Couple approaching 65 with a mortgage worry tariff war will torpedo retirement

Patricia earns about $70,000 a year before tax and Craig earns about $110,000 annually before tax. Both Patricia and Craig have employer pension plans that are indexed to inflation. If they retire as planned at 65, Patricia will receive $20,000 a year and Craig will receive $10,000 annually. Their anticipated Old Age Security benefits at 65 will bring in another combined $10,000 ($5,000 each) annually. At this point, they think it’s best to start Canada Pension Plan (CPP) benefits at age 70, which should increase their annual income by $15,600 for Patricia and $16,800 for Craig. Is this a good strategy?
