Thank you for the question, Ms. Collins.
There is already an obligation in section 71 of CEPA. It's an authorization whereby the minister may impose a testing obligation in particular circumstances. There's a second section, section 72, which provides an impediment to the minister requesting the testing.
That's part of the statutory problem that needs to be corrected. It's not corrected by Bill S-5. It is corrected by our proposed amendments, and they can be found at tab five of our proposed amendments.
The long and short of it is that the minister has the discretion to do so now, but rarely does, in part because of section 72. These two sections need to be amended so that whenever the minister is uncertain as to whether a substance is toxic or capable of becoming toxic in the circumstances that are described in Bill S-5, there is a mandatory obligation on the minister to require the testing. That can happen one of two ways. Either require industry to do the testing, or else require that industry pay for testing that's conducted, either by the government or by an outside, independent laboratory.
