The plaintiff brought a motion under Rule 30.10 of the Rules of Civil Procedure seeking production of the full Special Investigations Unit (SIU) investigative file in a civil action alleging negligence, assault, and Charter breaches arising from a police use-of-force incident.
The SIU, a non‑party, resisted production of certain civilian and police witness statements that had been obtained under assurances of confidentiality.
The court applied the factors from Ontario (Attorney General) v. Stavro and emphasized that a moving party must demonstrate both relevance and that proceeding to trial without the documents would be unfair.
The court found the plaintiff had not made reasonable efforts to obtain evidence from available witnesses and could not rely on the SIU investigation as a substitute for civil discovery.
Production of the remaining witness statements was therefore refused.
