Well, sir, when you're talking about the potential of the economy and its growth rate, you are really talking about either labour supply or productivity. In terms of labour supply growth, because of the aging demographics, you are going to see a reduction in the growth rate in labour supply. In terms of productivity over the past ten years, we have seen very low productivity in Canada, something in the neighbourhood of 0.7% when you look at real output relative to man-hours. We're assuming we can still bump that back up to its long-term trend of 1.2% over the next five years. Actually, we use that assumption going forward. So we would be happy to come back and talk to you about strategies the government can look at to boost productivity, but obviously that is going to be key.
Canada's potential growth rate is falling particularly because we've seen reductions in Canada's productivity rate over the past ten years, and labour supply numbers and growth rates are coming down.
