The challenge you pose is that it's hard enough getting the resources, as has been raised in this committee, to enforce the legislation in the first place. To then get the money for surveillance to ensure you can actually draw some connection between the two is even more difficult, especially since there are a number of other exposures that contribute. So actually attributing it is a huge challenge, not that we shouldn't be trying to do it. I note that for the first time in history Canada is beginning to develop an environmental and occupational exposure surveillance, and we've been having this problem for much longer. So I think that's part of the problem.
The other part of the problem is that consumer protection is more of a rights-based approach driven by concern for health but feeding into the rights of people to make a decision, which is fundamental to a free market economy.
