Pursuant to Section 153 of the Labour Relations Act, 1995 (and predecessor legislation). As of July 1, 2010 the Minister of Labour, Immigration, Training and Skills Development (not the Ontario Labour Relations Board) may designate employee and employer bargaining agencies in the construction industry in Ontario. The Minister may also revoke or amend such designations. Nevertheless, the Minister may refer to the OLRB any question with respect to a designation and the Board shall report its decision on the question to the Minister.
Employee bargaining agencies are designated to represent provincial units of affiliated bargaining agents, and the Minister may describe the provincial unit.
The Minister may also designate an employer bargaining agency and describe the provincial unit, even if an employers' organization has been accredited as a bargaining agent.
These Ministerial designations reflect pre-existing bargaining patterns and do not necessarily correspond to craft or trade lines.
Below is an index of these designations in alphabetical order by trade. Click on an index entry to go to the designation itself. For the sake of completeness all designations are included here even if they have been revoked or amended, so pay special attention to the notes (such as "Amendment" or "Revokes & replaces earlier ones") in the document titles. For Bargaining Agency Designations please contact the library owtl@wsiat.ca for copies.
