It's a good question. I've said I'm not commenting on the specific legislation you referred to, but I'll just take it first from a medium-term perspective and reference something I tried to say earlier, which is that the contribution of labour supply--people working, but also hours worked--has been the dominant contributor to real GDP growth over the course of this decade.
We are in a situation, as I think everyone knows, in which the participation rate in our economy is at an historic high, unemployment is very near a 33-year low, and we also have demographic factors that are starting to impact. And as I said earlier, in order to maintain what has been the average growth rate--a little north of 3%--real growth rate over the course of the 15-year expansion we're in, productivity growth is going to have to accelerate markedly, because that labour supply is going to go from contributing about 1.6% a year, which has been the average, to about 1% by 2010. Our estimate, I believe, is 0.8% by 2015. So for 0.8% to contribute to 3%, you see where productivity has to shoot up.
Whether we can materially alter that profile is one of the questions. It will be difficult, but the factors that would change that profile would include encouraging and incentivizing older Canadians to work longer, continuing to enhance flexibility within the economy so people can move to jobs, and recognizing their training so that people remain able to move to jobs. Immigration has a potential role to play there as well. There are a variety of factors that have an impact on what is an important medium-term shift in labour supply in this economy.
