Building specifications
Building class
A / B / C
Determines finishes, systems quality, amenities and tenant demand. Class A vacancy is 7.6% — extremely tight.
2,000 – 40,000 sq ft
Larger floor plates allow open-plan layouts. Small plates (under 5,000 sq ft) suit boutique firms. Efficiency ratio (usable vs gross) should exceed 80%.
8 ft – 14 ft+
Modern Class A builds offer 10–14 ft finished ceilings. Under 8 ft feels dated and limits HVAC retrofits.
Central / fan coil / VAV
Age and type of HVAC is the largest operating cost driver. Check for asbestos in buildings pre-1990.
4–8 watts/sq ft typical
Tech and medical users may require 8–12+ watts per sq ft. Confirm available power capacity before any offer.
Required 3+ storeys
Number of cabs, wait times, and modernisation status affect occupier satisfaction and building value.
LEED Gold / BOMA BEST
ESG credentials increasingly required by corporate tenants and institutional buyers. Check certification status and expiry.
Location & operational factors
Parking ratio
1:200 – 1:1,000 sq ft
Suburban offices require 1 stall per 200–300 sq ft for typical business use. Downtown buildings rely on transit access instead.
Transit access
PATH / TTC / GO / BRT
Downtown buildings: PATH or TTC subway access drives premium pricing. Suburban: highway proximity and GO station proximity are key.
Zoning
Commercial / Mixed-Use
Confirm permitted uses — especially for medical, retail at grade, or future residential conversion potential. CR and CRE zoning in Toronto supports the broadest range of uses.
Building size (GFA)
5,000 – 500,000+ sq ft
Total gross floor area determines financing, operating cost exposure, and management intensity. Single-floor occupancy simplifies operations for owner-users.
Year built & condition
Roof, windows, lobby
Buildings over 30 years old often require window replacements ($2–5M+), elevator modernisation, and lobby renovation. Budget for capital expenditure before offer.
Residential / Medical / Mixed
Floor-to-floor height (min 9 ft for residential conversion), window depth, and core placement determine feasibility. B/C class buildings near residential zones have the strongest conversion case.
Lobby, gym, café, conf.
Post-pandemic, tenants and buyers expect lobbies, conference centres, and wellness amenities. Absence of these in Class A buildings drives vacancy.

How it works
How BREG guides your
office acquisition
Why own your office instead of leasing?
Fixed occupancy cost
Replace unpredictable escalating lease payments with a fixed mortgage. Average GTA office net rents rose to $22.23 PSF in Q4 2025.
Brand & culture signal
Owning your office space makes a statement to clients, employees, and partners that no lease can replicate.
Capital appreciation
Trophy and Class A office assets in the GTA have retained strong value. The current correction in Class B/C creates a buying opportunity below replacement cost.
Full operational control
Fit out, renovate, and brand your space without landlord approval, lease restrictions, or relocation risk.

Frequently asked questions
Common questions from
office building buyers
What is the price per square foot for office buildings in Toronto?
GTA office buildings sell for approximately $78–$500+ per square foot, depending on class, location, occupancy, and condition. Trophy/Class A assets in prime downtown locations command $300–$500+ PSF. Suburban Class B buildings trade around $250–$350 PSF. Distressed Class C buildings have sold for as low as $78 PSF — creating compelling conversion opportunities. BREG provides current comparable pricing for every submarket.
What is the difference between Class A, B, and C office buildings?
Class A buildings are modern, high-quality, well-located, and amenity-rich — vacancy is just 7.6% in Toronto. Class B buildings are older but well-maintained functional spaces with solid occupancy — the best value segment for owner-users. Class C buildings are dated assets struggling with demand, but performing well for medical use and presenting the strongest conversion-to-residential potential. BREG recommends the right class for your specific objectives.
Is now a good time to buy an office building in Toronto?
Yes — for owner-users and strategic buyers, 2025–2026 represents a defined acquisition window. Downtown Toronto office vacancy peaked in 2024 at 14.8% and is now declining to 13.0%. Prices on Class B and C assets are below replacement cost. Suburban office buildings with long-term leases are trading at 7% cap rates. Annual downtown absorption in 2025 was the strongest since 2017. BREG monitors these signals weekly to advise buyers on timing.
What financing is available for buying an office building in Ontario?
Office buildings are financed as commercial real estate — typically 60–70% LTV through conventional commercial mortgages based on property value and the buyer's business strength. Owner-occupying businesses may access additional financing through BDC (Business Development Bank of Canada) or government-backed programs. CMHC does not insure office properties. BREG connects buyers with commercial mortgage specialists experienced in GTA office acquisitions.
Can a Class B or C office building be converted to residential in Toronto?
Yes — Toronto's Office Conversion Pilot Program and various incentives encourage the adaptive reuse of underperforming office buildings. Key feasibility factors include floor-to-floor height (minimum 9 ft for residential), window depth, building core placement, and site zoning. Class C buildings near residential zones with CR or mixed-use zoning have the strongest conversion case. BREG assesses conversion potential as part of every Class B/C acquisition analysis.
What due diligence is required when buying an office building?
Key due diligence for a GTA office building includes: Building Condition Assessment (BCA) covering roof, HVAC, elevators, windows, and electrical; Phase 1 Environmental Site Assessment; review of all existing leases and operating cost obligations; zoning confirmation for intended use; and title search. For older buildings, check for asbestos (pre-1990 construction) and lead paint. BREG coordinates all due diligence streams and identifies issues before they become costly commitments.
