Noushin Mazooryi DUI

DUI & Impaired Driving Defence Lawyer

A DUI charge in Ontario can carry consequences that extend far beyond a courtroom — an immediate roadside licence suspension, vehicle impoundment, and, if convicted, a criminal record, a lengthy licence suspension, and mandatory ignition interlock. Mazrooyi Law Professional Corporation provides strategic, detail-driven defence for individuals charged with impaired driving throughout Markham, Richmond Hill, Vaughan, and York Region.

Impaired driving cases often turn on technical and procedural details — how a breath sample was obtained, whether your Charter rights were respected, and whether police followed proper investigative steps. A careful, thorough review of these details is often where the strongest defences are found.

Types of Impaired Driving Charges We Defend

  • Impaired operation — operating a motor vehicle while your ability is impaired by alcohol or drugs
  • Over 80 — operating a motor vehicle with a blood alcohol concentration at or above the legal limit
  • Refusal charges — failing or refusing to provide a breath, blood, or physical sobriety sample when lawfully demanded
  • Drug-impaired driving — charges arising from a Drug Recognition Expert (DRE) evaluation or drug screening
  • Impaired driving causing bodily harm or death — the most serious category of impaired driving offence, carrying significantly increased penalties

Penalties You May Be Facing

Ontario’s impaired driving penalties apply at both the administrative (roadside) and criminal levels, and have become significantly stricter in recent years:

  • Immediate roadside licence suspension — a 90-day Administrative Driver’s Licence Suspension (ADLS) typically applies where a driver registers a blood alcohol concentration at or above the criminal threshold, or fails standardized field sobriety testing
  • Vehicle impoundment — commonly 7 days at the roadside stage
  • Mandatory ignition interlock — required on conviction, and often for repeat or high-BAC occurrences even before conviction
  • Criminal fines and imprisonment — a first conviction carries a mandatory minimum fine, with escalating and potentially custodial penalties for repeat offences
  • Extended licence suspension — on conviction, suspensions typically run at least one year and increase substantially for repeat offences
  • A criminal record — with lasting consequences for employment, travel, and insurance rates


Ontario has also extended the “look-back period” used to determine whether an offence counts as a first, second, or subsequent occurrence, meaning a past incident can affect your case for longer than it once did. We review the specifics of your record and charge to give you a clear, accurate picture of what you’re facing.

How We Approach Your DUI Defence

  • Reviewing the traffic stop — did police have proper grounds to stop and detain you?
  • Scrutinizing breath and testing procedures — was the approved instrument used and calibrated correctly, and were proper timelines followed?
  • Assessing Charter compliance — including your right to counsel and protection against unreasonable search and detention
  • Full disclosure review — examining officer notes, video, and testing records for inconsistencies
  • Negotiating with the Crown — pursuing reduced charges or alternative resolutions where appropriate

Frequently Asked Questions

An immediate roadside suspension typically applies as soon as you’re charged, separate from any criminal conviction. If convicted, an additional and longer licence suspension applies as part of the criminal penalty. We can advise on options that may apply during this period.

It depends on the facts of your case. Outcomes can range from a full withdrawal of charges to a reduced charge or an acquittal after trial, depending on issues with the evidence, testing procedures, or your Charter rights. A detailed review of your specific case is the only way to assess your options.

Yes. Even a first offence carries a mandatory minimum fine, a criminal record, and a lengthy licence suspension. Given the technical nature of impaired driving law and the severity of the consequences, experienced legal representation is strongly recommended.

As soon as possible. Early involvement allows us to advise you on what to say (and not say), begin reviewing disclosure, and identify time-sensitive issues — such as licence suspension appeals — before deadlines pass.
