The Legal Consequences of Impaired Driving in Calgary and How a Lawyer Can Assist

The Legal Consequences of Impaired Driving in Calgary and How a Lawyer Can Assist

Impaired driving is treated as a serious criminal offence in Calgary and across Alberta. Individuals found operating a motor vehicle under the influence of alcohol, drugs, or both can face significant legal and personal consequences. Understanding the laws under both federal and provincial legislation is essential for anyone facing charges—or trying to avoid them.

Criminal Code of Canada and Alberta’s Traffic Safety Act

In Canada, impaired driving is primarily governed by the Criminal Code, which applies uniformly across provinces. Under Section 320.14, it is a criminal offence to:

Operate a vehicle while your ability is impaired by alcohol or drugs

Have a blood alcohol concentration (BAC) at or over 80 mg of alcohol per 100 mL of blood (0.08)

Have a THC level of 5 nanograms or more per mL of blood

Operate with a combination of alcohol and cannabis over prescribed limits

Fail or refuse to comply with a lawful demand for breath, blood, or saliva samples

Alberta enforces additional penalties through the Traffic Safety Act, including licence suspensions and vehicle seizures, even for first-time offenders.

Key Definitions:

Alcohol-Impaired Driving: A driver operating a vehicle with a BAC at or above the legal limit (0.08), or showing signs of impairment.

Drug-Impaired Driving: Being under the influence of cannabis, prescription medications, or other controlled substances that impair driving ability.

Refusal to Comply: Refusing to provide a breath, blood, or saliva sample when demanded by law enforcement is considered a criminal offence and carries similar or greater penalties than impaired driving itself.

Immediate Roadside Sanctions (IRS) in Alberta

Since December 2020, Alberta has adopted an administrative model called the Immediate Roadside Sanctions (IRS) program. This approach allows police to issue penalties on the spot, often replacing criminal charges for first-time offences.

Penalties under IRS can include:

Immediate 15-month licence suspension (3-month full suspension + 12-month with ignition interlock)

Vehicle seizure for 30 days

Fines up to $2,000

Mandatory education or treatment programs (e.g., Planning Ahead or IMPACT)

For repeat offences or cases involving bodily harm or death, criminal charges are typically laid in addition to administrative penalties.

Common Scenarios Leading to Charges

Impaired driving charges in Calgary commonly arise from:

Checkstops: Random roadside sobriety checks conducted by Calgary Police Services, particularly during holidays or late-night hours.

Traffic Accidents: Any collision where the driver is suspected of being under the influence can lead to on-site testing and arrest.

Erratic or Dangerous Driving: Weaving between lanes, sudden stops, or excessively slow driving may prompt police to investigate for impairment.

911 Reports: Members of the public can report suspected impaired drivers, which police treat seriously and investigate promptly.

2. Immediate and Long-Term Legal Consequences

An impaired driving charge in Calgary triggers a mix of administrative and criminal consequences—some immediate, others long-lasting. Even a first-time offence can significantly impact your daily life, career, and future prospects. Here’s a breakdown of what you could face:

Immediate Consequences Under Alberta’s IRS Program

Under Alberta’s Immediate Roadside Sanctions (IRS), penalties can be imposed right at the roadside—even before a conviction in court:

90-Day Licence Suspension: You’ll lose your driving privileges immediately for 90 days, followed by 12 months where you may only drive with an ignition interlock device.

Vehicle Seizure and Impoundment: Your vehicle will be towed and impounded for 30 days at your expense.

Fines and Penalties: Fines for a first offence typically range from $1,000 to $2,000, not including administrative fees, towing, and storage.

Mandatory Courses: You must complete a Planning Ahead or IMPACT program, depending on your offence level.

Ignition Interlock Program: Required for drivers who want to regain limited driving privileges during the final 12 months of their suspension.

These penalties apply even if you are not formally charged criminally—making it critical to understand how Alberta’s administrative system works in tandem with the federal Criminal Code.

Criminal Penalties Upon Conviction

If your case proceeds to court and results in a conviction, the legal consequences escalate further:

Criminal Record: An impaired driving conviction results in a permanent criminal record, which can affect many aspects of your life.

Jail Time: For repeat offences or aggravating factors (like injury or high BAC), jail time is possible. A second offence carries a mandatory minimum 30-day sentence.

Probation Orders: You may be required to comply with a court-ordered probation plan, which can include counselling, community service, or regular check-ins.

Travel Restrictions: A criminal record for impaired driving often limits international travel, particularly to the United States, where even a single DUI can result in border denial.

How the Criminal Court Process Works in Calgary

First Appearance at the Calgary Courts Centre

Your first step will be attending a court appearance at the Calgary Courts Centre, located at 601 5th Street SW. This is a mandatory appearance where the charges are formally read, and you’re advised of your rights. You’re not required to enter a plea at this stage, but it’s crucial to attend—or risk a warrant being issued for your arrest.

For those with legal representation, your DUI lawyer may appear on your behalf for some early proceedings, especially if you’re charged with a summary offence.

Disclosure of Evidence and Plea Options

After your first appearance, the Crown prosecutor must disclose all evidence they intend to rely on. This includes:

Police reports

Breathalyzer or roadside testing results

Dashcam or bodycam footage

Witness statements

Your lawyer will review this disclosure to determine if there are legal grounds to challenge the stop, arrest, or the admissibility of the evidence. Based on the strength of the Crown’s case, you may be advised to:

Plead guilty and negotiate for a reduced penalty

Plead not guilty and proceed to trial

Resolution or Trial: What to Expect

Many impaired driving cases in Calgary are resolved without trial—often through plea negotiations with the Crown. This could result in:

Lesser charges

Reduced penalties

Entry into diversion or education programs (if eligible)

If the case proceeds to trial, your lawyer will present evidence, cross-examine witnesses, and challenge the Crown’s version of events. Impaired driving trials are heard by a judge alone for summary convictions, or by judge and jury for more serious indictable matters (though jury trials are rare in DUI cases).

Local Prosecution and Court Scheduling

Calgary impaired driving cases are typically heard in Provincial Court, which operates under Alberta’s jurisdiction but applies federal law through the Criminal Code. Due to the volume of cases, hearings and trials may be scheduled several weeks—or even months—apart.

Local prosecutors in Calgary take impaired driving very seriously, particularly when it involves high BAC levels, accidents, or refusal to provide samples. That’s why early legal representation can make a significant difference in the outcome of your case.

How a Calgary Impaired Driving Lawyer Can Assist

Reviewing the Arrest and Police Conduct

Your lawyer will start by thoroughly examining the circumstances surrounding your arrest, including:

How the traffic stop occurred

Whether the officer had reasonable grounds to demand a breath or saliva test

Whether proper procedures were followed during testing and detainment

Errors in police conduct or improper procedure can result in evidence being ruled inadmissible—possibly leading to reduced charges or a full dismissal.

Under the Canadian Charter of Rights and Freedoms, all individuals are entitled to legal protections—including:

The right to be free from unreasonable search and seizure

The right to be informed of your right to counsel

The right to retain and instruct a lawyer without delay

A Calgary impaired driving lawyer will assess whether your Charter rights were violated at any point during your interaction with law enforcement. If they were, your lawyer can bring a Charter application to exclude improperly obtained evidence, which may significantly weaken the Crown’s case.

Challenging Roadside Test Results

One of the most common defences in DUI cases involves challenging the reliability of testing devices such as the roadside breathalyzer or oral fluid drug screening equipment. A lawyer may:

Question whether the device was properly calibrated or maintained

Scrutinize how the sample was collected and stored

Cross-examine the technician or officer about testing procedures

If any doubts can be raised about the accuracy or fairness of the test, it can undermine the Crown’s case.

Representation in Plea Bargaining or Trial

If the evidence is strong, your lawyer can negotiate with the Crown for a reduced charge or sentence. This might include:

Resolving the matter through a plea deal

Arguing for a discharge (avoiding a permanent criminal record)

Requesting alternative sentencing such as probation or education programs

If your case proceeds to trial, your lawyer will represent you in court, presenting a comprehensive defence tailored to the facts and legal arguments specific to your situation.

Exploring All Possible Alternatives

In some circumstances, your lawyer may explore options like:

Conditional or absolute discharges

Referral to addiction treatment or driver education programs

Applying for early reinstatement of driving privileges through ignition interlock

These alternatives may mitigate the severity of your sentence or avoid a lasting criminal record—especially for first-time or low-level offences.

Why Early Legal Advice Is Critical

Early Intervention Preserves Evidence and Protects Rights

The hours and days following an arrest are crucial. A Calgary impaired driving lawyer can:

Ensure that dashcam footage, witness statements, or surveillance video are preserved before they are lost or deleted.

Advise you on what to say—and what not to say—to avoid self-incrimination.

Begin identifying procedural errors or Charter rights violations from the outset.

This early groundwork often forms the basis of a successful defence.

Navigating the IRS Appeal Process and Ignition Interlock Options

Under Alberta’s Immediate Roadside Sanctions (IRS) system, penalties are imposed before your case is even heard in court. A lawyer can:

File an appeal of the IRS decision to challenge the licence suspension or vehicle impoundment.

Help you apply for early reinstatement of your driving privileges with an ignition interlock device—which may be the only way to resume driving legally.

Having professional legal help ensures these time-sensitive applications are filed correctly and on time.

Mitigating the Consequences—Especially for First-Time Offenders

If this is your first impaired driving charge, a lawyer can help you avoid the worst-case scenario. This might include:

Negotiating for reduced penalties

Recommending enrolment in education or treatment programs to show rehabilitation

Seeking discharge sentencing or plea bargains to prevent a criminal record

Early legal advice helps identify the best path forward while there are still multiple resolution options on the table.

Peace of Mind from a Calgary-Based Legal Expert

Working with a lawyer who understands Calgary’s local courts, prosecutors, and procedures gives you a clear advantage. You gain:

Realistic expectations about your case timeline and outcome

Confidence knowing your case is in experienced hands

For many clients, the peace of mind alone is worth the consultation—especially when facing a criminal charge that could affect every part of their life.
