The accused was charged with impaired operation of a motor vehicle and operation with a blood alcohol level over 80 mg/100 mL following a motor vehicle collision on June 23, 2011.
The Crown relied on breath samples showing readings of 170 and 160 mg/100 mL, officer observations of impairment, and expert toxicology evidence.
The defence challenged the timing of the accident and the reliability of impairment indicators.
The court found reasonable doubt regarding the exact time of the accident, preventing reliance on the statutory presumption.
The court also found conflicting evidence regarding impairment, with some officers and the victim not observing signs of impairment despite high blood alcohol readings.
The court rejected a purely scientific definition of impairment in favour of traditional legal indicators.
The accused was acquitted on both charges.
