The accused was charged with operating a motor vehicle with a blood alcohol concentration exceeding 80 milligrams per 100 millilitres of blood and having care or control of a motor vehicle on December 31, 2013.
The vehicle had mounted a snowbank after the accused swerved to avoid a collision.
When police arrived, the accused was found in the driver's seat with keys in the ignition.
The court examined whether the accused had care or control of the vehicle despite it being immobilized on the snowbank, and whether the breath samples were taken as soon as practicable as required by law.
The court found the accused guilty on both counts.
