The complainant union (CUPE) alleged that the respondent university violated section 64 of the Labour Relations Act by prohibiting the University of Toronto Staff Association (UTSA) from using the university's internal mail service to distribute CUPE organizing materials.
UTSA had historically enjoyed unrestricted access to the mail system.
The university argued that permitting the distribution of union organizing materials would constitute employer support for a trade union, violating sections 13 and 64 of the Act.
The Board held that the university's restriction of an existing practice constituted interference with the union's rights.
The Board declared a violation of section 64 and directed the university to permit UTSA access to the internal mail service in the manner previously enjoyed.
