Mortgage Default Insurance

Helping Canadians Finance Their Homes


Yes, in Canada, you need to have a down payment to purchase a house. Lenders require you to have some ‘skin-in-the-game’ in the form of a down payment.


To get a conventional mortgage you need a down payment of 20%, meaning that 20% of the properties value must be covered by you via your down payment. The lender can then finance up to 80%.



A 20% down payment is a significant sum. Fortunately, for most of you just starting out on your journey to acquire a home and establish a financial base, there is mortgage default insurance. With mortgage default insurance in place, it is possible to obtain a mortgage on your home with a down payment as small as 5% of the property’s value.

What is Mortgage Default Insurance?


Mortgage default insurance is an insurance policy that protects your mortgage lender against loss if you default on your mortgage. If a lender is unable to recover the remaining amount of a mortgage owing to them after a borrower has defaulted, the insurance covers the shortfall or loss.


Mortgage default insurance is important to the functioning of the Canadian mortgage market. Any mortgage with a loan-to-value (LTV) ratio above 80% that is originated or funded by a federally regulated financial institution must be covered by mortgage default insurance. The LTV ratio is the mortgage balance divided by the property value.


Note that mortgage default insurance does not provide protection for borrowers. This does not mean the borrowers don’t benefit. It would be difficult to find a mortgage in Canada without a 20% downpayment if it wasn’t for mortgage default insurance.


What is the Required Down Payment?


The minimum required down payment is 5% for a home with a purchase price of $500,000 or less. When the purchase price is above $500,000, the required down payment is 5% for the first $500,000 and 10% for the remaining balance, provided the purchase price/value of the property is less than $1,000,000.



  • Properties worth more than $1,000,000 are not eligible for mortgage default insurance and the required down payment is 20%.

Who Provides Mortgage Default Insurance?


The Canada Mortgage and Housing Corporation (CMHC) is the main provider of mortgage default insurance and the key driver of this segment of the market. CMHC is a crown corporation and sets the rules. There are two other significant providers, Sagen (previously called Genworth Financial) and Canada Guaranty, that are both private companies.



Recent changes to the Government of Canada’s appetite for housing risk has led to CMHC taking a declining share of the market, to the benefit of Sagen and Canada Guaranty. These two companies have their own underwriting policies and there are some differences between them, but most borrowers won’t notice the differences. Suffice to say, if your down payment is less than 20%, you should be happy to obtain mortgage default insurance from any of these three insurance providers.

How Do You Qualify for Mortgage Default Insurance?


While every lender and every insurer in the market crafts their own underwriting criteria, the criteria are generally very homogenous. Some differences exist, but for most material underwriting policy criteria, they are all the same. The lenders consider the underwriting criteria of the insurers when they create their own underwriting policies. They may at times be stricter than the insurers and other times may have products that are 100% in line with insurer criteria.


When you apply for a mortgage with a down payment of less than 20%, you don’t interact with the insurer. The lender does the work – they are the beneficiaries of these insurance policies after all. The lender will underwrite your mortgage application with their requirements and the requirements of the insurer considered. The lender submits an application to the insurer as part of their underwriting process and receives confirmation back from the insurer if the application is approved.


What are the Key Criteria?


To qualify for mortgage default insurance with CMHC, you’ll need to meet these criteria:


  • The value of the property being financed must be less than $1,000,000,
  • The amortization period must be no greater than 25 years,
  • Your gross debt service (GDS) ratio cannot be greater than 39%,
  • Your total debt service (TDS) ratio cannot be greater than 44%,
  • Investment properties are ineligible,
  • At least one borrower must have a minimum credit score of 600,
  • Your down payment must come from your own funds. In other words, if you borrow the money for your down payment, you won’t qualify for a CMHC-insured mortgage.



Note that at Sagen and Canada Guarantee some of these criteria may differ. For instance, these private insurers may offer programs for borrowed down payments or insurance for investment properties, although some restrictions apply.

Who Pays and What Does Mortgage Default Insurance Cost?


To obtain mortgage default insurance a lender must pay a premium to the insurer. If you have a high-ratio mortgage that requires insurance, the cost of that insurance premium is passed on to you. In other words, if you want a mortgage when you have less than a 20% down payment, you pay for the insurance.


Most of the time the amount of the insurance premium is added to the mortgage balance. When doing this you are effectively borrowing the funds for the premium at the mortgage rate and paying it back over time. The alternative to that is to pay the entire premium at the closing of the mortgage but that may not be desirable because the premiums can be large. The premium for mortgage default insurance is based on the size of the mortgage and the LTV. The larger the down payment you provide, the lower the LTV and the lower the premium. The premiums, calculated as a percentage of the principal balance of the mortgage, are shown on CMHC’s website as follows:

Note that some special programs may incur higher premiums.


The premium amount is calculated as the applicable percentage from the table above multiplied by the mortgage balance. For example, if you have a $400,000 mortgage with a 5% down payment (i.e.. a 95% LTV) then the premium is 4% x $400,000 = $16,000. This is a material sum, and you can see why most borrowers prefer to include it in the mortgage balance rather than pay it upfront.

You may have noticed that there are insurance premiums for mortgages with LTVs less than 80% in the table above. If your mortgage has an LTV less than 80%, mortgage default insurance is typically not required. However, there are some instances when a buyer with a down payment of more than 20% is required to pay for the insurance. Examples are if the property is in a remote area or a community with just one industry.


The lender may also choose to have a conventional mortgage insured for their own risk management purposes. Lenders refer to such a mortgage as an ‘insurable mortgage’. If a lender does this with a less than 80% LTV mortgage it does not affect the borrower. The lender pays the mortgage default insurance premium and does not pass it on to the borrower.


One last thing to note about pricing is that if you purchase an energy-efficient home or make energy-saving renovations, you could be eligible for a 10% refund on your mortgage insurance premium. For more information, please visit the mortgage default insurers' websites.


PST On Mortgage Default Insurance


Mortgage default insurance premiums in Saskatchewan, Ontario and Quebec are subject to provincial sales tax (PST). The PST must be paid by the borrower at closing because it cannot be added to the mortgage balance. Borrowers in these three Provinces need to take this into account when estimating their mortgage closing costs.

Mortgage Default Insurance Helps New Home Buyers


While there is a substantial cost to mortgage default insurance, the benefits to both borrowers and lenders are significant. Lenders are provided with protection against riskier mortgages with low down payments. Borrowers are able to purchase a home with a down payment as small as 5%. This allows new home buyers to acquire a home and begin building equity sooner.

Growing Market Share in Canada

Recent news about the United States threatening to impose tariffs on Canadian goods has introduced significant uncertainty into Canada's economic landscape. These developments are poised to impact various sectors, notably the housing and mortgage markets. While the potential ramifications of these tariffs are not easy to predict, we attempt here to identify the issues we should all be considering. The Tariff Threat In early Feb, U.S. President Donald Trump announced significant tariffs on Canadian imports. He talks frequently about unfair trade and has also stated his objective was to address concerns over illegal immigration and drug trafficking into the United States. On February 1, 2025, he signed executive orders imposing a 25% tariff on all Canadian goods, excluding energy products, which were subjected to a 10% tariff. These tariffs were initially set to take effect on February 4, 2025. The US President Trump postponed the imposition of these tariffs for one month, until March 4, 2025. This postponement was intended to provide time for Canada to address U.S. concerns regarding border security and drug trafficking. On Feb 27, the US President confirmed that the tariffs on Canada and Mexico would be put in place as of March 4. This is not good news and hopefully Canadian diplomats can resolve this. Immediate Economic Implications Despite the delay to March 4, and some moves by Canada to address the issues, tensions have escalated. On February 10, 2025, President Trump announced additional tariffs - a 25% duty on all steel and aluminum imports, including those from Canada, set to commence on March 12, 2025. In response, Canada has threatened retaliatory tariffs on U.S. goods, making the prospect of an unexpected trade war between historically good neighbours a real possibility. The US has also said reciprocal tariffs will take effect in April. The situation remains fluid, with ongoing negotiations between the U.S. and Canada aiming to resolve trade disputes and address the underlying issues prompting the tariffs. These measures are expected to disrupt trade flows, elevate production costs, and potentially lead to a slowdown in economic growth. Bank of Canada Governor Tiff Macklem has cautioned that such trade conflicts could curb economic growth, hurt the Canadian dollar, and potentially lead to higher inflation. Impact on the Housing Market The imposition of tariffs on all goods and a retaliatory response from Canada would have several negative consequences for Canadian housing markets. Increased Construction Costs: Tariffs on imported materials, such as lumber and steel, would increase construction costs. Any increase in construction costs would be passed through to consumers, resulting in higher prices for both new homes and renovations. These elevated costs could exacerbate housing affordability issues and constrain the supply of new homes. Market Uncertainty: The prevailing economic ambiguity may deter potential buyers, leading to a deceleration in housing demand. Prospective homeowners might adopt a cautious stance, postponing purchases until the economic and interest rate outlook stabilizes. Job Losses: Higher costs could slow activity in housing development and renovation that could lead to job losses. This could place some current mortgage borrowers and homeowners under stress and take other potential new market entrants out of the market. Tariff Impact on Mortgages The impact that significant tariffs have on the mortgage market could be immediate: 1. Mortgage Rates There are diverging opinions currently about where mortgage rates may go if tariffs are imposed. There are two key channels through which we will see the interest rate impact. Bank of Canada Monetary Policy Adjustments - Most economists agree that a tariff war with the US will slow down the Canadian economy, perhaps sending us into a recession. The Bank of Canada may contemplate reducing interest rates to stimulate economic activity. Governor Macklem has indicated that monetary policy could support demand in the event of a trade war, suggesting that rate cuts might be more substantial than previously projected. However, many have cautioned that interest rate cuts may not have a meaningful impact on an economic slowdown resulting from higher costs due to tariffs. While the Bank of Canada may not be able to effectively offset the negative impact, many analysts, including those at the Bank of Montreal, think they might cut rates by as much at 1.50% this year if the US imposes the full 25%, across-the-board tariffs. This would significantly reduce variable mortgage rates, which would be beneficial for mortgage borrowers. Bond Yield Fluctuations - Escalating trade tensions have already led to a decline in Canadian bond yields, with the 5-year bond yield reaching its lowest point since June 2022. Bond yields often decline in advance of economic weakness. A downturn in bond yields is often followed by a decline in fixed mortgage rates, potentially offering relief to borrowers. 2. Reduced Market Activity The tariff talk creates tremendous uncertainty. The old saying is ‘uncertainty breeds contempt’ and we are seeing that in the reactions many are having to the tariff threat as well as in declining consumer confidence in survey results. We may witness a slowdown in housing and mortgage market activity with new buyers, movers, and investors exercising caution until the tariff issue is resolved. 3. Mortgage Defaults Economic weakness usually leads to worsening performance in mortgage portfolios. Job losses, loss of confidence and narrowing options will lead to an increase in mortgage defaults as borrowers struggle to meet obligations. We have already recently seen an uptick in consumer credit defaults and mortgage delinquencies have been increasing. Despite this concern, Canadian mortgage portfolios have performed well during prior downturns. The legal structure and culture in Canada promote good payment behavior and Canadians always do whatever it takes to keep their home.
