Saving for retirement is a lengthy process and often involves utilizing contributions to both a registered retirement savings plan (RRSP) and a tax-free savings account (TFSA).

However, statistics show Canadians are saving less than four per cent of their disposable income and, despite the billions of dollars invested in RRSPs and TFSAs, have plenty of room to add more to their retirement nest eggs.
