Greenbelt and Protected Land Rules for Ontario Property Owners

If you own or want to buy land inside the Greenbelt, the Oak Ridges Moraine or other protected countryside, you will hear that it is restricted. What that means in practice depends on the land's designation, its zoning and what you want to do.

This article explains the general rules that apply to rural and farmland severances and building, and the approvals that commonly overlap. For a specific parcel, the mapping and policies that apply to it need to be confirmed, since they differ from place to place.

Why protected land is hard to divide

A consent (severance) under the Planning Act is generally needed to sell, mortgage or charge part of a property, or to enter into any agreement about it lasting more than 21 years. Consents are granted by a municipal council or a body it delegates to, such as a land division committee.

The authority looks at whether the consent conforms with the official plan, whether the land suits the purpose, and whether there is adequate access, water supply, sewage disposal and protection from flooding. The decision must be consistent with the Provincial Planning Statement. If several severances are planned for the same area, the authority may decide a plan of subdivision is needed instead.

Prime agricultural areas and the surplus farm dwelling

Under the Provincial Planning Statement, 2024, new residential lots may not be created in prime agricultural areas except under policy 4.3.3.1.c), which covers residences that are surplus to a farm operation. This is the main reason rural residential severances on farmland are refused.

The exception is narrow. One new residential lot may be severed for a residence that is surplus to a farm operation after a farm consolidation. The lot must be the minimum size needed, and the planning authority must ensure that no new dwellings or additional residential units are permitted on the remaining farm parcel.

Greenbelt land is stricter again. Where the Greenbelt Plan applies to a surplus-dwelling severance, the planning authority must ensure that a residential dwelling is never permitted on the retained farm lot.

Extra homes on farmland

Planning authorities must permit up to 2 additional residential units in prime agricultural areas, subject to criteria. Those units cannot be severed into separate residential lots and must stay with the principal dwelling.

Permits that apply on top of planning rules

Even if planning rules allow your project, other approvals may be needed. A conservation authority permit is needed for development and some other activities in regulated areas, including floodplains, shorelines, wetlands and watercourses. The authority must confirm within 21 days whether a permit application is complete.

A municipal building permit is also needed for most new construction, and zoning is applicable law for that permit. If you need a zoning change or minor variance, no permit will issue until it is obtained. Farm buildings have their own path: smaller farm buildings of low human occupancy can be deemed to comply if built to Supplementary Standard SB-11, and a Minimum Distance Separation calculation is needed before a permit is approved.

Specific limits on land in the Oak Ridges Moraine, or the size of buffers around wetlands, depend on the land's mapping and the local rules, so confirm them for your parcel.

What to do next

• Ask the municipality which designations, zoning and overlays apply to your parcel.
• Ask the conservation authority whether the land is in a regulated area.
• Before buying, find out whether any consent or conditions already exist for the property.
• If you plan to sever, ask early whether the surplus farm dwelling exception could apply.
• Speak with a real estate or planning lawyer before signing an agreement that depends on a severance or permit.

If a consent is refused, the applicant can appeal to the Ontario Land Tribunal within 20 days of the notice of decision. Neighbours generally cannot appeal. That short window is a good reason to get advice early.
