The accused was charged with operating a motor vehicle with more than 80 milligrams of alcohol in 100 millilitres of blood on September 15, 2013.
The Crown's case relied on breath test results showing readings of 190 mg and 200 mg at 2:34 a.m. and 2:56 a.m., and expert toxicology evidence.
The accused claimed he had consumed five beers after backing his vehicle into a ditch while waiting for assistance, arguing this post-incident consumption explained the elevated readings.
The court rejected the accused's evidence as inconsistent with his statements to police at the scene and found his explanation lacked logical sense.
The court convicted the accused, finding that even accepting the post-incident consumption evidence, the accused's blood alcohol concentration at the time of driving would have exceeded 80 mg.
