The Mortgage Accountant Letter: Facts, Boundaries and Better Requests

Mortgage professionals often use the phrase 'accountant letter' as shorthand for several different needs: confirming the client has operated a business for a stated period, confirming ownership, identifying the accountant's relationship to the client, explaining a material financial-statement item, or confirming that specified tax filings were prepared. These are not the same engagement.

The broker should therefore obtain the lender's exact requirement and convert it into a narrow factual request. That lets the accountant decide whether the fact is within their knowledge and existing engagement, and whether a new engagement or disclaimer is appropriate.

A statement such as 'our firm prepared the corporation's 2025 financial statements' is fundamentally different from 'the owner can safely withdraw $150,000 annually without affecting the company.' The first describes completed work. The second may involve future operations, liquidity, tax, legal rights and business judgment.

Similarly, 'the shareholder owns 100% of the common shares based on the records provided to us' is different from guaranteeing that the borrower has unrestricted access to every dollar of corporate cash. Mortgage underwriting should not outsource the lender's credit judgment to the accountant through vague wording.

A strong request identifies the client, corporation, fact, period and lender reason. For example: 'The lender has asked us to confirm the date the corporation began operating and the borrower's current ownership percentage. Please confirm whether you can provide those facts from your records.' That is easier to assess than 'Please send a letter confirming the business is stable and profitable.'

If the lender needs an explanation of a one-time expense or related-party transaction, identify the exact line item and fiscal year. If the lender needs evidence of business tenure, ask whether an existing document can satisfy the requirement before commissioning a special letter.

CPA Ontario's Code emphasizes integrity, due care, professional competence and confidentiality. A mortgage deadline should not pressure an accountant to associate with a false or misleading statement or disclose client information without proper authority.

Mortgage professionals can reduce that pressure by sending requests early, stating exactly what the lender needs and avoiding lender-created wording that asks the accountant to certify matters outside the accounting engagement.

Published insurer guidance lists several ways to establish business tenure and self-employed income, including tax returns, NOAs, business licences, articles, GST/HST evidence, public registries and financial statements. A bespoke accountant letter should not be the reflex if an objective source already answers the question.

The mortgage professional should first ask: what fact is missing, what evidence does the lender accept, and is the accountant actually the best source? This keeps professional work proportional and reduces unnecessary liability for everyone involved.
