In a system like Quebec's, where all the contractors and all the workers are required to band together, collusion is inevitable. People are forced to get together and have discussions as a family. When you're in a family, you talk and you divvy up the pot. That's what isn't acceptable.
If there's a restriction on the number of shops that can bid—we're getting there in Ontario—on a big project whose general contractor is unionized, then there's a restriction on the number of subcontractors who can bid. And that's collusion.
