The applicant trade union applied for certification.
Following a representation vote where more than 50 per cent of the ballots were cast in favour of the union, and with no statements of desire to make representations filed, the Ontario Labour Relations Board issued certificates to the union.
The certificates cover plumbers, steamfitters, and their apprentices employed by the responding party in the industrial, commercial, and institutional sector province-wide, and in all other sectors in the City of Ottawa and the United Counties of Prescott and Russell.
