I appreciate the question, and certainly the polluter-pay principle exists in common law and it's resident, I think, in a number of different pieces of legislation.
In the particular instance here, the context around polluter pays is one in which there seemed to be a limit to which the community could operate, and that limit is not constrained in a Canadian context but is a global issue. Certainly, the aspects of the bill demonstrate that the polluter will pay and the polluter will be held accountable.
