Welcome to the London DUI & Impaired Driving Defence guide centre. Here you will find comprehensive resources covering everything from Over 80 charges to roadside licence suspensions, based on current Canadian federal and Ontario provincial regulations.
Facing an impaired driving charge in London, Ontario, is a stressful and life-altering experience. Under the Criminal Code of Canada, operating a vehicle while impaired is treated as a serious criminal offence that carries severe penalties, including hefty fines, mandatory driving prohibitions, and potential jail time. Even a first-time conviction can have a lasting impact on your employment, immigration status, and personal freedom.
In Ontario, impaired driving is prosecuted vigorously, and the consequences extend beyond the criminal courts. The province’s Highway Traffic Act enforces immediate roadside administrative penalties, such as vehicle impoundments and instant licence suspensions, before you even face a judge. Understanding the distinction between provincial administrative penalties and federal criminal charges is the first step in mounting an effective defence.
Criminal driving offences in this region are primarily heard at the Ontario Court of Justice, located within the London Courthouse on Dundas Street. For more complex cases, or those proceeding by indictment, the matter may be elevated to the Ontario Superior Court of Justice. Navigating these local courtrooms requires a deep understanding of procedural rules and the Crown Attorney’s approach to impaired driving prosecutions in Middlesex County.
The initial traffic stop and arrest are typically conducted by the London Police Service or the Middlesex County Ontario Provincial Police (OPP). A critical part of any impaired driving defence involves scrutinizing the actions of these local officers. This includes reviewing station camera footage from the London police headquarters, examining the calibration logs of local breathalyzer machines, and ensuring your Canadian Charter of Rights and Freedoms were not violated during the arrest.
Defending an impaired driving charge involves highly technical evidence, including toxicology reports, device calibration records, and constitutional law. Attempting to represent yourself against experienced Crown prosecutors is incredibly risky and can easily result in a permanent criminal record and maximum penalties. We strongly advise against trying to navigate the criminal justice system without a knowledgeable criminal defence lawyer.
A skilled lawyer can identify procedural errors, challenge the legality of the police stop, and negotiate with the Crown to potentially reduce or withdraw the charges. You can find a list of relevant local lawyers and government agencies at the top of this page to help you build a strong, evidence-based defence.
Impaired driving relates to your physical or mental inability to operate a vehicle safely due to alcohol or drugs, based on police observation. An “Over 80” charge means your blood alcohol concentration tested strictly above the legal limit, even if you showed no visible signs of impairment.
Yes. Under Ontario’s Highway Traffic Act, if you are charged with an Over 80 offence or refuse to provide a breath sample, you will receive an automatic 90-day Administrative Driver’s Licence Suspension (ADLS) at the roadside, long before your first court date.
Yes. Impaired driving is a hybrid offence in Canada. While most first-time offences are prosecuted as summary convictions, the Crown can choose to proceed by indictment for repeat offences or if the impaired driving caused bodily harm or death.
No. You do not have the right to consult legal counsel before complying with a demand for a roadside Approved Screening Device (ASD) test. However, you absolutely have the right to speak to a defence lawyer before taking the official evidentiary breath test at the police station.
For a first-time conviction on a basic impaired driving or Over 80 charge, the mandatory minimum penalty under the Criminal Code includes a $1,000 fine, a one-year federal driving prohibition, and a permanent criminal record.
Yes. A Canadian criminal record for impaired driving can significantly impact your ability to cross international borders. For example, entry into the United States is strictly at the discretion of border officials, and a conviction often results in being denied entry without a special waiver.
