The respondent, owner of lands east of Lake Superior Provincial Park, sought to use a road within the Park to access its lands for timber harvesting.
The Acting Park Superintendent denied the request based on the 1995 Lake Superior Provincial Park Management Plan.
The application judge granted judicial review, finding the Superintendent's interpretation incorrect and procedurally unfair.
The Court of Appeal allowed the Minister's appeal, holding that the application judge erred by applying a correctness standard.
Applying a pragmatic and functional approach, the Court determined the standard of review was reasonableness or patent unreasonableness, and found the Superintendent's interpretation of the policy document was not unreasonable.
