The solutions that we think respond to your question would be to get more people into pension plans. Generally, the Canadian public is very badly served by the RRSP pension system: most people can't use it; they pay very high fees; when they get into later career after they've gone through a period of doing child care or what have you, they often can't save enough; if they've lost money in the markets, they can't contribute more to catch up.
There are things we can do to our retirement savings system to make pension plan membership or at least membership in a plan where you get better management of the money and more opportunity to contribute. There's a lot that can be done there, and it doesn't just apply to women; it applies to almost everybody in the private sector workforce.
