A-Lender vs B-Lender vs Private Mortgage: 6 Factors That Decide Where You Fit (2026)

Canadian lending runs on a ladder, and in 2026 there are 6 factors that decide which rung you land on: A-lenders (banks and monolines), B-lenders (alternative lenders), or private mortgages. Get the placement right and you pay the lowest cost your file can support — get it wrong and you either overpay or get declined. Here's how each factor sorts you. (For the basics first, read alternative lending in Canada.)

The short answer

Strong credit, provable income, and ratios inside the rules → an A-lender for the best rate. Good borrower who falls just outside bank rules (self-employed, healing credit, newcomer) → a B-lender at a small premium plus roughly a 1% fee. A time-sensitive problem with equity to protect → a private mortgage: fastest, most flexible, most expensive, and short-term. Always aim for the highest rung you genuinely qualify for.

The deciding factors:

• Credit score — how strong and clean your bureau is.
• Income provability — whether your income is fully documentable.
• Debt ratios — how your GDS/TDS measure against the rules.
• Rate & cost — the rate plus any lender or broker fees.
• Term length — how long the financing is meant to last.
• Exit plan — how and when you move back up the ladder.

1. Credit score

Credit is the first sorter. A-lenders want a strong, clean bureau — typically 680+ for the best pricing. B-lenders accept bruised or rebuilding credit, often in the 600s, if the rest of the file makes sense. Private lenders barely weigh score at all; they lend on equity.

A recent collection, a missed payment, or a low score doesn't end your options — it just shifts the rung. Many borrowers sit at B for a year or two while a blemish heals, then move up. If your credit is the issue, see bad-credit mortgage options for how placement works.

2. Income provability

What matters here isn't how much you earn — it's how cleanly you can document it. A-lenders need fully provable income: T4s, notices of assessment, and pay stubs. B-lenders flex on this. Private lenders care least, leaning on the property's equity instead.

This factor is decisive for the self-employed, whose tax returns often understate true cash flow after write-offs. A B-lender will review bank statements or accept stated income with a sensible story, getting a strong earner financed where a bank's rigid rules say no. Read more in self-employed mortgages.

3. Debt ratios

Lenders test affordability with two ratios: GDS (housing costs vs. income) and TDS (all debt vs. income). A-lenders hold you to standard limits and apply the stress test. B-lenders allow expanded ratios. For private mortgages, ratios are secondary to the equity in the home.

If your ratios are tight because of other debt, the answer is often a B or private mortgage that consolidates that debt into one payment, lowering your monthly obligations. That can reset your ratios enough to qualify back at an A-lender at the next renewal — which is the whole point of moving down a rung temporarily.

4. Rate and cost

Cost climbs as you move down the ladder. A-lenders offer the lowest rates with minimal fees. B-lenders charge a rate premium plus a one-time lender fee of roughly 1% of the mortgage. Private mortgages cost the most: higher rates plus lender and broker fees, reflecting the speed and risk.

The trade-off is access. Paying a B or private cost for a year is often far cheaper than not getting approved — or than forcing a bank application that gets declined and dings your credit. The mistake is paying private rates when you'd qualify for B. A broker prices all three so you don't overpay.

5. Term length

Term signals intent. A-lender terms run one to five years, commonly a five-year fixed, because you're meant to stay. B-lender terms are short — one to two years — a deliberate bridge. Private mortgages are usually one year, often interest-only, built for a quick in-and-out.

Matching term to plan matters. Locking a five-year term when you expect to refinance in 12 months can trigger a prepayment penalty. Taking a one-year private term when you need three years of breathing room sets up a scramble at maturity. The right term is the one that lines up with your exit.

6. Exit plan

The exit plan is what separates a smart placement from an expensive trap. Every step below an A-lender should be temporary, with a defined route back up. For most borrowers, a B or private detour lasts 12 to 24 months before they climb back to bank pricing.

The path looks like this: private to B once the urgent problem (arrears, a lien) is cleared and income stabilises; B to A after seasoning two years of clean payments and documenting income. A good broker plans this climb from day one — see how private mortgages fit a short-term plan. Without an exit, a temporary rate becomes a permanent cost.

Frequently asked questions

Is a B-lender bad?

No — B-lenders are legitimate, regulated, and often the smart choice for self-employed or credit-rebuilding borrowers. They cost a little more, but they finance good people who don't fit rigid bank rules, with a clear path back to A pricing once the file strengthens.

What credit score do you need for an A-lender in Canada?

Most A-lenders want at least 680 for the best pricing, though some approve from the low 600s with strong income and a larger down payment. Below that, a B or private mortgage is usually the realistic route while you rebuild.

How much more does a private mortgage cost?

Private mortgages carry the highest rates on the ladder plus lender and broker fees, reflecting the speed, flexibility, and equity-only basis. They're meant to be short — typically one year — so the goal is to refinance out as soon as you qualify for B or A.

Can I move from a private or B-lender back to a bank?

Yes — that's the plan. After clearing the urgent issue, stabilising income, and seasoning clean payments, most borrowers refinance up a rung at much better pricing. The climb usually takes 12 to 24 months.
