The applicant union applied under section 1(4) of the Labour Relations Act for a declaration that the respondents, Century Store Fixtures Ltd., Century Interiors Ltd., and Jasper Construction Inc., be treated as one employer.
The union argued that Century, a unionized interior contractor, engaged in general contracting when its carpenters worked on Jasper's sites under Jasper's direction.
The Board found that Century and Jasper operated in different markets and were not engaged in associated or related activities.
The Board concluded there was no erosion of bargaining rights, as the carpenters were covered by the collective agreement at all times, and dismissed the application.
