BMO Just Cut 46,000 Credit Lines. Here's Who's Next and How to Protect Yourself.

What Happens When 46,000 Canadians Wake Up to Slashed Credit?

BMO reduced credit limits for an estimated 46,000 Canadians in early 2026, targeting personal lines and credit cards with zero advance notice. The cuts affected customers with strong credit profiles, including those with 800+ scores and perfect payment histories, according to widespread reports across Canadian financial forums and news outlets.

A client came to see me two weeks before I filmed the video on this. She had a $25,000 personal line of credit with BMO. Good credit. Never missed a payment. Used it maybe twice in the last year.

She got a letter in the mail: credit line cut to $13,000. No phone call. No heads up.

The numbers coming out of BMO customers across the country are wild. A World Elite Visa holder saw their limit drop from $14,000 to $500. That is a 96% reduction. One person called BMO and was told: "There are 300 people on hold because you're not the only one."

This is not a glitch. And BMO is not the only bank doing it. If you're relying on a HELOC or line of credit as your financial safety net, you need to understand what is driving these cuts and whether your credit is exposed.

What Did BMO Actually Do to These Credit Lines?

BMO's official statement was corporate boilerplate: "We periodically review our card portfolio to improve alignment with our business strategy." Their closure letters were blunt. They cited the contractual right to close accounts at any time for any reason. The Financial Consumer Agency of Canada (FCAC) confirms that banks can legally reduce or cancel unsecured credit without prior notice.

Here are three of the most reported examples from BMO customers:

These are not edge cases. The common thread is not bad credit. It is low usage. Banks flag dormant accounts as capital they are holding for zero return, and in a tightening cycle, that capital gets reclaimed first.

Why Are Banks Tightening Credit in 2026?

Banks hold capital reserves against every dollar of unused credit on their books, per OSFI's Capital Adequacy Requirements. A $25,000 line of credit sitting dormant forces the bank to set aside capital for the full amount in case it gets drawn. Multiply that across millions of accounts and the drag on profitability is massive. That is the core of what happened at BMO.

But the context is bigger. Three forces are converging right now that make banks nervous about consumer credit exposure.

BMO's U.S. Reset Program

BMO is in the middle of a major restructuring. They are selling 138 branches to First Citizens BancShares, representing $5.7 billion in deposits and $1.1 billion in loans. The program is 90% complete as of Q1 2026, per American Banker. Unused credit lines are the cheapest and fastest thing to cut.

The Mortgage Renewal Wave

About 60% of all outstanding Canadian mortgages are renewing in 2025 or 2026. That is roughly 1.15 million mortgages coming up for renewal in 2026 alone, according to CMHC's 2026 Outlook. Five-year fixed holders face average payment increases of 15% to 20%. Banks see that incoming payment shock and they are pulling back on unsecured credit before it turns into bad debt. If you're one of those renewals, here's what the renewal wave means for you.

Household Debt at Record Levels

Canadian household debt sits at $3.21 trillion, with a debt-to-income ratio of 176.7% as of Q3 2025, per Statistics Canada's national balance sheet. That means $1.77 in debt for every $1 of disposable income. HELOC debt alone reached $179 billion, the highest since 2019. For homeowners already stretched thin, a credit reduction can trigger a chain reaction. Especially if you're house-rich but cash-poor.

What Are the 3 Red Flags Your Credit Line Is Next?

Here is the myth most people believe: "I have good credit, so my line is safe." That is wrong. BMO did not target bad credit. They targeted low usage. Banks are cutting based on portfolio cost, not individual creditworthiness. Here is what makes your account a target.

Red Flag 1: You Have Not Used It in 6+ Months

The single biggest predictor of a credit limit reduction is dormancy. If you have a credit line sitting unused, you are telling the bank you don't need it. Their response is straightforward: if you don't need it, they'll take it back.

One BMO customer had zero balance on multiple cards. All of them were slashed. The line was there as a safety net, and the bank removed it because safety nets that never get used cost money to maintain.

Red Flag 2: You Recently Closed Another Product with the Same Bank

One customer on RedFlagDeals closed their BMO checking account on February 7th. Four days later, credit limits were cut across every remaining product they held with BMO.

Banks look at your total relationship. When you start pulling away by closing accounts, reducing deposits, or moving products elsewhere, the bank reads that as disengagement. They pull back in response. Your relationship depth with a bank factors into how they assess the value of keeping your lines open. This is similar to how co-signing creates hidden risk: the bank sees the full picture of your relationship, even when you don't.

Red Flag 3: High Limits, Low Utilization

If you have a $25,000 line and you've never drawn more than $3,000, the bank sees $22,000 of capital held for zero return. In a tightening cycle, that is first on the chopping block.

This is counterintuitive. The standard personal finance advice is to keep utilization low. That still helps your credit score. But from the bank's perspective, an account with a large unused portion is a liability on their balance sheet with no upside.

How Do You Protect Your Credit Lines? 4 Moves That Work

These are the same recommendations I give to clients in my office in person. They're simple. But most people don't act on them until the letter shows up. Here's how to get ahead of it.

Move 1: Use It or Lose It, Strategically

Use every credit line at least once every 90 days. Even a $500 draw that you pay back the next week counts. The goal is to keep your account active so it does not get flagged as dormant.

Set a quarterly calendar reminder. Draw, pay back. That simple. Do this for every credit card and line of credit you hold, across every institution.

Move 2: Do Not Voluntarily Close Credit Products

If you have a card or line you don't use, don't close it. Closing reduces your total available credit, which can spike your utilization ratio and drag your score down. Worse, it can trigger the bank to review everything else you hold with them.

Leave dormant products open. Use them once a quarter with a small transaction. The annual fee on a card you rarely use is a small price compared to losing $20,000 in available credit.

Move 3: Separate Your HELOC from Your Mortgage

A lot of Canadians have combined mortgage and HELOC products. BMO's Readiline is one of the most common. The risk: if you want to move your mortgage at renewal to get a better rate, the HELOC is tied to it. You can't move one without dealing with the other.

When clients come to me for renewal, one of the first things I look at is whether we should separate the HELOC from the mortgage. A standalone HELOC with one lender and a mortgage with another gives you maximum flexibility. You can shop your mortgage aggressively at renewal without worrying about your credit line being affected.

Move 4: Diversify Your Credit Across Institutions

Don't rely on one bank for all your credit. If you have your mortgage, HELOC, personal line of credit, and credit cards all with one institution, a single policy change can affect everything at once.

The better setup: HELOC with one institution, personal line with another, credit cards spread across two. If one bank tightens, you have options. This is basic risk management, and most people don't think about it until they get a letter like the one BMO sent.

What Does This Mean If You're a Homeowner Approaching Renewal?

About 1.15 million Canadian mortgages are renewing in 2026, per CMHC. If you hold a combined mortgage-HELOC product, your renewal is the window to restructure. Banks are tightening. Renewal is when you push back and set up a structure that works for you, not just the bank.

If You Have a HELOC

Your secured line is safer than unsecured credit, but don't get complacent. Use it quarterly. Review your loan-to-value ratio. OSFI caps HELOCs at 65% LTV. If your property value dropped and your LTV crept up, you could face a reduction at renewal. Stay on top of your numbers. Understanding how home equity is actually taxed matters too, especially if you're planning to access it.

If You Have a Personal Line of Credit

Check your usage history right now. Have you touched it in the last six months? If not, draw on it this week and pay it back. That single action moves you out of the dormant category. Review all your accounts and make sure none are sitting idle.

If Your Payments Are About to Spike

The mortgage renewal wave is hitting at the same time as these credit cuts. Five-year fixed holders renewing in 2025-2026 face average payment increases of 15% to 20%. That is roughly $5,100 more per year. Combined with a credit reduction, that is a double hit to your financial flexibility. If you hold a variable rate mortgage, the rate environment is adding another layer of pressure.

Could This Affect the Broader Housing Market?

When banks pull back on unsecured credit, it removes a financial buffer that many homeowners rely on during tight months. That matters for the 2026 housing market, especially in cities where prices have already corrected. A homeowner who loses their credit line and faces a payment spike at renewal has fewer options. Some will sell.

At the same time, OSFI's new rental property rules are tightening the screws on investors. The combination of tighter credit, higher renewal payments, and stricter investor rules means the pressure is coming from multiple directions at once. If you own rental property financed with a HELOC, pay attention.

The Bottom Line

Banks tightening credit is portfolio management, not personal. But 46,000 Canadians learned the hard way that unused credit is not guaranteed credit. The legal framework in Canada gives banks broad discretion to reduce or cancel unsecured credit at any time. And in a climate of $3.21 trillion in household debt, a 60% mortgage renewal wave, and $19 billion in quarterly bank profits, they are exercising that discretion aggressively.

The moves to protect yourself are simple. Use your credit lines regularly. Don't close products voluntarily. Separate bundled products for flexibility. Diversify across institutions. These are not complicated steps. But they require awareness and action before the letter shows up.
