wsib I beleive that WSIB is Ontario's version of the workmen's compensation board. We in Quebec have the C.S.S.T. which is equivalent if not worse. Unfortunatly the CSST does not give out letters of good standing. Although I know of no hold back system inj Quebec, that compares to what often happens in Ontario, where employers of sub contarctor's hold back up to 20% if the letter of good standing is not provided. I would imagine every Province has their equivalent board.
