HELOC vs Second Mortgage: Complete Canadian Comparison Guide

Accessing your home equity doesn't have to mean refinancing your entire mortgage. Canadian homeowners have two primary options—a Home Equity Line of Credit (HELOC) or a second mortgage—each with distinct advantages depending on your goals. Understanding the differences in rates, flexibility, and qualification can save you thousands and ensure you choose the right tool for your situation.

Understanding the Basics

Before diving into comparisons, let's clarify what each product actually is.

What Is a HELOC?

A Home Equity Line of Credit (HELOC) is a revolving credit facility secured against your home. Think of it like a credit card backed by your home's equity:

• You have a credit limit based on your equity
• You can borrow, repay, and borrow again
• Interest rates are typically variable (Prime + premium)
• You only pay interest on what you actually use
• Available up to 65% of your home's value (80% combined with mortgage)

What Is a Second Mortgage?

A second mortgage is a separate loan secured against your home, ranking behind your first mortgage:

• You receive a lump sum upfront
• Fixed monthly payments of principal and interest
• Often fixed interest rates
• Can access up to 85-90% of home value (higher than HELOC)
• "Second" refers to lien priority—if you default, the first mortgage gets paid before the second

The key distinction: a HELOC is a credit line you draw from as needed; a second mortgage is a loan you receive entirely upfront.

Detailed Comparison Table

HELOC Deep Dive

HELOCs are the most flexible way to access home equity, but that flexibility comes with considerations.

How HELOCs Work in Canada

Your HELOC limit is based on your home's appraised value minus your mortgage balance, up to 65% of value. As you pay down your mortgage, more HELOC room becomes available.

Example:

• Home value: $800,000
• Mortgage balance: $400,000
• Maximum HELOC: $120,000 (65% of $800K = $520K, minus $400K mortgage)

Many HELOCs are "readvanceable"—as you pay down your mortgage, your HELOC limit automatically increases.

Interest Rate Structure

HELOCs charge variable rates based on the prime rate:

• Bank HELOCs: Prime + 0.5% to Prime + 1%
• Credit union HELOCs: Often similar
• B-lender HELOCs: Prime + 1.5% to Prime + 3%

With Prime currently around 6.95%, expect HELOC rates of 7.45% to 8.45% for A-lender products.

Pros of HELOC

Flexibility: Borrow what you need, when you need it. Perfect for ongoing expenses like renovations done in phases or investment opportunities that arise.

Lower upfront costs: Minimal legal fees, often no appraisal required if attached to your mortgage.

Interest-only payments available: During the draw period, you can pay interest only—helpful for cash flow management.

Reusable credit: Pay it down, borrow again. No need to reapply for each use.

Integration with mortgage strategies: Essential for the Smith Manoeuvre and cash damming strategies.

Cons of HELOC

Variable rate risk: If rates rise, your costs increase immediately.

Discipline required: Easy access can lead to overspending. Many people treat it as "free money" and accumulate debt.

Lower maximum LTV: Capped at 65% of home value (80% total combined with mortgage), which may not access enough equity.

Repayment discipline: Interest-only payments mean the principal never decreases unless you actively pay it down.

Second Mortgage Deep Dive

Second mortgages provide lump-sum access to equity with predictable payments.

Position Priority Explained

"Second" refers to the lender's position if you default:

1. First mortgage holder gets paid first from sale proceeds
2. Second mortgage holder gets what's left
3. If proceeds don't cover both, the second mortgage lender loses

This added risk is why second mortgage rates are higher than first mortgage rates.

Why Rates Are Higher

Second mortgage lenders face:

• Higher risk of loss in default situations
• Less security than first position lenders
• Often dealing with borrowers who can't qualify with traditional lenders

Rates typically range from:

• Credit unions: 6-9%
• B-lenders: 8-12%
• Private lenders: 10-18%

Who Offers Second Mortgages

Banks: Rarely. Most prefer HELOCs for equity access.

Credit unions: Selective offerings, competitive rates for qualified borrowers.

B-lenders: Home Trust, Equitable Bank, CMLS, and others. More flexible qualification.

Private lenders: Most accessible but most expensive. Focus on equity, not income.

Pros of Second Mortgage

Lump sum access: Get the full amount upfront—ideal for specific projects with defined costs.

Fixed rate available: Lock in your rate for predictable payments regardless of Bank of Canada decisions.

Higher LTV possible: Access 80-90% of equity with B-lenders or private lenders (vs. 65% HELOC limit).

Easier qualification: Focus on equity means you can qualify with lower credit scores or non-traditional income.

Cons of Second Mortgage

Higher interest rates: Expect to pay 2-5% more than HELOC rates from A-lenders, more with private.

Less flexibility: Once you borrow, you're paying interest on the full amount even if you don't need it all immediately.

Higher fees: Legal costs, appraisals, and lender fees add up. Expect $2,000-5,000 in costs.

Fixed term pressure: Balloon payments at term end can create refinancing pressure.

Cost Comparison

Let's compare the true cost of accessing $100,000 in home equity over 5 years.

HELOC Costs Breakdown

Second Mortgage Costs Breakdown

The HELOC appears cheaper, but this assumes:

• You actually need the full $100,000 immediately
• HELOC rates remain stable
• You're disciplined about repayment

If you only need funds gradually, HELOC savings increase. If you need everything now and want rate certainty, the second mortgage premium may be worth it.

Qualification Requirements

HELOC Qualification

Most A-lenders require:

• Credit score: 650+ (680+ for best rates)
• Income verification: Full documentation required
• Debt service ratios: TDS under 42%
• Property: Owner-occupied preferred
• Equity: Sufficient to support requested limit

Second Mortgage Qualification

Varies significantly by lender:

Credit unions/B-lenders:

• Credit score: 550-650 acceptable
• Income verification: Some flexibility
• Focus: Balance of income and equity

Private lenders:

• Credit score: Often not a primary factor
• Income verification: Minimal
• Focus: Equity position and exit strategy
• Property: Location and marketability matter most

Use Case Scenarios

Home Renovations: Which Is Better?

For phased renovations: HELOC wins. Draw funds as contractors need payment, only pay interest on amounts used.

For contractor requiring upfront payment: Second mortgage may work better if you need the full amount at signing.

Recommendation: HELOC for most renovation projects.

Debt Consolidation: Comparing Approaches

HELOC approach: Lower rate than credit cards, flexible access, but requires discipline to actually pay down and not reuse.

Second mortgage approach: Fixed payments force paydown, can't reborrow, provides structure for those who need it.

Recommendation: HELOC if disciplined; second mortgage if you need forced structure.

Investment Property Down Payment

HELOC approach: Draw for down payment, interest may be tax-deductible if used for investment purposes.

Second mortgage approach: Larger amounts possible (higher LTV), fixed payments help cash flow planning.

Recommendation: HELOC for tax efficiency and flexibility; second mortgage if you need more equity access.

Emergency Fund Access

HELOC: Perfect for this. Set up a HELOC and don't use it—it costs nothing until you draw. Available instantly when needed.

Second mortgage: Makes no sense for emergency funds—you'd pay interest on money sitting unused.

Recommendation: HELOC is clearly superior for emergency access.

Large One-Time Expense

HELOC: Works but you'll need discipline to pay it down.

Second mortgage: Clear winner when you know exactly how much you need and want fixed payments.

Recommendation: Second mortgage for defined, large one-time needs.

When to Choose HELOC

A HELOC makes more sense when:

• You need flexible, ongoing access to funds
• You want lower upfront costs
• You have strong financial discipline
• You're comfortable with variable interest rates
• You want to combine with your mortgage (readvanceable)
• You're implementing the Smith Manoeuvre or cash damming
• You need an emergency fund backup

When to Choose Second Mortgage

A second mortgage makes more sense when:

• You need a specific lump sum amount
• You want payment predictability with a fixed rate
• You need higher LTV than HELOC allows (over 65%)
• Your credit score is below 650
• You have non-traditional income that's hard to document
• You need forced payment structure to ensure paydown
• You have an existing HELOC at maximum

Private Lenders and Second Mortgages

When banks say no, private lenders often say yes—but at a price.

When Banks Say No

Private lenders fill gaps when borrowers:

• Have credit challenges (bankruptcy, consumer proposal)
• Are self-employed with limited documentation
• Need more equity access than traditional products allow
• Have unique properties that banks won't finance
• Need fast closing that banks can't accommodate

Private Second Mortgage Rates

Expect to pay:

• Interest: 8-18% (most commonly 10-14%)
• Lender fee: 2-6% of loan amount
• Legal fees: $2,000-3,000
• Short terms: Typically 1-2 years

Exit Strategy Is Essential

Private mortgages are meant to be temporary. Have a clear plan to:

• Refinance with an A-lender when credit improves
• Pay off from sale of asset
• Refinance into conventional mortgage at term end

Without an exit strategy, you risk being stuck with expensive debt indefinitely.

FAQ

Can I have both a HELOC and second mortgage simultaneously?
Yes, though it's unusual. Your total debt cannot exceed lender limits (usually 80% LTV combined). Most people choose one or the other based on their needs.

Which has lower interest rates: HELOC or second mortgage?
HELOCs typically have lower rates because they're usually from A-lenders in first or second position with lower risk. Second mortgages, especially from B-lenders or private lenders, carry higher rates due to increased risk.

Can I convert my HELOC balance to a fixed rate?
Some lenders offer "fixed rate portions" within a HELOC, allowing you to lock segments at fixed rates while keeping the revolving feature. Ask your lender about this option.

What happens if I can't make payments on either product?
Both are secured by your home. Default can lead to foreclosure, though the first mortgage must be repaid before the second. HELOCs and second mortgages carry equal risk of losing your home.

Do I need an appraisal for both products?
HELOCs attached to your mortgage often use existing valuations. Standalone HELOCs and second mortgages typically require a new appraisal ($350-500).

Can I use either product for investment purposes?
Yes, and the interest may be tax-deductible if funds are used for income-producing investments. This is the basis of the Smith Manoeuvre strategy.

learn about the Smith Manoeuvre

Which is better for the Smith Manoeuvre strategy?
A HELOC, specifically attached to a re-advanceable mortgage. The Smith Manoeuvre requires reborrowable credit that grows as you pay down your mortgage.

How do HELOC and second mortgage affect my credit score?
Both add to your debt load and appear on your credit report. High utilization on a HELOC can negatively impact your score, similar to high credit card balances.

Can I pay off a second mortgage early without penalty?
It depends on the lender and terms. Private lenders often have open terms; B-lenders may charge penalties. Always review prepayment terms before signing.

What's the maximum I can borrow with each product?
HELOCs: Up to 65% of home value (80% combined with mortgage). Second mortgages: Up to 85-90% with B-lenders or private lenders, though costs increase significantly at high LTVs.

Making Your Decision

Choosing between a HELOC and second mortgage depends on your specific situation, goals, and financial discipline. Neither is universally better—they're different tools for different purposes.

Consider your needs carefully:

• Flexibility and ongoing access → HELOC
• Lump sum with predictable payments → Second Mortgage
• Maximum equity access → Second Mortgage (higher LTV available)
• Lowest cost for disciplined borrowers → HELOC
• Credit challenges → Second Mortgage (more accessible with B-lenders/private)

The right choice saves you money and helps you achieve your goals. The wrong choice costs you in fees, interest, or missed opportunities.
