Okay. Thanks.
The Auditor General might like to respond to this, but perhaps the department representatives could speak to this. The report talks about regulating, monitoring, enforcing, and assessing environmental impacts on the Northwest Territories, but doesn't necessarily specifically talk about also regulating, assessing, and monitoring impacts, including cumulative impacts, of sources of external pollution.
The parliamentary secretary referenced the buildup of heavy metals in the Arctic, which I'm well aware of from my work at the CEC, and Mr. Vaughan would be as well, but there is also a growing accumulation of emissions coming from activities in northern Alberta, and if the tar sands pick up in Saskatchewan.... Downwind of the tar sands, we've received information, a review of oil sands and water, a submission of information. I'm wondering if Ms. Fraser would like to respond to that and if that's an aspect they considered or might want to look at if it wasn't specifically looked at.
But I'd like to hear from the agencies. Do they regularly intervene in tar sands applications, for example, like, say, the site C dam that's being expanded? We heard witnesses from the Northwest Territories to that effect: first nations are very concerned about the potential and growing level of pollutants, both airborne and waterborne, through the Mackenzie Basin region.
