A borrower with a variable rate mortgage sees the Bank of Canada raise interest rates by 0.50%. Their lender uses a 'rate trigger' system. What happens when the monthly payment can no longer cover the interest portion?

Q: What is the correct answer to: A borrower with a variable rate mortgage sees the Bank of Canada raise interest rates by 0.50%. Their lender uses a 'rate trigger' system. What happens when the monthly payment can no longer cover the interest portion?

The correct answer is The borrower must increase their payment or make a lump sum payment. Option B is correct because when a variable rate mortgage hits its trigger rate, creating negative amortization, federal banking regulations and lender policies require borrowers to take corrective action. The borrower must either increase their monthly payment to cover the full interest amount or make a lump sum payment to reduce the principal balance enough to restore positive amortization. This prevents the mortgage balance from growing indefinitely and protects both parties from excessive risk accumulation.

Q: What background knowledge is needed for this Mortgage & Real Estate Finance question?

Variable rate mortgages in Canada typically feature either adjustable payments that change with rate fluctuations, or fixed payments with adjustable amortization periods. The trigger rate system uses fixed payments until rates rise to where payments no longer cover interest. At this trigger point, negative amortization begins, meaning the mortgage balance grows monthly. Federal banking regulations and OSFI guidelines require lenders to have mechanisms preventing unlimited negative amortization. Most lenders set trigger rates and require borrower action when reached to maintain loan performance and regulatory compliance.

Q: What is a good way to remember the answer to this Mortgage & Real Estate Finance question?

Think 'TRIGGER = Take Responsibility, Increase Greatly or Give Extra Relief'. When you hit the trigger rate, you must TAKE action by either INCREASING payments GREATLY or GIVING EXTRA money as a lump sum to get RELIEF from negative amortization. When you see trigger rate questions, remember that hitting the trigger always requires borrower ACTION - either payment increase or lump sum. The lender doesn't automatically fix it for you.

Q: What exam tip applies to this Mortgage & Real Estate Finance question?

Look for 'trigger rate' in variable mortgage questions. The answer will always involve borrower action (payment increase or lump sum), never automatic lender solutions like renewal, conversion, or extension.

Q: How does this Mortgage & Real Estate Finance concept apply in real world practice?

Sarah has a $400,000 variable rate mortgage with monthly payments of $2,100. When the Bank of Canada raises rates by 0.50%, her interest portion rises to $2,200 monthly, exceeding her payment by $100. Her lender notifies her that she's hit the trigger rate and must either increase her monthly payment to $2,200+ or make a lump sum payment to reduce the principal enough that $2,100 again covers the interest portion.
