The Short Answer

Do I need an impaired driving lawyer in Toronto for a first DUI?

Yes — a first DUI in Toronto is a Criminal Code charge, and an impaired driving lawyer in Toronto can test the stop, the breath demand and the instrument evidence before you decide anything. Aaron M. Spektor, called to the Ontario Bar in 1997, reviews the full disclosure for Charter breaches and technical defects. Because a DUI conviction cannot end in a discharge, the defence work matters from day one. Consultations are free and confidential.

Overview

What this practice is, and is not.

Impaired driving is the most heavily charged criminal offence in Canada, and the most heavily litigated. In Ontario, a charge triggers an immediate 90-day Administrative Driver's Licence Suspension and a 7-day vehicle impoundment at the roadside — before any court date. A first conviction carries a minimum $1,000 fine (more at higher breath readings), a one-year Canada-wide driving prohibition, an automatic criminal record, and serious immigration and insurance consequences, often for an otherwise law-abiding driver.

Aaron M. Spektor approaches every file methodically and with focus: review complete disclosure of the evidence, vet the breath technician's qualifications and the instrument's calibration, scrutinize the roadside detention, and scrutinize every possible Charter issue available. Because these are the most Charter-litigated cases in Canada, that review frequently reveals a defence that is not obvious on the night of the arrest.

Aaron defends impaired driving charges across the Greater Toronto Area. For location-specific guidance, see our focused pages for an impaired driving lawyer in Toronto or a DUI lawyer in Mississauga. New to the process? Read First DUI in Ontario: penalties, licence suspension and defence options.

Some impaired charges resolve without a trial — withdrawn, reduced to careless driving, or stayed. Aaron's approach helps to increase the chances to resolve impaired charges without trial. The cases that do proceed to trial are defended with the same preparation. To discuss your matter, call (416) 599-1900 or request a consultation.

Our Approach

How we work this practice.

  1. 1

    Receive and review the disclosure.

    Police notes, breath-room video, technician certificates, maintenance records, dispatch logs — everything the Crown intends to rely on.

  2. 2

    Map the Charter issues.

    Detention onset, right to counsel implementation, breath-demand timing, instrument-related disclosure under R. v. Stinchcombe.

  3. 3

    Negotiate from a litigation-ready posture.

    Crown counsel takes positions differently when defence has filed Charter notices and is prepared to litigate them.

  4. 4

    Try the case when trial is the right answer.

    Where the Crown will not move and the defence is strong, we set the matter down for trial and prepare to win it.

Beyond the breath test

DUI Lawyer Toronto: What the Crown Must Prove and What’s at Stake

What the Crown must prove under section 320.14

Section 320.14 of the Criminal Code creates several distinct offences, and each has its own elements. For impaired operation, the Crown must prove you were operating — or in care or control of — a conveyance while your ability was impaired to any degree by alcohol, a drug, or both. For Over 80, it must prove a blood-alcohol concentration of 80 mg or more in 100 mL of blood within two hours of ceasing to operate. Drug-impaired cases run on a separate track, built on Drug Recognition Evaluator evidence and blood-drug concentration limits.

How Toronto police build an impaired file — and where it breaks

Since December 2018, officers can demand a roadside breath sample from any lawfully stopped driver under mandatory alcohol screening, without suspecting alcohol. A fail on the approved screening device usually supplies the grounds for arrest and a demand for two samples into an approved instrument at the station, with the lower reading used. Each step generates records: the officer’s notes, in-car and booking video, the instrument’s test record and the technician’s certificate. Gaps between the stop, the demand, the right-to-counsel call and the first test are where defences are usually found. If you declined to blow, read refusing a breathalyzer in Ontario.

Sentencing: why a discharge is off the table

Impaired offences carry mandatory minimum penalties — a fine on a first conviction, then 30 days’ jail for a second and 120 days for each later offence. Because a minimum is prescribed, a judge cannot grant an absolute or conditional discharge, so a finding of guilt means a criminal record. That is why the realistic goals are an acquittal, a withdrawal or a negotiated plea to a non-criminal Highway Traffic Act offence, not simply a lenient sentence.

Consequences beyond the courtroom

Parliament raised the maximum for impaired driving to ten years in 2018, which made it “serious criminality” under immigration law: a permanent resident can become inadmissible even without jail, and a foreign worker or student faces the same risk. Insurers treat a conviction as high-risk for years, and commercial and rideshare drivers can lose their work. A record can also complicate crossing the US border. Our impaired driving lawyer in Toronto page explains how these files move through the Toronto Courthouse at 10 Armoury Street.

Common Questions

Things clients ask before retaining us.

If yours is not on this list, please ask. We answer every intake inquiry personally.

Will I lose my licence immediately?

An administrative driver's licence suspension is automatic and immediate in Ontario when an officer forms reasonable grounds. That suspension is separate from the criminal proceeding. We can advise on appeals and on minimizing collateral driving consequences while the criminal case proceeds.

Can the breath reading be challenged?

Yes. Breath instruments must be operated by a qualified technician within a specific time window, with proper calibration and proper sequencing. Defects in any of these can lead to the reading being excluded or its presumptions being defeated. Disclosure review is critical.

What if it's my first offence and I just want it over with?

A first-offence impaired conviction is still a criminal record. Before any guilty plea, we assess whether the Crown's case has weaknesses that allow a withdrawal, a reduction to careless driving, or a stay. The right answer is rarely the fastest one.

Do I need to attend court myself?

For most appearances in straightforward matters, your lawyer can attend without you. For trial and certain sentencing hearings, attendance is required. We discuss this at the outset so you know what to expect.

How much does a DUI lawyer cost in Toronto?

Fees depend on whether the matter resolves at an early stage or proceeds to a contested Charter trial. After reviewing the charge, Aaron provides a clear, flat-fee quote so there are no surprises — and the initial consultation is free. Call (416) 599-1900.

What are the penalties for a first-offence DUI in Ontario (2026)?

A first conviction carries a minimum $1,000 fine (rising to $1,500 and $2,000 at higher breath readings, and $2,000 for a refusal), a one-year federal driving prohibition, and a permanent criminal record — plus a 90-day licence suspension and 7-day impoundment that apply immediately at the roadside. Mandatory remedial programming and ignition interlock follow. Because so much can be challenged, a first offence should never be conceded before the disclosure is reviewed.

Is a DUI a criminal offence in Canada?

Yes. Impaired driving, driving with a blood-alcohol concentration over 80, and refusing a breath sample are all Criminal Code offences. A conviction is a criminal record — not a traffic ticket — which is why it should be defended, not simply paid.

Can a DUI be reduced to careless driving?

Sometimes. Where the Crown's case has weaknesses — a flawed breath test, a Charter breach, or a problematic roadside stop — a reduction to careless driving under the Highway Traffic Act (a non-criminal offence) may be negotiable, avoiding a criminal record. Every file is assessed on its disclosure.

What happens if I refuse a breathalyzer in Ontario?

Refusing a breath demand is a separate criminal offence under section 320.15 of the Criminal Code, and it is punished at least as harshly as a failed test. A first-offence conviction carries a minimum $2,000 fine — double the $1,000 minimum for most over-80 cases — plus a driving prohibition of one to three years. Ontario also imposes an immediate 90-day administrative licence suspension. A refusal can be defended where the demand was unlawful or there was a reasonable excuse.

Can police in Ontario demand a breath sample if they don’t suspect I’ve been drinking?

Yes. Since December 2018, mandatory alcohol screening under section 320.27(2) of the Criminal Code lets an officer who has an approved screening device on hand demand a roadside breath sample from any driver who has been lawfully stopped — no suspicion required. The stop itself must still be lawful, and the demand must be made properly and promptly. Problems with the stop, the device or the timing of the demand can still support a Charter challenge.

Can I drive with an ignition interlock after a DUI in Ontario?

Often, yes. Under section 320.24(10) of the Criminal Code, a first offender can join a provincial ignition interlock program without a mandatory waiting period unless the court sets one; second and subsequent offenders must wait at least three and six months respectively. Ontario also runs a reduced-suspension interlock program for eligible first offenders who resolve their case early, so the timing of any plea decision matters. Eligibility should be checked before a resolution is agreed.

How long does a DUI stay on your record in Canada?

A DUI conviction is a criminal record that stays on file until a record suspension (formerly called a pardon) is granted by the Parole Board of Canada. Under the Criminal Records Act, you can apply five years after completing your sentence — including paying the fine — for a summary conviction, or ten years for an indictable one. Your Ontario driving record is separate. Aaron M. Spektor explains how each record will be affected before you decide how to proceed.
