The applicant trade union applied for certification to represent a bargaining unit of service employees at Markham Stouffville Hospital.
The responding party disputed the applicant's estimate of the number of employees and proposed a different bargaining unit, giving notice under section 8.1 of the Labour Relations Act, 1995.
The Board found that the applicant established sufficient membership support to obtain a representation vote.
The Board ordered a representation vote to be held, with the ballot box sealed pending resolution of the bargaining unit description dispute.
