The accused, a transport truck driver, was charged with dangerous driving causing death after his vehicle struck a line of stopped traffic on Highway 401, killing one driver.
The Crown argued the accused failed to observe warning signs and maintain a safe distance.
The defence argued the accused was temporarily blinded by the rising sun as he rounded a curve, making the accident unavoidable.
The court found the actus reus was established but concluded the Crown failed to prove the mens rea, as the blinding sun provided a reasonable alternative explanation for the accused's failure to stop.
The accused was acquitted.
