How to dispute an immediate 90-day ADLS license suspension in Ottawa

To dispute an immediate 90-day Administrative Driver’s Licence Suspension (ADLS) in Ontario, you must file a formal appeal with the Licence Appeal Tribunal (LAT). You can only win if you prove mistaken identity or a specific medical emergency, and the filing fee is $106 CAD.

Losing your ability to drive overnight is a devastating blow to your daily life. In Ontario, failing a breath test or refusing to provide a sample triggers an immediate 90-day Administrative Driver’s Licence Suspension (ADLS). This provincial penalty happens before you ever step foot inside a criminal courtroom, leaving many drivers feeling like they are being punished before they are proven guilty.

While it feels unfair, knowing how to dispute an immediate 90-day ADLS license suspension in Ottawa is possible. 📋 However, the rules set by the Ministry of Transportation (MTO) are incredibly strict. You cannot appeal simply because you need your vehicle to travel to work. It is highly recommended to consult a local criminal defence law firm to evaluate whether an appeal is actually worth your time and money.

Step-by-Step Process in Ottawa

Whether you were arrested in suburban Kanata or the downtown ByWard Market, all ADLS appeals in Ontario are handled remotely by the Licence Appeal Tribunal (LAT). You will not go to the Elgin Street Courthouse for this administrative process.

Step 1: Determine Your Grounds for Appeal

The LAT will only cancel your suspension under very narrow circumstances. 🔍 You must prove one of two things: either the police suspended the wrong person’s licence (mistaken identity), or you failed/refused the breath test due to a sudden, documented medical emergency (such as an asthma attack that prevented you from providing a sufficient breath sample).

Step 2: File the Appeal with the LAT

If you meet the criteria, your lawyer will help you submit an “Appeal of an Administrative Driver’s Licence Suspension” form. This application must be filed electronically with the Licence Appeal Tribunal, along with all supporting evidence, such as medical records from an Ottawa hospital or doctor.

Step 3: Attend the Case Conference

Once the LAT processes your application, they will schedule a virtual or telephone hearing. 💻 A representative from the Ministry of Transportation will attend to defend the suspension. Your lawyer will present your medical evidence or proof of mistaken identity to the tribunal adjudicator.

Step 4: Await the Adjudicator’s Decision

After hearing both sides, the adjudicator will issue a written decision. If you win, the MTO will be ordered to reinstate your driver’s licence immediately, though you will still need to visit ServiceOntario. If you lose, the 90-day suspension remains in full effect.

How Much Does it Cost in Ottawa?

Appealing an ADLS is a completely separate financial process from fighting your criminal charges. You should carefully weigh these costs against the likelihood of actually winning your appeal at the LAT.

  • LAT Filing Fee: The provincial government charges a non-refundable $106 CAD fee to file your appeal application.
  • Medical Documentation: Obtaining specialized medical reports from a doctor to prove your inability to blow into a breathalyzer can cost between $150 and $500 CAD.
  • Lawyer Fees: Having a professional law firm prepare and argue your LAT appeal typically costs an additional $1,500 to $3,500 CAD.
  • ServiceOntario Reinstatement: Even if you win the appeal, you may still be required to pay the standard $281 CAD reinstatement fee to get your physical card back.

How Long Does the Process Take?

Because the suspension is only 90 days long, the LAT is legally required to fast-track these specific hearings. 🕑 However, administrative delays can still eat into your suspension time.

Phase of the AppealEstimated Timeline
Filing the LAT ApplicationUsually done within 3 to 7 days of arrest
Scheduling the HearingLAT must hold the hearing within 30 days
Receiving the DecisionUsually 1 to 2 weeks after the hearing
Total Appeal DurationTypically takes 4 to 6 weeks start to finish

Frequently Asked Questions (FAQ)

Can I get a temporary licence to drive to work?

No. Ontario does not issue “hardship” or restricted licences for work purposes. If your licence is suspended under the ADLS program, you absolutely cannot drive for any reason until it is officially reinstated.

Does appealing the suspension pause the 90 days?

No. Filing an appeal with the Licence Appeal Tribunal does not pause or stay the suspension. You remain prohibited from driving while you wait for your hearing date and the adjudicator’s final decision.

What happens to my criminal case if I win the LAT appeal?

Winning at the LAT only lifts the administrative provincial suspension. The criminal charges for impaired driving or “Over 80” are completely separate and will still proceed at the Ottawa Courthouse.

Can the Crown Attorney lift my 90-day suspension?

No. The Crown Attorney handles the criminal prosecution under the Criminal Code of Canada. They have no jurisdiction over the Ministry of Transportation’s provincial licensing suspensions.

Is it worth appealing if I don’t have a medical excuse?

Generally, no. If you cannot prove mistaken identity or a valid medical reason for failing/refusing the breathalyzer, the LAT will almost certainly dismiss your appeal, and you will lose your filing fees.
