Please, everyone, do yourself a favor and talk to a financial advisor. Most people have very different expectations for retirement, a financial advisor is the only one qualified to help you.
For me, I'm 43, DW is 39, we have 3 daughters, 16, 14 and 12. For many years we only contributed to my RSP. We weren't doing enough to save for retirement and it looked like we would not be able to retire until we were 65. 5 years ago the company I work for started an RSP matching program, so I jumped at the opportunity and took advantage of it by maxing out what they would match. A year later my wife starting working for the same company and she took advantage of the max RSP matching as well.
That was great, but by far our best retirement advice came from a financial advisor we met with 3 1/2 years ago. We were 3 years from paying off our house. He suggested we get involved in an investment plan that would take advantage of two key strategies: 1. use the equity in our house to invest, and, 2. Use that investment to pay down the mortgage faster, but more importantly, essentially allow us to make our "mortgage" payment tax-deductible.
This is a strategy that I was very skeptical about. However, after three years I can conclusively state it is by far our best investment decision to date. Our house was paid off faster using the strategy, and we are now looking at being able to retire by the age of 55, instead of 65.
If anyone is interested, google "Smith Manoeuvre". But, as I already stated, please talk to a financial advisor.
