Defending Impaired Driving Charges: 80mg of Alcohol Within 100mL of Blood
Question: What should I do right after being charged with impaired driving in Orangeville, Ontario?
Answer: Right after an impaired driving charge, contact White Law PC, a criminal defence lawyer serving Orangeville and nearby communities, to review the stop, breath demand, testing timelines, and disclosure, and to advise you on immediate licence, bail, and court obligations. Avoid discussing the incident with police beyond identification, preserve any receipts, texts, and timeline details, and write down what happened while it’s fresh so your defence options can be assessed quickly.
Charged With Impaired Driving? Learn Your Rights, Risks, and Defence Options
An impaired driving charge is a serious criminal matter that can place your licence, finances, reputation, employment, insurance, and freedom at risk. Whether the allegation arose after a roadside stop, a breath demand, or an investigation following drinking and driving, the consequences can be immediate and stressful. Many people charged in these circumstances do not know what happens next, whether the police acted properly, or whether the evidence is actually strong enough to support a conviction. Early legal advice may be important. White Law PC assists people facing alcohol-related driving allegations with practical guidance, careful review of the evidence, and a defence strategy aimed at protecting their rights and reducing the damage that a criminal charge can cause.
Charged After Drinking and Driving?
Being charged does not automatically mean the case is straightforward or impossible to defend. Impaired driving prosecutions often involve technical evidence, strict police procedures, breath-testing rules, timelines, disclosure issues, and legal requirements that the prosecution must satisfy before a conviction can be obtained. What may seem simple at first can involve significant weaknesses once the evidence is closely reviewed. A prompt case assessment by White Law PC may help identify problems in the investigation, concerns about the testing process, and meaningful defence options.
The Law
The offence often described by the public as drunk driving, impaired driving, or being over the legal limit is governed by the impaired-operation provisions of the Criminal Code, R.S.C. 1985, c. C-46. In legal terms, one branch of the offence concerns operating, or having care or control of, a conveyance while having a prohibited blood alcohol concentration. The statutory wording addressing that allegation appears as follows:
Impaired operation
320.14 (1) Everyone commits an offence who
...
(b) subject to subsection (5), has, within two hours after ceasing to operate a conveyance, a blood alcohol concentration that is equal to or exceeds 80 mg of alcohol in 100 mL of blood;
...
Exception — alcohol
(a) they consumed alcohol after ceasing to operate the conveyance;
(b) after ceasing to operate the conveyance, they had no reasonable expectation that they would be required to provide a sample of breath or blood; and
(c) their alcohol consumption is consistent with their blood alcohol concentration as determined in accordance with subsection 320.31(1) or (2) and with their having had, at the time when they were operating the conveyance, a blood alcohol concentration that was less than 80 mg of alcohol in 100 mL of blood.
Although the law sets out the offence in precise terms, the real issue in many cases is whether the police investigation, roadside demand, breath testing, and record-keeping were all handled properly. These details matter because the prosecution must prove the charge in accordance with the law, not merely rely on accusation or assumption.
How Much Alcohol Can Lead To A Charge?
There is no universal number of drinks that safely tells a person they are below the legal limit. Blood alcohol concentration can vary significantly based on body weight, sex, metabolism, food intake, the amount and strength of the alcohol consumed, the speed of drinking, and the passage of time. A person may feel capable of driving and still face a criminal allegation after a breath test.
This is why many people are shocked when they are charged. They may have believed they were fine to drive, may have consumed what seemed like a moderate amount, or may have relied on rough assumptions about how quickly alcohol leaves the body. In reality, these situations can become highly technical very quickly, and what matters most is not guesswork after the fact, but whether the evidence can withstand legal scrutiny.
Drink Defined
For general reference, a “standard drink” is commonly described as:
- One twelve (12) ounce glass of beer at five (5%) percent alcohol by volume;
- One five (5) ounce glass of wine at twelve (12%) percent alcohol by volume; and
- One one and a half (1.5) ounce glass of spirits at forty (40%) percent alcohol by volume.
Even so, people should be cautious about relying on drink-counting as though it were precise legal protection. Mixed drinks may contain more alcohol than expected, pours are not always standard, and the body may continue absorbing alcohol after the last drink. Once a charge has been laid, the more important question becomes whether the police procedure and testing evidence are reliable, complete, and legally sufficient.
Why People Contact White Law PC
People charged with impaired driving often need urgent answers about their licence, their criminal exposure, their court process, their insurance risk, and whether the case against them can be challenged. They may also be worried about work, family responsibilities, professional obligations, travel, and the stigma attached to a criminal allegation. A timely consultation may help bring clarity to an otherwise overwhelming situation.
White Law PC may assist by reviewing the circumstances of the stop, the roadside screening process, the breath demands, the timing of events, the disclosure provided by the prosecution, and any legal or evidentiary issues that could affect the outcome. For many clients, that early review is the first meaningful step toward regaining control of the situation and making informed decisions about how to respond.
Potential Penalties
A conviction for an alcohol-related driving offence can carry serious consequences under the Criminal Code. Depending on the circumstances, the result may include fines, a criminal record, driving prohibitions, and possible jail exposure, with more severe outcomes in some cases. The statutory penalty framework includes the following:
Punishment
320.19 (1) Every person who commits an offence under subsection 320.14(1) or 320.15(1) is guilty of
(a) an indictable offence and liable to imprisonment for a term of not more than 10 years and to a minimum punishment of,
(i) for a first offence, a fine of $1,000,
(ii) for a second offence, imprisonment for a term of 30 days, and
(iii) for each subsequent offence, imprisonment for a term of 120 days; or
(b) an offence punishable on summary conviction and liable to a fine of not more than $5,000 or to imprisonment for a term of not more than two years less a day, or to both, and to a minimum punishment of,
(i) for a first offence, a fine of $1,000,
(ii) for a second offence, imprisonment for a term of 30 days, and
(iii) for each subsequent offence, imprisonment for a term of 120 days.
The consequences may also extend well beyond the sentence imposed by the court. A conviction can affect insurance premiums, employment opportunities, professional standing, border travel, and personal reputation for years to come. For many people, these collateral consequences are among the most damaging aspects of the case.
Take The Charge Seriously
An impaired driving allegation should not be treated like an ordinary traffic ticket or a problem that will simply resolve on its own. These cases are often technical, evidence-driven, and high-stakes. Timely legal advice may make a meaningful difference in understanding the charge, protecting your rights, and identifying the most effective path forward.
If you have been charged after drinking and driving, or accused of being over the legal limit, contacting White Law PC promptly may help you better understand your options, evaluate the strength of the case against you, and take informed steps to protect your future.
