Charged with Impaired Driving or DUI in Sarnia?

The lawyer you choose matters more than most people realize. David Doney has been defending impaired driving and DUI cases in Ontario since 1976. That is nearly five decades of courtrooms, thousands of cases, and a depth of experience very few lawyers in this province can match.

David knows both sides of the courtroom. As a former drug prosecutor, he knows exactly how the Crown builds an impaired driving case and where it can be taken apart.


A Charge Is Not a Conviction

Being charged with impaired driving or DUI is serious. But it is not the end of the road. The Crown must prove its case beyond a reasonable doubt. Police mistakes, gaps in evidence, and rights violations are real. In the hands of an experienced lawyer, they matter.

David has spent nearly five decades finding those gaps. He stays current on impaired driving legislation and roadside testing technology. He trains regularly in DUI defence. And he is a member of the Criminal Lawyers' Association, sitting on multiple legal committees. His clients benefit from that knowledge every time he walks into a courtroom.


What a DUI Conviction Can Cost You

A conviction for impaired driving in Ontario is not just a fine. It can mean a lifelong criminal record, a licence suspension, jail time, skyrocketing insurance premiums, and restrictions on employment and travel. These consequences follow you. They affect your family. They are worth fighting.

David does not steer clients toward guilty pleas because it is faster or easier. Every client deserves a full and honest assessment of their options before any decision is made. A rushed guilty plea is not a defence.

Common Questions About Impaired Driving and DUI Charges in Sarnia

What is the difference between impaired driving and DUI in Ontario?

In Ontario, impaired driving and DUI refer to the same category of offence under the Criminal Code of Canada. A person can be charged based on observed impairment, a blood alcohol concentration over the legal limit, or impairment by drugs. The specific charge depends on the circumstances of the stop and the evidence collected.

Can an impaired driving charge be beaten?

Yes. Many impaired driving charges are successfully defended. Police are required to follow strict procedures during a traffic stop and breath testing. If those procedures were not followed, if your rights were violated, or if there are gaps in the evidence, a skilled defence lawyer can challenge the charge. David has been doing exactly that since 1976.

What happens if I am convicted of impaired driving in Ontario?

A first conviction carries a mandatory minimum fine, a licence suspension, and a criminal record. Subsequent convictions carry harsher penalties including jail time. A criminal record for impaired driving can affect your employment, your insurance rates, and your ability to travel outside Canada. These are serious consequences worth fighting.

Should I just plead guilty to an impaired driving charge?

Not before speaking to a lawyer. Many people assume the evidence against them is stronger than it is. An experienced DUI lawyer will examine the full picture before any decision is made. David does not push clients toward guilty pleas. He gives every client an honest assessment of their options first.

How long has David Doney been defending impaired driving cases?

David has been defending impaired driving and DUI cases in Ontario since 1976. Nearly five decades. Thousands of cases. He is a member of the Criminal Lawyers' Association, sits on multiple legal committees, and trains regularly in DUI defence to stay current with changes in the law and testing technology.

Does David Doney only practise in Sarnia?

David's office is in Guelph, but he serves clients across southwestern Ontario. If you are facing an impaired driving charge in the region, call to discuss your situation.

What does a free consultation actually mean?

It means you call, you explain your situation, and David gives you an honest assessment. No charge, no obligation, no pressure. You will leave the call knowing where you stand and what your options are. That is it.
