Being pulled over and later charged with impaired driving can feel disorienting, especially in the first hours and days afterward. This guide walks through how these charges typically come about, the general path a case follows once it reaches the court system, and how the criminal process relates to, but is separate from, provincial licensing consequences. It is written as a companion to our shorter charge-profile page and focuses on the practical experience of moving through a case rather than repeating the specific legal definitions and penalty ranges found there.
How These Charges Typically Arise
Impaired driving charges usually begin with some form of police contact on the road: a routine traffic stop, a spot-check or roadside checkpoint, or a call about a collision or erratic driving. Once an officer forms the view that testing is appropriate, the situation moves from an ordinary traffic interaction into a criminal investigation. This shift can happen quickly, and it is one reason people often describe the experience as confusing in the moment, since the legal significance of what is happening may not be obvious as it unfolds.
A charge can also follow a collision investigation that happens well after the fact, particularly where injuries are involved and police continue gathering evidence over subsequent days or weeks. In those situations, a person may not be arrested at the roadside at all, but instead learn of a charge somewhat later, once an investigation has progressed.
Roadside Stops and Testing
At the roadside, an officer may request a breath sample using an approved screening device. Since significant changes to the Criminal Code took effect in December 2018, police in Canada generally have broader authority to request this kind of sample from a lawfully stopped driver. The specifics of when and how that authority can be used are legally detailed, and they are covered in more depth on our dedicated guide to refusing a breath sample, which distinguishes lawful demands from situations where a refusal charge may arise instead.
If the roadside result or other observations (such as an officer's assessment of speech, coordination, or driving pattern) suggest impairment, a person is often taken to a police station for further testing on an evidentiary breath instrument, or in some cases blood testing or drug recognition evaluation. Throughout this process, the right to speak with a lawyer generally applies at defined points, and understanding that right in advance can make a stressful situation somewhat easier to navigate.
Important: Exactly what testing occurs, in what order, and under what legal authority varies by the specific facts of a stop. General descriptions like this one cannot substitute for a review of the actual police notes and any recordings in a specific case, which is precisely the kind of review a lawyer carries out once disclosure is available.
What Generally Happens Right After a Stop
After testing, a person may be released with a document setting out a future court date and any interim conditions, such as a temporary restriction on driving. In some cases, particularly where there are aggravating circumstances or an existing record, a person may instead be held for a bail hearing. Which path applies depends heavily on individual circumstances.
It is common, though not universal, for an administrative roadside licence suspension to take effect at the same time, under Ontario's own driving legislation. That process is discussed next, since it is easy to conflate with the criminal charge itself, even though the two proceed independently.
Criminal Charges vs. Provincial Licence Suspensions
One of the most important things to understand about an impaired driving charge is that it actually involves two separate legal systems working alongside each other. The criminal charge itself is laid under the Criminal Code, which is federal law that applies uniformly across Canada; you can review the relevant provisions directly through the Department of Justice's consolidated Criminal Code. At the same time, Ontario's own provincial legislation allows for administrative driver's licence suspensions that are separate from, and can begin before, any outcome in the criminal case.
This distinction matters a great deal in practice. A provincial suspension is generally an administrative measure tied to a roadside result or a charge itself, handled outside the criminal court process, while the criminal case proceeds through the courts toward its own resolution, whether that is a withdrawal, a plea, or a trial. The rules governing provincial suspensions, how long they last, and how they interact with a later criminal court outcome, are detailed and can change, and they are genuinely complex enough that this guide will not attempt to summarize specific durations or thresholds here. Anyone affected by a provincial suspension should confirm current requirements directly with a lawyer or with Ontario's own licensing authorities, since relying on a general article for specifics in this area carries real risk of relying on outdated or inapplicable information.
Caution: Do not assume that resolving, winning, or having the criminal charge withdrawn automatically undoes a provincial licence suspension, or vice versa. These two tracks are governed by different rules and, in some circumstances, different timelines. Confirm the status of both directly with a lawyer rather than assuming one outcome controls the other.
The General Path a Case Follows
Once a charge is laid, the case generally moves through the same broad framework used for most criminal matters in Ontario. It typically begins with a first court appearance, followed by the request and review of disclosure, the evidence and information the Crown has gathered, which for an impaired driving case often includes police notes, breath test records or certificates, and any available video footage from a cruiser or booking area. From there, a case may proceed toward resolution discussions or, if it is not resolved earlier, toward a trial.
The Ontario Court of Justice, where the large majority of these matters are heard, publishes general procedural information on its own website, which can be a useful starting point for understanding how a local courthouse operates; see the Ontario Courts website for court-specific information. Because impaired driving is charged so frequently, courthouses across the province see a steady volume of these cases, and the pace at which a specific matter moves can depend heavily on the courthouse, the Crown's office, and how much disclosure needs to be gathered and reviewed.
For the specific Criminal Code definitions, classification, and penalty ranges that apply to this offence, see our Impaired Driving charge page, which focuses on the legal elements of section 320.14 rather than the procedural experience covered here. Where a charge involves a collision causing serious injury, it is also worth reviewing our guide to dangerous driving charges, since the two offences sometimes arise from overlapping facts.
What Can Affect How a Case Unfolds
In general terms, several factors tend to shape how an impaired driving case develops, though none of them predicts a specific result on their own. These commonly include the strength and reliability of the testing evidence, whether the legal requirements for the roadside or station demand were properly followed, whether there is a prior related record, and whether the driving caused any injury or property damage. Courts and Crown attorneys generally weigh the totality of the circumstances rather than any single factor in isolation.
Because mandatory minimum penalties apply to this offence, Crown attorneys in Ontario often take a firm general approach to resolution discussions, though the specific facts of a case, including any genuine issues with how evidence was gathered or documented, remain the most common basis for contesting a charge. Independent legal research services such as CanLII allow the public to read publicly available Canadian court decisions, which can offer useful background context, though interpreting how past decisions might apply to a specific case is something a lawyer is best placed to do.
What to Do Next
If you are facing an impaired driving charge, a few general steps are worth considering early on, recognizing that a lawyer's advice tailored to your specific facts will always be more useful than general guidance:
- Write down what you remember about the stop and any testing while the details are still fresh, including approximate times.
- Keep any paperwork the police gave you, including any notice of a provincial licence suspension, in one place.
- Confirm your next court date and make sure you understand any interim conditions that apply to you.
- Speak with a lawyer before deciding how to plead or discussing the incident in detail with anyone other than your own counsel.
- Ask your lawyer specifically about how the provincial licensing side of your matter is proceeding, since it is easy to overlook while focused on the criminal case.
The federal Department of Justice also publishes general public legal information about impaired driving law in Canada, which can be a useful starting point; see justice.gc.ca for official federal resources. None of this replaces individualized legal advice, but it can help orient someone who is new to the process.
Frequently Asked Questions
Will my licence be suspended immediately after an impaired driving charge?
This is common in many cases, since Ontario's provincial rules generally allow for an administrative roadside suspension separate from the criminal charge, but exactly when this applies and for how long can vary and is genuinely complex. Confirm your specific situation with a lawyer or Ontario's licensing authorities rather than assuming a general timeline applies.
Does a provincial licence suspension mean I will also be convicted?
No. A provincial administrative suspension and a criminal conviction are separate outcomes governed by separate processes. It is possible for one to occur without the other, depending on the circumstances.
How long does an impaired driving case typically take to resolve?
This varies considerably depending on the courthouse, the complexity of the evidence, and whether the matter proceeds to trial. There is no single timeline that applies to every case.
Can I keep driving while my case is before the court?
This depends on whether a provincial suspension applies, any interim release conditions set in the criminal case, and your specific circumstances. This is an important question to raise directly with a lawyer as early as possible.
Is it worth speaking with a lawyer even if I think the evidence against me is strong?
Generally yes. A lawyer can review disclosure for procedural issues, confirm whether legal requirements were properly followed, and advise on realistic options, all of which are difficult to assess without a legal background.
What if I was not actually driving when police approached me?
Impaired driving law can, in some circumstances, apply to being in care or control of a vehicle without it being in motion. Whether that applies to a specific situation depends heavily on the facts and is worth discussing directly with a lawyer.
Will this charge show up on a background check right away?
This depends on the type of check and when it is conducted relative to the case. General information about how criminal records work is available on our criminal records overview, though specific questions are best directed to a lawyer.
