I thank the honourable member for the question.
The control around approved products in Canada rests with our colleagues at Health Canada. However, in terms of our oversight responsibility at the CFIA, it focuses on the food product. Canada does not determine what another country might do in terms of the product it chooses to approve; however, for products that are not permitted in Canada, Health Canada, in addition to making their decision, establishes what is called a maximum residue limit.
That maximum residue limit is established even for products that are not permitted in Canada. In essence, it sets the level of, for example, a chemical residue above which there are human health concerns. Our responsibility at the CFIA, through our monitoring program—the chemical residue monitoring program—would be to assess products, including imported products, to assure ourselves that those products do not contain residues above that maximum residue limit.
It is through the maximum residue limits that are established in Health Canada standards that we've provided the controls to assure Canadians that they're not exposed to products that Health Canada does not believe are acceptable in terms of human exposure.
