If it pleases the chair, just briefly, with different pieces of legislation, Canada has had different types of experience. Under CEPA, for example, our new substances notification program is viewed around the world as one of the strongest pieces of legislation for dealing with new products. Based on the success we've had with that, we're able to negotiate cooperative agreements for information sharing with other countries through CEPA.
On existing substances, the progress you mentioned earlier has had a lot to do with the Pest Management Regulatory Agency's attempting to reach similar types of reciprocal agreements with other countries to speed up the assessment process.
Finally, any regulatory action that is taken has to be accompanied by what is called a RIA, a regulatory initiative impact assessment, which tries to balance off the initiative, the concerns for the environment, for health, and the economy.
The final point I would make is that the ultimate answer is the government's approach to dealing with sustainable development, something that all departments are attempting to contribute to.
