Open Mortgages: What They Are and When to Use Them

Tim Lyon • September 18, 2025

What is an Open Mortgage?

In Canada, most mortgages are "closed" mortgages, meaning you'll face a penalty if you want to pay them off early. An open mortgage is different - it can be paid off at any time without penalty.


However, this flexibility comes at a cost. Open mortgage rates are significantly higher than closed mortgage rates because lenders need to account for the possibility that you might pay off the entire balance at any time. This makes open mortgages unsuitable as a long-term strategy.


When Open Mortgages Make Sense

There are two main scenarios where an open mortgage can be a smart short-term solution:


Planning to Sell Soon After Renewal

If you're planning to sell your home within a month or so of your renewal date, it makes sense to renew into an open mortgage. This way, when your property sells, you can pay off the mortgage immediately without penalty.


An alternative strategy is to renew your entire mortgage into a HELOC (Home Equity Line of Credit) if you qualify. A HELOC typically offers a lower rate and requires only interest payments, making it less expensive. However, not every lender offers HELOCs and not every borrower will qualify.


Switching Lenders at Renewal

The most common use case for open mortgages is when switching lenders at renewal. Sometimes its hard to make the dates line up exactly. For example if your renewal date is on a weekend or if you are on vacation or if we need a few extra days to get the new mortgage completed. In these situations, you would instruct your current lender to renew your mortgage into an open mortgage. A few days later, when we complete the switch to your new lender, the open mortgage gets paid out without penalty. Although the rate is high, since it's only for a few days, the overall cost remains minimal. 


I actually ask all my clients who are switching lenders at renewal to ask their existing lender to renew their mortgage into an open mortgage, even if we plan to align the dates perfectly. That way if there is a slight delay of a day or two they aren’t automatically renewed into a new closed mortgage by the existing lender.


Quick Summary

Key Benefits of Open Mortgages
  • No penalties for early repayment – flexibility to sell or switch anytime
  • Short-term solution for timing issues – useful during renewals and transitions
  • Peace of mind – no risk of being stuck in a costly closed mortgage if plans change suddenly
Important Considerations
  • High rates (often double closed mortgage rates) make them unsuitable for long-term use
  • Limited availability compared to standard closed mortgages
  • Best used strategically for short-term situations like selling or switching lenders


Example

Imagine your mortgage is up for renewal, but you’re switching lenders and the process runs a few days past your renewal date.

  • If you renew into a closed mortgage with your current lender, you could face penalties when you switch a few days later.
  • If you renew into an open mortgage, you pay a slightly higher rate for those few days but avoid penalties altogether.

If you own a property with a mortgage, you've probably heard the terms "renewal" and "refinance" thrown around. While both involve obtaining a new term for your mortgage, there are some important differences to understand. Let's break down what each one means and when you might use them. Understanding Mortgage Basics In Canada, when you take out a mortgage, the payments are typically spread over 25 to 30 years. This period is known as the amortization. However, unlike in the U.S., Canadians do not keep the same interest rate and payment terms for the entire amortization period. Instead, you have an initial term, usually 3 to 5 years, after which you need to renew into a new term. For example, if you have a 25-year mortgage with 5-year terms, you will need to renew your mortgage four times throughout its lifespan. It's also common to have a mix of different term lengths over the course of your mortgage. What is a Mortgage Renewal? A mortgage renewal occurs at the end of your mortgage term. When you renew, you start a new term with a new interest rate while keeping the remaining details of your mortgage the same. The key element here is that the mortgage charge registered on your property's title remains unchanged. A renewal is straightforward and typically does not involve any significant changes to your mortgage agreement other than a new interest rate. Think of it as hitting the "continue" button on your mortgage, but at new rates. What is a Mortgage Refinance? A mortgage refinance is different. When you refinance, you are making changes to your original mortgage agreement. This means paying off your existing mortgage and registering a new one on your property's title. Essentially, you are taking out a completely new mortgage for the same property. People commonly refinance to: Access the equity in their home for investments or major purchases Consolidate high-interest debt into their lower-rate mortgage Extend the amortization period to reduce monthly payments and improve cash flow Make significant changes to their mortgage structure It's important to note that refinancing is not allowed for insured properties (those with less than a 20% down payment at purchase). This means the maximum loan amount in a refinance is 80% of your property value. What About Switching Lenders? If you want to keep everything the same but switch lenders for a better rate, this is known as a transfer. A transfer is a type of renewal where the original mortgage charge is transferred from one lender to another. Depending on the lenders involved, you might be able to make minor changes (like extending the amortization or changing borrowers) without needing a full refinance. Why Timing Matters Your mortgage maturity date is when your current term ends. This is the ideal time to either renew or refinance. If you refinance or switch lenders before the maturity date, you will face a prepayment penalty. If you refinance, renew or transfer at maturity, there is no penalty. Real-World Example A homeowner with a $450,000 mortgage is reaching the end of their 5-year term. Their lender offers a renewal rate, but they also have $40,000 in high-interest credit card debt. Option 1: Renewal They accept the new term. Their mortgage stays the same. Their debt remains separate at high interest rates. Option 2: Refinance at Maturity They consolidate the credit card debt into the new mortgage. Their total monthly payments drop significantly, even after accounting for the new mortgage balance. In this situation, refinancing provides better cash flow and a simpler payment structure. Quick Summary Mortgage Renewal: Starts a new term for your existing mortgage Mortgage charge on your title stays the same Keeps all other terms the same aside from interest rate Can switch lenders at renewal through a transfer No penalty when done at maturity Mortgage Refinance: Pays off current mortgage and creates a new one New mortgage charge registered on your title Often resets the amortization period Can access equity or make structural changes Maximum 80% of property value for uninsured mortgages Incurs penalty if done before maturity Next Steps Understanding the difference between renewal and refinance helps you make informed decisions about managing your mortgage.
