Is it more advantageous for you to save money for your retirement or pay down your mortgage? It all depends on your personal financial situation. A contribution to a registered retirement savings plan (RRSP) is deductible from your income for tax purposes and is therefore a non-negligible advantage in the short term. And in the long term, an RRSP ensures a more comfortable retirement. However, paying off your mortgage quickly significantly reduces your rental cost and gives you the advantage of financial independence.
