The applicant union applied for certification to represent employees at the respondent's fish processing plant in Leamington, Ontario.
The respondent challenged the Ontario Labour Relations Board's constitutional jurisdiction, arguing its business was a federal undertaking under the federal fisheries or trade and commerce powers.
The Board held that fish processing is a local undertaking subject to provincial jurisdiction, as it is not an integral part of preserving fisheries as a natural resource, nor is it a core federal trade and commerce undertaking despite its extra-provincial trucking and export activities.
Finding that the union had the requisite membership support, the Board issued a final certificate.
