The primary jurisdiction over fracking is provincial. Environment Canada could have jurisdiction if, for example, there were evidence that substances that had been assessed as toxic and added to schedule 1 of the Canadian Environmental Protection Act were being created or released in a way that created risk to the environment or to human health. Our science colleagues are remaining abreast of the scientific developments with respect to the toxic impact of fracking.
Other than that, it's the result of a local industrial activity that may have some geological impacts. It may have impacts on the water table. We don't have jurisdiction with respect to that. Of course, under the Fisheries Act we have jurisdiction over water that's frequented by fish.
