A municipality sought an order requiring demolition of a waterfront structure constructed on Lake Rosseau, asserting that the respondent had built a boathouse with living accommodations in violation of zoning and planning by-laws.
The respondent argued the structure was a water aerodrome registered with Transport Canada and therefore immune from municipal regulation under the doctrine of interjurisdictional immunity.
The court examined the chronology of events, the respondent’s intentions, and the actual use and design of the structure.
It concluded the aerodrome registration was an attempt to circumvent municipal zoning restrictions and that the structure functioned as a boathouse rather than an aeronautical facility.
The court held that municipal planning and zoning laws applied and ordered demolition of the structure.
