What Credit Score Do You Actually Need for a Mortgage in Ontario?

You typed the question into Google late one night: what credit score do you need for a mortgage in Ontario? And you were hoping for a clean number. 680. 650. Something to measure yourself against.

Here's the honest answer, from someone who's watched a lot of these files close: there isn't one.

Not because it's a trick question. Because the number doesn't work the way most people think it does. Your credit score doesn't decide whether you can get a mortgage. It decides which kind of lender fits your file right now — and that's a very different, much more hopeful thing.

The number sorts you into a lane, it doesn't lock a door

Canadian mortgage lending runs in tiers. Your score is the main thing that sorts you into one.

At the top are the A lenders — the big banks, credit unions, and monolines. Lowest rates, strictest rules. They also run the federal stress test, which qualifies you at the higher of your contract rate plus 2% or 5.25%, whichever is more.

Below them sit the B lenders — regulated alternative lenders like Home Trust, Equitable Bank, MCAN and Community Trust. They're flexible on credit and income, and they price a modest premium for that flexibility.

And then there are private lenders and MICs (Mortgage Investment Corporations) — individuals and syndicates who lend mainly against your home equity. Fastest, most expensive, shortest terms.

Move down the tiers and the rules loosen. A lower score doesn't mean no mortgage. It usually means a different tier — often as a bridge, not a destination. If your file sits in the lower bands, our guide to getting a mortgage with bruised or rebuilding credit walks through what each tier actually asks for.

Roughly where the bands fall

Treat these as a guide, not a rulebook. Lenders weigh the whole picture, and the cutoffs drift with the market. But this is the shape of it in Ontario:

Notice what that bottom row is really saying. Even below 600 — even in the months right after a consumer proposal, a discharge, or a stretch of missed payments — a mortgage can still fund if there's enough equity in the home. The B lenders and alternative lenders aren't bound by OSFI's stress test the way the banks are, which is exactly why they can approve files a bank has to decline.

The number matters less than four other things

Here's what surprises people. Two borrowers can have the identical score and get completely different answers. The score is a headline. Lenders read the whole story underneath it.

Recency

A late payment from four years ago barely registers. Three missed payments last month is a different conversation. Lenders care far more about what happened recently than what happened once, long ago. Time genuinely heals a credit file.

Equity and down payment

This is the big one, and it's the reason nobody can quote you a hard minimum. The more skin you have in the deal — a larger down payment, or real equity in a home you already own — the less the score has to carry. Private lenders will often go to roughly 75% loan-to-value (how much you're borrowing against your home's value) on a first mortgage almost regardless of score, because the equity is their security.

Income stability

Steady, provable income reassures every tier. If you're self-employed or your income is lumpy, that's not a dealbreaker — it just shifts which lender is the natural fit.

The story behind the dip

A divorce. A layoff. A health year. A business that hit a wall and recovered. Lenders in the B and private space are used to hearing real explanations, and a clear one you can document carries weight. The number tells them what. The story tells them why.

How to move up a band in a few months

If you're sitting just under a threshold, you're often closer than you feel. Credit scores can move meaningfully in a few billing cycles. A few habits do most of the work:

• Pay everything on time, every time. Payment history is the single heaviest factor. Even one on-time streak of a few months shows up.
• Keep your card balances under ~30% of the limit. Utilization is a big lever. Carrying $4,500 on a $5,000 card drags your score down even if you never miss a payment. Paying it down to under $1,500 can lift it.
• Don't scatter new applications. Every application for new credit can ding your score a little. Applying for three cards and a car loan while house-hunting works against you.
• If you're rebuilding from scratch, get a secured card. You put down a deposit, use it lightly, pay it off monthly, and it quietly rebuilds a payment history. It's one of the most reliable ways back up.

None of this is fast money, but it's real. A borrower who lands a B-lender mortgage today, keeps the payments clean for a year or two, and tidies up their utilization can often qualify at a bank on renewal. That's the whole point of the alternative tiers — a bridge back to bank rates, not a permanent address.

So, the real answer to your late-night question. There's no score that gets you a mortgage and no score that shuts you out. The number just tells you which door you walk through first — and, with a few good months, which door opens next.

Frequently asked questions

What is the minimum credit score for a mortgage in Ontario?

There isn't a fixed legal minimum. As a rough guide, around 680 and up opens most A lenders (banks and credit unions), roughly 600 to 680 is B-lender territory, and below 600 — or right after a credit event — equity-based private lending can still fund a mortgage. The score changes which lender fits, not whether a mortgage is possible.

Can I get a mortgage with a 550 credit score?

Often yes, if you have enough home equity or a solid down payment. At that level you're generally looking at a private or equity-based lender rather than a bank, because approval leans on the property's value instead of the score. It typically costs more and runs a shorter term, and it's best used as a temporary bridge while you rebuild.

How much does credit score affect my mortgage rate?

A lot, because it moves you between tiers. A file that qualifies at an A lender gets the lowest rates. B-lender pricing is typically about 1 to 2% higher, plus a lender fee around 1% of the mortgage. Private pricing is higher again. Raising your score enough to jump a tier is usually where the biggest savings come from.

How fast can I raise my credit score?

Faster than most people expect. Because payment history and credit utilization are heavily weighted, paying every bill on time and getting your card balances under about 30% of the limit can lift your score noticeably within a few billing cycles. Rebuilding from a serious credit event takes longer, but the trend line usually turns within months of consistent habits.

Does checking my own credit score lower it?

No. Checking your own score is a soft inquiry and has no effect on it. What can ding your score is a hard inquiry — the kind a lender runs when you apply for new credit. Applying for several new accounts in a short window while you're preparing for a mortgage is the thing to avoid.
