For real estate professionals in Ontario, a deep understanding of real estate financing is not just an asset—it is a regulatory requirement under the Trust in Real Estate Services Act, 2002 (TRESA). Whether you are representing a first-time homebuyer or an experienced investor, your ability to accurately calculate the Loan-to-Value (LTV) ratio and mandatory down payments is critical. This guide provides a comprehensive overview of loan-to-value and down payment calculations, specifically tailored for candidates preparing for the Ontario Real Estate Broker Exam.
Understanding the Loan-to-Value (LTV) Ratio
The Loan-to-Value (LTV) ratio is a financial metric used by lenders to assess the risk of a mortgage loan. It represents the ratio of the mortgage amount to the appraised value (or purchase price) of the property, expressed as a percentage. In Canada, lending institutions governed by the Office of the Superintendent of Financial Institutions (OSFI) rely heavily on LTV to determine mortgage eligibility, interest rates, and the necessity of default insurance.
The LTV Formula
The formula for calculating the LTV ratio is straightforward, but it contains a common trap for exam candidates:
LTV Ratio = (Mortgage Amount ÷ Lending Value) × 100
Exam Tip: The "Lending Value" is always the lesser of the property's purchase price or its appraised value. If a buyer purchases a home for $800,000 but the bank's appraiser values it at $750,000, the lender will base the LTV (and the required down payment) on the $750,000 figure. The buyer must make up the $50,000 difference out of pocket, in addition to their standard down payment.
Federal Down Payment Requirements Applicable in Ontario
In Ontario, minimum down payment requirements are dictated by federal regulations. These rules are tiered based on the purchase price of the property. As a broker, you must be able to calculate these tiers instantly.
- Properties up to $500,000: A minimum down payment of 5% of the purchase price is required.
- Properties between $500,000 and $999,999: A minimum down payment of 5% is required on the first $500,000, plus 10% on the portion of the price above $500,000.
- Properties $1,000,000 and over: A strict minimum down payment of 20% of the total purchase price is required. Mortgage default insurance is not available for properties in this price range.

Conventional vs. High-Ratio Mortgages
Understanding LTV leads directly to the distinction between mortgage classifications:
- Conventional Mortgage: An LTV of 80% or less (meaning the buyer has provided a down payment of at least 20%). These mortgages do not legally require default insurance.
- High-Ratio Mortgage: An LTV of greater than 80% (meaning the down payment is less than 20%). Under the Bank Act, these mortgages must be insured by a recognized provider, such as the Canada Mortgage and Housing Corporation (CMHC), Sagen, or Canada Guaranty.

Practical Calculation Scenarios for the Broker Exam
The Ontario Broker Exam will test your ability to apply these rules to realistic scenarios. Let's walk through two essential examples.
Scenario 1: The Tiered Down Payment ($750,000 Purchase)
Your client wants to purchase a single-family home in Ottawa for $750,000. What is the absolute minimum down payment required, and what is the base LTV?
- Calculate the first tier: 5% of the first $500,000 = $25,000.
- Calculate the second tier: 10% of the remaining $250,000 ($750,000 - $500,000) = $25,000.
- Total Minimum Down Payment: $25,000 + $25,000 = $50,000.
- Calculate Mortgage Amount: $750,000 - $50,000 = $700,000.
- Calculate LTV: ($700,000 ÷ $750,000) × 100 = 93.33%.
Because the LTV is above 80%, this is a high-ratio mortgage and will require CMHC insurance. Note: The insurance premium is typically added to the mortgage principal, which technically pushes the final LTV higher, but the initial qualification LTV is 93.33%.
Scenario 2: The Appraisal Shortfall ($1,100,000 Purchase)
Your client wins a bidding war in Toronto, agreeing to pay $1,100,000 for a property. Because the price is over $1 million, a 20% down payment is required. However, the lender's appraiser values the home at only $1,000,000.
- Determine the Lending Value: The lesser of the purchase price ($1,100,000) or appraised value ($1,000,000). The lending value is $1,000,000.
- Calculate the Maximum Mortgage: The lender will finance up to 80% of the lending value. 80% of $1,000,000 = $800,000.
- Calculate the Required Cash to Close: The buyer must cover the gap between the purchase price and the mortgage amount. $1,100,000 - $800,000 = $300,000.
Instead of the expected $220,000 (20% of $1.1M), the buyer must bring $300,000 to closing. As a broker, anticipating this risk and advising your client on appraisal shortfalls is a fundamental fiduciary duty.
Regulatory Context: TRESA and Broker Competence
Under the Trust in Real Estate Services Act, 2002 (TRESA), brokers are held to a high standard of care. Providing inaccurate financial advice regarding down payments or LTV ratios can lead to a client breaching a contract, resulting in severe legal and financial consequences, as well as RECO (Real Estate Council of Ontario) disciplinary action.
Brokers must ensure they are advising clients holistically. For instance, an investor buying a multi-residential property might need you to explain property management basics, while a buyer of a heritage home must be made aware of lead paint disclosure requirements. However, neither transaction can successfully close without a solid, mathematical grasp of the financing fundamentals discussed here.
Conclusion
Mastering LTV and down payment calculations is a non-negotiable skill for passing the Ontario Broker Exam and succeeding in real estate practice. Remember to always use the lesser of the purchase price or appraised value, memorize the federal tiered down payment structure, and understand the 80% threshold for high-ratio mortgages.

Frequently Asked Questions (FAQs)
What happens if a property is purchased for over $1 million in Ontario?
If a property's purchase price is $1,000,000 or more, federal rules prohibit mortgage default insurance (like CMHC). Consequently, the buyer must provide a minimum down payment of 20% of the purchase price, resulting in a maximum LTV of 80%.
Does the CMHC insurance premium affect the LTV ratio?
For qualification purposes, the base LTV is calculated before the insurance premium is added. However, because the premium is usually capitalized (added to the total mortgage amount), the final working LTV of the loan will be slightly higher than the initial calculation.
Can a buyer use borrowed funds for their down payment in Ontario?
Yes, under certain lending programs, a buyer can use borrowed funds (like a line of credit) for a down payment. This is often referred to as a "flex down" mortgage. However, the lender will factor the debt servicing costs of those borrowed funds into the buyer's Gross Debt Service (GDS) and Total Debt Service (TDS) ratios, making qualification much stricter.
What is the difference between purchase price and lending value?
The purchase price is the amount the buyer and seller agree upon in the Agreement of Purchase and Sale. The lending value is determined by the lender, almost always based on an independent appraisal. Lenders will calculate the LTV based on whichever of these two numbers is lower to protect themselves against market overvaluation.
Are down payment rules different for investment properties?
Yes. If the property is not going to be owner-occupied (i.e., it is strictly an investment/rental property), mortgage default insurance is typically not available for 1-4 unit properties. Therefore, a conventional mortgage with a minimum 20% down payment is required, regardless of whether the purchase price is under $1 million.
