I want to ask a question about what I see as a short-term challenge and a medium-term opportunity: the fact that Canada's infrastructure for generating power is aging, and there's going to be a very great degree of turnover in the next number of years, particularly from about 2010 to 2012. It provides a short-term challenge because it's hard to drive down emissions when we still have those facilities operating, but it creates a medium-term opportunity in that if we replace those facilities with clean facilities or methods of generating power that substantially reduce emissions in that timeframe, it can have a very large impact.
How important is it for the government to establish firm emissions caps, if you will, to drive that change? What action does the government need to make sure a clear signal is sent to industry that when that turnover is taking place, the replacements will be the types of energy creation that are going to substantially reduce emissions?
It's a general question to those on the panel who would want to answer.
