Ontario’s approach to land use planning has undergone a seismic shift over the past several years, and the trajectory continued through 2026. A series of legislative amendments to the Planning Act, combined with policy changes at the provincial level and ongoing activity at the Ontario Land Tribunal (OLT), have fundamentally altered the rules governing what can be built, where it can be built, and how quickly approvals can move.
For commercial property owners, investors, and developers, understanding the current regulatory environment is not just an academic exercise — it directly affects the value, development potential, and risk profile of the properties in their portfolios.
The Big Picture: More Density, Faster Approvals
The provincial government has consistently signaled one overarching objective: get more housing built faster. The legislative tools deployed to achieve this — including Bill 23 (More Homes Built Faster Act), Bill 97, Bill 185, and related amendments — have had significant downstream effects on commercial and mixed-use development.
Key changes that affect commercial landowners and developers include:
- Increased as-of-right density permissions in many urban and suburban areas, meaning that certain development projects can proceed without full zoning amendments
- Expanded transit-oriented development zones that allow higher density near major transit infrastructure, including GO stations and subway stops
- Reforms to site plan approval processes intended to reduce timelines for routine commercial development applications
- Changes to community benefit charges and development charges that affect the cost structure of new commercial projects
The Ontario Land Tribunal: A Different Animal
The Ontario Land Tribunal — created from the amalgamation of the Local Planning Appeal Tribunal (LPAT), the Conservation Review Board, and other adjudicative bodies — has become a central forum for resolving land use disputes in Ontario.
For commercial developers seeking to challenge a municipal refusal of a development application, or to appeal conditions imposed on an approval, the OLT is the relevant venue. The Tribunal’s jurisprudence continues to evolve, particularly around questions of provincial policy compliance, the appropriate density of development in proximity to transit, and the interpretation of the more recent provincial planning policies.
Engaging experienced land use counsel before initiating an OLT proceeding is essential. The process is quasi-judicial, involves expert evidence (planning reports, traffic studies, environmental assessments), and the timeline from filing to hearing can span many months.
The Planning Act and Municipal Official Plans
One of the most significant — and sometimes overlooked — effects of provincial planning reforms is the pressure on municipalities to update their Official Plans. The provincial government has required municipalities to bring their planning policies into conformity with provincial policies within specified timelines.
For commercial property owners, this means that Official Plan designations for your property may be changing — in some cases, opening new development possibilities that did not previously exist. A property zoned for low-density commercial use in an older Official Plan may be eligible for mixed-use or higher-density designation under an updated plan.
The reverse is also possible: in some cases, the provincial policy framework has constrained certain types of development that municipalities previously permitted. Understanding how the evolving Official Plan affects your specific property requires an analysis by experienced land use counsel.
Permitted Uses, Non-Conforming Uses, and Zoning By-Laws
Zoning by-laws set out in detail what uses are permitted on a given parcel — commercial retail, office, industrial, mixed-use — and the specific performance standards that apply (setbacks, height limits, parking requirements, etc.). When a property is used for a purpose that was permitted when the use began but is no longer permitted under a current by-law, it is considered a ’legal non-conforming use.'
Legal non-conforming uses can be continued, but they cannot generally be expanded. A commercial landlord with a non-conforming use should understand the limitations before spending on improvements or signing long-term tenants — particularly if the planned use of the space differs meaningfully from the registered non-conforming use.
Environmental Constraints and Schedule B Lands
In Ontario, certain lands are subject to environmental policies that constrain or prohibit development — including floodplains, wetlands, valleylands, and areas within the Greenbelt. Provincial planning reforms have adjusted the boundaries of some of these protected areas, generating significant controversy and legal uncertainty.
For commercial landowners whose properties are adjacent to — or within — environmentally constrained areas, the current regulatory environment warrants a detailed legal review. The boundaries of regulated areas can affect not only what can be built but also what can be sold, what financing is available, and what environmental liabilities may attach to the property.
Phase I and Phase II ESAs in Zoning and Development Applications
Environmental site assessments (Phase I and Phase II ESAs) are a standard part of commercial real estate due diligence, but they are increasingly relevant in the context of development applications as well. Municipalities and the province may require current ESAs as part of site plan approval or rezoning processes, particularly for properties with a history of industrial use.
A Phase I ESA is a records-based review that identifies potential sources of contamination. A Phase II ESA involves physical sampling and testing. If a Phase II reveals contamination, a Record of Site Condition (RSC) filed with the Ministry of the Environment may be required before development can proceed — a process that can add significant time and cost to a project.
Practical Implications for Commercial Property Owners
The legislative pace of Ontario’s planning reform era means that the rules affecting your commercial property may have changed since you last reviewed them. Here is what we recommend:
- Have a current zoning compliance review done on any property you are considering purchasing, developing, or refinancing
- Confirm whether any provincial planning policies or OLT decisions have changed the development potential of your property
- Review the status of your municipality’s Official Plan and whether it is being updated in response to provincial policy
- If you are pursuing a development application, engage land use counsel early — before the application is submitted — to structure the strongest possible case
Final Thoughts
Ontario’s planning landscape in 2026 offers genuine opportunities for commercial property owners and developers who understand the current framework. The legislative agenda has broadly favoured development and increased density — but the specifics are complex and continuously evolving. Legal counsel with experience in Ontario land use law is not a luxury for serious commercial real estate investors; it is a necessity.
