The applicant trade union sought certification for a unit of employees of the respondent, a company that prepares customers' materials for mailing via Canada Post.
The respondent argued that its labour relations fell under federal jurisdiction pursuant to s. 91(5) of the Constitution Act, 1867, as its operations were an integral part of the postal service.
The Board rejected this argument, finding that the respondent acted as a mail service broker and its operations were not an essential or integral part of Canada Post's core federal undertaking.
Having asserted provincial jurisdiction, the Board found the proposed bargaining unit appropriate and, based on the membership evidence, issued a certificate to the applicant.
