Leasehold Improvements in Ontario: Who Pays and Who Owns Them?

“Leasehold improvement” is a broad term covering most additions, renovations, or fixtures a tenant installs in a rented commercial space. It can include flooring, interior partitions, lighting, built-in millwork, a custom kitchen in a restaurant unit, or an entire buildout of an otherwise unfinished “shell” space. What exactly counts as a leasehold improvement, as opposed to a tenant’s own movable equipment or trade fixtures, is defined by the lease rather than by any single rule that applies across every commercial tenancy in Ontario.

This distinction matters because the consequences that follow — who pays, who owns the result, and what happens at the end of the term — are all tied to that definition. Our overview of how Ontario commercial leases work touches on improvements briefly as part of the broader lease structure; this guide looks specifically at how the money, ownership, and end-of-term obligations are typically handled.

Many commercial landlords offer a tenant allowance, sometimes called a tenant inducement, as an incentive to sign the lease — essentially a contribution toward the cost of building out the space. It’s commonly expressed as a dollar figure per square foot of leased area, and it can cover a meaningful portion of construction costs, particularly for a larger retail or office buildout.

How and when that money actually gets paid varies significantly from lease to lease. Some landlords pay the allowance only after the buildout is substantially complete and inspected, while others release it in stages tied to specific construction milestones. Some leases require the tenant to submit paid invoices or lien releases before funds are advanced. None of this is standardized, which makes reading the payment mechanism closely — rather than assuming the allowance works a particular way — an important step before relying on it to finance a buildout.

It’s also worth confirming what happens if the tenant doesn’t use the full allowance, or if the lease ends early before the full term that the allowance was tied to. Some leases require a prorated repayment of the allowance if the tenant leaves early, treating it functionally like a loan rather than a true grant — a detail that’s easy to miss during the excitement of negotiating a new location.

It’s also common for a landlord to amortize the allowance into the rent itself rather than paying it as a lump sum — effectively rolling the cost of the buildout contribution into a slightly higher rent over the term. Understanding whether an allowance is a direct payment or a rent-amortized contribution changes how it should be factored into a tenant’s overall cost comparison between different spaces being considered.

Ownership of leasehold improvements is a matter of lease wording, not a fixed legal default. During the lease term, some leases treat improvements as the tenant’s property, while many others specify that anything affixed to the premises becomes part of the real property — and therefore the landlord’s — immediately upon installation, regardless of who paid for it. This can come as a surprise to a tenant who assumes that because they paid for the buildout, they also own it outright.

At the end of the lease, the picture can shift again. A lease might provide that improvements automatically become the landlord’s property at expiry (common where the landlord contributed a significant allowance), or it might require the tenant to remove some or all of them — which leads directly into the make-good question below. A lease that doesn’t clearly address ownership at both of these stages — during the term and at its end — leaves an ambiguity that’s far better resolved in the drafting stage than argued over once the tenant is moving out.

A make-good clause, also called a restoration clause, requires the tenant to remove some or all of its leasehold improvements at the end of the lease and return the unit to a specified condition — frequently described as “base building” condition, or the condition the space was in before the tenant’s buildout. Depending on the scope of the original improvements, satisfying a make-good obligation can involve real demolition, patching, and restoration costs, sometimes running into tens of thousands of dollars for a heavily customized space like a restaurant or medical clinic.

The scope of a make-good clause deserves careful attention. A well-drafted version lists specifically what must be removed and what can stay, and describes the condition the space needs to be returned to in concrete terms. A vaguely worded clause — one that simply says the tenant must restore the premises to their “original condition” without further detail — invites disagreement at exactly the point when the tenant has the least leverage: while trying to hand back keys and close out the tenancy.

It’s also a clause that’s often genuinely negotiable before signing. A tenant can reasonably ask to exclude standard finishes from the make-good requirement, cap the scope to specific items like a kitchen hood or a walk-in cooler, or remove the obligation entirely in exchange for other concessions. Raising this during lease negotiations, when both sides still have something to trade, is far more effective than trying to renegotiate it once the move-out date is approaching.

Leasehold improvements generally receive their own treatment under Canadian tax rules, distinct from ordinary repair and maintenance expenses. Rather than being deducted all at once in the year the cost is incurred, improvement costs are often capitalized and deducted gradually over a period of years, reflecting the fact that the improvement provides value to the business over more than a single tax year.

The exact treatment depends on the nature of the specific expense and the business’s individual circumstances, and it can also interact with how any landlord-provided tenant allowance is treated. This article describes the general shape of the issue only — it is not tax advice, and a tenant planning a significant buildout should speak with an accountant familiar with their specific situation before relying on any particular tax treatment.

Because so much of this area depends on the specific wording of the lease rather than a default rule, the most practical step a tenant can take is making sure the allowance amount and payment schedule, ownership of improvements during and after the term, and any make-good obligations are all addressed clearly — either directly in the lease or in a clearly referenced work letter attached to it. A verbal understanding, or an informal side agreement that isn’t incorporated into the lease, is considerably harder to rely on if a disagreement surfaces later.

Where a disagreement does arise — for example, over whether a particular fixture needed to be removed, or whether an allowance was properly earned — our guide on commercial lease disputes in Ontario covers how these disagreements are generally approached.
