Board refuses extrinsic evidence to expand non-construction collective agreement to cover construction bricklayers.
The applicant union applied for certification of a bargaining unit of bricklayers and stonemasons employed by the respondent municipality.
The respondent argued that an existing collective agreement with the intervener union covered these employees and acted as a bar to the application, seeking to introduce extrinsic evidence of negotiations to prove this intent.
The Board held that the collective agreement, which defined employees as those on the active payroll and lacked construction industry provisions, clearly did not cover construction bricklayers.
Finding no patent or latent ambiguity in the agreement, the Board refused to admit the extrinsic evidence.
