I just have one comment. Salt is kind of in limbo. It hasn't been listed; there's a recommendation made, but it hasn't been listed. What we've heard from people, though, is that if it were listed there would be a lot of pressure to stop using salt in some places, even though that's not Environment Canada's intent.
But one other thing we're seeing is that people are recommending substitutes for salt, and these substitutes haven't been put through a rigorous PSL process. It's moving people away from this product to this product, and this product hasn't been tested either. That's one thing that I think probably would happen in other areas too.
