Home equity lines of credit have become considerably more appealing since the Bank of Canada began cutting rates in 2024, offering some relief to homeowners who watched their HELOC rates climb past 7% over the previous two years. The question a lot of Canadians are sitting with now is whether to keep riding the variable rate down or lock into a fixed term before conditions shift again – and the honest answer depends on math that most rate articles skip over. From our experience, the lock-in decision is rarely as straightforward as lenders make it sound, particularly when fixed rates remain elevated relative to where variable rates have already landed. This piece covers where HELOC rates actually stand heading into 2026, how the conversion math works, and the specific circumstances where locking in makes genuine sense.
Where HELOC Rates Actually Sit in 2026
HELOC rates in Canada are almost always priced at prime plus a spread. As of mid-2026, the Bank of Canada’s policy rate sits in a range that has pushed the major bank prime rate to approximately 5.45%. Most stand-alone HELOCs at the big five banks are priced at prime + 0.50%, landing around 5.95% for well-qualified borrowers. Some lenders â particularly credit unions and smaller monoline lenders â are advertising spreads as low as prime + 0.25%, which puts their best rates closer to 5.70%.
That is a meaningful improvement from the peak in late 2023, but it is still not cheap money. A $150,000 HELOC balance at 5.95% costs you roughly $743 per month in interest if you are carrying it interest-only â which is how most Canadians actually use these products day-to-day.
How Lenders Set Your Spread
Your personal spread above prime depends on your credit score, your loan-to-value ratio, and whether the HELOC is stand-alone or bundled into a readvanceable mortgage. Borrowers with scores above 760 and less than 65% LTV typically get the best pricing. If your home has appreciated significantly and you have not refinanced lately, it is worth calling your lender to see if your spread can be renegotiated â some lenders will do it without a full refinance.
Stand-Alone HELOC vs. Readvanceable Mortgage: What Is the Difference?
This distinction matters more than most people realize, both for your rate and for how much flexibility you actually have.
| Feature | Stand-Alone HELOC | Readvanceable Mortgage (e.g., Scotia STEP, TD Home Equity FlexLine) |
|---|---|---|
| Maximum borrowing limit | Up to 65% of home value | Up to 80% of home value (combined with mortgage) |
| Rate type | Variable (prime + spread) | Variable HELOC portion + fixed or variable mortgage portion |
| Revolving credit | Yes | Yes â HELOC portion replenishes as mortgage is paid down |
| Ability to convert to fixed | Limited; usually requires a new product | Can convert HELOC draws to fixed sub-accounts at most lenders |
| Typical setup cost | Legal fees ($700â$1,500) | Legal fees + potential discharge/setup fees if switching lenders |
| Tax deductibility (investment use) | Yes, for eligible borrowed funds | Yes, but requires careful tracking of sub-accounts |
| Portability | Generally not portable | Generally not portable; tied to the property |
If you have a readvanceable mortgage, you likely have more options right now. Most major lenders allow you to convert a portion of your HELOC balance into a fixed-rate term loan sub-account without triggering a full refinance. That is the mechanism most relevant to the “should I lock in” question.

The Lock-In Calculation: When Fixed Actually Saves You Money
Converting a HELOC balance to a fixed-rate term is not free. You give up flexibility â a HELOC lets you pay down and redraw as needed; a fixed term loan does not. So before you lock in, you need to run the actual numbers.
Here is a simplified comparison for a $200,000 balance over 36 months:
| Scenario | Rate | Monthly Interest Cost | Total Interest Over 3 Years |
|---|---|---|---|
| Stay variable (HELOC at prime + 0.50%) | 5.95% | ~$992 | ~$35,700 (assuming flat rates) |
| Convert to fixed 3-year term | 5.49% | ~$915 (P+I on amortizing basis) | ~$29,800 (interest portion only) |
| Variable if rates drop 1% further | 4.95% | ~$825 | ~$29,700 (assuming full drop by month 6) |
The table illustrates the core tension: if rates stay flat or rise, locking in wins. If the Bank of Canada cuts another 75â100 basis points over the next 18 months â which some economists consider plausible given global softness â staying variable ends up in roughly the same place, with the added benefit that you kept your credit line flexible.
Fixed Rate Options Available Right Now
As of mid-2026, lenders converting HELOC balances to fixed sub-accounts are generally offering terms in the range of 5.29% to 5.79% for 2- to 5-year fixed terms. The sweet spot for most borrowers weighing certainty against cost is the 2- or 3-year fixed, which gives you a reasonable hedge without locking in for too long if rates continue to fall. Check with your lender directly â these conversion rates are often not posted publicly and there is some room to negotiate, especially if you are a long-standing customer with multiple products.
Tax Implications When You Use a HELOC for Rental Property or Investments
This is where Canadian HELOC strategy gets genuinely interesting â and where getting it wrong costs you real money at tax time.
The Canada Revenue Agency allows you to deduct interest on money borrowed for the purpose of earning income. If you use HELOC funds to purchase a rental property, buy eligible investments, or fund a business, the interest is generally deductible against that income. If you use the same HELOC to renovate your principal residence or pay for a vacation, that portion is not deductible.
Keeping the CRA Happy: Tracking Mixed-Use Draws
The trap most homeowners fall into is mixing purposes on the same credit line. If you draw $50,000 for a rental property down payment and then later draw $10,000 for a kitchen reno, you need to be able to prove to the CRA which funds went where. The cleanest approach:
- Use separate sub-accounts or separate bank accounts for investment-purpose draws versus personal use
- Keep a clear paper trail â wire transfers with notes, separate statements
- Never let investment-use funds pass through a personal account first if you can avoid it
- If you have a readvanceable mortgage, the sub-account structure actually helps here â you can designate one sub-account for investment use and track it independently
The Smith Manoeuvre â a tax strategy where Canadians convert non-deductible mortgage debt into deductible investment debt over time â uses HELOC mechanics specifically for this purpose. It is worth understanding if you have significant home equity and are also investing in non-registered accounts. See our overview at NorthMarkets Finance for more background.
Locking In and Tax Deductibility
Converting an investment-purpose HELOC draw to a fixed-rate term loan does not change the deductibility of the interest â what matters is the original purpose of the borrowed funds, not the form of the loan. So if it makes financial sense to lock in on an investment-use balance, you do not lose your interest deduction by doing so. Always confirm your specific situation with a tax professional, particularly if you have mixed-use borrowing.
What to Watch for in the Second Half of 2026
The Bank of Canada’s rate path is the single biggest variable in this decision. A few things worth monitoring:
- Bank of Canada announcements: The remaining scheduled decision dates for 2026 are in September, October, and December. If the Canadian economy softens further â particularly if U.S. trade tensions drag on exports â additional cuts remain on the table.
- Canadian housing market: A significant decline in home values would not directly affect your existing HELOC rate, but it could affect your available credit limit and your lender’s willingness to extend new credit.
- Lender spread adjustments: In a falling rate environment, some lenders quietly widen their spreads to protect margins. Check your actual statement â if your rate is not tracking prime moves as expected, ask your lender to explain.
- Renewal cycles: If you are also carrying a fixed-rate mortgage that renews in 2026 or 2027, your HELOC decision should be made in the context of your full borrowing picture, not in isolation.

Honest Takeaway: When to Lock In, When to Leave It Variable
Locking in makes sense if:
- You have a large balance ($100,000+) that you know you will carry for at least 2â3 years and you are not planning to pay it down aggressively
- Your cash flow is tight and you genuinely need payment certainty â a fixed term amortizes the balance and forces paydown
- You believe rates are more likely to stay flat or rise than to fall further
- You are financing a rental property or investment and want to lock in a known deductible interest expense for budgeting purposes
Staying variable makes more sense if:
- You plan to pay down the balance within 12â18 months â the flexibility of a HELOC is worth more than the rate difference over a short window
- You use the HELOC as a revolving tool (draw, repay, draw again) â a fixed term loan eliminates that entirely
- You expect further Bank of Canada cuts and are comfortable with the rate risk
- The spread between your current variable rate and the available fixed term is less than 50 basis points â the math rarely favours locking in at that margin
There is no universally right answer here. The decision comes down to your balance size, your time horizon, your cash flow needs, and your honest assessment of where rates are headed. Run the numbers for your specific balance before making a move, and if you have investment-use borrowing in the mix, loop in a tax professional before you restructure anything.
