Alt-Doc Mortgage
An alt-doc mortgage is a mortgage qualified using alternative income documentation, such as bank statements or business records, instead of standard CRA tax filings..
An alt-doc mortgage is a mortgage that is qualified using alternative income documentation rather than standard tax filings such as a CRA notice of assessment or T4 slips. Instead, the lender reviews bank statements, business financial statements, invoices, or other records to estimate the borrower's income.
Who typically uses an alt-doc mortgage
Self-employed borrowers, contractors, business owners, and commission-based workers often show income on their tax returns that is lower than their actual cash flow, because of write-offs and deductions. Rather than relying on a single declared income line, an alt-doc lender builds an income picture through alternative income verification. Common documents include:
- Business or personal bank statements covering a set period
- Financial statements prepared by an accountant
- Invoices, contracts, or receipts
- GST/HST returns or other proof of declared revenue
Where alt-doc lending sits in the Canadian market
Most federally regulated lenders follow OSFI Guideline B-20, which expects sound income verification for uninsured mortgages. Alt-doc mortgages are therefore offered mainly by B-lenders, credit unions, and other alternative lenders. They generally carry higher rates and lender fees than an A-lender mortgage, because the lender accepts more documentation risk. The mortgage stress test can still apply, meaning the borrower may be qualified at a rate above the contract rate.
Why it matters to a borrower
Alt-doc lending opens the door to financing for people whose tax returns understate their cash flow, but it costs more. A borrower with strong business revenue and modest declared net income may qualify for a smaller loan than expected, or pay a rate premium. Down payment and equity requirements are often higher than on a standard high-ratio mortgage, and some programs consider net worth or assets alongside income.
Because documentation standards vary by lender, borrowers should compare offers and confirm in writing which proof of income is accepted. A similar approach appears in a stated income mortgage, though the two are not identical products.
Frequently asked questions
What documents are needed for an alt-doc mortgage in Canada?
Requirements vary by lender, but common items include several months of business or personal bank statements, accountant-prepared financial statements, invoices or contracts, and proof of GST/HST filing. Some lenders also review net worth or assets. Ask each lender for its accepted document list before applying, since standards differ across B-lenders and credit unions.
Are alt-doc mortgage rates higher than regular mortgage rates?
Typically yes. Because income is verified through alternative documents rather than standard tax filings, the lender takes on more risk and usually charges a higher interest rate plus a lender fee. The exact premium depends on the lender, the loan-to-value ratio, the property, and the borrower's credit profile. Compare total cost of borrowing, not just the rate.
Can self-employed borrowers qualify without standard tax documents?
Often yes, through an alt-doc or stated income program offered by alternative lenders and some credit unions. Lenders still assess credit score, down payment, property value, and debt service ratios. Qualifying is not automatic and the loan amount may be lower than a tax-filing-based approval would allow.
