The appellants challenged the jurisdiction of the Alberta Energy Resources Conservation Board to entertain an application by Calgary Power Ltd. for the construction of an electrical transmission line to the Alberta-British Columbia border, intended to interconnect with a line in British Columbia.
The Supreme Court of Canada held that, in the absence of federal legislation regulating the interconnection, the provincial board had the constitutional authority to approve the intraprovincial construction and operation of the facilities, as they constituted a local work and undertaking under s. 92(10)(a) of the British North America Act.
