The defendant was charged with operating a motor vehicle while impaired by a drug following a stop at a RIDE check.
The Crown sought to prove impairment through evidence of the defendant's observations at the roadside, standard field sobriety tests, a drug recognition evaluation, and toxicology results from a urine sample.
The defendant challenged the lawfulness of the SFST, DRE, and urine sample demands under the Charter.
The trial judge found reasonable suspicion for the SFST demand and reasonable and probable grounds for the DRE and urine sample demands.
However, the trial judge found that the Crown had not proven beyond a reasonable doubt that the defendant's ability to operate a motor vehicle was impaired by a drug, citing concerns about the subjectivity of the DRE examination, mixed results on physical tests, normal driving observations, and the limitations of urine testing in establishing impairment at the time of driving.
