The defendant was charged with dangerous driving after his SUV crossed a centre median into oncoming traffic, causing a multi-vehicle collision.
The Crown argued the defendant deliberately swerved to pass a slower car or was inattentive.
The defence argued a sudden brake malfunction forced the defendant to swerve to avoid rear-ending a vehicle.
The court found the defence expert's evidence regarding a brake-fluid leak raised a reasonable doubt.
The court also held that a momentary lapse of attention or failing to safely exit the median in a split-second emergency did not constitute a marked departure from the standard of a reasonable driver.
The defendant was found not guilty.
