I think part of the problem we're facing in many countries is there is a shift away from defined benefit to defined contribution schemes. Canada has been a little behind the U.S. and the U.K. in that shift, but the shift is nevertheless going on.
The problem is that we now have defined benefit schemes where the demographics of those schemes is very old. The schemes are closed to new members and they consist of pensioners and older workers. That's very difficult to finance when you don't have ongoing movement and contributions into the schemes. It makes the options very, very difficult when plans are closed to new members or closed to new contributions from existing members, as many plans have become.
It is a very difficult problem. In the long term, when we have defined contribution schemes, this problem does not arise. People have their individual accounts.
