A readvanceable mortgage is one of the more flexible home-financing options available to Canadian homeowners, and it has grown in popularity for good reason. It blends a traditional mortgage with a line of credit that grows as you pay down principal. This guide explains how a readvanceable mortgage works, its benefits and risks, the recent rule change that affects how much you can re-borrow, and when an equity-based alternative may serve you better.
Short answer: A readvanceable mortgage combines a mortgage with a home equity line of credit, so as you pay down the mortgage principal, your available HELOC credit grows by the same amount, letting you re-borrow without a new application. Since late 2023, OSFI limits the re-borrowable portion to 65% of your home's value at federally regulated lenders. If you need to access equity above that, an equity-based home equity loan or second mortgage is often the better route.
What Is a Readvanceable Mortgage?
A readvanceable mortgage, also called a re-advanceable or combined loan plan, pairs a traditional mortgage with a home equity line of credit (HELOC). As you pay down your mortgage principal, the available credit on your HELOC increases, letting you re-borrow the funds without applying for a new loan. This gives you ongoing access to your home's equity and a high degree of flexibility.
In some cases, interest on the re-borrowed portion may be tax-deductible depending on how the funds are used, under a Canadian strategy known as the Smith Manoeuvre. This applies only in specific circumstances and the rules are complex, so always confirm your own situation with a licensed tax professional before relying on any deduction.
How a Readvanceable Mortgage Works
What changed: the 65% re-borrowing cap
Since late 2023, OSFI's Guideline B-20 limits the re-advanceable portion of these products to 65% of your home's value, down from 80%. Any lending above 65% LTV must now be amortizing and non-readvanceable, meaning the room above that line does not grow back as you pay it down. This applies to federally regulated lenders, so if you hold a readvanceable mortgage above 65% LTV, a portion of your principal payments now goes toward permanently reducing the balance rather than freeing up re-borrowable credit.
The Smith Manoeuvre
The Smith Manoeuvre is a tax strategy developed by Fraser Smith, a Vancouver Island financial planner, and introduced in his 2002 book. In general terms, it is a debt-conversion approach that repeatedly borrows home equity for investment purposes, so the interest on the investment borrowing may be tax-deductible while the original mortgage is paid down.
It is important to understand this is a leveraged-investing strategy. Borrowing against your home to invest carries real risk, including investment losses on money you still owe. It suits disciplined homeowners with stable finances and a long time horizon, and it is not right for everyone. Speak with a licensed financial advisor and tax professional before considering it.

Benefits of a Readvanceable Mortgage
- Flexibility: re-borrow funds without a new application, useful when you anticipate future expenses or opportunities.
- Cost savings: using the HELOC portion avoids the higher rates of credit cards or personal loans.
- Debt management: a strong tool for consolidating debt, paying off high-interest balances and lowering your overall rate.
- Investment access: equity can fund opportunities, though any leveraged investing carries risk and warrants professional advice.
- Emergency funds: a built-in HELOC gives you access to cash for unexpected medical costs or major repairs.
Before You Choose One, Weigh These
When an Equity-Based Loan May Fit Better
Readvanceable mortgages are prime-lender products with standard qualification requirements, and the 65% re-borrowing cap now limits how much room they offer at the banks. If your credit or income makes qualifying difficult, or you need to access equity above 65% of your home's value, an equity-based home equity loan or second mortgage is often the more accessible route, because approval is based mainly on your equity rather than your credit score.
