Complete Guide to Canadian Mortgage Types

Understand how different mortgage structures—fixed, variable, insured, portable, and more—impact your payments, flexibility, and long-term financial plan

Why Mortgage Types Matter in Your Financial Plan

When shopping for a mortgage, it’s easy to focus on interest rates. But the type of mortgage you choose, how it’s structured and how it functions — can have an even greater impact on your monthly payments, financial flexibility, and total long-term costs.

In Canada, mortgages are categorized by repayment structure, insurance status, interest rate behavior, and flexibility. Choosing the right combination ensures your mortgage supports your lifestyle and financial goals — not the other way around.

Tip: Ask early: “How flexible is this mortgage if my plans change?” That one question can uncover more about your mortgage than the rate alone.

The Main Types of Mortgages in Canada

Most Canadian mortgages fall into the following key categories:

Conventional Mortgages

  • For down payments of 20% or more

  • No borrower-paid mortgage insurance required

  • Lower cost over time, though lenders may still insure them for internal risk management

High-Ratio (Insured) Mortgages

  • Required when the down payment is less than 20%

  • Must include mortgage loan insurance (e.g., CMHC), increasing cost but enabling earlier market entry

Fixed-Rate Mortgages

  • Interest rate stays constant for the term

  • Predictable, stable payments

  • Ideal for budget-conscious borrowers or those with low risk tolerance

Variable-Rate Mortgages

  • Rate floats with lender’s prime rate

  • Lower initial rate, but fluctuates over time

  • Requires comfort with payment variability

Adjustable-Rate Mortgages (ARMs)

  • Similar to variable-rate, but payment amounts change with interest rates

  • Keeps amortization steady but introduces month-to-month payment volatility

Open Mortgages

  • Can be paid off anytime without penalties

  • High flexibility, but typically higher interest rates

  • Suitable for short-term ownership or early repayment plans

Closed Mortgages

  • Offer lower rates in exchange for prepayment limits

  • Penalties apply for breaking terms early

  • Most common for long-term homeowners

Hybrid or Combination Mortgages

  • Blend of fixed and variable components

  • Offers partial protection from rate swings while allowing for some savings

  • Slightly more complex to manage

Home Equity Line of Credit (HELOC)

  • A revolving line of credit secured against home equity

  • Often paired with a mortgage or used post-purchase

  • Offers flexibility, but subject to rate increases and borrowing discipline

Comparing Mortgage Types by Borrower Goals

Mortgage Type Best For… Considerations
Fixed-Rate Stability, predictability May cost more upfront, but locks in peace of mind
Variable-Rate Long-term savings, rate strategy Requires ability to absorb changes in monthly payments
Adjustable-Rate Consistent amortization Payments may rise quickly in a rising rate environment
Open Short-term ownership, prepayment Flexible but carries higher rates
Closed Long-term homeowners Limited flexibility; penalties for breaking early
Hybrid Balancing risk and stability More complicated structure and rate tracking
HELOC Post-purchase borrowing flexibility Potential for overuse; rates are typically variable
 Choosing the Right Mortgage Type for You
 

The “best” mortgage type depends on:

  • Your income stability and cash flow

  • Your tolerance for interest rate fluctuations

  • Your expected homeownership timeline

  • Your need for flexibility versus certainty

For example:

  • A first-time buyer with limited cash flow may benefit from a fixed-rate, closed mortgage for predictable payments.

  • A buyer planning to sell or prepay early may prefer an open or hybrid mortgage.

  • Someone who wants to access funds for renovations might consider a HELOC-supported strategy.

Important: Even the best rate on the wrong mortgage type can lead to frustration, penalties, or financial strain. The structure must align with your goals and plans — not just your short-term budget.
