Quick answer
  • Eligibility is subject to the OSFI B-20 stress test, requiring qualification at the greater of 5.25% or your contract rate + 2%.
  • The process typically involves a mortgage refinance, not a simple 'conversion' switch.
  • Your Debt Service Ratios (TDS/GDS) must remain within lender guidelines, usually 39% GDS and 44% TDS.
  • Costs can include appraisal fees (approx. $300-$500), legal fees (approx. $1,000-$1,500), and potentially a discharge fee from your current HELOC lender ($300-$400).
  • The Bank of Canada's policy rate directly influences HELOC variable rates, making fixed rates attractive during rising rate cycles.

Converting a Home Equity Line of Credit (HELOC) balance to a fixed-rate mortgage in Canada involves a refinance process where the outstanding HELOC debt is incorporated into a new, traditional mortgage product. This allows you to lock in a predictable payment schedule and interest rate, shielding you from variable rate fluctuations.

This is not a simple internal transfer but rather a full mortgage application, requiring you to qualify under current lending guidelines, including the OSFI B-20 stress test.

Why would I want to convert my HELOC to a fixed-rate mortgage?

You would want to convert your HELOC to a fixed-rate mortgage primarily for payment stability and interest rate certainty. HELOCs typically have variable interest rates tied to the prime rate, which means your payments can increase significantly if the Bank of Canada raises its policy rate.

Locking into a fixed rate provides predictable monthly payments, making budgeting easier and eliminating the risk of rising interest costs over the mortgage term. This move is particularly common during periods of anticipated or actual interest rate hikes, offering peace of mind to homeowners concerned about financial volatility.

What is the process for converting a HELOC to a fixed mortgage?

The process for converting a HELOC to a fixed mortgage is essentially a mortgage refinance. First, you'll need to assess your current financial situation, including your credit score, income, and overall debt.

Next, you'll apply to a mortgage lender (which can be your existing bank or a new one, or through a mortgage broker) for a new fixed-rate mortgage. This new mortgage will pay off your HELOC balance and any existing first mortgage, consolidating them into one new loan. The lender will evaluate your application based on current stress test requirements and your debt servicing ratios. If approved, legal and appraisal processes will follow to finalize the new mortgage.

What are the eligibility requirements?

Eligibility requirements for converting a HELOC to a fixed mortgage are the same as for any new mortgage application. You must demonstrate sufficient income to qualify for the new fixed-rate mortgage under the OSFI B-20 stress test, which currently requires you to qualify at the greater of 5.25% or your contract rate plus 2%.

Your Gross Debt Service (GDS) ratio (housing costs as a percentage of gross income) and Total Debt Service (TDS) ratio (all debt payments as a percentage of gross income) must typically not exceed 39% and 44% respectively. Lenders will also assess your credit history, property value, and overall equity in the home. A strong credit score (typically 680+) and stable income are crucial.

What are the costs involved in this conversion?

The costs involved in converting a HELOC to a fixed mortgage can include several fees similar to a full mortgage refinance. Expect to pay for a property appraisal, which typically ranges from $300 to $500.

Legal fees for registering the new mortgage and discharging the old HELOC can be between $1,000 and $1,500. Some lenders may also charge a discharge fee for closing your HELOC, often around $300-$400. While some lenders might offer to cover certain fees, it's essential to factor these potential costs into your decision.

For example, if you have a $150,000 HELOC balance and decide to convert it to a fixed mortgage, you might incur $400 for an appraisal, $1,200 in legal fees, and a $350 HELOC discharge fee, totalling $1,950 in upfront costs. It's important to weigh these costs against the benefits of payment stability.

How does the OSFI B-20 stress test impact converting a HELOC?

The OSFI B-20 stress test significantly impacts your ability to convert a HELOC to a fixed-rate mortgage by determining your maximum borrowing capacity. You will need to qualify for the new fixed-rate mortgage at a higher rate than your actual contract rate.

Specifically, federally regulated lenders must assess your ability to make mortgage payments using the greater of either the Bank of Canada's five-year benchmark rate (currently 5.25%) or your contracted mortgage rate plus 2%. This means that even if you secure a fixed rate of 4.99%, you might need to qualify as if the rate were 6.99%, potentially limiting the amount you can borrow or requiring higher income to meet the stress test criteria.

What are the alternatives to converting my HELOC?

Alternatives to converting your HELOC to a fixed-rate mortgage include continuing with the variable rate, paying down the HELOC more aggressively, or exploring a blend-and-extend option if your HELOC is part of a readvanceable mortgage with a fixed-rate portion. If you anticipate interest rates to decline or remain stable, maintaining the variable rate could save you interest.

Accelerated payments directly reduce your principal balance faster, minimizing interest costs. Some lenders offer the option to 'lock in' a portion of your readvanceable HELOC into a fixed-rate segment without undergoing a full refinance, which can be simpler and less costly. Each option has its own financial implications based on market conditions and your personal risk tolerance.

Comparing HELOC vs. Fixed-Rate Mortgage (Post-Conversion)

The decision to convert hinges on balancing flexibility with predictability and risk. A HELOC offers unparalleled flexibility with revolving credit, but at the cost of variable payments. A fixed-rate mortgage provides stability and budget certainty, ideal for those seeking to insulate themselves from market fluctuations.

Consider your future financial goals, income stability, and comfort level with interest rate changes when making this choice. Many Canadians find the predictability of fixed payments appealing, especially when managing other financial obligations.

Converting your HELOC to a fixed-rate mortgage can be a strategic financial move to secure predictable payments and mitigate interest rate risk. Given the complexities of refinancing, including the OSFI B-20 stress test and various associated costs, it's highly recommended to seek professional advice.

Frequently asked

Can I convert part of my HELOC to a fixed rate?

Yes, some readvanceable mortgage products allow you to 'split' your mortgage, fixing a portion while keeping a HELOC segment. This offers a hybrid approach, combining flexibility with rate stability.

Do I have to use my current bank to convert my HELOC?

No, you are not obligated to use your current bank. In fact, exploring options with different lenders and through a mortgage broker can often yield better rates and terms for your new fixed-rate mortgage.

Will converting my HELOC trigger the stress test?

Yes, converting your HELOC into a new fixed-rate mortgage is considered a refinance. Therefore, you will be subject to the OSFI B-20 stress test, needing to qualify at a higher rate than your actual contract rate.

How long does it take to convert a HELOC to a fixed mortgage?

The process typically takes 4-6 weeks, similar to a standard mortgage refinance. This includes application, underwriting, appraisal, and legal procedures to register the new mortgage and close the HELOC.

What credit score do I need to convert my HELOC?

While requirements vary by lender, a good credit score (typically 680 or higher) is generally needed to qualify for competitive fixed mortgage rates and ensure approval during the refinance process.

Can I convert an uninsured HELOC to a fixed mortgage?

Yes, most HELOCs are uninsured, and you can convert an uninsured HELOC to an uninsured fixed-rate mortgage. Mortgage insurance from CMHC, Sagen, or Canada Guaranty is typically for purchases with less than 20% down, not refinances.

What if my home value has dropped since I got my HELOC?

A decrease in home value could impact your loan-to-value (LTV) ratio. If your LTV exceeds 80% with the new fixed mortgage, you might have fewer lender options or face higher rates, as this would fall outside conventional lending guidelines for an uninsured mortgage.

Is a fixed-rate mortgage always better than a HELOC?

Not always. A fixed-rate mortgage offers stability, but a HELOC provides flexibility and can be cheaper if variable rates remain low. The 'better' option depends on your financial goals, risk tolerance, and interest rate outlook.

Can I get a fixed-rate HELOC?

No, HELOCs by definition are revolving lines of credit with variable interest rates. You can, however, convert the HELOC balance into a separate fixed-rate term loan, often part of a readvanceable mortgage structure, or consolidate it into a new fixed-rate mortgage.

Will my monthly payment increase after converting to a fixed rate?

Your monthly payment could increase or decrease depending on your original HELOC rate and the new fixed rate you secure. The primary benefit is that the new payment will be stable for the entire fixed term, regardless of future prime rate changes.
