What is the difference between a HELOC and refinancing your mortgage in Canada?

A HELOC (Home Equity Line of Credit) is a revolving credit line secured against your home equity, separate from your mortgage. You draw on it like a credit card and only pay interest on what you use. Refinancing replaces your existing mortgage with a new one at a larger amount, giving you a lump sum at closing. HELOCs typically have variable rates tied to prime. Refinances can be fixed or variable and may offer lower rates but involve a full new mortgage qualification.

Is a HELOC rate higher than a mortgage rate in Canada?

Yes. HELOCs are priced at Prime rate itself (no discount below prime), currently around 5.20% (2026). Standard closed variable mortgages are priced at Prime minus 0.50–0.90%, or around 4.30–4.70%. The HELOC rate premium is typically 0.50–0.90% higher than a comparable mortgage, plus HELOCs are almost always variable — there is no fixed-rate HELOC option at most Canadian lenders.

Can a HELOC be called in Canada?

Yes. A HELOC is a demand facility — lenders can legally reduce your limit or require full repayment with relatively short notice (typically 30 days under most agreements). This happened to some borrowers during the 2008–2009 financial crisis when lenders tightened credit. For this reason, relying on HELOC access as a primary liquidity source or for long-term debt carries more risk than a structured mortgage.

What is the maximum HELOC amount in Canada?

As of the current OSFI guidelines, the maximum combined LTV for a mortgage plus HELOC is 80% of your home value. If your home is worth $700,000, the maximum combined outstanding (mortgage + HELOC) is $560,000. If your mortgage balance is $400,000, your maximum HELOC limit is $160,000. You also need at least 20% home equity to qualify for a HELOC.

What is the Smith Manoeuvre and does it require a HELOC?

The Smith Manoeuvre is a Canadian tax strategy that converts non-deductible mortgage interest into tax-deductible investment loan interest. It requires a readvanceable mortgage — a product that includes both a mortgage and a HELOC that automatically increases as you pay down the mortgage principal. Each mortgage payment reduces the principal, freeing up HELOC room, which is then immediately borrowed and invested. The investment loan interest is tax-deductible, while the mortgage interest is not. It does require a HELOC as the mechanism for re-borrowing.

How do you qualify for a HELOC vs a refinance in Canada?

Both require qualifying under the mortgage stress test (contract rate + 2%). For a HELOC, lenders typically require a minimum 20% equity, and the qualifying payments are usually based on the outstanding HELOC balance at the qualifying rate. For a full refinance, you re-qualify as a new mortgage — your income, credit, and LTV all reset.

HELOC vs Refinance in Canada: Which One Should You Choose? (2026)

HELOC vs Refinance: Side-by-Side Comparison

Feature	HELOC	Refinance
Structure	Revolving credit line	Lump-sum mortgage
Rate	Variable (Prime; typically 5.20%)	Fixed or variable (typically 4.24–4.84%)
Rate commitment	No term; rate floats daily	Fixed for term (1–10 years)
Access to funds	Draw anytime up to limit	One lump sum at closing
Repayment	Interest-only minimum; flexible	Amortizing (principal + interest)
Can lender call it?	Yes — demand facility	No — fixed term
Qualification	20%+ equity; stress test	20%+ equity; full mortgage qual
Maximum LTV	80% combined (mortgage + HELOC)	80% combined
Best for	Ongoing or uncertain needs	Specific large amount; want certainty

Rate Comparison: The Real Premium

In the 2026 environment (Bank of Canada rate 2.75%, Prime at 4.95%):

Product	Rate	Notes
HELOC	Prime + 0.00–0.50% = 5.20–5.45%	No discount below prime at most lenders
Variable closed (5-yr)	Prime − 0.65% = 4.30%	Discounted variable mortgage
Fixed closed (5-yr)	~4.44%	Standard 5-year fixed
Fixed closed (3-yr)	~4.24%	Shorter term, slightly lower

HELOC costs 0.75–1.15% more than a comparable mortgage. On $200,000 outstanding, that is $1,500–$2,300/year in extra interest.

How Qualification Differs

HELOC Qualification

Lenders qualify HELOC borrowers in two ways:

Interest-only basis: Monthly payment qualifying amount = HELOC limit × qualifying rate ÷ 12
Repayment basis (some lenders): Qualifying payment assumes 25-year amortization on the full HELOC limit

OSFI B-20 guidance: Lenders must stress test HELOC borrowers at the qualifying rate (contract rate + 2%, or 5.25%, whichever is higher).

Refinance Qualification

A full refinance resets your mortgage entirely. You qualify:

On the full new mortgage amount
Based on current income (must re-verify)
At the stress test qualifying rate
Against all existing debts (GDS/TDS ratios)

If your income has dropped since your original mortgage, a refinance may be harder to qualify for than an additional HELOC if you already have equity.

When Refinancing Makes More Sense

Situation	Why Refinance Wins
You need a large specific amount	Lump sum at closing, fixed rate, certain repayment schedule
You want a fixed rate	HELOCs are almost exclusively variable
You want long-term payment certainty	Refinance locks in rate for term; HELOC floats
You are consolidating high-interest debt	Folding debt into a fixed-rate mortgage reduces risk of HELOC rate rises
You don’t want the discipline challenge	HELOCs require self-discipline not to redraw; a mortgage forces paydown

When a HELOC Makes More Sense

Situation	Why HELOC Wins
Staged renovation (costs spread over 1–2 years)	Draw as needed; only pay interest on what you use
Bridge financing (buying before selling)	Short-term, flexible
Emergency fund backstop	$0 cost if unused; available if needed
Smith Manoeuvre implementation	Requires readvanceable product
Business owner covering seasonal cash flow gaps	Short-term draws, variable needs

The Callable Risk: Why Lenders Can Demand Repayment

A HELOC’s “on-demand” nature means your lender can:

Reduce your available limit with 30 days’ notice
Freeze draws immediately in a broader credit tightening
Require full repayment if your home value drops materially

This is not theoretical. During periods of housing market stress (2008–2009, regional declines), lenders have sent mass reduction notices.

Implication: Do not structure your financial plan around permanent HELOC access. Do not use a HELOC as your only emergency fund. A HELOC is a supplementary facility, not a guaranteed credit facility.

The Smith Manoeuvre: How the HELOC Makes Investment Interest Tax-Deductible

The Smith Manoeuvre is unique to Canada and exploits the CRA’s rule that interest on money borrowed to earn investment income is tax-deductible.

How It Works

Get a readvanceable mortgage (e.g., National Bank All-In-One, BMO Homeowner ReadiLine, TD FlexLine, Manulife One)
Each month you make a regular mortgage payment; a portion reduces your principal
As principal goes down, the HELOC component automatically frees up the same amount
You immediately draw that amount from the HELOC and invest it in income-producing assets (Canadian dividend stocks, ETFs generating dividends or interest)
You claim the HELOC interest as an investment interest deduction on your T1 return (Line 22100)
Over time, your non-deductible mortgage balance shrinks and is replaced by deductible HELOC debt

Smith Manoeuvre Tax Benefit Example

Parameter	Year 1	Year 5	Year 10
Readvanceable mortgage	$500,000	$450,000	$370,000
HELOC investment balance	$0	$50,000	$130,000
HELOC interest (5.20%)	$0	$2,600/yr	$6,760/yr
Tax deduction value (43% rate)	$0	$1,118/yr	$2,907/yr
Cumulative tax saved over term	—	—	~$17,000

Risks: Investment value is not guaranteed. HELOC balance grows regardless of investment performance. Works best with a long time horizon, disciplined execution, and a formal plan with a tax advisor.

HELOC Costs: Setup and Ongoing

Cost	Typical Amount
Legal/notary fees to register HELOC	$800–$1,500
Appraisal fee	$300–$500 (sometimes waived)
Annual fee (some lenders)	$0–$100
Inactivity fee	$0 (most lenders)
Interest rate on outstanding balance	Prime + 0–0.50%

A HELOC has no interest cost if unused — only the setup costs. This makes it a low-cost emergency facility to hold in reserve.
