The tenant improvement allowance is one of the most negotiable elements of a commercial lease, and one of the most poorly understood. Tenants who do not understand how TI allowances work often sign leases with allowances that will not cover the actual build-out cost, then discover the problem after they are legally committed to the space.
This guide explains how TI allowances work in Ontario, how to negotiate them, and how to structure the process so you know what you are committing to before you sign.
How TI Allowances Are Structured
A tenant improvement allowance is an amount of money the landlord agrees to contribute toward the cost of building out the leased space. It is typically expressed as a dollar amount per square foot, for example, $60 per square foot on a 3,000 sq ft space equals a $180,000 TI.
The allowance is not paid upfront. In most structures, the landlord reimburses the tenant (or pays the contractor directly) upon completion of the work, submission of invoices, and confirmation that the work was permitted and completed to the agreed standard.
If the actual construction cost exceeds the TI allowance, the tenant pays the difference. If the cost comes in under the allowance, the surplus typically reverts to the landlord (some leases allow the tenant to apply surplus against rent).
Market Rates for TI Allowances in the GTA
TI allowance levels vary by market, building class, lease term, and landlord. Current market ranges in the GTA:
| Market / Building Type | Typical TI Allowance Range |
|---|---|
| Downtown Toronto Class A office | $80-$130/sqft |
| Suburban GTA office (Mississauga, Vaughan, Markham) | $50-$90/sqft |
| Industrial units with office component | $30-$60/sqft |
| Retail (second-generation space) | $25-$50/sqft |
| Medical buildings | $40-$80/sqft |
These are market reference points, not maximums. In a tenant-favorable market or for a long-term lease with a creditworthy tenant, landlords will often go higher.
Why the TI Rarely Covers Everything
The most common problem we see: a tenant signs a lease with a $60/sqft TI, then gets construction quotes showing the actual build-out cost is $110/sqft. They are committed to the space and suddenly responsible for a $150,000 gap they did not budget for.
This happens because tenants negotiate the TI before getting construction quotes. The sequence should be the opposite.
The Right Sequence: Quote First, Sign Second
Before signing a commercial lease, get a rough construction estimate for the space. This does not need to be a detailed itemized quote, a preliminary scope review and ballpark estimate from an experienced contractor takes a day or two and costs you nothing.
With a real estimate in hand, you know whether the proposed TI covers the build-out you need. If it does not, you negotiate the TI upward, negotiate a longer rent-free period to cover your construction overrun, or reassess whether the space works financially.
The worst possible position is to sign a lease and then discover the economics of the build-out do not work.
What to Ask for Beyond the Allowance Amount
Extended rent-free period. Rather than increasing the TI allowance, some landlords prefer to offer additional rent-free months. This is economically similar for a tenant who will use the construction period as their rent-free period anyway.
Turnkey delivery option. Some landlords prefer to manage the build-out themselves (turnkey delivery) rather than providing an allowance. This can be advantageous if the landlord has good contractor relationships and the tenant does not have construction management experience. The risk is less control over quality and specification.
TI disbursement terms. Push for milestone-based disbursement rather than completion-only payment. A landlord who holds the full TI until final completion creates cash flow pressure on the tenant, who must fund the full construction cost upfront and wait for reimbursement.
Scope approval process. Confirm the process for getting the landlord's written approval on your construction plans before work starts. Landlords have the right to approve contractor selection and scope. Understanding this process before it is needed prevents delays.
Using Your Contractor to Validate the TI
Once you have a TI number in the lease term sheet, ask your contractor to review it against the space and your intended build-out. A good contractor will tell you directly whether the allowance is realistic, high, or short, and by how much.
VNG regularly reviews TI term sheets for clients who are evaluating spaces before signing. Getting a reality check on whether the economics work takes a site visit and a day or two of scoping, and it has saved more than one client from a difficult situation.
