Vacant Home Taxes by Ontario City: Who Charges What in 2026 (and the Declaration You Can't Skip)

In Toronto, a single missed form can turn a home you live in into a $45,000 tax bill. That's the real story of Ontario's vacant home taxes — not the rate, but the declaration you can't skip.

There's no Ontario vacant home tax. The province handed the power to municipalities in 2024, and each city decides. Toronto charges 3% of assessed value, Ottawa and Hamilton 1% (Ottawa's now climbing for repeat vacancy), Windsor and Sault Ste. Marie have their own versions, and many cities charge nothing. But in every city with the tax, you must declare your home's occupancy every year — even if you live in it, even if you're exempt — and if you miss the deadline, the city automatically deems it vacant and taxes it.

This tracker shows who charges what, explains the declaration trap, de-confuses the municipal tax from the federal one, and flags the Toronto lien most buyers never check. It's a companion to the licensing and short-term-rental rules covered elsewhere in this cluster — a separate tax with its own calendar. A tracker and a method, not tax advice: rates and deadlines are dated July 2026, Ottawa's rate now escalates, so always verify against your city's own page.

There's No Ontario Vacant Home Tax — and the Declaration You Can't Skip

Ontario extended the authority to impose a vacant home tax to all single- and upper-tier municipalities in 2024, and published a Provincial Policy Framework to keep the programs broadly consistent. But it's not a provincial tax. Each city decides whether to adopt one and sets its own rate, rules, and deadlines — which is why the honest answer to "does Ontario have a vacant home tax?" is "some cities do, and yours might not."

The signature lesson is that the real trap isn't the rate — it's the mandatory annual declaration. In every city with the tax, every residential owner must declare occupancy each year, even if the home is their principal residence and even if they'd clearly qualify for an exemption. The declaration is how the city knows the home is occupied. Miss the deadline and the property is automatically deemed vacant and taxed — even though you lived there the whole time. Most owners owe nothing, as long as they declare on time; the people who get caught are the ones who assumed that living in the home meant they didn't have to do anything.

The scale of that trap is what makes it worth a whole article. A Toronto home assessed at $1.5 million carries $45,000 of exposure from one missed declaration, and even a modest home is deemed-vacant-and-billed if the form is late. This is the same municipal, patchwork pattern behind the municipal landlord licensing tracker and the short-term rental rules — a separate tax, but the same "verify your city" discipline, and the same reward for filing on time. It builds on the market picture in our best Ontario cities to buy a rental pillar.

Who Charges What — Toronto vs Ottawa vs Hamilton

Toronto — Vacant Home Tax, 3% of assessed value. The program launched at 1% in 2022 and was raised to 3% effective the 2024 taxation year, where it has held. A property is vacant if it was unoccupied for more than six months in the year; the declaration deadline is April 30, and the tax is payable in three instalments. A $1 million home means $30,000, a $1.5 million home means $45,000. The revenue funds affordable housing, and the program appears to be working as intended — vacant homes fell from 6,944 in 2022 to 5,989 in 2024.

Ottawa — Vacant Unit Tax, 1% (now escalating). Under By-law 2022-135, a unit is vacant if unoccupied 184 or more days; the declaration deadline is tied to the interim tax bill in mid-to-late March, with a $250 late fee. New for 2026: a graduated rate. It stays at 1% for a first-year vacancy but climbs 1% for each consecutive vacant year, capping at 5%. The city's audits found more than 1,200 undeclared vacant units in a single year, and the program has returned roughly 1,600 units to the market — supply the city estimates would have cost hundreds of millions to build new.

Hamilton — Vacant Unit Tax, 1%. Under By-law 25-201, a unit is vacant if unoccupied 183 or more days; the declaration deadline is April 15, with late declarations accepted until May 15 for a $250 fee, after which the property is deemed vacant. Bills go out in June, and unpaid amounts carry a 1.25% penalty plus 1.25% monthly interest. It applies to everything from detached houses to sixplexes.

And the rest. Windsor and Sault Ste. Marie have their own versions, and many Ontario cities have none at all. Always verify locally — the map of who charges is redrawn as councils adopt or decline. Remember, too, that this tax sits on top of the regular property tax you already pay, which varies widely by city; our property tax rates guide covers that base layer, and city-level context lives in our Hamilton neighbourhoods guide.

The Traps: The Federal Mix-Up, Exemptions, and the Toronto Lien

Municipal VHT is not the federal UHT. The federal Underused Housing Tax is a separate 1% tax that mainly targets foreign nationals and certain corporate or non-resident owners of Canadian residential property, with its own federal return. A regular Canadian resident living in their own home generally doesn't owe the UHT — but still must file the municipal declaration if their city has the tax. Two taxes, two filings; if you own through a corporation, a partnership, or as a non-resident, you may face both, so check each separately rather than assuming one covers the other.

Exemptions must be claimed and substantiated. Principal residence, tenanted, renovation, snowbird or medical care, ownership change, death of the owner — none are automatic. You claim the exemption on the declaration and prove it if the city audits; keep your records for years. The renovation exemption is the one that trips people up: it requires an actual building permit, not just work done, and retroactive permits can't be relied on.

The Toronto lien most buyers miss. Toronto's VHT attaches to the property, not the owner. A purchaser who doesn't confirm the VHT status before closing can inherit the vendor's unpaid tax — an expensive surprise at 3%. Confirming VHT status has become a standard due-diligence item on Toronto residential transactions, alongside the usual title and tax searches. This is adjacent to the broader tax-compliance discipline in our CRA audits guide — keep the records, and the surprises stay small.

Where This Is Heading — and How to Stay Ahead

The direction is clear: more cities are adopting the tax under the 2024 provincial authority, rates are rising (Toronto to 3%, Ottawa now escalating for repeat vacancy), audits are expanding, and enforcement is increasingly cross-referenced against other city data. Expect the map to grow and the penalties to sharpen.

The way to stay ahead is to treat the declaration as a fixed annual task — find your city's deadline, calendar it, and file every year even when nothing has changed. Document any exemption before the deadline, and check VHT status as part of any purchase. And read the policy for what it is: the tax rewards putting a home to use. For an owner sitting on an empty unit, renting it — even mid-term — usually costs far less than the escalating tax, which is exactly the outcome the policy is designed to produce.

Key Takeaways: Never Get the Deemed-Vacant Bill

Seven moves that keep the tax from surprising you:

1. Find out whether your city has a vacant home tax at all — many don't.
2. If it does, mark the declaration deadline (Toronto April 30, Ottawa mid-March, Hamilton April 15) and file every year, even if you live there.
3. Never assume occupancy is enough — a missed declaration is deemed vacant and taxed regardless.
4. Claim your exemption on the declaration and keep the documents — a renovation exemption needs a permit.
5. Don't confuse the municipal tax with the federal UHT — check whether you owe the federal one separately.
6. Buying in Toronto? Confirm the VHT status before closing — the lien follows the property.
7. Sitting on a vacant unit? Do the math — renting usually beats the escalating tax.

Quick win: look up your city's declaration deadline today and set a recurring reminder. Long game: the owner who files on time every year never gets the deemed-vacant bill.

The Bottom Line

There's no Ontario vacant home tax — the province handed municipalities the power in 2024, and each city decides. Toronto charges 3% of assessed value, Ottawa and Hamilton 1% (Ottawa's now escalating for repeat vacancy), Windsor and Sault Ste. Marie have their own, and many cities charge nothing. But the rate is the second story. The first is the declaration you can't skip: in every city with the tax, you must declare occupancy every year — even living in the home, even exempt — and a missed deadline means it's automatically deemed vacant and taxed, which on a Toronto home can mean $45,000 for a form you forgot. Don't confuse it with the federal UHT, document your exemption, and in Toronto treat the VHT as a lien to check before you buy. A tracker and a method, not tax advice; all figures are dated July 2026 and should be confirmed against your municipality's own page.

Frequently Asked Questions

Is there a province-wide vacant home tax in Ontario?

No. Ontario extended the authority to impose a vacant home tax to all single- and upper-tier municipalities in 2024, and published a Provincial Policy Framework to keep the programs consistent — but it's not a provincial tax. Each municipality decides whether to adopt one and sets its own rate, rules, and deadlines. As of 2026, Toronto charges a Vacant Home Tax of 3% of a property's assessed value, Ottawa and Hamilton charge a Vacant Unit Tax of 1% (Ottawa's now escalating for repeat vacancy), and Windsor and Sault Ste. Marie have their own versions. Many Ontario cities have no vacant home tax at all. Because councils add, change, and occasionally pause these programs, the only reliable approach is to check your specific city's current bylaw — don't assume a neighbouring city's rule (or the absence of one) applies to you.

Do I have to declare if I live in my home?

Yes — and this is the single most important thing to understand. In every Ontario city with a vacant home tax, every residential property owner must file an occupancy declaration every year, even if the home is your principal residence and even if you'd clearly qualify for an exemption. The declaration is how the city knows the home is occupied. If you don't file by the deadline, the city automatically deems the property vacant and issues the tax bill — even though you were living there the whole time. You then have to go through a complaint or appeal process to reverse it. Most owners owe nothing as long as they declare on time; the people who get caught are usually the ones who assumed that living in the home meant they didn't have to do anything.

What happens if I miss the declaration deadline?

The city deems your property vacant and charges the tax. In Toronto that's 3% of your assessed value — $30,000 on a $1 million home, $45,000 on a $1.5 million home — applied even if you actually lived there. There's usually a small late-filing charge and a short grace window (Ottawa and Hamilton accept late declarations with a $250 fee up to a second deadline, after which the property is deemed vacant), but once you're past that, you're into the complaint or appeal process to prove occupancy. False declarations carry their own penalties — Toronto's fine for a false declaration or failure to provide information runs up to $10,000 on top of the tax. The takeaway: the deadline matters more than almost anything else about these programs, so calendar it and file every year.

Is the municipal vacant home tax the same as the federal Underused Housing Tax?

No — they're two completely different taxes, and confusing them is common. The municipal vacant home tax (Toronto's VHT, Ottawa's and Hamilton's VUT) is charged by the city on residential property that sits vacant, and every owner in those cities files an annual occupancy declaration. The federal Underused Housing Tax (UHT) is a separate 1% federal tax that primarily targets foreign nationals and certain corporate or non-resident owners of Canadian residential property, with its own federal return. A regular Canadian resident living in their own home generally doesn't owe the UHT but still has to file the municipal declaration if their city has the tax. If you own through a corporation, a partnership, or as a non-resident, you may face both — check each one separately rather than assuming a single filing covers you.

Can a vacant home tax follow the property when it's sold?

In Toronto, yes. The Vacant Home Tax is a lien that attaches to the property itself, not just the owner who incurred it. That means a buyer who doesn't confirm the VHT status before closing can inherit the vendor's unpaid tax — a genuinely expensive surprise given the 3% rate. For that reason, confirming VHT status has become a standard due-diligence item on Toronto residential transactions, alongside the usual title and tax searches. If you're buying a home in a city with a vacant home tax, ask your lawyer to confirm the declaration and payment status as part of closing; if you're selling, make sure your declarations are current so you don't complicate the sale. As always, this is general information — your real estate lawyer handles the specifics.
