You could keep it, it would just suck. Sell everything you can ( bike, non registered investments, tfsa, etc) to take six figures off your mortgage. Instead of investing new money, dump it in the mortgage. By the time you get to renewal, you should be able to make the minimum payments, vacations are off the table until rates drop.A rise to 10% interest rate would effectively make my own home unaffordable. Even if I was fixed today....it would come up around the time this massive rise will go up.
