Ontario Hydro v. Ontario (Labour Relations Board), [1993] 3 SCR 327 -- summary under Subsection 132(6)

The regulation of labour relations was found by the majority to be an integral part of Ontario Hydro's nuclear power generating enterprise, which previously had been declared under s. 92(10)(c) of the Constitution Act, 1867 to be a work within federal jurisdiction. After referring to an argument that earlier cited decisions were confined to "undertakings" in ss. 92(10)(a) and (b) and not to works in s. 92(10)(c), La Forest J indicated (at p. 368) that it was not necessary for him to engage in a consideration of the possible differences in scope between an "undertaking" and a "work" given that the latter meant "a work as a going concern," so that both concepts extended to management-labour relations.
