The accused was charged with operating a motor vehicle while impaired by a drug (marijuana) on June 25, 2014, in Ottawa.
The Crown proved beyond a reasonable doubt that the accused's ability to operate a motor vehicle was impaired by marijuana.
The evidence included observations of marijuana smoke emanating from the vehicle, the accused's admission to smoking, and performance on drug influence evaluation tests administered approximately one to one and a half hours after the stop.
The court found that divided attention tests, particularly the modified Romberg balance test, heel-to-toe walk, and one-leg stand test, demonstrated significant impairment of the accused's ability to perform tasks requiring divided attention, which is essential to safe driving.
The accused was convicted on both the impaired driving charge and the marijuana possession charge.
