The applicant union referred a grievance to the Board under section 112a of the Labour Relations Act.
The respondent employer raised a preliminary objection, arguing it was not bound by any collective agreement with the applicant.
The Board found that in November 1974, the respondent's site supervisor signed a collective agreement with the union.
Although the supervisor lacked actual authority to bind the respondent, he had apparent authority.
Furthermore, the respondent's subsequent conduct over three years—hiring union carpenters, paying union wages, and making required remittances—constituted ratification of the agreement.
The Board concluded the respondent was bound by the provincial collective agreement and remained seized of the grievance.
