If I may, I hope I didn't give the impression that we would favour targeting industrial policy to particular companies or sectors. I think the most effective approach from a policy point of view is to create the right conditions to make Canada a great place in which to do business and from which to do business globally. Frankly, I think most of the things that are going to be effective on that scale are cross-cutting and not targeted at specific sectors.
That said, I think we do have to be aware of all the economic theory around cluster effects and things like that. The fact is, like-minded people like to hang around together. We know that the Silicon Valleys of the world exist, and they're effective because there are clusters of particular kinds of expertise that group together.
I'm not sure how much governments can do to try to determine where clusters are going to form or whether we should be trying to get clusters of particular things.
