Re: RRSP Contribution - Canada
You need to make a judgement as to the likely tax rate upon withdrawal at age 69. If it is less than his current tax rate, then it is a good deal. If it is equal then there in NO advantage to an RRSP. With inflation, the odds of tax rate creep are very high so it is highly unlikely that it is tax advantageous.
RRSP contributions work best when you are at your peak earning years in your 40s and 50s when your tax rate is very high.
