Buying a house in Ontario involves paperwork at multiple stages — mortgage pre-approval, the offer, and closing day each require different documents. Missing a single required document at the wrong moment can delay your pre-approval, slow down the conditional period, or create problems at closing. Knowing what to prepare ahead of time, and gathering these documents before you need them, makes the process significantly smoother. This guide covers every document required to buy a house in Ontario, organized by stage.

Getting your documents ready is one of the first practical steps in buying a home in the GTA. If you haven't started the pre-approval process yet, see how to get mortgage pre-approval in Canada.

Documents for Mortgage Pre-Approval

A mortgage pre-approval requires your lender or mortgage broker to verify your identity, income, employment, assets, and existing debts. These are the documents you'll need to submit:

Identity

  • Two pieces of government-issued photo ID (passport, driver's licence, or permanent resident card)
  • Social Insurance Number (SIN) — required for the credit bureau pull

Employment and Income (Salaried Employees)

  • Most recent T4 slip(s) — typically the last 2 years
  • Most recent 2 pay stubs
  • Letter of employment on company letterhead confirming your position, salary, and employment start date
  • Last 2 years' T1 general tax returns (required by some lenders, especially for income verification when overtime or bonuses are part of your qualifying income)
  • Last 2 years' Notices of Assessment (NOA) from CRA — confirming no outstanding tax owing

Employment and Income (Self-Employed)

  • Last 2 years' T1 general tax returns with all schedules
  • Last 2 years' Notices of Assessment (NOA)
  • Last 2 years' business financial statements (T2125 schedule or corporate financials if incorporated)
  • Business registration documents (Certificate of Incorporation or Master Business Licence)
  • 6 months of business bank statements (some lenders require this)

Self-employed buyers face additional documentation requirements because lenders need to establish two years of stable income history. See buying a home while self-employed for a full breakdown of what to expect.

Down Payment and Assets

  • 90 days of bank statements for all accounts where your down payment is held
  • RRSP, TFSA, and investment account statements if funds will come from those accounts
  • Gift letter (if part of the down payment is a gift from a family member) — the letter must confirm the funds are a true gift with no repayment required
  • RRSP Home Buyers' Plan withdrawal confirmation (if using the HBP)
  • First Home Savings Account (FHSA) statements (if using FHSA funds)
  • Sale proceeds confirmation if down payment comes from selling a previous home

Debts and Liabilities

  • Most recent statements for all credit cards, car loans, student loans, lines of credit, and any other debts
  • Lease agreement (if you have monthly rent obligations that will affect your TDS ratio)

Lenders also pull your credit bureau report directly — you don't need to provide your credit score, but you should review your own credit report in advance to check for errors. Equifax Canada and TransUnion Canada each offer free annual credit reports.

Documents at the Offer Stage

Once you have an accepted offer, your agent will have handled the Agreement of Purchase and Sale (APS). During the conditional period, additional documents come into play:

  • Accepted APS: Your lawyer and lender both need a copy of the signed agreement to proceed with title work and formal mortgage approval
  • Home inspection report: Provided by your inspector — your lawyer and lender may want to review it if there are significant findings
  • Status certificate: For condos, this is a package of documents about the condo corporation — your lawyer must review it during the status certificate condition period
  • Property disclosure statement: If the seller provided one (not legally required in Ontario but common in some transactions)
  • Survey: If the seller provides one and the property is freehold — your lawyer will review it, though title insurance typically compensates for survey issues

Documents for Closing Day

By closing day, most of the heavy documentation work is done. What you need to bring or have ready:

  • Two pieces of photo ID: Your lawyer will verify your identity again at the signing appointment
  • Certified cheque or bank draft: For the balance owing at closing (your lawyer will confirm the exact amount from the statement of adjustments, typically a few days before closing)
  • Wire transfer confirmation: If you're transferring funds electronically — confirm the amount and recipient account with your lawyer well in advance
  • Home insurance certificate: Proof that your home insurance policy is active on the closing date — your lender requires this before advancing mortgage funds
  • Void cheque or banking information: For your lender to set up the mortgage payment pre-authorization

Your lawyer handles most of the closing documentation — the transfer of title, mortgage registration, and land transfer tax remittance — on your behalf. Your role on closing day is primarily to sign what your lawyer puts in front of you and provide the funds.

Documents to Request From the Seller

Through your agent and lawyer, you should request or confirm:

  • Utility bills (past 12 months) — to verify actual carrying costs and flag unusual consumption
  • Property tax bills — to confirm annual tax amount and verify the property tax adjustment at closing
  • Warranty documentation — for appliances, roof, HVAC, or other systems with existing warranties
  • Renovation permits — to verify that any completed work was properly permitted
  • Rental equipment agreements — for hot water heater, HVAC, or security system rentals that transfer to the new owner

Rental equipment agreements are something buyers frequently overlook. A rented hot water heater carries a monthly cost of $40–$80/month and a buyout cost of $800–$2,000 — worth knowing before closing. Your home inspection report should flag any rental equipment on the property.

FAQ

What income documents do I need for a mortgage in Canada?

Salaried employees need T4 slips from the last 2 years, 2 recent pay stubs, a letter of employment, and Notices of Assessment. Self-employed buyers need 2 years of T1 generals, NOAs, and business financial statements. All buyers need 90 days of bank statements showing their down payment funds.

Do I need a lawyer to buy a house in Ontario?

Yes. Every Ontario home purchase requires a real estate lawyer. Your lawyer conducts the title search, prepares closing documents, receives mortgage funds from your lender, remits land transfer tax, and registers the transfer of ownership. You cannot close a property purchase in Ontario without a lawyer.

What is a gift letter for a mortgage down payment?

A gift letter is a signed document from the family member who is gifting you money for your down payment. It must confirm the donor's name and relationship to you, the amount being gifted, the date, and a statement that the money is a true gift with no repayment required. Most lenders have their own gift letter template. Gifted funds from non-family members are treated differently and may not be accepted by all lenders.

Do I need my Notice of Assessment to buy a home?

Yes. Lenders require Notices of Assessment from the last 1–2 years to verify your reported income matches what CRA has on file, and to confirm you have no outstanding tax debt. If you filed late or have an installment balance owing to CRA, this needs to be disclosed and resolved before most lenders will proceed.

What documents does my lawyer need when I buy a home?

Your lawyer needs a copy of the signed Agreement of Purchase and Sale, your photo ID, and your mortgage commitment letter (which your lender sends directly or through your broker). For condos, they also need the status certificate package. On closing day, they coordinate receipt of mortgage funds from the lender and balance funds from you.
