Driving Offences in Canada

Impaired driving and ‘over 80’ charges, commonly known as “DUI” offences, describe driving charges involving alcohol or drugs.

In Canada, it is illegal to drive or have “care or control” of a vehicle or other conveyance (such as a boat) when your ability to drive has been impacted by alcohol or drugs. Even if alcohol consumption does not affect your driving you may be charged if the concentration of alcohol in your blood is equal or greater to 80mgs of alcohol in 100mls of blood.

If drugs do not affect your ability to drive, the detection of certain substances in your blood at any level can result in a charge. If you are consuming or have consumed marijuana, 5 nanograms of THC in 100mls of blood may result in a charge.

To ensure compliance with impaired driving investigations, it is also illegal to fail or refuse to provide a sample of your breath, blood, or urine when a police officer makes a demand.

London Impaired Driving Lawyers Defend You Against Conviction

Because driving is a regulated activity in Canada, the federal and provincial governments have enacted legislation giving police and other State authorities expanded powers in dealing with you while you are driving or operating other conveyances.

The Criminal Code is regularly amended, and other laws have been created to give police more power to stop vehicles and investigate you. Prosecutors have been given evidentiary shortcuts in trials, and you now have fewer defences and opportunities to challenge the evidence against you when you are charged with impaired driving or “over 80” offences.

These expanded State powers and evidentiary shortcuts are not limitless, and while they can be challenging, defences are still available to you if you are charged with impaired driving and related offences.

Even while driving, our Charter of Rights and Freedoms guarantees you protection against unreasonable detentions, searches of your vehicle, and seizure of your breath, urine, or blood for analysis by police.

Our London Impaired Driving Lawyers Work Harder to Protect You

We work to hold police accountable at trial to ensure they do not misuse or abuse their expanded powers. We work with experts to challenge unreliable testing procedures and devices to protect you from the easier path to conviction given to prosecutors.

We ensure there has been compliance with the legally required procedures and standards, and we bring applications to exclude illegally obtained evidence from being used against you.

The government is working hard to make things more difficult for you if you have been charged with impaired driving related offences, but we work harder to uphold Canada’s constitutional values and protect you from illegal police action.

About Snow Lawyers Professional Corporation

We are trial lawyers. We work late nights and we bring complicated applications to challenge prosecutions.

When we are in trial, it consumes us—we are single-minded in our pursuit of success and protecting you against the immense power of the government.

We protect your privacy, your family, your freedom, and your livelihood. We protect you from prosecutions that can be driven by political objectives, not the pursuit of justice.

We protect you from dishonest police and civilian witnesses, and illegal police conduct.

How much will my case cost?

The cost of each case depends on the nature and complexity of the charges you are facing. The cost of your defence will also depend on if you have a trial or resolve the case in another manner, and the experience level of your lawyer.

Do you charge by the hour or offer flat rate fees?

At Snow Lawyers we charge a flat fee for each stage of your proceedings. This offers a high degree of certainty when you are planning to pay for your defence, and ensures there are no surprises. We also feel it is important you don’t worry your lawyer is going to charge you for every second when you need to communicate important information about your case.

Do you offer payment plans?

We understand that being charged with a criminal offence is an unexpected and unpleasant surprise. If you are not able to pay for your defence all at once, we will work with you to structure a payment plan that allows you to make payments over time.
