When both sides sign an accepted offer in Ontario, you have a binding contract. But the deal is not done. The buyer still has to pay a deposit, clear any conditions, arrange the money and wait for closing day. The seller has a to-do list too.
The signed contract is called the Agreement of Purchase and Sale, or APS. Everything that follows comes from it, including the closing date. The buyer and seller choose that date in the offer. A longer close gives more time to sell another home or plan a move. A shorter one suits a buyer who is ready now.
This guide walks buyers and sellers through each step, in order, for homes in Mississauga, Oakville, Burlington and Milton. It also shows where deals most often go wrong.
Step 1: The Offer Becomes a Contract
An offer becomes a contract when the seller accepts it and both sides sign. If the seller changes anything, that is a counter-offer. The buyer can accept it, refuse it or counter again. Only the final version both sides sign counts.
Right after signing:
- Save a full copy of the signed APS, with every page and schedule.
- Write down every date and deadline in one place.
- Tell your lawyer and your mortgage lender that you have a deal.
- Avoid big money moves, such as a new car loan. They can affect your mortgage approval.
Step 2: The Deposit
The buyer pays a deposit to show good faith. The APS says when it is due. It is often due on acceptance or within 24 hours, so read your contract.
- It is not extra money. It counts toward the price on closing day.
- It is held in a trust account, usually by the seller’s brokerage, not by the seller.
- It is usually paid by bank draft, certified cheque or wire transfer.
- If it is late, the seller may be able to end the deal.
- If a deal falls apart because a condition was not met, both sides sign a mutual release before the deposit is returned.
Plan ahead. Keep the deposit in an account you can reach quickly, not in investments that take days to sell. Banks can also limit large transfers, so ask about limits before you make an offer.
Step 3: Conditions
A condition means the deal only goes ahead if something happens by a set date. The most common ones are:
- Financing. The buyer’s mortgage must be approved.
- Home inspection. The inspector must find nothing the buyer cannot accept.
- Status certificate review. For condos, the buyer’s lawyer reviews the building’s documents.
- Sale of the buyer’s home. Less common, and many sellers dislike it.
- Lawyer review. The buyer’s lawyer checks the contract.
Conditions usually last a few business days. Before time runs out, the buyer either removes the condition in writing, usually with a waiver or a notice of fulfillment, or ends the deal under the contract’s terms. Talk to your agent and lawyer before you sign anything. Our guide to offer conditions in Ontario goes deeper.
For condo buyers
The status certificate shows the building’s finances, rules, reserve fund and any legal disputes. A building with a weak reserve fund may bill owners extra later. Read the condo status certificate, explained before your lawyer’s review.
For sellers
While conditions are open, your home is “conditional.” Some sellers keep showing it or take back-up offers, if the contract allows. Ask your agent what is allowed, and be ready to send any papers the buyer asks for.
Step 4: Mortgage Approval and the Appraisal
The buyer sends the signed contract to the lender. The lender checks income, savings and credit, and often orders an appraisal, an expert opinion of the home’s value. If the appraisal comes in below the price, the lender may lend less. The buyer must then cover the gap.
- Get a pre-approval before you shop.
- Keep a cash cushion in case of a gap.
- Answer your lender quickly when it asks for papers.
- Keep your job and credit steady until you have the keys.

Step 5: The Home Inspection
An inspector checks what can be seen and tested: roof, structure, heating, plumbing, electrical and more. They cannot see inside walls. If the report finds a problem, the buyer can accept the home as is, ask for a repair, ask for a lower price or credit, or end the deal if the condition allows. Any change must be in writing and signed by both sides. See our home inspection guide.
Sellers: a fair answer to an inspection request often keeps a deal alive. A flat refusal can lose it.
Step 6: The Lawyers Do the Legal Work
In Ontario, the buyer and the seller each have a real estate lawyer. Pick yours early and send them the signed contract right away.
For the buyer, the lawyer:
- Searches the title, to confirm the seller owns the home and can sell it.
- Checks for liens, unpaid taxes, city work orders and other claims.
- Sends the seller’s lawyer any problems to fix by the requisition date, the deadline set in the APS.
- Arranges title insurance, which most lenders require.
- Prepares the transfer and mortgage papers.
A lien is a legal claim against a home for money owed. For example, an unpaid contractor can register one. The seller must clear it before closing.
For the seller, the lawyer pays off the old mortgage, prepares the transfer, clears any title issues and makes sure the sale money arrives, minus what is owed.
Step 7: The Final Funds
The seller’s lawyer prepares a Statement of Adjustments. It splits costs the seller has already paid, such as property tax or a full fuel tank, so each side pays only for its own days. The buyer’s lawyer checks it, then tells you the exact amount to bring. That amount covers the rest of the down payment, the land transfer tax, legal fees and the adjustments, minus your deposit.
Send the funds by bank draft or wire transfer, a few days early if your lawyer asks. Check your bank’s transfer limits ahead of time. Our closing costs guide lists every fee, and the land transfer tax calculator works out the biggest one. Mississauga, Oakville, Burlington and Milton do not charge a city land transfer tax, so you pay only the Ontario tax.

Step 8: Insurance, Utilities and Moving
Your lender will not release the mortgage without proof of home insurance. Set it up well before closing and send the details to your lawyer.
- Set up electricity, gas, water and internet for move-in day. Each city has its own utility companies, so start a couple of weeks early.
- Change your address with banks, work and the government.
- Book movers early, since popular dates fill up.
- For condos, book the elevator and ask about move-in rules or deposits.
Sellers should cancel utilities and insurance as of the closing date, not before. Leave the home clean and empty unless the contract says otherwise, and hand over keys, fobs, remotes and manuals.
Step 9: The Final Walkthrough
Most contracts let the buyer visit once or twice before closing. The last visit checks that nothing has changed, repairs are done and included items are still there. Test the appliances, run the taps and look for damage from the move. Bring our final walkthrough checklist. If you find a problem, tell your agent and lawyer right away. Your lawyer may be able to hold back money until it is fixed.
Step 10: Closing Day
Closing day is when ownership changes. Buyers sign their papers with their lawyer ahead of time. On the day, the lender sends the mortgage money to the buyer’s lawyer, who adds the buyer’s funds and sends the total to the seller’s lawyer. The sale is then registered electronically, and the keys are released.
Keys often come later in the day, after the money is confirmed. Delays are common and usually come from banks or registration timing, so plan your move with some slack.
How Closing Differs by Property Type
Detached homes need the most careful inspection: roof, foundation, heating and plumbing are all yours. Condo apartments rely more on the status certificate, because the building’s finances affect your costs. Browse Mississauga condos for sale to see the range. Townhouses can be freehold or condo. With a freehold, you own the land and look after the roof and yard yourself. With a condo townhouse, a monthly fee covers shared upkeep. Our guide to freehold vs. condo townhouses explains the difference.
Local Tips for Milton, Oakville and Burlington
Much of Milton is newer housing, and some homes still have new-home warranty coverage. Ask your lawyer to confirm what coverage is left and that it passes to you. Older areas such as Bronte in Oakville have mature trees, whose roots can affect sewer lines. A sewer scope during the inspection is worth asking about.
Where Deals Go Wrong
- Missed deadlines. A late deposit or a late waiver can end a deal.
- Financing problems. A job change, new debt or a low appraisal can derail a mortgage.
- Inspection surprises. Big issues can lead to new talks, or to the deal falling apart.
- Title issues. Liens, unpaid taxes or errors can slow things down.
- The home changes. Damage between acceptance and closing must be dealt with right away.
- Not closing on time. A buyer who cannot close may lose the deposit and be sued for the seller’s losses.
The fix is simple: know your dates, answer quickly, and keep everything in writing.
How the Market Shapes This Stage
When buyers have lots of choice, they can ask for a longer close, more conditions or repairs. When homes are scarce, sellers bend less, and buyers need their paperwork ready early. Check the live market reports to see which way your area leans right now.

Frequently asked questions
How long does closing take in Ontario?
The buyer and seller choose the closing date in the offer. Most closings are set somewhere between 30 and 90 days after acceptance, but shorter and longer closes happen.
What happens right after my offer is accepted?
You have a binding contract. The buyer pays the deposit when the contract says, both sides track the condition dates, and each side brings in their lawyer.
Is the deposit extra money on top of the price?
No. It counts toward the purchase price and is held in trust until closing.
Can I back out after the offer is accepted?
Only if your contract allows it, for example if a condition is not met in time. Backing out otherwise can cost you your deposit and more. Ask your lawyer first.
What is a Statement of Adjustments?
A document from the seller’s lawyer that splits costs the seller already paid, such as property tax, so each side pays only for its own days. Your lawyer uses it to work out the final amount you bring.
Do I need title insurance?
Most lenders require it. It protects you and the lender against title problems such as old debts on the home or title fraud.
What happens on closing day?
The lender sends the mortgage money to your lawyer, your lawyer sends the full amount to the seller’s lawyer, the sale is registered, and the keys are released.
What happens if I cannot close on time?
You would be in breach of the contract. The seller may keep your deposit and sue for their losses. Stay in close touch with your lender and lawyer so it never comes to that.
