Collateral vs Conventional Mortgage in Canada 2025

Understanding the critical difference between collateral charge and conventional charge mortgages — and why it matters at renewal.

When you get a mortgage in Canada, your lender registers a charge against your property at the land titles office. There are two types of charge registration: conventional (standard charge) and collateral. This distinction has significant implications for your flexibility, especially when it comes to switching lenders or accessing home equity — but most borrowers are never clearly told which type they're getting.

What Is a Conventional (Standard Charge) Mortgage?

A conventional mortgage is registered for exactly the amount you borrowed. If you borrow $500,000, a $500,000 charge is registered against your property. When you want to switch lenders at renewal, the new lender can take over this charge through an assignment — a straightforward, low-cost process.

Conventional mortgages are offered by most monoline lenders and some banks. They give you maximum flexibility because switching lenders at renewal requires minimal legal work and cost.

What Is a Collateral Charge Mortgage?

A collateral mortgage is registered for more than the amount you borrowed — typically up to 100-125% of your property's appraised value. If you borrow $500,000 on a $700,000 home, a collateral charge might be registered for $700,000 or even $875,000.

The logic is flexibility: the lender can advance you additional funds in the future (as a HELOC or additional loan) without re-registering a new charge. TD Bank, Tangerine, and National Bank register all their mortgages as collateral charges by default.

Critical drawback: Collateral mortgages cannot be assigned to a new lender. When you switch at renewal, the new lender must discharge your old charge and register a new one — requiring a lawyer, costing $1,000-$2,000, and eliminating the cost-free "switch" option that conventional mortgage holders enjoy.

The Hidden Switching Cost

One of the most significant advantages of a conventional mortgage is the ability to switch lenders at renewal for free (or for a small administrative fee absorbed by the new lender). Because the charge can simply be assigned, no lawyer or notary is needed.

With a collateral mortgage, switching always requires:

Total: $1,000-$2,000+ just to shop for a better rate at renewal. This switching cost effectively gives your current lender leverage to offer you a less competitive renewal rate, knowing you face friction to leave.

Readvanceable Mortgages and Collateral Charges

Many collateral charge mortgages are paired with a Home Equity Line of Credit (HELOC) to create a readvanceable mortgage product. As you pay down your mortgage principal, the available HELOC room increases automatically. Popular products include:

If you plan to leverage your home equity for investment, renovation, or other purposes as you pay down your mortgage, a collateral/readvanceable structure may be genuinely advantageous. If you simply want a straightforward mortgage and maximum renewal flexibility, a conventional charge is typically better.

Which Should You Choose?

Choose a conventional charge mortgage if:

Consider a collateral charge mortgage if:

Ask your lender explicitly: "Is this mortgage registered as a conventional or collateral charge?" Many borrowers discover they have a collateral charge only when they try to switch lenders at renewal and learn they face unexpected legal fees.

Frequently Asked Questions

Can I convert a collateral charge to a conventional charge?

Not without paying out your mortgage in full, discharging the collateral charge, and registering a new conventional charge at another lender. This is essentially refinancing, which may trigger penalties if done before term end.

Is a collateral charge mortgage bad?

Not inherently — it depends on your situation. It's bad if you want flexibility to switch lenders at renewal. It can be good if you want a bundled HELOC or plan to stay with the same lender and access equity over time.

What banks use collateral charges by default?

TD Bank and Tangerine register all mortgages as collateral charges. National Bank also uses collateral charges for most products. Most monoline lenders use conventional charges.

Does a collateral charge affect my credit?

The charge itself doesn't directly affect credit scores, but if it's bundled with a HELOC, that revolving credit limit appears on your credit bureau and can impact your debt-service ratios for future borrowing.
