Thanks very much, Mr. Savard-Tremblay.
We talked about the steelworkers recently. The steelworkers have done some good work on this through Blue Green Canada. They have a proposal for sustainable purchasing at multiple levels of government. It would factor in things like the carbon emissions of Canadian cement versus those of international cement or steel or aluminum. As the committee has heard, we have some of the cleanest aluminum and steel in the world. Applying those kinds of criteria would in effect favour local production, local jobs and local workers, without running afoul of our trade obligations, which, as I think you know, currently prohibit those kinds of clauses.
That's one angle that I think we could think about in terms of sustainability criteria versus having explicit buy local or buy Canadian criteria, which are prohibited under a lot of Canadian trade deals.
