Severances and Consents in Ontario: How to Legally Split a Parcel of Land

Owning a large property in Ontario often comes with an appealing question: can you divide it and sell off a piece, build a second home, or create a lot for a family member? The answer is almost always yes — but not without navigating Ontario's land-use approval system first. Severance consent Ontario land division rules exist to protect community planning goals, infrastructure capacity, and neighbouring property values. Getting the process wrong can delay your project by months or expose a buyer to a title problem that clouds the sale years later.

This guide walks through what a consent to sever is, who grants it, what conditions you will likely face, and the mistakes buyers and sellers most commonly make. Ontario's Planning Act governs this area of law; municipal Official Plans and the Provincial Policy Statement layer on top of it.

What Is a Severance (Consent to Sever)?

A severance, formally called a consent to sever, is the approval needed under the Planning Act, R.S.O. 1990, c. P.13, to divide one parcel of land into two or more parcels — or to convey a part of a lot — without registering a plan of subdivision. Think of it as the smaller-scale alternative to subdivision: instead of creating dozens of lots through a formal survey plan, an owner splits off one or two parcels through a consent application.

Common situations that require a consent:

• Separating a farm lot to sell the back portion
• Carving off a vacant building lot beside an existing house
• Transferring a right-of-way, easement, or mortgage over part of a lot (these are also "consents" under the Act, even though no new lot is being created)

Committee of Adjustment vs. Land Division Committee

Two different bodies grant consents in Ontario, depending on the municipality.

Committee of Adjustment — most cities and large towns have one. It is a quasi-judicial body appointed by local council. In addition to minor variances from zoning by-laws, it hears consent applications.

Land Division Committee — in upper-tier or single-tier municipalities that have not established a Committee of Adjustment (more common in rural or county areas), the upper-tier municipality's Land Division Committee handles consents.

Both bodies apply the same legal test under s. 51(24) of the Planning Act, which also governs consents. Regardless of which body hears your application, you have a right to appeal the decision to the Ontario Land Tribunal (OLT).

When Is a Consent Required vs. a Plan of Subdivision?

A consent is appropriate when you are creating a small number of lots — typically one or two — and the municipality is satisfied that a full subdivision plan is not needed to manage servicing, road patterns, or community design. The planning authority has discretion to refuse a consent and require a subdivision plan instead if it believes the land should be developed comprehensively.

A plan of subdivision is required when creating multiple lots, extending a new public road, or where the municipality's Official Plan policies call for it (common for residential infill projects with more than two new lots).

Provincial Policy Statement Criteria

Ontario's Provincial Policy Statement (PPS) — issued under the Planning Act — sets the policy framework that every municipality must be "consistent with" when making land-use decisions, including consents. Key PPS principles that affect severances include:

• Directing development to settlement areas where services exist
• Protecting agricultural land and minimizing lot creation in prime agricultural areas (only limited types of agricultural-related severances are permitted)
• Protecting natural heritage systems, water resources, and hazard lands
• Supporting efficient use of infrastructure and public service facilities

A consent application that conflicts with PPS policy — for example, creating a rural residential lot on prime agricultural land — will typically be refused.

Lot Frontage and Lot Area Requirements

Each municipality's Zoning By-law prescribes minimum lot frontage (width at the street) and minimum lot area (total size) for the zone in which the land sits. The severed lot and the retained lot must each meet those minimums after the split. Common issues:

• A rural residential zone may require 30–60 metres of frontage; if the existing parcel is narrow, neither resulting lot may qualify.
• Agricultural zones often require 40 hectares minimum lot area, making residential severances impossible without an Official Plan amendment.
• In urban areas, a Committee may impose a slightly smaller lot if it issues a minor variance alongside the consent — but both approvals must be granted.

Conditions of Consent

When consent is granted, it almost always comes with conditions that must be satisfied before the consent lapses. Typical conditions include:

1. Parkland dedication or cash-in-lieu — the municipality may require a contribution toward parks, calculated as a percentage of land value.
2. Road widening — a strip of land along the frontage may need to be dedicated to the municipality to bring the road to its planned width.
3. Entrance permit — the Ontario Ministry of Transportation (for provincial highways) or the municipality must approve any new driveway access to the severed lot.
4. Servicing confirmation — proof that the severed lot can be adequately serviced (municipal water and sewer connection, or approval for a private well and septic system).
5. Reference Plan — the applicant is almost always required to deposit a Reference Plan (RP), prepared by an Ontario Land Surveyor, in the local Land Registry Office describing the boundaries of the severed parcel.
6. Solicitor's certificate or transfer — once conditions are met, the municipality issues a Certificate of Official (stamped deed), which is then registered on title.

Lapsing Period for Conditions

Under the Planning Act, conditions of consent must be fulfilled within one year of the date the consent decision is given (unless a longer period is specified). If conditions are not met in time, the consent lapses — it is void, and the applicant must reapply. This is a hard deadline; there is no automatic extension.

Greenbelt and Oak Ridges Moraine Restrictions

If the land falls within the Greenbelt Area (governed by the Greenbelt Act, 2005 and the Greenbelt Plan) or the Oak Ridges Moraine (governed by the Oak Ridges Moraine Conservation Act, 2001), severance rules are significantly more restrictive:

• New lot creation in the Natural Heritage System and Agricultural System of the Greenbelt is generally prohibited.
• The Oak Ridges Moraine Plan prohibits most severances in its Natural Core and Natural Linkage areas.
• Even outside the restricted designations, Provincial Plans add additional criteria that local committees must apply.

Always confirm whether a property is inside these overlays before relying on a projected consent timeline.

The Role of a Survey and Reference Plan

A Reference Plan (RP), sometimes called a deposited plan, is a survey drawing prepared by a licensed Ontario Land Surveyor and deposited at the Land Registry Office. It assigns a Part number to each parcel being created (e.g., Part 1, Plan 58R-12345). The deed conveying the severed lot will describe the land by reference to that Part and Plan number.

The Reference Plan is not the same as the title transfer — it simply gives the land a precise, registered legal description. The actual transfer of ownership still requires a Transfer/Deed of Land registered in the Electronic Land Registration System (ELRS).

Step-by-Step: Title Registration After Consent

1. Satisfy all conditions of consent (servicing, entrance permit, parkland, etc.).
2. Have an Ontario Land Surveyor prepare and deposit the Reference Plan.
3. Obtain the municipality's stamped Certificate of Official confirming conditions are met.
4. Have your real estate lawyer prepare the Transfer/Deed of Land describing the severed parcel by its RP Part number.
5. Register the transfer in ELRS — the severed parcel now has its own title record (PIN).
6. Confirm the retained parcel's title is updated to reflect the reduced boundaries.

Common Mistakes Buyers Make with Outstanding Consent Conditions

Buyers of recently severed lots — or buyers of the retained parcel — frequently encounter these pitfalls:

• Purchasing before the consent is final. If you agree to buy a "to be severed" lot before the consent is granted, the deal is conditional on something outside both parties' control. Make sure your Agreement of Purchase and Sale contains a proper condition.
• Missing the lapsing deadline. If the seller has not satisfied conditions and the one-year period expires before closing, the consent is void. Your lawyer should verify that the Certificate of Official has been issued before waiving conditions.
• Assuming services are in place. A building permit cannot issue until servicing conditions are met. Buyers sometimes purchase a severed lot expecting to build immediately, only to discover the well or septic approval is still outstanding.
• Ignoring Greenbelt or Moraine overlays. A lot may have been validly severed but still face tight restrictions on what can be built because of environmental designations that survive the consent process.
