We have a range of regulations that specify what the acceptable levels are in terms of migratable amounts from paint and other things like that. The minister has also committed to come forward with an integrated strategy on lead and a number of regulations to respond to this particular issue.
But more fundamentally, the idea is not to go at things one substance at a time. With respect, as a bureaucrat, I think that would doom us to fail, because we can't keep up. Industry has a new product, a new technology, a new substance around the corner. The general prohibition allows us a more flexible response, rather than trying to keep up with this thing one substance at a time. Rather than placing the heavy burden and onus on us to do all of the science, the onus is on industry to prove the product is safe.
