Before you buy land in Ontario, check the official plan designation and the zoning (including any exception, holding symbol or interim control by-law), whether the lot meets minimum frontage and area, whether it has municipal water, sewer and road access or will need a septic system and well, whether any part is regulated by the conservation authority (Ontario Regulation 41/24 regulates wetlands and 30 metres around them), whether it is in the Greenbelt or Oak Ridges Moraine, what is registered on title, and whether past uses mean contamination. If the zoning does not fit, a minor variance in Toronto costs $5,011.08 for a new house of three units or less in 2026; a rezoning starts at $63,679.83.

The checklist at a glance
| Check | Where to look | What can go wrong |
|---|---|---|
| Official plan designation | Municipal official plan maps | A rezoning can only be considered if the official plan allows the use |
| Zone, exceptions, H symbol | Municipal zoning map and by-law | Use not permitted, or permitted only after a holding symbol is lifted |
| Lot frontage, area, setbacks | Survey against the zone standards | Needs a minor variance before a permit |
| Services and access | Municipal engineering, utility locates | No sewer or water at the lot line; no open public road |
| Conservation regulation | Conservation authority mapping | Permit needed; building envelope shrinks |
| Greenbelt, Oak Ridges Moraine | Provincial plan maps, official plan | No new lots; limits near natural features |
| Title | Lawyer’s title search | Easements, rights-of-way, restrictions, encroachments |
| Past use | Phase One environmental site assessment | Contamination; record of site condition required |
| Trees, heritage | Municipal by-laws and heritage register | Tree permits; heritage approvals |
1. The official plan and zoning, read properly
The official plan sets what an area is for. The zoning by-law sets what you can build: uses, lot size and frontage, height, density, parking and setbacks. The Province’s guide makes the key point: council can only consider a rezoning if the new use is allowed by the official plan. If it is not, you are looking at an official plan amendment as well, and in Toronto that application alone costs $232,602.79 in 2026.
Read beyond the zone code. Look for site-specific exceptions, which can add or remove permissions. Look for a holding symbol, which allows a use but delays development until conditions such as services are met. Look for an interim control by-law, which can freeze some uses for a year plus a one-year extension while the municipality studies the area. In Toronto, the city also offers a zoning review that produces a Zoning Applicable Law Certificate for a specific plan.
2. What the Province now allows regardless of local zoning
Two provincial changes matter to residential lots:
- Additional residential units. On identified urban residential lands across Ontario, the Planning Act permits up to three units as of right: three in the main house, or two in the house and one in an ancillary building such as a garage or garden suite. The framework also removes or updates some local rules on angular planes, lot coverage, floor space index, minimum lot size and building separation. Setbacks and height can still require a variance.
- Site plan exemption for small projects. Following Bill 23, residential developments of 10 or fewer units are excluded from site plan control, except that the regulations allow site plan control where any part of the parcel is within 120 metres of a wetland, lake or river, including creeks and streams, or within 300 metres of an active heavy rail line.
Municipalities can go further. Toronto permits fourplexes city-wide and sixplexes in Toronto and East York and Ward 23; see buying land to build a multiplex in Toronto.
3. If the zoning does not fit: variance, consent or rezoning
| Tool | When it applies | Timeline in the Planning Act guide | 2026 fee, Toronto | 2026 fee, Mississauga |
|---|---|---|---|---|
| Minor variance | Small relief from a standard, such as a setback or frontage | Committee hearing; 20-day appeal period | $5,011.08 (new dwelling, three units or less); $2,228.98 (addition) | $1,361 (low and medium density residential zones) |
| Consent (severance) | Creating a lot, easement or lot addition | 90 days to decide once complete; 20-day appeal | $8,080.65 base; $6,561.48 per extra lot | $2,882 |
| Zoning by-law amendment | A use or scale the zone does not allow | Appeal if no decision in 90 days (120 with an official plan amendment) | $63,679.83 base plus $6.23 per m², capped at $779,441.52 | Not reviewed here |
A minor variance does not change the by-law; it excuses a specific requirement so a permit can be issued. For severances see lot severance in Ontario.
4. Services, access and soil
Ask the municipality what services exist at the lot line: water, sanitary sewer, storm sewer, and whether there is capacity. Confirm frontage on an open, maintained public road; a lot on an unopened road allowance or a private lane may not get a permit. Hydro and gas providers will tell you what a new connection needs.
On rural land, a septic system of 10,000 litres a day or less is designed and permitted under Part 8 of the Ontario Building Code, by the municipality’s building department or a health unit depending on where you are. Wells must be built by a licensed well contractor and recorded with the Province. Soil conditions set the size and cost of a septic bed; see septic and wells for rural buyers.
5. Water, the Greenbelt and the Moraine
Ontario Regulation 41/24, in effect since 1 April 2024, sets what conservation authorities regulate: hazardous lands, watercourses with a defined bed and banks, shorelines, wetlands and 30 metres around wetlands. Development in a regulated area needs a permit, tested against flooding, erosion, unstable soil and public safety. See conservation authority regulated land.
In the Greenbelt’s Protected Countryside, lot creation is discouraged and key features such as wetlands, streams and significant woodlands carry a minimum 30-metre vegetation protection zone. On the Oak Ridges Moraine, new lots outside Settlement Areas are very restricted. See what you can build on Greenbelt and Moraine land.
6. Title, trees, heritage and contamination
- Title. Your lawyer’s search shows easements, rights-of-way, restrictive covenants and registered agreements. Pair it with a current survey.
- Trees. In Toronto, injuring or removing a tree 30 centimetres or more in diameter on private property needs a permit under the Tree Protection By-law. A healthy protected tree can shape where a house or garden suite goes.
- Heritage. A designated property or a heritage conservation district adds a separate approval. See teardown or renovate a lakefront lot.
- Contamination. Former gas stations, factories and dry cleaners are the classic risks. Changing land to a more sensitive use, such as houses on a former industrial site, requires a record of site condition filed in Ontario’s Environmental Site Registry first, based on environmental site assessments by a qualified person.
7. Put a number on it
Every item on this list either confirms the value or takes something off it: a variance fee and a few months, a smaller building envelope, a septic bed, a cleanup. Price those into your offer. For the order of steps in an actual purchase, see how to buy a vacant lot in the GTA.

Land Valuation
What’s your land
worth today?
Three quick steps. Land doesn’t price like a house — what you’re allowed to build on it, how far along the approvals are, and whether services reach the lot line move the number more than anything else. This weighs all of them.

Frequently asked questions
How do I find out what I can build on a piece of land in Ontario?
Look up the official plan designation and the zoning on the municipality’s maps, then read the zone standards and any site-specific exception. Check for a holding symbol or interim control by-law, conservation authority regulation and provincial plans such as the Greenbelt. Then ask the municipality to confirm in writing; in Toronto, a zoning review can produce a Zoning Applicable Law Certificate for a specific plan.
What is the difference between a minor variance and a rezoning?
A minor variance, granted by the committee of adjustment, excuses a specific zoning requirement where the change follows the by-law’s general intent, such as a slightly smaller setback. A rezoning, passed by council, changes the by-law itself, usually to allow a different use or much more density. In Toronto the 2026 fees are $5,011.08 for a variance on a new dwelling of three units or less and $63,679.83 plus a floor-area charge for a rezoning.
How long does a rezoning take in Ontario?
The Planning Act lets an applicant appeal to the Ontario Land Tribunal if council has not decided within 90 days of a complete application and fee, or 120 days when it is filed with an official plan amendment. Those are appeal triggers, not typical approval times. Most rezonings take longer, especially where studies, public meetings or appeals are involved.
What does a holding symbol mean on a zoning map?
A holding symbol (H) means the zoning allows a future use but development cannot proceed until conditions are met, often services or roads. The municipality lifts it by by-law once the conditions are satisfied. In Toronto, the 2026 fee to apply to lift a holding symbol is $51,255.18. Until it is lifted, you cannot build what the underlying zone describes.
How close to a wetland can I build in Ontario?
Under Ontario Regulation 41/24, conservation authorities regulate wetlands and the 30 metres around them, so development there needs a permit. Other rules can be stricter: the Greenbelt Plan sets a minimum 30-metre vegetation protection zone around wetlands and other key features, and development within 120 metres needs an evaluation. Ask the conservation authority for its mapping on your lot.
