Appeals concerning whether labour relations at a provincially owned utility's nuclear generating stations were governed by provincial or federal labour legislation.
The majority held that Parliament's declaratory power under s. 92(10)(c) and s. 91(29) validly brought the nuclear facilities within exclusive federal jurisdiction, and that labour relations were integral to the operation and management of those declared works.
A majority also held that atomic energy is a matter of national concern under the peace, order and good government power, and that labour relations at the nuclear facilities formed part of that jurisdiction.
The argument that provincial authority over electrical generation under s. 92A(1)(c) displaced federal authority was rejected.
The appeals were dismissed and the Canada Labour Code was held to apply to employees employed on or in connection with the nuclear facilities.
