R v. MacSween

R v. MacSween

Officers had objectively reasonable grounds to arrest for drug-impaired driving based on credible eyewitness accounts and police observations; the warrantless search and urine testing did not breach s.8; the delay awaiting an accredited evaluating officer and conducting the evaluation did not amount to arbitrary detention under s.9 because the demand was made and executed as soon as practicable; pre-arrest statements were not admitted for trial; on the admissible evidence the accused was proven guilty of driving while impaired by drugs under s.320.14 and not guilty of public mischief under s.140.
