Ontario Expropriation Law Guide 2024

The Expropriation Framework in Ontario

Ontario expropriation law is governed primarily by the Expropriation Act, R.S.O. 1990, c. E.26. The Act establishes the procedure for compulsory acquisition of private property by the Crown, municipalities, and other statutory authorities, and — critically — establishes the right to full compensation for property owners whose land is taken.

The fundamental constitutional principle behind Ontario expropriation is that the state may take private property for public purposes, but must compensate the owner fully. The compensation framework is designed to make the owner whole — to put them in the same financial position they would have been in had the expropriation not occurred.

Statutory Authority Requirement

An expropriation in Ontario must be authorized by statute. The expropriating authority — a municipality, the Province of Ontario, a Crown corporation like Metrolinx, or another statutory body — must have legislative authority to expropriate for its specific purposes. Without statutory authority, purported expropriation is void. Common statutory authorities include the Ontario Highway Transportation Board Act, the Municipal Act, 2001, the City of Toronto Act, the Ontario Infrastructure and Lands Corporation Act, and transit-specific legislation.

The Expropriation Procedure Under the Act

Notice of Application for Approval (s.4)

The expropriation process begins when the expropriating authority registers or files an application for approval with the approving authority (typically a minister or municipal council). The owner receives a Notice of Application for Approval under s.4 — the first formal notice that expropriation is being considered.

Owner's Right to an Inquiry (s.6)

Upon receiving the Notice of Application, an owner (or any person whose lands may be injuriously affected) may object and request a Hearing of Necessity — a public inquiry before an Inquiry Officer appointed under s.7. The Inquiry Officer holds a public hearing to consider whether the expropriation is fair, sound, and reasonably necessary in the achievement of the objectives of the expropriating authority.

The Inquiry Officer reports to the approving authority with recommendations but the approving authority is not bound by the recommendations — it has discretion to approve or refuse the expropriation regardless of the Inquiry Officer's conclusions.

Notice of Expropriation (s.9)

Once the expropriation is approved, the expropriating authority registers a Notice of Expropriation against the land in the applicable land registry office under s.9. Registration vests title to the land in the expropriating authority — the owner retains a right to possession (subject to notice) and the right to compensation.

Offer of Compensation (s.25)

Within 3 months after the Notice of Expropriation is registered (or the date the owner vacates, if earlier), the expropriating authority must serve the owner with a written offer of compensation (s.25). The offer must be accompanied by an appraisal prepared by the expropriating authority's appraiser. The owner does not have to accept the offer — they may negotiate or proceed to ORCA arbitration for independent determination of compensation.

ORCA: Ontario Land Tribunal (formerly ORCA)

If the parties cannot agree on compensation, the matter is determined by the Ontario Land Tribunal (formerly the Ontario Municipal Board / Local Planning Appeal Tribunal; the expropriation arbitration function was historically within the Ontario Review Council for Arbitrations). The Tribunal determines the fair market value and all components of compensation — the process involves expert appraisal evidence from both sides and is analogous to a civil hearing.

The Full Compensation Principle

Section 13 of the Ontario Expropriation Act establishes the components of full compensation:

1. Market Value of the Land Taken

Market value is “the amount that the land might be expected to realize if sold in the open market by a willing seller to a willing buyer.” The value is assessed as of the valuation date — the earlier of:

• The date the Notice of Expropriation was registered; or
• One year before the first offer was made under s.25

Market value must reflect the highest and best use of the land — not just its current use. An agricultural parcel with development potential is valued at the price reflecting that development potential, not merely the agricultural value.

2. Damages for Injurious Affection (Land Taken)

Where only part of an owner's land is expropriated, the owner is also entitled to compensation for the decrease in market value of the remaining land caused by the severance and by the construction and use of the works. This is injurious affection for land remaining after a partial taking.

3. Disturbance Damages

Section 18 provides for compensation for damages for personal and business losses that are a natural and reasonable consequence of the expropriation — losses beyond the market value of the land itself. These include:

• Moving expenses and storage costs
• Business disruption during relocation
• Cost of finding and acquiring replacement premises
• Increased operating costs at the new location
• Lost business profits during the period of dislocation
• Employee severance if the business cannot be relocated
• Goodwill losses that cannot be transferred

Disturbance damages are available only to the extent they exceed the market value — they are meant to make up the shortfall where market value alone does not make the owner whole.

4. Reasonable Costs of Disturbance

Section 17 also provides for reasonable costs of legal and appraisal services incurred by the owner in negotiating and defending their compensation claim — a significant protection ensuring owners can afford expert representation in expropriation proceedings without bearing those costs personally.

Injurious Affection Without a Taking (s.21)

Section 21 of the Expropriation Act provides a separate right to compensation for injurious affection where no land is taken from the claimant. An owner may claim under s.21 where:

1. A public work is constructed or used under statutory authority
2. The construction or use injuriously affects the owner's land
3. The damage arises from the fact that the work was done under statutory authority (actionable but for the statutory authority)

Classic examples in Ontario include: residential properties experiencing significant noise, vibration, or access disruption from a new transit line or highway; commercial properties losing customer access due to road changes; properties experiencing flooding from infrastructure works. The key limitation: the damage must be to the land itself, not merely inconvenience or interference with the business — though some business losses flowing directly from damage to land may qualify.

Expropriation Valuation Methodology

Ontario expropriation appraisals use real property valuation methodologies:

• Direct comparison approach: Comparing the expropriated property to recent sales of comparable properties adjusted for differences in size, location, zoning, and condition
• Income approach: For income-producing properties, capitalizing the net operating income to derive value
• Cost approach: For special-purpose properties where market comparables are unavailable, estimating replacement cost less depreciation
• Development approach: For lands with development potential, estimating the value based on the anticipated development that a purchaser would be able to achieve

The development approach is particularly significant in Ontario's urban expropriation context — Metrolinx transit corridor acquisitions and municipal road widening projects often affect properties in high-growth areas where development potential is a major component of value.

Frequently Asked Questions

What is the full compensation principle in Ontario expropriation law?

The Expropriation Act entitles an owner to full compensation — market value of the land taken, damages for injurious affection to remaining land, disturbance damages for business and personal losses, and costs of legal and appraisal services. The principle is to make the owner whole as if the expropriation had not occurred.

What is injurious affection in Ontario expropriation law?

Injurious affection exists in two forms: (1) where land is taken — compensation for the decrease in value of the owner's remaining land; and (2) where no land is taken (s.21) — compensation for damage to land caused by construction or use of a public work under statutory authority, where the damage would have been actionable but for the statutory authority.

What is the expropriation procedure under the Ontario Expropriation Act?

The process: application for approval → Notice of Application served on owner → owner may request Hearing of Necessity → Inquiry Officer report → approval → Notice of Expropriation registered (vests title) → offer of compensation served within 3 months → negotiation or ORCA arbitration to determine compensation.

What are disturbance damages in Ontario expropriation?

Disturbance damages under Expropriation Act s.18 compensate for moving costs, business relocation expenses, lost profits during dislocation, cost of finding replacement premises, and other natural and reasonable consequences of the expropriation beyond the market value of the land itself.

How has Bill 23 affected Ontario expropriation law?

Bill 23 had limited direct impact on the Expropriation Act framework but affected planning approvals and development charges, which influence land value in expropriation proceedings. The valuation date for Ontario expropriations is the earlier of the Notice of Expropriation registration date or 1 year before the first compensation offer.
