The panel offers a practical, candid look at how experts influence the outcome of trials, emphasizing that expert testimony can determine whether a case succeeds or fails. Judges and experienced litigators share insight on selecting, retaining, and instructing experts, meeting the requirements of R. v. Mohan and White Burgess Langille Inman, and complying with Rule 53.03 of the Ontario Rules of Civil Procedure.
The conversation addresses the realities of expert bias, financial arrangements, the use of participant versus litigation experts, and the expanding role of technology and AI in expert analysis. The speakers discuss admissibility challenges, late reports, multiple signatories, the problem of “hired guns,” and how courts are applying stricter gatekeeping standards to ensure independence and necessity.
Through case examples and audience polls, the session highlights how to manage expert costs, test reliability through cross-examination, and maintain ethical boundaries when assisting in report preparation. The discussion closes with best practices for budgeting, using visual aids effectively, and presenting persuasive, compliant expert evidence that withstands judicial scrutiny
