Office tenant improvement cost in Toronto
A tenant improvement inside an existing base building: partitions, ceilings, lighting, meeting rooms and a kitchenette. This is the number a tenant compares against the landlord's improvement allowance, so it belongs in the lease negotiation, not after it.

04What moves the number
Cost drivers for this type in Toronto
Density of enclosed rooms
every meeting room adds partition, door, ceiling, HVAC zone and lighting circuit cost.
Base building condition
an as-built ceiling grid, sprinkler layout and HVAC distribution can save or add 15 percent.
Audio-visual, security and data are commonly excluded from a contractor's price and then blow the budget.

Landlord allowance is usually quoted per rentable square foot while the fit-out is priced on usable area.

Toronto is the published base market for Canadian cost guides, and the market where development charges add the most to a non-residential build. That is why the same drawings priced in Toronto and in Toronto do not land at the same number even when the trades are the same.
On the preset build above, hard cost is $1,350,000 and everything after it — soft cost, charges, contingency and escalation — adds $361,584. Budgeting off a hard rate alone is the single most common way an early construction budget goes wrong.

06Questions
What does it cost to build a office fit-out in Toronto?
On the curated Toronto band, hard cost runs $90 to $200 per square foot for a office fit-out at standard specification. Adding site work, soft cost, charges, contingency and twelve months of escalation puts the all-in figure near $171 per square foot on a 10,000 sf preset. Your own area and specification change that number, which is what the builder above is for.
Why does Toronto price where it does?
Toronto is the published base market for Canadian cost guides, and the market where development charges add the most to a non-residential build. The published Toronto base range is scaled by a documented factor of 1.00 for this market, and the ON escalation series is running at 3.2 percent a year.
Is the development charge in this number?
Not by default. We hold a baseline estimate for Toronto but it is not yet verified against the bylaw, so the builder starts it at zero and labels it. Enter your own figure from the municipality.
What is excluded from every figure here?
Land, financing interest during construction beyond the soft-cost allowance, taxes recoverable as input credits, tenant furniture and equipment, and any remediation or off-site works. Those are separate line items in a real proforma.
