During a grievance hearing concerning allegations that workplace harassment caused the grievor's stress and anxiety, the Employer sought production of the grievor's decoded OHIP summary for a period predating the allegations.
The Union opposed the request, arguing it was premature and overly broad.
The Board granted the Employer's request, finding that the grievor's pre-existing medical condition and causation were significant issues in dispute.
The Board ordered production subject to conditions limiting access to Employer counsel and restricting its use to the defense of the grievance.
