The accused was charged with impaired driving and driving with excess blood alcohol (over 80 mg/100 ml) following a traffic stop on Highway 401.
The Crown relied on Intoxilyzer breath test results showing readings of 104 and 99 mg/100 ml.
The accused challenged the admissibility of the breath test results on Charter grounds, alleging violations of sections 7, 8, 10(a), and 10(b).
The court found that while the accused's right to silence under section 7 was breached when the breath technician misinformed him about the scope of that right, the breach did not warrant exclusion of the evidence under section 24(2).
The court found the officer had reasonable grounds to make the breath demand based on the accused's erratic driving and physical signs of impairment.
The court rejected arguments regarding the reliability of the Intoxilyzer machine and the alcohol standard solution used for calibration.
The accused was convicted on both counts.
