Property Tax on Vacant Land in Ontario: How It Works

By Jatin Dua · Broker of Record, RE/MAX Quantum Realty · Updated 2 November 2026 · 9 min read — Vacant land in Ontario is taxed every year. Here is how MPAC values it, which rate applies, and how farm and forest programs can lower it.

This guide is for anyone who owns, is buying or has inherited vacant land in Ontario, from a building lot in Toronto to acreage in Caledon. It answers the basic question first, then explains how MPAC values land, which tax class applies, the programs that can cut the bill, and the tax surprises that hit when you build, using 2026 rates from official sources.

Is property tax applicable on vacant land in Ontario?

Yes. Vacant land in Ontario pays property tax every year, the same as land with a building on it. There is no general exemption just because a lot is empty.

The bill follows the same formula as any property: MPAC assessed value x the tax rate for the land’s property class. What changes with vacant land is the class. A residential building lot, a commercial site, a farm and a forest can all be “vacant,” but they are taxed at very different rates.

The land is taxed even if it earns nothing. That is the carrying cost every land buyer needs to plan for.

How does MPAC assess vacant land?

MPAC lists “vacant land that is available for residential use” as one of the property types in its residential class. For residential property, MPAC mainly uses the direct comparison approach: it compares your property with similar ones that sold in the area.

The timing matters. For the 2026 tax year, Ontario assessments are still based on values as of January 1, 2016. As of November 2026, the Province has not announced the next province-wide reassessment. So a lot bought in 2025 for far more than its 2016 value is usually still taxed on the older figure, unless something about the property changes.

If you think the assessed value or the class is wrong, contact MPAC before the deadline on your notice. My guide on why assessments still say 2016 explains how the frozen value feeds your bill.

What tax class is vacant land in, and what rate applies?

The class depends on zoning and use. The City of Toronto explains its own rules clearly:

• Low-density residential vacant land (lots for single-family or semi-detached homes) is taxed at the residential rate.
• High-density residential vacant land (such as a future condo site) is taxed at the multi-residential rate until the building is occupied, then at the residential rate.
• Commercial and industrial vacant land is taxed at a rate about 30% below the full commercial or industrial rate in Toronto.

Outside Toronto, the rules vary. In Peel’s 2026 schedule, for example, commercial vacant land in Mississauga, Brampton and Caledon carries the same total rate as other commercial property. Do not assume a discount without checking the municipality’s rate schedule.

Do farmland and land awaiting development get a lower rate?

Yes, in some cases. Land that is still farmed but is planned for development can fall into a farmland awaiting development subclass with a reduced rate. The discount is set locally, so it differs by city:

Worked example: a parcel in Brampton assessed at $1,000,000 in this subclass pays about $3,760 for 2026, compared with $12,534 at the full residential rate. The discount is tied to the development phase, so it can end as the land moves toward building.

Working farms are different again. Under Ontario’s Farm Property Class Tax Rate Program, eligible farmland is taxed at no more than 25% of the municipal residential rate. To qualify, the land must be assessed as farmland, used for a farm business with a valid Farm Business Registration number, and owned by Canadian citizens or permanent residents. Agricorp runs the program. The farmhouse and its lot are still taxed at the residential rate.

Can forest land lower your vacant land tax?

Ontario’s managed forest program can reduce tax on rural land that is kept as woodland:

• Managed Forest Tax Incentive Program. You need at least 4 hectares (9.88 acres) of forest on one property, and an approved 10-year Managed Forest Plan prepared or approved by a Managed Forest Plan Approver. Enrolled forest is taxed at 25% of the municipal residential rate. The deadline to add land for the next tax year is June 30.

The program does not cover a house or the land used with it. It also comes with commitments: a forest plan, a progress report in year five and a renewal after ten years. If you plan to build soon, these are rarely a fit. See my guide to Greenbelt and Oak Ridges Moraine land for what you can build on protected rural land.

Does Toronto’s Vacant Home Tax apply to vacant land?

No. Toronto’s Vacant Home Tax is charged on residential properties that sit empty, at 3% of the assessed value. The City says owners do not need to make a declaration for vacant land without a structure. An empty building lot is taxed only at its normal property class rate.

The picture changes the moment a house is on the lot. If you buy a house to tear down, the house is a residential property until it is demolished, and a declaration is required each year. The repairs or renovations exemption needs major work that kept the home unoccupied for at least six months of the year, done with any required permits and without unnecessary delay. My guide on buying a teardown to build in Toronto covers the timing.

What happens to property tax when you build on vacant land?

Your tax goes up once there is a building, but the bill often arrives late. MPAC has to assess the new building first, and then the municipality issues a supplementary tax bill for the added value.

The City of Mississauga explains it plainly: if your house was recently built and, at the time you bought it, you only paid taxes on the vacant land’s value, you will get a supplementary bill. It is prorated from the effective date of the new assessment, so it can cover months that have already passed.

Supplementary bills are separate from your regular interim and final bills, with their own due dates, so watch the mail after MPAC sends a change notice.

How much does it cost to hold a vacant lot each year?

Property tax is the biggest fixed cost, but not the only one. For a Toronto lot assessed at $700,000, the 2026 property tax is about $5,371 a year, or $448 a month. In Brampton, the same assessment at the full residential rate is about $8,774.

Other holding costs to budget for, which vary by property and are not set by the city:

• Insurance on the land.
• Interest on any land loan.
• Upkeep such as grass cutting, snow clearing and fencing, which your city’s property standards bylaw may require.
• Design and permit costs if you plan to build.

If you are still deciding, my step-by-step guide on how to buy a vacant lot in the GTA covers due diligence, and my guide to HST on land sales explains when HST is added to the price.

What to do next

1. Get the land’s MPAC assessment and property class from the latest tax bill or MPAC AboutMyProperty.
2. Look up the 2026 rate for that class on the municipality’s website and multiply.
3. If the land is farmed or forested, check eligibility for the farm, managed forest or conservation programs and note their deadlines.
4. If you plan to build, set aside money for a supplementary tax bill from the date of occupancy.
5. If you are selling land instead, read my guide on how to sell vacant land in Ontario.
