That's correct. There is what you'd call wall-to-wall unions in construction in this country. For example, in Saskatchewan, the CEP, the Communications, Energy and Paperworkers Union, can now operate in competition with the building trades. The Christian Labour Association of Canada can do the same.
Building trades unions are based on the hockey theme that if you're a right winger, you'd never go into your own end zone to help out your defenceman. You'd just stay there and say you're on right wing. I don't think any union boss would play hockey that way, and I don't think our construction sites should be entirely done that way any more.
So, barring CLAC and CEP—which they are doing in some parts of this country, like in Nova Scotia entirely—leads to less competitive behaviours. We need to drive change in the building trades unions in this country, and competition will do it.
