Real Scenarios
1
Breathalyzer & Blood Alcohol Evidence
Breathalyzer results are often the key evidence in impaired driving cases. Challenging the reliability of the instrument, the procedures followed, or the statutory presumptions requires strong case law.
Prompt:
“Can breathalyzer results be challenged if the officer did not follow proper procedures?”
Casey returns cases where courts excluded or questioned breathalyzer evidence due to procedural errors, instrument malfunction, or failure to comply with statutory requirements — showing lawyers which arguments have worked.
2
Roadside Screening & Approved Instruments
The initial roadside demand and the subsequent approved instrument test each have their own legal requirements. Understanding the distinction and the grounds for challenge is essential for any impaired driving defence.
Prompt:
“What are the legal requirements for a valid roadside breath demand?”
Casey surfaces decisions analyzing the reasonable suspicion standard, the officer's obligation to administer the test promptly, and cases where courts found the demand was not lawfully made.
3
Impaired Driving Sentencing & Minimums
Impaired driving convictions carry mandatory minimum fines and, for repeat offences, mandatory jail time. Sentencing ranges vary based on circumstances, and lawyers need comparable cases to make effective submissions.
Prompt:
“What is the typical sentence for a second impaired driving offence in Canada?”
Casey retrieves cases showing sentencing ranges for repeat impaired driving offenders, the factors judges considered in aggravation and mitigation, and how courts applied the mandatory minimum provisions.
4
Licence Suspension & Driving Prohibitions
Impaired driving charges trigger both criminal and administrative consequences, including immediate licence suspensions and post-conviction driving prohibitions. Understanding both streams is important for anyone facing charges.
Prompt:
“Can an administrative licence suspension be challenged separately from the criminal charge?”
Casey returns cases where courts reviewed administrative suspensions, the relationship between administrative and criminal proceedings, and the grounds on which suspensions have been overturned.
5
Refusal to Provide a Breath Sample
Refusing to provide a breath sample is a separate criminal offence that carries the same penalties as impaired driving. Accused individuals often do not realize this, and the defence options are narrow but important.
Prompt:
“What constitutes a reasonable excuse for refusing to provide a breath sample?”
Casey surfaces decisions where courts assessed reasonable excuse defences, including medical conditions, language barriers, and confusion about rights — showing the high threshold courts apply to this defence.
6
Charter Rights & Right to Counsel
Impaired driving investigations frequently raise Charter issues, particularly the right to counsel and the right against unreasonable delay. These issues can result in evidence exclusion if properly argued.
Prompt:
“Does a delay in providing access to counsel affect the admissibility of breath sample results?”
Casey returns cases where courts analyzed right to counsel violations during impaired driving investigations, the impact of delay on breath sample admissibility, and how judges applied the section 24(2) exclusion framework.
Real Scenarios
Breathalyzer results are often the key evidence in impaired driving cases. Challenging the reliability of the instrument, the procedures followed, or the statutory presumptions requires strong case law.
Prompt:
“Can breathalyzer results be challenged if the officer did not follow proper procedures?”
Casey returns cases where courts excluded or questioned breathalyzer evidence due to procedural errors, instrument malfunction, or failure to comply with statutory requirements — showing lawyers which arguments have worked.
Impaired driving is the single most common criminal offence in Canada, and the 2018 amendments to the Criminal Code gave police new powers to demand breath samples without reasonable suspicion at roadside stops.
