The applicant trade unions sought declarations under sections 1(4) and 64 of the Labour Relations Act that the various PCL corporate entities constituted a single employer or that a sale of a business had occurred between them.
The Board found that the PCL family of companies operated as a single integrated business enterprise under common control and direction, with centralized management, human resources, and labour relations functions.
The Board also found that corporate reorganizations in 1978 and 1984 constituted sales of a business.
The Board rejected the responding parties' arguments that the unions had abandoned their bargaining rights or unduly delayed in asserting them.
The Board granted the declarations, binding the PCL entities to the applicable provincial collective agreements, effective May 11, 1994, exempting projects contracted prior to that date.
