During a jury trial for importing cocaine, the Crown sought to admit opinion evidence from a police officer regarding the pricing and value of cocaine imported through Pearson Airport.
The defence challenged the admissibility of the proposed expert evidence, arguing the witness lacked proper qualifications and that the evidence could improperly influence the jury.
Applying the criteria for expert evidence from R. v. Mohan and the Supreme Court’s guidance in R. v. Sekhon, the court assessed relevance, necessity, absence of exclusionary rules, and proper qualification.
The court found that the evidence was relevant to the issue of the accused’s knowledge and that the jury would not otherwise understand the value of the quantity of cocaine involved.
Based on the officer’s extensive investigative experience and exposure to pricing information through investigations and intelligence sources, the court concluded he possessed the requisite specialized knowledge and permitted the opinion evidence.
