Budget 2026 Will Make the Bank of Canada Publish Insured Mortgage Rates: What It Means at Your Renewal

Three measures, three different stages

The budget language is precise, and the precision matters. According to Budget 2026, Chapter 3, the government "proposes to establish new regulations to enhance publicly available information on insured mortgage rates, to be published by the Bank of Canada." The stated purpose is that better and more timely information will help borrowers compare and shop for the best available rates.

That is a proposal. The regulations still have to be written, and the budget sets no date for them. The prepayment-penalty item is one step earlier still: the government announces only its intention to consult industry and stakeholders on potential reforms, and only for insured mortgages. The optional-insurance change is also proposed rather than enacted.

The reading from Canadian Mortgage Trends lines up with the text. The budget leaves open which rates would be published, how often the data would be updated and when publication would begin, and it gives no start date for the higher insurance cap.

Here is the status ledger, which is the most important thing to get right before acting on any of it.

The information gap is the product

Renewal is where lenders have the most pricing power. Switching takes paperwork, appraisals and sometimes legal fees, so many borrowers sign the first offer that arrives. The lender knows this. A published benchmark does not force anyone's rate down, but it gives the borrower a reference point that does not come from the lender making the offer.

That reference point matters more this fall than it did in the spring. The Bank of Canada raised its policy rate by 25 basis points to 2.5% on Oct. 28, its first increase since July 2023, and said a further increase could be needed. Its next scheduled decision is Dec. 9.

Variable-rate borrowers felt it within a day. National Bank raised its prime rate to 4.70% effective Oct. 29, and the other large lenders moved prime in step from 4.45%.

Fixed renewal offers had already been climbing for weeks, because they follow the five-year Government of Canada bond yield rather than the policy rate. All six of the big banks lifted fixed rates by as much as half a percentage point over roughly five weeks into early October, as reported by money.ca. When rates move week to week, the offer in your renewal letter can be stale by the time you read it.

Homeowner.ca has tracked how those moves landed on a typical balance in All Six Big Banks Have Now Raised Fixed Rates, Adding $3,300 to a $500,000 Renewal.

What a quarter point is worth

The case for a benchmark rests on a simple question: how much does it cost to accept an offer that is slightly worse than the market? We ran the numbers on a $500,000 balance using Canadian semi-annual compounding, starting from a best-available five-year fixed rate of 4.44% listed by Ratehub.ca as of Oct. 29, 2026. The starting rate is illustrative; the gap is what matters.

A quarter point sounds like rounding. On a typical renewal it is roughly $800 a year in extra payments, and those dollars go to interest rather than principal.

That is the job a benchmark does. It does not tell you the right rate. It tells you whether the offer in front of you is in the neighbourhood of what other insured borrowers are paying, or a quarter point above it.

Three buckets, one benchmark

The budget says "insured mortgage rates," and that word is doing a lot of work. Canadian mortgages fall into three pricing buckets, and a published insured-rate series would describe only one of them directly.

An insured mortgage carries default insurance from CMHC, Sagen or Canada Guaranty. The common case is a home bought with less than 20% down: as the Financial Consumer Agency of Canada explains, a down payment under 20% typically means buying mortgage loan insurance.

That rule exists because the Office of the Superintendent of Financial Institutions generally restricts federally regulated lenders from lending more than 80% of a property's value without insurance. If you paid a premium at purchase, often rolled into the loan, your mortgage is insured, and it generally stays insured at renewal as long as you do not increase the balance or extend the amortization.

An insurable mortgage had 20% or more down but meets the insurance rules, so the lender can choose to insure it in bulk at its own expense. That is what the budget calls "optional" mortgage insurance. These loans usually price close to insured rates.

An uninsurable mortgage cannot be insured at all. Since the 2016 rule changes, as the Bank of Canada's 2017 Financial System Review summarized, homes priced over $1 million, amortizations longer than 25 years and mortgage refinances are prevented from being insured under those low-ratio rules. That captures a lot of existing owners: anyone who has taken equity out through a refinance, for instance, has typically moved into this bucket.

The spread between buckets is real. One comparison from WOWA.ca shows a best five-year fixed of 4.34% for insured borrowers against 4.69% for insurable borrowers with 20% down, and uninsurable loans priced higher still. Those are point-in-time figures, but the direction is consistent: insured money is the cheapest money.

So the benchmark will be most precise for the borrowers who were most constrained at purchase. For uninsured owners it becomes a floor: if your offer sits well above the published insured rate, the gap is not automatically unfair, but you should be able to get a clear explanation of what it is pricing.
