The defendant was charged with impaired driving after being stopped for speeding.
The Crown relied on blood alcohol test results showing readings of 96 and 95 milligrams of alcohol per 100 millilitres of blood, taken approximately three hours after the defendant was stopped.
A toxicologist provided expert evidence that the defendant's blood alcohol level at the time of driving exceeded 80 milligrams per 100 millilitres of blood.
The defendant challenged the toxicologist's assumptions regarding elimination rates, plateau periods, breath-to-blood conversion ratios, and other factors.
The court found that while the defence raised hypothetical scenarios that could theoretically affect the calculations, there was insufficient case-specific evidence to create a reasonable doubt about the Crown's case.
The defendant was found guilty.
