First of all, and I think you're inferring it in your question, in Canada, we have a legal framework that respects all of our trade agreements, and we operate in that sense.
The other piece I would have to say is that we already source domestically. Over the average of five years, $14.3 billion of procurement has been run through Public Works and Government Services. Of that, $12 billion is already going through Canadian domestic procurements. So it is a large proportion already.
With regard to trade agreement provisions, certainly once you've reached the trade limit, it is open under NAFTA. It's open under the free trade agreement with Columbia. It is open to the various free trade groups we have in place.
I would have to say that the method we approach procurement with has a significant impact domestically in Canada. It is through low-dollar-value procurements and through specific procurements that are targeted for the Canadian market under various exemptions. That, to me, is an example.
I can't comment on the policy objectives, of course, but certainly with the structure we have, the net effect is that just under $12 billion of our purchasing is sourced domestically in Canada.
