When Experience Matters

Do you Live in Oakville and Have Been Charged with Impaired Driving?

Like all of Ontario, a DUI is a Criminal Offence in Oakville

Impaired driving is usually thought of as a minor offence by most people owing to the fact that so many individuals are charged with impaired driving each year. This commonly held belief is wrong because the severity of an offence is not based on how common it is but rather on how bad the consequences are for the people involved. As such, impaired driving, driving while high, driving under the influence, and drunk driving are classified under criminal offence because they can result in the loss of life and/or property. This also explains why individuals who are convicted for impaired driving in Oakville are given harsh penalties.


The consequences for impaired driving in Oakville go beyond paying fines and losing one’s driving license. A first-time conviction can mean higher insurance premiums on top of fees and fines. Offenders are also required to enrol and pay for impaired driving education programs and post-license suspension ignition interlock programs. Consecutive convictions are dealt with harsher consequences which include jail time. For people whose cases come with aggravating factors such as reckless driving, high blood alcohol level, and having an accident that resulted in the loss of property and/or life, they are given tougher penalties or sentencing. Note that a conviction for a criminal offence in Oakville can follow an individual throughout life and can have a huge impact on getting jobs in the future as well as buying a home, starting a business, and travelling outside of Canada.

So You’ve Been Charged with Driving Under the Influence (DUI)

What Are the Possible Impaired Driving Charges in Oakville?

Care & Control

Care & Control is a charge of impaired driving for an individual who is not the person driving the vehicle but is the person who has care and control of the vehicle while impaired. This is made when the arresting officer has reason to believe that the same person will have the same control when they are operating the vehicle.

Impaired Driving

An impaired driving charge in Oakville is made by the officer even without a blood alcohol test reading or a breathalyzer test if the officer believes that the person driving the vehicle is unable to drive safely. The officer must be able to prove the impairment of the driver such as evidence that the driver is showing unsteady gait, slurred speech, erratic driver, and lack of motor coordination. The prosecutor and officer must also be able to prove that these symptoms are related to drug use or alcohol ingestion.

Over 80

An Over 80 charge is made when the driver’s BAC is over 80mg per 100ml of blood as measured by an approved screening device, an example of which is a breathalyzer. Prior to testing the driver, the arresting officer must have reasonable and probable grounds that the driver’s ability to operate a vehicle is impaired due to alcohol ingestion or drug use.

Refusing a Blood Sample or Refusing a Breathalyzer

Refusing a Blood Sample or Refusing a Breathalyzer are charges for impaired driving in Oakville that are made when the driver is not cooperative with regards to providing a sample or if the sample provided is not enough to be used for the investigation.

DUI Law/Impaired Driving FAQS

Sections 320.11 to 320.4 of the Canadian Criminal Code covers the impaired driving laws in Oakville. Charges for DUI vary based on the circumstances leading to the arrest. The charges include:

    • Care and Control
    • Driving Under the Influence
    • Failure to Provide a Breath Sample
    • Impaired Driving
    • Over 80 Mgs BAC Reading

The prosecutor’s strategies for establishing guilt for the above charges vary but the penalties for a guilty finding are the same.

A person is arrested for DUI in Canada after the police officer has established reasonable suspicion that the person may be impaired while driving based on observations and roadside testing. The person will be brought to the police station for further testing and evaluation. Note that refusing to provide fluid samples or perform a test carries the same penalties as a DUI conviction.

The minimum penalties for those convicted of a DUI charge in Oakville or anywhere in Canada are as follows:

First Offence

    • $1,000 fine for a BAC of 80 to 119, $1,500 fine for a BAC of 120-159, and $2,000 fine for a BAC of 160 or more
    • 12-month driving prohibition
    • $2,000 mandatory fine for anyone with first refusal to provide a breath sample

Second offence

    • 24-month driving prohibition
    • 30 days of jail time

Third and Subsequent Offences

    • 36-month driving prohibition
    • 120 days of jail time

All transportation offences carry a maximum penalty of 10 years on indictment and 24 months less a day on summary conviction.

A drinking and driving charge is treated as a serious criminal offence in the Canadian Criminal Code and is met with the following consequences:

    • Criminal record
    • Expensive administrative fees
    • Impounding of vehicle
    • Increased insurance premiums
    • Mandatory attendance to education and/or treatment program
    • Possible ignition interlock requirements if and when driving privileges are restored



A DUI charge of Over 80 means that the accused registered a blood alcohol concentration of more than 80 milligrams per 100 millilitres of blood as measured by a screening device. The Criminal Code of Canada lays down specific requirements for the collection of blood and breath screening samples under Section 320.14(1). According to the Canadian Criminal Code, screening devices must be handled by qualified technicians for the reading to be admissible in court as evidence. The testing must be completed within a window of 2 hours starting from the time when the accused was initially detained by the arresting officer. Furthermore, individual samples should only be taken at intervals of 15 minutes. Because of the technical aspects and strict legal requirements of testing an accused’s BAC, an accused will need the services of a highly skilled DUI lawyer to challenge the results as well as identify  possible errors during the procedure.

Having a criminal defence lawyer with expertise in defending DUI charges is the first step in effectively beating a DUI charge. Each DUI charge that goes to trial carries key differences that require a skilled DUI lawyer to defend effectively. An experienced DUI lawyer has a repertoire of defences to form the best strategy to defend a DUI charge based on specific circumstances and charges. An Over 80 charge will not have the same defence as a Care and Control charge and will require a different strategy.

The defence strategies that are most often used for a DUI charge are the following:

  • Challenging if the accused’s Charter-protected rights were respected
  • Challenging the arresting officer’s interpretation of care and control
  • Challenging the validity of the drug screening or the validity of the BAC screening device
  • Raising legal reasons if the accused failed to provide a sample, refused a roadside screening, or rejected a breathalyzer test
  • Questioning the lawfulness of the police procedure and the original police detainment

The professional and legal fees charged by a DUI lawyer varies based on the amount of time spent to defend the accused and the complexity of the case. Although the actual court time spent for hearings of DUI charges are usually short, the DUI lawyer will spend a lot of time sorting through details to create an effective defence strategy. More so, defending some cases can take a lot of time due to assorted motions which will require additional time for case preparation, research, interviewing witnesses, and more.

A skilled DUI lawyer may be able to resolve the charges in favour of the accused by negotiating a settlement with the prosecution and/or without having to go through a trial. If the DUI lawyer can recognize a significant flaw in the Crown’s case before the trial, that information can be used by the DUI lawyer to convince the Crown to drop charges.

Generally speaking, the Crown prosecutor will reject dismissals except in instances where the recognized flaw is so obvious and cannot be ignored. In most cases, the Crown will opt to drop the DUI charges for the acceptance of a guilty plea for a lesser offence such as careless driving. An experienced DUI lawyer will know how to work with the case details to achieve the most favourable outcome for the accused while making the other party think that they are not at a disadvantage.

As mentioned in response to other DUI FAQs, Crown prosecutors will usually not dismiss charges unless with a compelling reason to do so. The possible reasons for a DUI charge to be dismissed with the help of a DUI lawyer are if the accused’s charter rights were not protected, the screening methods used were impaired, the arrest was questionable, there were mistakes during the stop and detention, and other similar circumstances wherein the right processes were not followed.

The Crown prosecutor is likely to drop the DUI charge if their case is so flawed that it is impossible for them to win during the trial. If the DUI lawyer knows for certain that the case is flawed but was not able to convince the Crown prosecutor to drop the case, then the DUI lawyer can use the flaw as a key defence strategy during the trial and possibly achieve a not guilty sentence.

A DUI conviction means having to pay higher auto insurance in most cases. More so, insurance companies may choose not to renew insurance or reject an insurance application for someone guilty of a DUI. If you can find an insurance firm willing to take you as a client, be prepared to be charged minimum of twice the standard rate.

Since impaired driving offences are classified under serious criminality in Canada, Canadian immigration law Bill C-46, Part 1 says that it is grounds for revocation of permanent resident status and could lead to deportation.

Canadian law does allow for the expungement or suspension of a DUI criminal record. This action seals the record from public view while law enforcement can still access the data. Application for a record suspension is possible 5 years after a guilty plea or a conviction and may need the services of a DUI lawyer.
