Local Improvement Charges on Your Property Tax Bill in Ontario: What Buyers Should Know

Most line items on a property tax bill are easy to understand — they fund the general services a municipality provides. A local improvement charge is different. It's tied to a specific, one-time project that benefited a specific property or group of properties, and the balance can outlast the owner who was there when the project was approved.

If you're buying a resale home, understanding local improvement charges — and knowing how to check whether one applies — is a small but genuinely useful piece of due diligence.

What a Local Improvement Charge Is

A local improvement charge is a cost a municipality adds to a property's tax bill to recover the cost of a specific local infrastructure project that benefits that property, rather than the municipality as a whole. Municipalities generally spread the cost of these projects over a number of years rather than billing it all at once, which is why the charge shows up as an ongoing addition to the tax bill rather than a single lump-sum invoice.

Why It Appears on the Property Tax Bill, Not a Separate Invoice

Because the charge is collected alongside regular municipal property tax, it can be easy to overlook — it doesn't arrive as its own distinct bill with its own label demanding attention. Instead, it's folded into the total amount owing on the tax bill, which is exactly why it's worth specifically looking for rather than assuming the tax bill total is entirely made up of ordinary annual tax.

The Key Feature: It Runs With the Land

The detail that matters most for buyers is that a local improvement charge is typically tied to the property itself, not to the individual who owned it when the charge began. That means if there's a remaining balance still being paid off when a property sells, the charge — and the obligation to keep paying it — can carry forward to the new owner, rather than ending with the seller who benefited from the original project.

This is a meaningfully different situation from an ordinary annual tax bill, which simply reflects the current year and doesn't create a multi-year obligation attached to the land regardless of who owns it.

How to Find Out If a Property Has One

A local improvement charge, if one exists, should be identifiable through the standard tax certificate your lawyer orders from the municipality as part of closing due diligence. This is one of the specific things a tax certificate is meant to confirm, alongside the general tax account balance and any arrears.

Because it's easy to assume a tax bill is "just tax," it's worth explicitly asking your lawyer to confirm whether any local improvement charge appears on the certificate for a property you're considering, particularly for older homes or homes in areas where recent municipal infrastructure work has taken place.

Who Pays the Remaining Balance When a Property Sells

Handling of an outstanding local improvement charge balance can vary and is often addressed specifically in the Agreement of Purchase and Sale or through negotiation between the parties, rather than following one automatic rule in every deal. In some transactions, the seller pays out the remaining balance at closing; in others, the buyer knowingly assumes it as part of the deal, often reflected in the negotiated price. Because there's no single universal outcome, this is exactly the kind of detail to have your lawyer flag and address explicitly — not just leave to chance.

Negotiating This Before You Sign

If a tax certificate or your own inquiries reveal a local improvement charge with a meaningful remaining balance, it's worth raising before you're locked into the Agreement of Purchase and Sale, since it affects the true cost of the property. Waiting until after signing narrows your options considerably. A lawyer reviewing the agreement before you sign can help make sure this kind of detail doesn't get missed.
