Buying a office.

FAQ

Office FAQ — what buyers ask

Direct answers about office buying in the GTA. Specific numbers, Ontario regulations, 2026 market data.

• What's the cap rate for office in the GTA in 2026?

  Cap rates for stabilized office buildings in the GTA range 6.0%-7.5% in 2026, up from 5.0%-6.0% pre-pandemic. Downtown Toronto Class A office averages 5.5%-6.5%; suburban office (Markham, Mississauga, Brampton) averages 7.0%-8.5%. Small medical/professional office condos under 5,000 sqft trade at 5.5%-6.0% due to owner-occupier demand.

• Is office space a good investment in Toronto in 2026?

  Cautious yes for the right asset class. Class A downtown office is recovering — major employers are calling employees back 3-5 days. Class B and suburban office remains soft with 12-18% vacancy. Best opportunities: small office condos (under 5,000 sqft) for professional users, and value-add Class B with conversion potential to multi-family or hotel use.

• How is office space leased — what's a typical net rent?

  Most office space is leased on a net rent + additional rent (taxes, maintenance, insurance) basis. Downtown Toronto Class A net rent in 2026 averages $30-40/sqft + $20-30/sqft additional = $55-70/sqft gross. Suburban Class B averages $14-22/sqft net + $14-18/sqft additional = $30-40/sqft gross. Tenant inducements (TIs, free rent) typically equal 6-12 months of base rent.

• What should I review when buying an office building?

  Full rent roll with tenant covenant strength, lease expirations, escalation clauses, and renewal options. Phase II Environmental Site Assessment if prior use was industrial. Property condition assessment (roof, HVAC, parking, life-safety systems). Zoning + permitted use certificate. Major capital reserve schedule — older buildings often need $30-50/sqft capex over 10 years.

• Can office space be converted to residential in Toronto?

  Yes but complex. Toronto has streamlined office-to-residential conversion since 2024 — fast-track approvals available for buildings older than 25 years in select wards. Cost typically $150-250/sqft including HVAC, plumbing risers, and life-safety upgrades. Best candidates: Class B/C office under 200,000 sqft with floor plates under 12,000 sqft. Worst candidates: large floor plates (over 18,000 sqft) which have poor light penetration.

• How do I evaluate a commercial property's cap rate?

  Cap rate = stabilized net operating income (NOI) ÷ purchase price. Calculate NOI by taking gross rental income, subtracting vacancy allowance (5-10%), operating expenses, property tax, and management fee — but NOT mortgage payments. Compare to current market cap for the property class + submarket. A property at 6.5% cap in a 5.5% market is either a deal or has hidden issues — investigate.

• What financing is available for commercial real estate in Canada?

  Standard commercial mortgage requires 30-40% down and amortizes over 20-25 years (vs. 25-30 on residential). Interest rates run 1.0-1.5% above 5-year GIC. CMHC-insured loans available on multi-family 5+ units — down to 15% down with insurance premium added. Vendor takeback (VTB) financing is common on $5M+ deals where the seller carries a second mortgage for 5-10 years.

• What's the typical due diligence process for commercial?

  30-90 day due diligence with conditions. Standard package: Phase I Environmental Site Assessment, property condition assessment (PCA), zoning certificate, rent roll + estoppels, tenant interviews (covenant strength), historical financials (3 years), Tenant + Service contract assignments, lease assignments. For industrial: add Phase II Environmental + soil testing. For multi-family: add LTB filing search. Budget $15-50k in third-party reports.
