The defendant was charged with driving with a blood alcohol concentration exceeding 80 milligrams per 100 millilitres of blood.
The Crown relied on Intoxilyzer tests taken more than two hours after the defendant was stopped, requiring expert toxicology evidence to establish the defendant's blood alcohol level at the time of driving.
The Crown's expert opined the defendant's BAC was 95 to 140 mg/100ml at the time of driving, based on an assumption of no "bolus drinking." The defendant challenged the admissibility of his weight statement on Charter grounds and argued the Crown failed to prove the absence of bolus drinking.
The court rejected the Charter challenges, admitted the defendant's weight statement, and found the Crown proved beyond a reasonable doubt that the defendant did not consume two standard drinks within 20 minutes before driving.
The defendant was convicted.
