Mortgage solution
A self-employed file isn’t harder, it’s just documented another way. Lenders go by what your returns show, not by what the business collects.

Two years of notices of assessment, your financial statements, the business records. The two-year average is the starting point. And a year that went down pulls harder than a year that went up.
Some lenders add back one-time expenses or part of the retained earnings. Others stick to declared net income, period. That gap moves the amount you qualify for a lot more than the rate does.
You don’t shop a file to every lender at once. Which lender gets it depends on the income proof you can produce, your credit and the property.
Documents to gather
For a mortgage, yes. Lenders use declared net income, so each dollar you optimize away on taxes shrinks what you can borrow. If a purchase is coming, talk to your accountant a year before. That does more than any rate negotiation.
Current rates
These rates are indicative. Yours depends on your file, the type of mortgage (insured or not) and the lender. And look at the penalty too, it matters as much as the number.
