Documents You'll Need for a Mortgage Application in Ontario

The single biggest thing that speeds up a mortgage application isn't your credit score or your rate shopping — it's having the right documents ready before you start.

Every lender needs to verify the same basic things: who you are, what you earn, where your down payment is coming from, and what you already owe. Here's what that looks like in practice for buyers across London, St. Thomas, Ingersoll, and Southwestern Ontario.

Identification

• A government-issued photo ID (driver's licence or passport)
• Your Social Insurance Number (SIN)

Proof of income

This varies depending on how you're employed:

If you're an employee

• Recent pay stubs (usually the last two)
• A letter of employment confirming your position, income, and start date
• Your most recent Notice of Assessment (NOA) from the CRA
• T4 slips for the past two years

If you're self-employed

• Two years of personal tax returns (T1 Generals) and Notice of Assessment
• Financial statements or business registration documents
• In some cases, bank statements showing business cash flow

If you're a newcomer to Canada

• A valid work permit, PR card, or study permit, depending on your status
• Proof of income from your current employer
• Alternative credit documentation if you don't yet have an established Canadian credit history — utility bills, rent payment history, or international credit references can all help build a picture for the lender

Proof of down payment

Lenders want to see where your down payment is coming from and that it's been in your account long enough (usually 90 days) to rule out undisclosed borrowing. This typically means:

• Recent bank or investment account statements
• If part of your down payment is a gift from a family member, a signed gift letter confirming it doesn't need to be repaid

Debts and liabilities

• Statements for any car loans, lines of credit, or other mortgages
• Credit card balances and minimum payments
• Details on any student loans or other financial obligations

Property information (if you have one in mind)

• The purchase agreement or MLS listing
• Property tax and condo fee information, if applicable

Frequently asked questions

Do I need all of these documents before I apply?

Not necessarily all at once. The conversation step helps identify exactly which documents apply to your situation, so you're not gathering things you don't need.

What if I'm missing something?

It's common. We'll work with you to find alternatives or explain to the lender why something is structured the way it is.

How far back do lenders look at my finances?

Typically the last two years for income and tax documents, and the last 90 days for down payment funds.
