04What moves the number
Cost drivers for this type in Ottawa
Site work share
surface parking, curbs and landscaping frequently exceed 15 percent of hard cost on a plaza.
Demising and metering
more units means more party walls, more services and more meters per square foot.
Storefront glazing linear footage, not area, drives the envelope cost.
Storefront glazing linear footage, not area, drives the envelope cost.
Restaurant-capable bays need grease exhaust and heavier services designed in from day one.
Restaurant-capable bays need grease exhaust and heavier services designed in from day one.
Federal tenant fit-outs set the quality benchmark in Ottawa, pulling office TI budgets above the provincial average. That is why the same drawings priced in Ottawa 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 $6,287,200 and everything after it — soft cost, charges, contingency and escalation — adds $1,897,477. 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 retail strip in Ottawa?
On the curated Ottawa band, hard cost runs $219 to $342 per square foot for a retail strip at standard specification. Adding site work, soft cost, charges, contingency and twelve months of escalation puts the all-in figure near $409 per square foot on a 20,000 sf preset. Your own area and specification change that number, which is what the builder above is for.
Why does Ottawa price where it does?
Federal tenant fit-outs set the quality benchmark in Ottawa, pulling office TI budgets above the provincial average. The published Toronto base range is scaled by a documented factor of 0.95 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 Ottawa 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.
