The Minister of Labour referred a question to the Ontario Labour Relations Board regarding whether the labour relations of Transit Windsor fall under provincial or federal jurisdiction, following the union's request for a conciliation officer.
Transit Windsor operates a municipal transit system but also runs a regular and continuous extra-provincial bus service to Detroit, Michigan.
Applying constitutional principles, the Board determined that the extra-provincial services, though comprising only 3% of total working hours, constituted a continuous and regular part of an indivisible undertaking.
Consequently, the Board advised the Minister that the labour relations between the parties fall within federal jurisdiction.
