve arranged anything else.

If you’re supporting someone affected by impaired driving, or want to understand the broader public safety picture, MADD Canada publishes plain-language resources on impaired driving law and its effects.

Whatever path you take, try not to make decisions about your case in the first 24 hours based on panic. The administrative suspension and impoundment happen automatically and quickly; the criminal process, by contrast, moves much more slowly and gives you time to get informed before anything is decided.
