Canadian Criminal Case Law Summary
Driver’s Seat Presumption – Impaired Driving
In impaired driving law, the driver’s seat presumption means, that a person found behind the wheel of a motor vehicle is presumed to have the care or control of the vehicle. If their ability to drive was impaired, they can face an impaired driving charge even if the vehicle never moved.
In R. v. Whyte, police found Mr. Whyte slumped over the steering wheel of a parked car. His ability to operate the car was impaired by alcohol. The Crown Attorney raised the presumption that Whyte was guilty of having care and control of a motor vehicle while impaired.

What Is a Presumption in Criminal Law?
A presumption is a rule that tells a court to treat something as fact once another fact has been proven. Some presumptions can be challenged, but the law sets out what the accused must show.
In R. v. Whyte, the rule worked this way:
- The Crown proved that Mr. Whyte occupied the driver’s seat.
- The court presumed that he had care or control of the vehicle. The Crown did not have to prove that the car moved.
- Mr. Whyte could challenge the presumption by proving that he did not enter the car to set it in motion.
This placed a reverse onus on Mr. Whyte. He had to prove his reason for entering the car on a balance of probabilities. In plain language, the court had to find his explanation more likely than not. Simply raising a reasonable doubt was not enough.
What Happened in R. v. Whyte?
Mr. Whyte was charged with care and control of a motor vehicle while impaired. Police found him sitting in the driver’s seat of his car with his body slumped over the steering wheel.
The vehicle was parked along the roadside. The engine was not running, but the key was in the ignition and the dashboard ignition light was on. The defence accepted that Mr. Whyte’s ability to operate a motor vehicle was impaired by alcohol.
The important issue was whether the driver’s-seat presumption could be used to establish that Mr. Whyte had care or control of the vehicle.
The Criminal Code of Canada section 320.35 states:
“If it is proved that the accused occupied the seat or position ordinarily occupied by a person who operates a conveyance, the accused is presumed to have been operating the conveyance unless they establish that they did not occupy that seat or position for the purpose of setting the conveyance in motion.“
Mr. Whyte challenged this presumption under s. 11(d) of the Canadian Charter of Rights and Freedoms, which guarantees the right to be presumed innocent.
What Happened at Trial
The trial judge rejected his argument and convicted him. Significantly, the judge later stated that without the driver’s-seat presumption, he would have acquitted Mr. Whyte. His conviction was upheld on appeal, and the case eventually reached the Supreme Court of Canada.
The Supreme Court concluded that the presumption infringed the Charter’s presumption of innocence because simply being in the driver’s seat did not necessarily prove care or control. There could be other reasonable explanations for why someone was sitting there.

The Legal Issue Before the Court
Police found Mr. Whyte in the driver’s seat of a parked car. The law presumed he had care or control of the car unless he proved that he did not get in to drive it.
The Supreme Court had to answer two questions:
- Did the rule violate the right to be presumed innocent? It could require a guilty verdict even if the judge had doubts about whether Mr. Whyte had care or control.
- If it did, could the rule still be justified? The Court had to decide whether public safety justified this limit on his Charter right.
The Court’s answers would decide whether the driver’s seat presumption could be used in Mr. Whyte’s impaired driving case.
What the Court Confirmed
The Supreme Court confirmed that the presumption of innocence is a core principle of Canadian criminal law.
The Supreme Court said the driver’s seat rule went against the right to be presumed innocent. A person could sit behind the wheel without planning to drive. But the rule put the burden on that person to prove it.
The Court still allowed the rule because it was meant to reduce the danger of impaired driving. Mr. Whyte could not overcome the presumption, so his impaired driving conviction stood.
For someone facing a DUI charge today, the reason they sat in the driver’s seat is an important part of the evidence. A DUI lawyer will review what the police saw, why the person entered the vehicle, and whether the driver’s seat presumption can be challenged.
Challenging the Care & Control Presumption?
If the Crown proves you occupied the driver’s seat, the Criminal Code presumes you operated the vehicle. You can challenge that presumption by establishing that you did not sit there to set it in motion. What you planned to do, and what evidence supports your account, matters. laws-lois.justice.gc.ca
Our defence lawyers at Charitsis Law review the full sequence of events. Useful evidence can include:
- Plans for another ride: Did you call a taxi or ask someone to pick you up?
- Messages and call records: Do they show when you made that plan?
- The vehicle’s condition: Where were the keys? Was the engine running?
- Witnesses and police video: Do they support your account of what happened?
In a care and control case we fought, our client was impaired and sitting in the driver’s seat. Nicholas Charitsis presented a text the client had sent asking his girlfriend to pick him up. The client also testified about his plan. The judge accepted the evidence and found him not guilty. It shows why a DUI lawyer should look for proof of an alternate plan to get home.

FAQs About Presumptions & Drinking and Driving
Q. What is a presumption in an impaired driving case?
A. A presumption is a legal rule that tells the court to treat something as true once another fact has been proven. It does not mean the Crown Attorney has proved every part of an impaired driving charge.
For example, if the Crown proves you were sitting in the driver’s seat, the Criminal Code presumes you operated the vehicle. This matters even if the car was parked and police never saw you drive. A DUI lawyer can review the evidence and challenge the presumption.
Q. Does sitting in the driver’s seat mean I had care and control?
A. Sitting in the driver’s seat triggers a legal presumption of operation. Under Canadian impaired driving law, operating a motor vehicle includes driving it or having care or control of it. That is why police can lay a drinking and driving charge when they find someone impaired in a parked car.
You can challenge the presumption by establishing that you did not occupy the seat to set the vehicle in motion. Our defence lawyers examine why you entered the car, what you planned to do, and whether the evidence supports your explanation.
Q. What does “reverse onus” mean in a care and control charge?
A. The Crown normally has to prove a criminal charge beyond a reasonable doubt. The driver’s seat presumption creates a specific exception. Once the Crown proves you occupied that seat, you must establish that you were not there for the purpose of setting the vehicle in motion. Simply raising a reasonable doubt about your purpose does not rebut this presumption.
That does not relieve the Crown of proving the other elements of the impaired driving offence. Your defence lawyer can examine the evidence of impairment, the timing of events, and what police actually observed, as well as the reason you were in the vehicle.
Q. Can I fight a care and control charge if I was waiting for a ride?
A. Yes. Arranging another way home can help show that you had decided not to drive. A text asking someone to pick you up, a taxi booking, call records, or a witness who knew your plan can all be useful evidence. The court will consider those details alongside your actions at the vehicle.
In one case fought by Charitsis Law, police found our client impaired in the driver’s seat. Nicholas Charitsis presented a text showing that the client had asked his girlfriend to pick him up. The client testified about his plan, and the judge found him not guilty. Every case turns on its own evidence, but an alternate plan to get home can be important.
Q. Is saying “I did not intend to drive” enough to fight a DUI charge?
A. Your explanation is a starting point. A court will also consider what you did and whether other evidence supports your account. For example, a DUI lawyer can review where the keys were, whether the engine was running, how long you had been in the car, and whether you contacted someone for a ride.
Our defence lawyers also assess whether your actions created a realistic risk that the vehicle could be set in motion. Reviewing the police notes, video, messages, and witness accounts helps us identify the strongest defence strategy for a care and control charge in Ontario.
