I think I'd go back to some of the points that Daniel made earlier.
I'm not as familiar with the Australian system...or I've lost a lot of my recollection of the Australian system, but they do use temporary workers fairly extensively.
But immigration is not just about skilled workers. We have an immigration movement that is multi-faceted. The economic component is a significant component of the skilled worker component, but we also have a family class movement. We also have a refugee movement. We have people who arrive as refugee claimants who are also working in the labour market. So I think looking at it holistically, we need to consider that newcomers to Canada come through different avenues, and it's not only through the skilled worker movement that they enter the labour market.
