Thank you very much, Mr. Chair.
Thanks to all the witnesses for being here.
My questions will be similar to those of my colleague Mr. Tolmie. The first one is more for Mr. Cain, but perhaps for Mr. Carreau as well.
Before determining whether a site is contaminated, first you have to identify the contaminant. In many cases, when people use a product, they don't yet know that it's a contaminant.
I'd like to know if you have access to a list of all the chemicals that may have been used in the course of a year at a given site, or whether there's an obligation to give you access to such a list. By that I mean a registry that can subsequently be used to confirm whether a site is contaminated, in the same way as you can issue recalls of certain products. You know to whom the product was sold and can issue a recall notice.
Does that kind of system exist for the purpose of managing contaminated sites?
