Over his career, Mr. McKinnon has tried thousands of cases, and as a judge regularly sat on the Divisional Court of Appeal, hearing civil and administrative law appeals. He was also invited to sit on the Court of Appeal as an ‘ad hoc’ judge. Mr. McKinnon is renowned for his ability to grasp issues quickly, listen politely, treat counsel and witnesses with respect, focus on the big picture and render judgments in a timely manner. He is regarded as an expert in the law of evidence. Mr. McKinnon has presided over many high-profile criminal cases, including charges of homicide, terrorism and commercial fraud.
