A single traffic stop can change your life. One moment you are driving home, the next you are being asked to blow into a roadside screening device and handed paperwork suspending your licence. Impaired driving charges are among the most common criminal charges in Ontario, and they carry consequences that go far beyond a fine. If you have been charged with DUI in Mississauga, here is what you need to know and why speaking with an experienced criminal lawyer in Mississauga early can protect your future.
What Counts as Impaired Driving in Canada?
Impaired driving offences are found in the Criminal Code. The most common charges include:
- Impaired operation: driving while your ability is impaired to any degree by alcohol, drugs or both
- Over 80: having a blood alcohol concentration of 80 milligrams or more of alcohol in 100 millilitres of blood within two hours of driving
- Refusal: failing or refusing to comply with a lawful demand for a breath, blood or drug sample
- Drug-impaired driving: driving with prohibited levels of THC or other drugs in your blood
Since 2018, police can demand a roadside breath sample from any lawfully stopped driver, even without suspecting alcohol use. This is called mandatory alcohol screening.

Immediate Consequences in Ontario
Even before you go to court, Ontario imposes serious administrative penalties if you register a fail or are charged:
- A 90-day Administrative Driver’s Licence Suspension
- A 7-day vehicle impoundment
- Administrative monetary penalties and reinstatement fees
These penalties apply regardless of whether you are later found guilty, which is why many people are shocked by how quickly they lose their ability to drive.
Penalties if Convicted
For a first offence, a conviction typically results in a mandatory minimum fine of $1,000, which increases for higher blood alcohol readings, and a one-year driving prohibition. Refusal carries a higher minimum fine. Repeat offences can lead to mandatory jail sentences and much longer driving prohibitions. A conviction also means a permanent criminal record, higher insurance premiums for years and possible problems with employment, travel to the United States and immigration status.
Some first-time offenders may qualify for Ontario’s reduced suspension program with an ignition interlock device, which can shorten the time off the road. A lawyer can explain whether this is an option for you.
Common Defences in DUI Cases
Every impaired driving case is different, but experienced defence lawyers look closely at issues such as:
- Whether the police had lawful grounds to stop the vehicle
- Whether breath samples were taken properly and within the legal time limits
- Whether the breathalyzer was properly maintained and operated by a qualified technician
- Whether you were promptly informed of your right to counsel and given a real chance to speak with a lawyer
- Whether the officer’s observations of impairment are supported by video and other evidence
- Whether there are disclosure problems or unreasonable delays
Charter violations can lead to evidence being excluded, which can result in charges being withdrawn or an acquittal.
Where Will Your Case Be Heard?
Criminal charges laid in Mississauga by Peel Regional Police are generally heard at the Ontario Court of Justice in Brampton. Understanding how Peel Crown prosecutors approach impaired driving files helps a defence lawyer assess whether a trial or a negotiated resolution makes the most sense.
Mistakes to Avoid After a DUI Charge
- Driving while your licence is suspended, which creates a new and serious charge
- Discussing the night with friends online or by text
- Assuming the breath reading means the case cannot be defended
- Pleading guilty at your first appearance without legal advice
