Buying your first home in Ontario is exciting, but there are a lot of moving parts. Down payment rules, closing costs, mortgage stress test requirements, lender conditions, insurance premiums, tax credits, rebates, and offer timelines can all affect your plan.
A strong first-time buyer mortgage plan helps you understand what you may qualify for, what you can comfortably afford, how much cash you may need at closing, and what conditions could affect approval before you start making offers.
Review Your First Purchase Plan Use Mortgage Calculators
A first-time buyer in Ontario should start with a mortgage pre-approval review before serious house hunting. This helps confirm your realistic price range, payment comfort, down payment source, closing cost needs, lender options, and any conditions that could affect approval. The best mortgage is not always the largest mortgage available. It is the mortgage that fits your income, debts, credit, savings, timing, and future plans.
This page is for Ontario buyers who are preparing for their first home purchase and want a plain-English mortgage plan before they start shopping seriously.
Before you start viewing homes, get a mortgage pre-approval review. This is more than asking for a rate. A useful review looks at your full financial picture and helps identify what a lender may actually approve.
A first-time buyer mortgage review should usually look at:
This matters because the amount you can technically qualify for may not be the same as the amount you will feel comfortable carrying. A good mortgage plan should account for real life, not just a maximum approval number.
Your minimum down payment depends mainly on the purchase price. If your down payment is less than 20%, the mortgage is usually considered a high-ratio insured mortgage and mortgage default insurance will generally apply.
For example, on a $700,000 purchase, the minimum down payment would usually be 5% of the first $500,000 plus 10% of the remaining $200,000. That equals $25,000 plus $20,000, for a total minimum down payment of $45,000.
Some lenders may require a larger down payment depending on the file, property, income type, credit history, or overall risk. If you are self-employed, recently changed jobs, have credit challenges, or are using gifted funds, review the details before you make an offer.
Your down payment is not the only cash you need. First-time buyers in Ontario should also plan for closing costs. These costs vary by property, location, lender, lawyer, and transaction details.
Common closing costs may include:
A common mistake is shopping based only on the down payment. Before making an offer, confirm approximately how much cash you need for both the down payment and closing costs.
Several programs and benefits may help eligible first-time buyers. Rules can change, and each program uses its own definitions, timelines, property rules, and eligibility requirements. Always verify the details before relying on a program for your closing plan.
Do not assume you qualify for every first-time buyer program just because this is your first purchase. Some programs use different definitions, relationship rules, occupancy rules, property rules, timelines, or withdrawal requirements.
First-time buyers often focus on rate first. Rate matters, but the mortgage structure matters too. The wrong structure can create problems later if you need to sell, refinance, renew early, access equity, or change plans.
A fixed-rate mortgage gives you a set interest rate for the term. This can make budgeting easier because your payment is more predictable. Fixed rates may suit buyers who value stability, but you should understand the penalty rules if you break the mortgage early.
A variable-rate mortgage can change when the lender's prime rate changes. This may appeal to buyers who are comfortable with rate movement and potential payment or interest-cost changes. It is important to understand how the lender handles payment changes, trigger rates, and conversion options.
A closed mortgage usually has a lower rate but less flexibility to repay or break the mortgage early. An open mortgage usually offers more flexibility but often comes with a higher rate. Most first-time buyers choose closed terms, but the right answer depends on your plans.
If you have less than 20% down, mortgage default insurance will usually apply. If you have 20% or more down, the mortgage is usually conventional. A conventional mortgage avoids the default insurance premium, but it requires more money upfront.
You can learn more about broader mortgage structures on the mortgage types page.
Affordability is not just about income. Lenders also look at debt payments, property taxes, heating costs, condo fees if applicable, credit history, down payment, and the mortgage stress test.
It is helpful to separate three different numbers:
For many first-time buyers, the best mortgage plan is not about stretching to the absolute maximum. It is about getting into the market with a payment and structure that still leaves breathing room.
You can use the mortgage calculators as a starting point, but a calculator should not replace a full pre-approval review.
The exact process can vary, but most first-time buyer mortgage files follow a similar path.
For a broader purchase overview, review the buying property page.
Some first-time buyer files are straightforward. Others need more strategy. That does not automatically mean you cannot buy, but it does mean the file should be reviewed carefully.
You may need extra planning if:
If income is the main issue, review mortgage options with income issues. If credit is the concern, review mortgage options with credit issues. If you are considering a new build, review new construction financing.
The documents required depend on the lender and your situation. Common documents may include:
Self-employed buyers may need additional documents such as business financial statements, T1 Generals, business bank statements, articles of incorporation, or accountant-prepared documents, depending on the lender and income approach.
Many first-time buyer problems can be avoided with early planning. The most common issues are often simple timing, documentation, or budgeting mistakes.
The home buying FAQ may also help if you are still learning the purchase process.
First-time buyers often have questions that go beyond rate. A mortgage broker can help compare lender options, explain the process, review documents, identify risks, and help you understand the tradeoffs before you commit.
This can be especially helpful when your file is not perfectly simple. Different lenders may look at income, debt, credit, property type, and down payment sources differently.
The goal is not just to get a mortgage. The goal is to understand your options clearly enough to make a confident decision.
If you are thinking about buying your first home in Ontario, it may help to review your numbers before you start making offers. A clear plan can help you understand your budget, down payment, closing costs, and lender options.
Start With a First-Time Buyer Review Review the Buying Process
Possibly, depending on the purchase price, property, income, credit, debts, and lender approval. For homes at or below $500,000, the minimum down payment is generally 5%. For higher purchase prices below $1,500,000, the minimum down payment is calculated in tiers.
No, not always. Many first-time buyers purchase with less than 20% down using an insured mortgage. If your down payment is less than 20%, mortgage default insurance will usually apply.
Often yes, if the gift meets lender requirements. Lenders usually want a signed gift letter and proof that the funds have been received. The gift generally needs to come from an acceptable source, depending on lender policy.
Eligible buyers may be able to use both for the same qualifying home, provided they meet the requirements for each program. It is important to confirm the rules before withdrawing funds.
You can speak with a Realtor early, but it is usually best to understand your mortgage range before serious house hunting. A pre-approval review helps you shop with clearer numbers and reduces the risk of looking at homes outside your comfort zone.
Yes, self-employed buyers may qualify, but the documentation and lender options can be different. It is best to review income early so there is time to determine which lenders may consider the file and what documents they may need.
