CPP? Here in Canada, nobody thinks CPP is a source of income after retirement. Also, when you get CPP, you have to pay tax on that. So the actual money you receive would be tiny.
You should definitely consider other source of income for the future. I personally don’t think RRSP is a good idea. It is like throwing money in the toilet. RRSP is suitable for the people who don’t know anything about investing their own money.
