When most people think about getting a mortgage, they picture going to one of the big banks—like RBC, TD, Scotiabank, or BMO. These are called A lenders or prime lenders, and they usually offer the lowest mortgage rates. But not everyone qualifies for a mortgage with a major bank.

That’s where B lenders come in.

What is a B Lender in Canada?

A B lender (also known as a subprime mortgage lender) is a financial institution that helps people who don’t quite meet the strict requirements of the big banks. They still offer mortgages—but with more flexible rules.

These lenders include:

Trust companies

Credit unions

Monoline lenders (non-bank mortgage companies)

Some private financial institutions

They’re fully licensed and regulated in Canada—just like the big banks—but they cater to borrowers who fall outside the standard lending guidelines.

Who Are B Lenders For?

B lenders are designed to help borrowers who are almost able to qualify for a mortgage with a bank but don’t quite meet all the requirements. This could be due to credit, income, or debt issues.

You might turn to a B lender if:

Your credit score is below 680

Your debt-to-income ratio is too high for the banks (above 39% for housing costs or 44% total)

You’re self-employed and don’t show consistent income on paper

You’ve had a recent consumer proposal, bankruptcy, or missed payments

You’re carrying a lot of credit card or personal loan debt

Let’s say you had a good mortgage with a bank a few years ago, but since then you’ve taken on more debt, or your credit score dropped due to missed payments. Even though you’re still working and paying your mortgage, you might now be seen as “too risky” for an A lender.

That doesn’t mean you’re out of options—it just means you might need to use a B lender to bridge the gap.

How Are B Lenders Different from Major Banks?

While both B lenders and traditional banks offer mortgages, the way they approve borrowers and structure loans is quite different. Here’s how:

Credit Score Requirements

Banks usually require a credit score of at least 680.

B lenders are more flexible and will often approve borrowers with scores between 500 and 679.

Debt-to-Income (DTI) Limits

Banks have strict limits: 39% for housing costs (GDS) and 44% for total debt (TDS).

B lenders can allow higher DTI ratios—sometimes over 50%—depending on the situation.

Income Documentation

Banks require full proof of income: tax returns, T4s, pay stubs, and notices of assessment.

B lenders may accept alternative documentation, especially for self-employed borrowers.

Interest Rates

Bank mortgages typically come with lower rates because they only lend to low-risk borrowers.

B lender rates are a bit higher to account for added risk.

Fees and Costs

Bank mortgages usually don’t come with lender fees.

B lenders often charge 1% of the mortgage as a lender or setup fee.

In short, B lenders give people a second chance when the banks say no. You may pay a bit more in the short term, but it can be the right move if you need to reset financially or rebuild your credit.

Interest Rates for B Lender Mortgages in Canada

B lenders take on more risk than traditional banks, so they typically charge a bit more. That doesn’t mean their rates are outrageous—just slightly higher to reflect your current financial profile.

Here’s what to expect:

Interest rates from B lenders are usually only slightly higher (i.e. 1%) than those offered by major banks.

If the major banks are offering 4.5%, B lenders might offer 5.5% depending on the lender, your credit score, income stability, and debt load.

You may also need to pay a lender fee (typically 1% of the loan amount) and possibly a broker fee, depending on the deal structure.

Even with slightly higher rates, many borrowers still come out ahead—especially if they’re consolidating high-interest debt like credit cards (which can charge 20%+ interest).

How to Get a B Lender Mortgage in Canada?

Applying for a mortgage with a B lender isn’t that different from working with a bank. You’ll still need to go through a proper approval process, but the rules are a bit more flexible.

Here’s what the process typically looks like:

1. Speak with a Mortgage Broker

The broker will review your situation—credit, income, property value, and debt—to determine whether a B lender is the best fit.

2. Gather Your Documents

While B lenders are flexible, they still want proof of your ability to pay. You’ll likely need:

ID and proof of address

Income documents (T4s, pay stubs, or bank statements if self-employed)

Property details (mortgage statement, tax bill, insurance)

3. Broker Submits to Lenders

Your broker will send your application to one or more B lenders who are a good match for your profile. Once approved, the lender sends a commitment letter with terms and conditions.

4. Appraisal and Legal Work

B lenders will require an appraisal to confirm the property’s value. Your broker will arrange this with an approved appraiser. After that, a real estate lawyer handles the closing paperwork.

Is It Bad to Get a B Lender Mortgage?

This is a common question—and the short answer is no, there’s nothing wrong with it.

In fact, many Canadians use B lenders as a temporary solution when they’re between major life events, fixing their credit, or adjusting their finances.

Here’s what usually happens:

A borrower gets a mortgage with a big bank

Over time, their debt increases (credit cards, lines of credit, personal loans)

Their credit score drops or their income changes

When it’s time to renew or refinance, they no longer qualify with the same bank

They move to a B lender until their credit improves

It’s more common than you might think.

In fact, mortgage brokers see this all the time—good borrowers who hit a rough patch and just need some time to recover. A B lender helps them stay in their home and reset financially.

Can You Move Back to a Bank Later?

Yes, absolutely. In many cases, a mortgage with a B lender is just a stepping stone.

Let’s say you get a 1- or 2-year mortgage with a B lender. During that time, you:

Pay down your debts

Make all your payments on time

Improve your credit score

Lower your debt-to-income ratio

By the time your term is up, your mortgage broker can reassess your file and see if you qualify again with a prime lender. If you do, they’ll help you switch back—often at a much better rate.

Why It’s Smart to Work With a Mortgage Broker

If you're unsure whether you qualify with a bank or need a B lender, the best thing to do is talk to a mortgage broker.

Mortgage brokers:

Know the qualification rules for dozens of lenders

Can match you with the right lender for your situation

Have access to both A and B lenders (plus private options)

Help you build a plan to get back to a prime mortgage

They’re not tied to one bank, so they work for you, not the lender.

Getting a B Lender Mortgage in Canada

There’s no shame in working with a B lender. Life happens. People change jobs, deal with illness, go through separations, or simply make mistakes with credit. What matters is how you move forward.

A B lender mortgage can:

Help you keep your home when banks say no

Give you time to rebuild your credit and finances

Offer you flexibility when your situation doesn’t fit a traditional mold

If you’re unsure whether you qualify with a bank—or if you’ve already been turned down—talk to a mortgage broker. They can walk you through all your options, including B lenders, private lenders, and even strategies to get back to the banks when you’re ready.
