The problem bank-statement lending solves
Some self-employed businesses are genuinely cash-flow healthy but run heavily on e-transfers, cash, or a mix of personal and business banking that a T1 or NOA badly understates — often newer businesses, or ones in cash-heavy trades, without two full years of clean corporate paperwork behind them.
What a B lender actually looks at
A defined period — commonly six to twelve months — of personal and/or business bank statements, using deposit activity as a proxy for revenue. A discount factor is generally applied to gross deposits to strip out transfers between the borrower's own accounts, loan proceeds, and other non-revenue deposits. The exact period and discount method are program-specific and should be confirmed with the individual lender rather than assumed to be standard across the category.
Why this sits with B lenders
OSFI's Guideline B-20, which governs federally regulated A lenders, expects a rigorous, verifiable standard of income documentation. Bank-statement lending is inherently closer to an estimate than a verification, which is exactly the kind of file that fits a B lender's wider, higher-priced guidelines rather than an A lender's tighter ones. Course 10, B-Lender & Alternative Underwriting, covers this whole category in depth; this module scopes it specifically as an income-documentation option for self-employed borrowers.
What still gets asked for
Even a bank-statement program typically still wants proof the business exists and is real — a business licence or incorporation document, a reasonable explanation for large or irregular deposits, and often the same two-year self-employment history threshold seen throughout the insured stated-income programs in the previous module.
Setting client expectations
Bank-statement lending is a genuine, useful solution to a real documentation gap, but it typically comes with a materially higher rate and a lender fee. It's usually best positioned as a bridge — often to a cleaner A-lender file once a second year of tax filings exists — rather than a permanent home, unless the numbers genuinely work for the client regardless.
