I agree that the enforcement components could be difficult to achieve for a couple of reasons. One, those federal acts cited are the responsibilities of other ministers, not the lead minister for this bill, so it would really require their involvement in terms of any enforcement along those lines.
As well, to point to the references to international agreements, those would also be with different nation states. There might be specific enforcement mechanisms built into those agreements, and there would be a lot of dependencies on where this act could impose changes on another nation state, for instance.
