Secondary Suite Financing

Tracy Head • October 18, 2024

Mortgage rule changes seem to be coming at us fast and furious. This isn’t surprising given we are in an election year.

Several weeks ago I wrote about the change to the ceiling for the purchase price of insured homes and the extended amortization that will be available.


On October 8, 2024 the government announced a new program that will come into effect January 15, 2025.

The new program will enable clients who already own their homes to refinance up to 90 per cent of the value of the home to use the available equity to create a secondary suite.


Current rules only allow refinances up to 80 per cent of the value of the home, regardless of the purpose of the refinance.


The parameters of this new program, taken directly from the CMHC website (Mortgage Insurance Rule Changes to Enable Homeowners to Add Secondary Suites  - Canada.ca) are as follows:

  • This measure will apply to all borrowers seeking to access mortgage insurance in Canada to add more units (secondary suites). These borrowers must satisfy the following requirements:
  • Already own their properties;
  • The borrower or a close relative are occupying one of the current units;
  • Intend to construct additional units; and,
  • The additional unit(s) must not be used as a short-term rental.
  • Refinancing: Insured refinancing will be allowed for the purpose of building additional unit(s).
  • Legal units: The new units must be fully self-contained units (e.g., basement suites with separate entrances, laneway homes) and meet municipal zoning requirements.
  • Number of units: Maximum of four dwelling units including the existing unit.
  • Maximum Property Value Limit: The “as improved” value of the eligible residential property against which the loan is secured must be less than $2 million.
  • Maximum Loan-to-Value limit: Up to 90 per cent of the property value, including the value added by the secondary suite(s), in combination with any other outstanding loans secured by the property.
  • Maximum amortization: 30 years.
  • Additional financing must not exceed the project costs.


We are still waiting on clarification from lenders as to their specific guidelines around this program so I will provide more information as it becomes available. 


With respect to what this means in dollars and cents, using a home valued at $800,000 we will now be able to refinance up to $720,000 for the purpose of adding an additional legal suite. Under previous guidelines we would only be able to refinance up to $640,000 so in this example clients will be able to access $80,000 more of the equity in their home.


It will be interesting to see what the uptake is for this program. 


One particular group of clients I see this benefitting is clients who have only been in their home a few years that have seen a moderate growth in their equity after only having put down the minimum down payment when they purchased their home.


With carrying a higher mortgage and the increased cost of living overall these clients may really benefit from access to funds to add a secondary suite to their home.

Its been a while since I wrote about the importance of your credit report. This topic popped up twice this week so I think a refresher is not a bad idea. When we submit a mortgage application lenders look carefully for a few specific things: Is the home you are looking to buy or refinance readily marketable / appeals to a wide range of potential buyers? Do you have your down payment in order? Do you have consistent income to repay your mortgage? Does your overall financial profile show you manage yourself responsibly? Does your credit report reflect a history of payments made on time and as agreed? When they are reviewing your credit report they are also looking for a few specific things. How long have you had active credit facilities (credit card/line of credit/mortgage etc)? Do you have a history of making your payments on time? Do you pay most of your credit card balances off regularly or do you run with cards maxed out all the time? Lenders fully understand that sometimes life happens and we can sometimes explain one-off blips or issues. If you have a consistent history of late payments that can become a bit more challenging to explain. One thing that I chat about with my clients is how making your credit card payment a few days ahead of your statement cutoff date can really help boost your score. Over the last few years it has become more common that people use their points cards for everything over the course of the month then pay their card in full once they get their statement. If you operate your credit card this way your credit report only picks up the balance as reported on your statement so it can look like you are always carrying a significant balance even though you always pay in full. For most people this is not a big deal, but if you are working on improving your credit score this small tweak can have a huge impact. The other issue that popped up this week was incorrect information on a client’s credit report. Part of her first name was missing and the birthdate was incorrect. The client was able to confirm everything on her credit bureau for me right down to previous addresses, employers, and old loans that had been paid off. Lenders would not move forward until her credit report was corrected and in this case because two items were wrong the client needs to correct it herself (normally we can help make changes fairly quickly). Its always a good idea to review your credit report at least once a year to make sure that all of your information is reporting correctly. If there is an issue you can catch it early and correct it before you are in a panic midway through a mortgage application. Changing topic a wee bit as my daughters are on evacuation alert already … If you are in the process of buying a home as we move into fire season please make sure you have a clause in the agreement as to what will happen should there be an active fire nearby. Nail down your home insurance as early as possible because once there is an active fire close by securing an insurance policy can be very difficult if not impossible.
