How to Buy Development Land in Ontario: Approvals, Costs and Due Diligence

To buy development land in Ontario, a buyer should establish what can legally be built, how long and how costly the approvals will be, what servicing and environmental conditions attach to the site, and whether the project’s economics still work after every cost and delay is counted. Development land produces no income while it is held, so the purchase price is justified entirely by future value, which makes planning status, servicing, market demand and financing the central questions. This guide is for builders, developers, investors and owner-users evaluating vacant land or underused sites in the GTA and Southern Ontario. It covers how to assess a site, how the approvals process works, the costs beyond the price, due diligence, deal structure and the mistakes that most often turn a promising site into a costly hold.

Start With the Residual Land Value

The disciplined way to price development land is to work backward from the finished project. Estimate what the completed development would be worth, then subtract hard construction costs, soft costs (design, permits, legal, marketing), financing costs, development charges and other levies, a return for risk and profit, and the cost of carrying the land through approvals and construction. What remains is the most you can pay. Change the assumptions and test the result: longer approvals, higher construction costs, higher interest rates, lower sale prices or rents. A price that only works under optimistic assumptions is a warning. Because development land carries no income, our guide on how commercial property value is calculated in Ontario explains why land is priced differently from income property.

Assess the Planning Status

Ontario land use is regulated through layers. Understand where the site sits in each.

• Provincial policy: the Provincial Planning Statement, 2024, in effect since October 20, 2024, sets the provincial framework for growth, intensification and the protection of employment areas that municipalities implement.
• Official Plan: the municipality’s long-term designation for the site. A rezoning generally can only be approved if the new use conforms with the official plan.
• Zoning by-law: the permitted uses, density, height, setbacks and parking today.
• Other approvals: minor variances through the committee of adjustment, consent (severance), plan of subdivision, site plan control and, in some cases, conservation authority permits.

A site that already permits your project is worth more than one that needs an official plan amendment and rezoning, because approvals add time, cost and risk. Decisions on many approvals can be appealed to the Ontario Land Tribunal within time limits set under the Planning Act, which can extend timelines further, and the Planning Act provides for an appeal if a municipality does not decide a site plan application within the prescribed period. Speak with a land-use planner or lawyer to map the realistic path and timeline. Ask whether pre-consultation with the municipality has occurred, and what the municipality said.

Servicing, Access and Site Conditions

• Servicing: confirm water, sanitary and storm capacity, and who pays for extensions or upgrades. Lack of capacity can stall a project regardless of zoning.
• Access and transportation: road access, driveway approvals, turn lanes and any required road improvements.
• Soil, topography and drainage: a geotechnical investigation can reveal fill, poor soils or high groundwater that raise construction costs.
• Natural heritage and hazards: floodplains, wetlands, woodlots and other features regulated by the municipality or conservation authority, which can shrink the buildable area.
• Easements, utilities and encumbrances crossing the site.
• Neighbouring uses: noise, odour and separation requirements from industrial or transportation corridors.

Environmental Due Diligence

Environmental history matters greatly on development land, particularly where a former industrial, commercial or agricultural use is being replaced with a more sensitive use. A Phase I environmental site assessment, typically completed to the CSA Z768 standard or to Ontario Regulation 153/04 where it supports a Record of Site Condition, is the starting point. A Phase II involves sampling where concerns are found. In Ontario, a Record of Site Condition must be filed in the provincial registry before a property’s use changes to a more sensitive use, such as from industrial or commercial to residential, so a residential redevelopment of a formerly commercial or industrial site should build the time and cost for assessment and any cleanup into the price and schedule. Contamination can affect value, financing and liability, so negotiate its allocation with your lawyer before conditions are waived. See our due diligence checklist for the broader review.

Understand the Costs Beyond the Price

• Development charges and other levies: municipalities and school boards levy charges on new development under Ontario legislation, and there may be parkland dedication, community benefits and other requirements. Confirm current amounts and timing with the municipality, since they can be large and can change.
• Professional fees and studies: planners, engineers, architects, environmental and geotechnical consultants, legal fees, and application fees.
• Servicing and infrastructure: on-site works and any contributions to off-site works.
• Carrying costs: realty taxes, interest, insurance and security during approvals.
• Land transfer tax: on non-residential land, Ontario’s published rates are 0.5% up to $55,000, 1.0% from $55,000 to $250,000, 1.5% from $250,000 to $400,000 and 2.0% above $400,000, with an additional municipal tax in the City of Toronto.
• HST: sales of commercial real property are generally taxable, and where the purchaser is a GST/HST registrant it typically self-assesses the tax. Land and development transactions can raise particular HST questions, so obtain advice from your accountant and lawyer.

Structuring the Deal

Conditions are the buyer’s main protection on land. Consider:

• Due diligence conditions long enough for environmental, geotechnical, servicing and planning review.
• Approval conditions, in which closing depends on obtaining a rezoning or other approval, with an outside date and a clear mechanism if the approval is delayed or refused. Sellers will weigh this against price and certainty.
• Deposit structure and extensions, including what is refundable and when.
• Vendor cooperation: whether the seller will sign applications and allow studies on the site during the conditional period.
• Financing conditions where you are relying on a lender.

Have your lawyer draft these carefully. A loose approval condition can tie up either side.

Financing Land

Lenders view raw and partly approved land as higher risk than income property, since there is no income to cover payments. Expect lower leverage, shorter terms, higher pricing and requirements for reports, an appraisal, and evidence of the borrower’s experience and the project plan. Speak with a lender or mortgage professional early; see how to finance a commercial property in Ontario and the CapRate.ca mortgage page. Financing for construction is typically arranged separately once approvals are in place.

Common Mistakes When Buying Development Land

• Buying on hope of rezoning. Approvals are not guaranteed and can take longer than planned.
• Ignoring servicing capacity. Zoning does not create water or sewer capacity.
• Underestimating development charges and levies. They can materially change the residual value.
• Skipping geotechnical and environmental work. Ground conditions and contamination are expensive surprises.
• Not stress-testing the model. Test longer timelines, higher rates and lower sale prices.
• Weak conditions in the agreement. Protect against approval failure and delay.
• Overlooking carrying costs. Taxes and interest during approvals add up.

Frequently Asked Questions

How do I value development land?

By residual land value: the value of the completed project less all development costs, levies, financing and profit, tested against comparable land sales and stress-tested for delay and cost changes.

Should I buy land that needs rezoning?

Only if the price reflects the approval risk and time, and your agreement protects you if approvals are refused or delayed. Take planning advice before committing.

What is a Record of Site Condition?

A filing in Ontario’s environmental registry documenting a property’s environmental condition, required before a property’s use changes to a more sensitive use such as residential.

What are development charges?

Fees municipalities levy on new development to help pay for growth-related infrastructure and services, set under Ontario legislation. Confirm the current rates and timing with the municipality.

How long do approvals take?

It varies widely with the type of approval, the municipality and whether appeals arise. Get an informed estimate from a planner rather than assuming a timeline.

Can I get financing for vacant land?

Often, but with more conservative terms than for income property. Lenders assess the land, the plan and the borrower.

Conclusion

Development land rewards buyers who price from the finished project backward, verify planning status, servicing and environmental condition, and protect themselves with careful conditions. The best sites are not always the cheapest per acre; they are the ones where the approvals path, costs and timeline are understood. Before acquiring a commercial property, investors should understand not only the asking price, but also the property’s income, leases, expenses, physical condition and future potential.
