Income Verification

Income verification is the documentation a lender requires to qualify a borrower for a mortgage, typically including recent pay stubs, T4 slips, Notices of Assessment from the Canada Revenue Agency, and an employment letter. Self-employed and commission-income borrowers usually provide two years of T1 General returns plus business financials. Lenders require originals or e-signed copies and commonly confirm employment directly with the employer. Income-verification standards for federally regulated lenders are set under OSFI Guideline B-20 (as of 2026-07-27 — verify current).

OSFI Guideline B-20 sets residential mortgage underwriting practices and procedures, including income-verification requirements, for federally regulated financial institutions (as of 2026-07-27 — verify current). The guideline requires lenders to verify a borrower's income using reliable documentation before approving a mortgage. Verify the current version and requirements with a licensed mortgage professional or the Office of the Superintendent of Financial Institutions (OSFI) at www.osfi-bsif.gc.ca before acting.

Salaried employees typically provide recent pay stubs (usually covering a 30-day period or most recent pay period), a letter of employment confirming position and salary, and copies of the most recent T4 slips and Notices of Assessment from the Canada Revenue Agency. Lenders may also contact the employer directly to confirm employment and income details. Verify the specific documentation requirements with your lender or licensed mortgage broker, as requirements can vary by lender and loan type (as of 2026-07-27 — verify current).

Self-employed borrowers usually must provide two years of T1 General tax returns (personal) and Notices of Assessment from the Canada Revenue Agency, plus business financials such as financial statements or T2 corporate returns if operating through a corporation (as of 2026-07-27 — verify current). Lenders may also require interim financial statements, a letter from an accountant, or proof of business registration. Because self-employed income verification is more complex and lender-specific, verify the exact documentation required with a licensed mortgage professional before applying.

Rental income can often be used to qualify for a mortgage, but lenders typically require documentation such as executed lease agreements, proof of rental deposits, and a history of rental income reported on the borrower's T1 General tax returns (usually two years) to verify consistency (as of 2026-07-27 — verify current). Some lenders apply a percentage discount to the gross rental income to account for vacancies and expenses. Verify the specific treatment and documentation requirements with a licensed mortgage broker or lender, as policies vary.

Most lenders accept electronically signed (e-signed) or scanned copies of income-verification documents, provided they can verify authenticity and the documents are obtained directly from the source (e.g., CRA My Account portal for Notices of Assessment) (as of 2026-07-27 — verify current). Lenders commonly require originals or certified copies for certain documents and will verify employment and income directly with employers or through third-party verification services. Confirm the lender's specific requirements for document format and authentication with your mortgage broker or lender before submitting.

British Columbia does not have a provincial statute that prescribes the specific income-verification documents a lender must collect; these standards are set primarily by federal regulators (OSFI Guideline B-20 for federally regulated lenders) and by individual lender policies (as of 2026-07-27 — verify current). The Real Estate Services Act (RESA), SBC 2004, c. 42, and BCFSA Rules govern the conduct of mortgage brokers and submortgage brokers in BC, but do not prescribe lender underwriting documentation. Verify current income-verification requirements with a licensed mortgage professional or your lender.

The CRA Notice of Assessment is a key income-verification document that confirms the income a borrower reported on their tax return and that the return has been assessed by the Canada Revenue Agency (as of 2026-07-27 — verify current). Lenders use it to verify consistency between reported income and the income declared on mortgage applications, particularly for self-employed borrowers and those with complex income sources. Borrowers can obtain their Notice of Assessment through the CRA My Account portal or by contacting CRA directly.

Commission-income borrowers are typically required to provide two years of T1 General tax returns, Notices of Assessment from the Canada Revenue Agency, and recent pay stubs showing base salary and commission income to demonstrate stability and average earnings (as of 2026-07-27 — verify current). Lenders often average the commission income over the documented period and may apply conservative calculations to account for variability. Verify the specific documentation and calculation method with a licensed mortgage broker or lender, as requirements vary.

A BC real estate licensee may provide general information about typical income-verification documents and timelines, but must not provide mortgage advice, prepare financial documents, or act as a mortgage broker unless separately licensed under the Real Estate Services Act (RESA), SBC 2004, c. 42, and registered with the British Columbia Financial Services Authority (BCFSA) (as of 2026-07-27 — verify current). Buyers should work directly with a licensed mortgage broker or their lender for income-verification requirements. Verify the scope of permissible assistance with BCFSA or a BC lawyer if uncertain.
