Impaired driving in Canada covers alcohol, drugs (including cannabis), or a combination-plus situations where you may not even be moving (for example, “care or control”). This guide explains what counts, how criminal charges differ from provincial roadside penalties, what it can cost, and what to do next-clearly and in plain language.
Key takeaways
- Impaired driving is not only “over 0.08.” It can involve drugs, combined impairment, refusal, and “care or control.” 1
- You can face two tracks of consequences: Criminal Code charges (court) and separate provincial/territorial roadside penalties (licence/vehicle/fees). 1
- Roadside penalties can be immediate and expensive (suspension, towing, impound, programs, interlock), even if a criminal case is not completed. 4
- Insurance eligibility often becomes the biggest long-term issue: many insurers treat impaired driving as a serious conviction and may surcharge, restrict coverage, or decline. 9
- The safest rule is simple: if there is any doubt, do not drive. Arrange a ride and retrieve the vehicle later.

Quick answers
Is impaired driving only “over 0.08” in Canada?
No. The “over 0.08” level (80 mg alcohol per 100 mL of blood) matters, but it is not the only way you can face consequences. Impaired driving can involve alcohol, drugs (including cannabis), combined impairment, refusal to comply with testing, and even “care or control” in some situations. 1
Can you be penalized even without a criminal conviction?
In many provinces and territories, yes. Provincial/territorial laws can impose immediate roadside penalties (suspension, vehicle seizure/impound, fees, programs) that are separate from the court process. 4
What happens to your insurance after an impaired driving charge or conviction?
Expect eligibility to tighten and premiums to rise. Many insurers treat impaired driving as a serious conviction and may surcharge, restrict coverages (like collision/comp), require interlock conditions, or decline to renew. If standard insurers decline, a broker may need to place coverage through specialty/high-risk markets. 10
What should you do immediately if you think you may be impaired?
Don’t drive. Park safely, turn off the vehicle, and arrange a ride (designated driver, taxi/ride service, transit, or a friend). If police stop you, stay calm and follow instructions. Then document what happened as soon as you are safe.
Does cannabis count as impaired driving?
Yes. Canada has drug-impaired driving offences (including cannabis) and separate offences for combined alcohol-and-drug concentration. Testing and thresholds differ from alcohol-only situations. 1
What counts as impaired driving in Canada
Impaired driving generally means operating a motor vehicle (or having care or control of it) while your ability to drive is impaired by alcohol, a drug, or both. The Criminal Code is federal, but provinces and territories also set roadside tools and administrative penalties that can apply immediately. 1
Warning: “I feel fine” is not a reliable test
Impairment can show up as slower reaction time, poor judgment, and divided attention-sometimes before you feel “drunk” or “high.” If there’s any doubt, don’t drive.

Key terms: impaired, over-80, refusal, care or control
Impaired operation vs over-80 vs refusal
Canada’s federal framework includes multiple impaired driving offence types, including:
- Operation while impaired (alcohol, drugs, or both)
- Alcohol concentration offences (for example, at/over the legal limit within the relevant timeframe)
- Drug concentration offences (THC thresholds and certain other drugs)
- Combined alcohol-and-drug concentration offences
- Refusal / failure to comply with lawful demands for testing
The charge(s) laid in a case depend on the evidence and the situation. 1
Care or control: why parked cars can still matter
Many drivers assume impaired driving only applies if the vehicle is moving. In practice, risk can exist when you are impaired and still have the ability to set the vehicle in motion. If you are impaired, avoid the driver’s seat, keep keys out of reach, and arrange a safe ride or alternate shelter.
Alcohol and drug thresholds
Thresholds matter, but they are not the whole story. A driver can face consequences based on observed impairment, testing results, roadside screening, and provincial/territorial administrative rules.
| Category | Commonly discussed threshold | What it can trigger | Notes |
|---|---|---|---|
| Criminal alcohol limit | 80 mg alcohol per 100 mL blood (often called 0.08) | Criminal Code alcohol-concentration offence and court process | Canada also uses an “within 2 hours” framework for certain alcohol offences. 1 |
| Provincial “warn range” | Often 0.05 to 0.079 (varies) | Administrative roadside penalties (suspension, fees, programs) | Example thresholds and penalties differ by province (see below). 4 |
| Drug concentration offences | THC thresholds and other drugs (federal) | Criminal Code drug-concentration offences and court process | THC thresholds and combined offences are set federally. 1 |
| Refusal / failure to comply | Not a numeric threshold | Separate criminal offence, plus administrative roadside penalties | Refusal is treated seriously in law and in insurance underwriting. 1 |
Methodology note (numbers in this guide)
- Criminal Code thresholds and penalties are summarized from federal government guidance. 1
- Roadside penalty examples use official provincial sources where available (and can change). 4
- Out-of-pocket cost totals are shown as minimums or typical examples published by governments or public insurers (towing/impound and legal fees vary widely). 4
- Always confirm current amounts on your province/territory’s official page before you pay fees or book programs.
Criminal charges vs provincial roadside penalties
Impaired driving consequences often come from two directions:
- Criminal Code (federal): charges, court process, criminal penalties, and driving prohibitions. 1
- Provincial/territorial administrative law: immediate roadside suspensions, vehicle seizure/impound, fees, remedial programs, interlock conditions, and reinstatement steps that vary by jurisdiction. 4
Pro tip: separate “court outcome” from “licence reinstatement”
Even after a criminal case is resolved, you may still need separate steps to be legally licensed again (fees, programs, interlock, proof of insurance). Treat reinstatement like a checklist and confirm requirements with your licensing authority before driving.
Criminal Code penalties (Canada-wide baseline)
Criminal impaired driving penalties can be life-changing because they can include a criminal record, driving prohibitions, and escalating consequences for repeat offences. The federal government summarizes baseline penalties, including mandatory minimums for certain offences and higher maximums for more serious outcomes. 1
| Offence type (simplified) | Typical example | Mandatory minimum (examples) | Maximum penalty can reach |
|---|---|---|---|
| Impaired operation / over legal alcohol limit | Operating while impaired or at/over the alcohol limit | Commonly described minimums include a minimum fine for first offence and escalating jail minimums for subsequent offences (for certain offences). 1 | Can be much higher depending on the offence and circumstances. 1 |
| Refusal / failure to comply | Refusing lawful breath/blood demands | Treated seriously and can carry mandatory minimums similar to other impaired offences in federal summaries. 1 | Can be severe depending on prosecution route and facts. 1 |
| Impaired causing bodily harm | Collision causing injuries while impaired | Fact-dependent; sentencing increases with harm and aggravating factors | Higher maximum penalties than non-injury impaired offences. 1 |
| Impaired causing death | Fatal collision while impaired | Fact-dependent; treated among the most serious driving crimes | Can reach life imprisonment under the federal framework. 1 |
Screening demands and testing (high-level)
Depending on the situation, enforcement can involve roadside screening devices, evidentiary breath testing, evaluations related to drug impairment, and other investigative steps. Canada’s framework also includes mandatory alcohol screening in certain circumstances, meaning an approved screening device demand may be made even without individualized suspicion in permitted contexts. 1
Driving prohibitions and long-term consequences
Beyond fines or jail, a driving prohibition can affect employment, caregiving, and daily life. Even after a prohibition ends, provincial/territorial reinstatement steps (fees, programs, interlock, proof of insurance) can still apply.
Provincial and territorial roadside penalties: examples and why they differ
Roadside penalties vary because provinces/territories control driver licensing and highway safety rules. The goal is to reduce risk immediately (suspension and impound) and require education/treatment before full reinstatement.
| Jurisdiction | Example administrative category | What can happen (examples) | Published cost examples |
|---|---|---|---|
| Ontario | Warn range (commonly 0.05 to 0.079) and other roadside measures | Ontario publishes warn range consequences that can include immediate suspensions, monetary penalties, and required education/treatment programs (details can vary by driver type and occurrence). 2 | Ontario’s official page describes a 14-day immediate suspension, a $350 penalty, and a 16-hour program for a warn range consequence in its published guidance (confirm current amounts). 2 |
| British Columbia | Immediate Roadside Prohibition | Immediate suspension and vehicle impoundment can apply based on alcohol readings, with escalating consequences for longer prohibitions. 4 | B.C. publishes minimum total cost examples: about $600+ (3-day), $1,000+ (7-day), and $3,000+ (30-day), including fees like towing/impound and programs (varies). 4 |
| Alberta | Immediate Roadside Sanctions (WARN and FAIL) | Alberta publishes WARN penalties (0.05 to 0.079) and FAIL penalties (0.08+ or fail/refuse), including immediate suspensions, vehicle seizures, and fines that escalate with occurrences. 5 | Alberta publishes fines such as $300 (first WARN) and $1,000 (first FAIL), plus a victim fine surcharge (confirm current). 5 |
Where to confirm your exact provincial or territorial rules
Because amounts and program requirements can change, confirm your jurisdiction’s current rules before making decisions about reinstatement, budgeting, or insurance shopping.

Typical costs and fees: what adds up fast
Many people underestimate the total cost because they focus on fines and ignore towing/impound, reinstatement fees, programs, interlock, and insurance changes. Governments and public insurers publish examples that show how quickly costs can reach the thousands-sometimes within days-before any longer-term insurance impact.
| Cost category | What it can include | Published examples (selected) | What you should do |
|---|---|---|---|
| Towing and impound | Tow, storage, impound release fees | B.C. includes towing and impound in its published minimum cost examples for prohibitions. 4 | Ask the towing yard for daily storage fees and payment requirements immediately |
| Administrative penalties | Immediate roadside penalty payments and fees | Ontario publishes warn range penalty amounts in its guidance (confirm current). 2 | Confirm due dates, review/appeal windows, and proof-of-payment steps |
| Education or treatment programs | Mandatory education/treatment or remedial programs | Ontario’s warn range guidance includes required program hours in some cases. 2 | Register early and keep completion certificates in one folder |
| Ignition interlock | Installation, monthly fees, calibrations, removals | Some provinces link reinstatement to interlock participation, particularly after more serious administrative outcomes. 5 | Ask the licensing authority what proof and timeline are required before booking |
| Insurance impact | Higher premiums, reduced payment options, restricted coverages | Industry guidance notes that driving and insurance history (including convictions) affects premiums, and high-risk markets may be required. 9 | Shop early, keep quotes identical, and disclose consistently |
Reality check: insurance can be the largest long-term cost
Even if you can pay the immediate roadside penalties, insurance eligibility and premiums can remain difficult for years. Start shopping well before renewal and use a broker if standard insurers decline.
How impaired driving affects auto insurance in Canada
After an impaired driving event, the biggest shock is often not just price-it’s eligibility. Some insurers won’t write the risk in the standard market, especially if there is a serious conviction, multiple incidents, or a licence issue. Insurers also rate based on location, vehicle, and driving history, and convictions can materially change your premium and options. 9
Charge vs conviction: why timing matters
Insurance applications and renewals typically ask about convictions, and some also ask about suspensions or licence status. Even when a criminal charge is pending, an administrative suspension can affect whether you are legally allowed to drive-which matters for underwriting and coverage.
High-risk markets and Facility Association: what it is
If you cannot obtain coverage in the standard market, a broker may place coverage through specialty high-risk markets. In some provinces, Facility Association exists to help ensure eligible drivers can access auto insurance when they cannot obtain it through the standard market. 10
Insurance shopping checklist after an impaired event
- Confirm licence status (suspended, reinstated, conditions like interlock)
- Gather dates (suspension start/end, conviction date if applicable, court dates)
- Bring vehicle details (VIN, annual kilometres, use, parking)
- Keep coverage identical across quotes (liability limit, deductibles, collision/comp)
- Ask for assumptions in writing (licence status, interlock condition, listed drivers)
Pro tip: ask for decline reasons
If an insurer declines, ask (politely) whether it’s due to licence status, a specific conviction type, payment history, or vehicle/usage mismatch. Fix what is fixable (for example, reinstatement proof) before applying elsewhere.
What to do after a roadside stop or charge
Step 1: document what happened while it’s fresh
As soon as you are safe, write down a timeline: where you were, what you consumed (including timing), who you were with, where you drove, what police said, what tests were requested, and what paperwork you received. Keep all documents together.
Step 2: confirm your licence status before you drive
Confirm whether you are currently suspended and whether there are conditions (like interlock). If you cannot get a clear answer, treat it as “not reinstated.” Driving while suspended can create severe follow-on consequences.
Step 3: get legal advice early if you are charged
Impaired driving charges are serious, and outcomes depend on facts, testing, timelines, and prior history. A lawyer can explain disclosure, deadlines, and what conditions apply while the matter is pending.
Step 4: budget for immediate and near-term costs
Plan for towing/impound, administrative penalties, program costs, interlock, and transportation while you cannot drive. If your job depends on driving, speak to your employer early about temporary changes.
Ignition interlock, reinstatement, and getting back on the road
Interlock requirements are commonly tied to reinstatement in many jurisdictions, especially after more serious incidents or repeat occurrences. Some provinces allow earlier driving only with an interlock device installed; others require interlock for a set period after reinstatement. 5
A practical reinstatement checklist
- End date: confirm when your suspension/prohibition ends
- Fees: list every required fee and the payment method
- Programs: register, complete, and keep certificates
- Interlock: confirm if required, timing, and proof needed
- Insurance proof: confirm if proof is required for reinstatement
- Documents folder: keep everything together for renewal and reinstatement

What should I prepare before getting quotes after an impaired driving event?
Have driver details, vehicle info, and the exact dates of any suspension/prohibition or conviction. Keep coverage choices consistent across quotes so comparisons are meaningful.
Is it better to use a broker or buy direct?
Either can work. After an impaired event, many drivers do better with a broker who can access both standard and specialty markets if needed.
Can I be in trouble if I am sleeping in my car after drinking?
Risk can exist if you are impaired and still considered to have care or control of the vehicle. The safest approach is to avoid the driver’s seat, keep keys out of reach, and arrange alternate shelter or a ride.
Do roadside penalties affect insurance even without a conviction?
They can. Insurers may consider licence status, suspensions, and overall driving history when underwriting. Ask your broker/insurer how your specific situation is treated at renewal and keep responses in writing.
