Short answer
Because the lender and mortgage professionals must understand whether the money is genuine business revenue, borrowed money, a transfer between owned accounts or funds from another person. A clean paper trail protects both the approval and the client.
The client concern
A self-employed buyer moves money among several personal and business accounts before closing. Nothing improper happened, but the statements now look confusing and the lender pauses the file while the financing condition or closing date approaches.
What the official guidance establishes
FINTRAC’s framework requires reporting entities to know clients, verify identity in prescribed circumstances and meet recordkeeping and reporting obligations. Separately, each lender sets source-of-funds and down-payment documentation requirements.
What it does not guarantee
FINTRAC does not prescribe a universal “90-day mortgage rule,” and a large deposit is not automatically suspicious. Ninety days is a common lender review window, while some files require more or less. The lender—not FINTRAC—decides whether the submitted evidence satisfies its mortgage policy.
A practical Ontario example
Illustration only: A buyer transfers $60,000 from a corporation to a personal account, receives a $25,000 family gift and moves savings from another bank. Without statements showing each origin and transfer, the final account looks like unexplained new money.
Practical options to explore
Avoid unnecessary account movement before closing. Keep every page of statements, gift documentation, sale receipts and transfer confirmations. Explain deposits before the lender asks. If business funds are involved, coordinate the accountant, lawyer and broker early rather than trying to reconstruct the trail days before closing.
Questions worth asking
- Which income method is this lender actually using?
- Is the number based on tax income, business cash flow or property equity?
- Which deposits, expenses and add-backs are independently supported?
- What are the total rate, fee, term and exit costs?
- Can the file move from alternative, MIC or private financing back to A lending—and when?
Rajiv’s broker perspective
A self-employed mortgage should tell the complete business story without stretching the facts. I would first test the strongest supportable A or insured method, then compare alternative/B cash-flow approaches where appropriate. MIC or private financing can solve an equity or timing problem, but it should have a realistic exit. The goal is not to manufacture a larger income number; it is to match verified evidence with a lender whose policy understands the business.
