What Are the Mandatory Minimum Sentences for Impaired Driving in Markham?

4 Jun 2026 4 min read No comments DUI & Impaired Driving Defence Markham

Under federal law, a first-time impaired driving conviction in Markham results in a mandatory minimum $1,000 CAD fine and a 1-year driving prohibition. A second offence mandates at least 30 days in jail, and a third offence carries a minimum of 120 days in custody.

Being charged with impaired driving or operating a vehicle “Over 80” (having a blood alcohol concentration over 80 mg) is one of the most stressful experiences a driver can face. While many people think of these offences as simple traffic tickets, they are actually serious crimes prosecuted under the federal Criminal Code of Canada. Unlike other criminal charges where a judge has wide discretion for leniency, impaired driving comes with harsh mandatory minimum penalties.

If you are arrested by York Regional Police, it is vital to understand what is legally at stake before you step foot inside the Newmarket courthouse. A conviction fundamentally alters your life, stripping away your driving privileges and imposing massive financial burdens. This guide breaks down the legal process, the staggering costs associated with a conviction in Ontario as of May 2026, and how the mandatory minimums operate.

Step-by-Step Process in the Ontario Justice System

Facing impaired driving charges involves battling two separate systems simultaneously: the provincial Ministry of Transportation (MTO) for your licence, and the federal criminal justice system for your freedom.

Step 1: Immediate Administrative Penalties

The punishment begins before you even see a judge. The moment you are charged in Markham, York Regional Police issue a 90-day Administrative Driver’s Licence Suspension (ADLS). Your vehicle is also immediately impounded for 7 days at your expense. 🚫 You have no right to drive during these initial 90 days, regardless of the hardship it causes.

Step 2: The First Court Appearance

Your first appearance will be at the Ontario Court of Justice in Newmarket. You do not testify on this date; it is simply an administrative step where your defence lawyer collects your “disclosure.” This package contains the police notes, breathalyzer calibration logs, and video footage from the station.

Step 3: Crown Pre-Trial and Negotiation

Your lawyer will meet with the Crown attorney to discuss the case. If there are severe constitutional breaches-such as an officer denying your right to call a lawyer without delay-the Crown might agree to drop the criminal charges and allow you to plead guilty to a lesser provincial traffic offence, like Careless Driving, which carries no criminal record.

Step 4: Sentencing and Mandatory Minimums

If you plead guilty to the criminal charge or are found guilty after a trial, the judge is legally forced to impose the mandatory minimum sentence. While a judge can give you a higher penalty, they are strictly prohibited by federal law from going below the established minimums.

How Much Does a Conviction Cost?

The financial ripple effect of an impaired driving conviction is devastating. A first-time conviction can easily drain tens of thousands of dollars from your savings over a span of three to five years.

  • Mandatory Fine: The minimum fine for a first offence is $1,000 CAD. However, if your blood alcohol level was extremely high (e.g., 120 mg or 160 mg), the minimum fine increases to $1,500 or $2,000 CAD.
  • Victim Surcharge: The federal government automatically adds a 30% victim surcharge to your fine.
  • Insurance Increases: If convicted, your regular auto insurance provider will drop you. You must seek “facility insurance” (high-risk coverage), which can cost between $8,000 and $12,000 CAD annually for up to three years.
  • Lawyer Fees: Retaining a private law firm to fight the charges in Newmarket generally costs between $5,000 and $15,000 CAD.
Number of OffencesMandatory CustodyFederal Driving Prohibition
First OffenceNone (Fines Only)Minimum 1 Year
Second OffenceMinimum 30 Days JailMinimum 2 Years
Third OffenceMinimum 120 Days JailMinimum 3 Years (MTO lifetime ban)

How Long Does the Process Take?

An impaired driving case generally takes anywhere from 6 to 18 months to reach a final trial date in Newmarket. ⌛ If you are convicted, the driving prohibition begins immediately upon sentencing. For a first-time offender, the prohibition is exactly one year.

However, Ontario allows eligible first-time offenders to participate in the Ignition Interlock program (Stream A). If you plead guilty early, you might be allowed to install a breathalyzer in your car and resume driving after just 3 to 6 months of absolute prohibition, drastically shortening your time without a vehicle.

Frequently Asked Questions (FAQ)

Can a judge ignore the mandatory minimum sentence?

No. Under the Criminal Code of Canada, a judge has no legal authority to sentence you below the mandatory minimums if you are found guilty of impaired driving. Only the Crown attorney can withdraw or reduce the actual charge.

What is the penalty for refusing the breathalyzer?

Refusing to provide a breath sample is a distinct criminal offence. The mandatory minimum penalty for a first-time refusal is a $2,000 CAD fine and a 1-year driving prohibition-which is double the financial penalty of blowing over the legal limit.

Will I definitely go to jail for a first offence?

Generally, no. A standard first-time impaired driving conviction does not require mandatory jail time; it involves fines and a driving ban. However, if your impaired driving caused a severe accident resulting in bodily harm or death, jail time is highly likely.

Do I get a criminal record if convicted?

Yes. Impaired driving is an indictable or summary conviction offence under the Criminal Code. A conviction results in a permanent criminal record, which can prevent you from crossing the U.S. border and limit your employment prospects.
