The applicant employer sought judicial review of an Ontario Labour Relations Board decision certifying a union as the exclusive bargaining agent for a construction industry bargaining unit.
The core issue was whether two employees performed construction industry work on the application date.
The Divisional Court found the Board's conclusion that disconnecting a pump for off-site repair constituted construction work 'at the site' to be unreasonable.
However, the Court upheld the Board's finding that replacing a thermal sensor constituted repair work, as it was a reasonable, fact-driven conclusion owed deference.
Consequently, the application for judicial review was dismissed.
