The appellants, two cottagers' associations, appealed a decision dismissing their application for a declaration that individual cottage sewage systems were subject to the Building Code Act rather than the Ontario Water Resources Act.
The central issue was whether the relevant "lot or parcel of land" for determining regulatory jurisdiction was the five registered parcels owned by the Grand River Conservation Authority or the individual cottage lots described in leases.
The Court of Appeal upheld the lower court's decision, finding that "lot or parcel of land" means land that is legally recognized for municipal and planning law purposes and for which title can be conveyed.
Since the individual cottage lots were not formally severed or registered, the five registered parcels constituted the relevant "lot or parcel of land," bringing the collective sewage systems (exceeding 10,000 litres per day) under the jurisdiction of the Ministry of the Environment.
