The purchase price is only the beginning. The costs of buying a home in Ontario can add thousands, and sometimes tens of thousands, of dollars to the amount you need before closing. For many first-time buyers and growing families in Mississauga and across the GTA, the surprise is not one large bill. It is several deadlines, deposits, taxes, insurance requirements, and closing adjustments arriving at once.
A clear budget protects you from last-minute pressure and lets you make an offer with confidence. The amounts below are general guidance. Your actual costs depend on the property, municipality, financing, contract terms, and whether you qualify for any available rebates or exemptions.
The costs of buying a home in Ontario start before closing
Down payment and deposit
Your down payment is the portion of the purchase price you pay from your own funds. For a home priced at $500,000 or less, the minimum down payment is generally 5%. For the portion of a purchase price between $500,000 and $999,999, the minimum is 5% on the first $500,000 and 10% on the remaining amount. Homes priced at $1 million or more generally require at least 20% down.
The deposit is different. It is money provided shortly after your offer is accepted and held in trust until closing. It is usually credited toward the purchase price and down payment, rather than added as a separate cost. Still, buyers need those funds available quickly. In competitive GTA transactions, a deposit is often expected within 24 hours of acceptance, subject to the wording of the agreement.
A larger down payment may reduce your borrowing costs, but it should not leave you without an emergency reserve. A home can need a furnace repair, appliance replacement, or unexpected maintenance shortly after you get the keys.
Mortgage insurance, appraisal, and lender charges
If your down payment is less than 20%, your lender will usually require mortgage default insurance. The premium is commonly added to your mortgage balance, although provincial sales tax on that premium is generally payable at closing. This is a cost buyers can overlook because it may not appear as a separate upfront premium.
Your lender may also require an appraisal to confirm the property’s value. Some lenders cover or waive this charge; others pass it on to the buyer. Depending on your financing and lender, there may also be an application, administration, or valuation fee. Ask for a written breakdown before you remove financing conditions.
If you are buying a newly built home, confirm early whether the advertised price includes HST and whether any builder incentives or HST rebates have been assigned to the builder. New-construction contracts can contain additional charges for development levies, utility connections, occupancy, and other adjustments.
Land transfer tax can change the equation
Ontario charges land transfer tax when ownership of most properties transfers. The tax is calculated on a sliding scale, so the amount rises with the purchase price. First-time homebuyers may qualify for an Ontario land transfer tax refund, subject to eligibility requirements.
Buyers purchasing in the City of Toronto should plan for an additional municipal land transfer tax. That means a Toronto purchase can carry two land transfer tax bills, although eligible first-time buyers may also have access to a municipal rebate.
For illustration, the Ontario land transfer tax on a $750,000 property is $11,475 before any first-time homebuyer refund. A property in Toronto would also attract municipal land transfer tax. These amounts can materially affect affordability, so they should be estimated before you decide what price to offer.
Land transfer tax rules, brackets, and rebates can change. A real estate lawyer can review your circumstances and confirm whether you may qualify for a rebate, particularly where title will be held by more than one person or one buyer has owned a home before.
Legal fees and closing disbursements
A real estate lawyer does much more than witness signatures on closing day. Your lawyer reviews the agreement of purchase and sale, searches title, checks for registered claims or restrictions, communicates with the lender, prepares closing documents, receives and transfers funds, and registers the transfer and mortgage.
Legal fees vary with the complexity of the transaction. In addition to the lawyer’s professional fee, buyers should expect disbursements and taxes. Disbursements may include title searches, registration fees, electronic filing charges, bank wire fees, and title insurance premiums.
Title insurance is commonly obtained in Ontario residential purchases. It can protect against certain title-related issues that may not appear in a standard search, such as fraud, survey defects, or some pre-existing work orders. It does not replace a home inspection, and it does not cover every problem with the property. Your lawyer can explain what it covers in your transaction.
Choosing counsel based only on the lowest advertised fee can create problems if the quote does not clearly identify disbursements, tax, title insurance, or extra charges for issues such as private mortgages, powers of attorney, or rushed closings. Ask for a transparent estimate and make sure you know what is included.
Inspections, insurance, and property-specific due diligence
A home inspection is not legally required, but it can be one of the most useful pre-closing expenses. An inspector may identify concerns with the roof, foundation, plumbing, electrical system, insulation, or drainage. The inspection cannot guarantee a trouble-free home, yet it can help you decide whether to proceed, renegotiate, or budget for repairs.
The right approach depends on the property and the market. Waiving an inspection condition can make an offer more attractive, but it transfers more risk to you. Older homes, rural properties, homes with additions, and properties sold as part of an estate may deserve especially careful review.
Your mortgage lender will typically require proof of home insurance before closing. Premiums vary based on location, rebuilding cost, claims history, heating type, and coverage. Condominium buyers should also review the status certificate and understand the corporation’s insurance, reserve fund, financial position, and any planned special assessments.
For a condo, monthly common expenses are not a closing cost, but they are part of the real cost of ownership. For a freehold home, set aside funds for maintenance, utilities, property taxes, and seasonal work that may have been handled by the previous owner.
Closing adjustments and funds due on possession
On closing, the seller may receive a credit for expenses they have prepaid beyond the closing date. Common adjustments include property taxes, fuel oil, rental equipment charges, and condominium fees. If the seller prepaid property taxes for a period after you take possession, you reimburse the seller for your portion through the statement of adjustments.
These adjustments are not necessarily unexpected charges. They are a fair allocation of costs between buyer and seller. However, they can increase the final amount your lawyer asks you to bring in certified funds or arrange by wire before closing.
Your statement of adjustments and reporting letter should show the purchase price, deposit credit, mortgage proceeds, land transfer tax, legal fees, disbursements, adjustments, and the final balance due. Review these documents carefully before closing. If something is unclear, ask. A purchase is too significant to sign or transfer funds without understanding the numbers.
Build a budget with room for real life
A practical closing budget includes more than mandatory transaction charges. Plan for moving expenses, utility connections, locksmith costs, window coverings, basic furniture, and immediate repairs. Even a well-maintained home often needs small changes to make it safe, comfortable, and functional for your family.
As a planning rule, many buyers aim to keep additional funds beyond the down payment for closing costs and an emergency cushion. The right amount depends on the purchase price, your lender’s requirements, the age and condition of the home, and your financial obligations after closing. A buyer with stable savings and a newer condo may plan differently than a family purchasing an older detached home with a septic system or pool.
Before making an offer, have your financing reviewed, request estimates for legal and insurance costs, and understand the tax consequences of the municipality where you are buying. A carefully reviewed agreement can also address important timing, condition, and deposit issues before they become urgent.
Buying a home should feel like a step toward security, not a scramble to find funds at the finish line. With clear advice and a realistic budget, you can approach closing prepared to protect both your new home and your financial future.
