Over the course of the next 20 years, nearly 7 million Canadians will retire, a considerable portion with the benefit of a pension plan; some with defined benefit plans, others with annuities purchased with the funds they receive from a defined contribution plan. The sustainability of those plans, however, faces an uncertain future, as exemplified by the bankruptcy or insolvency proceedings concerning Indalex, Nortel and most recently, for the second time, U.S. Steel Canada (previously Stelco).
