Appeal concerning whether employees of an intraprovincial Alberta short line railway carrying grain to a national railway fell under federal or provincial labour jurisdiction.
The majority held the railway was neither itself an interprovincial undertaking nor sufficiently integrated with a core federal undertaking under the functional integration analysis from the labour jurisdiction jurisprudence.
Physical connection, commercial dependence, and participation in a federally regulated grain transport system were insufficient to constitutionalize the undertaking as federal.
The appeal was allowed, the constitutional question was answered in the negative, and provincial labour jurisdiction applied.
