Key factors for evaluating this commercial property
Commercial Due Diligence Checklist
· Verify zoning and all permitted uses
· Review all existing leases (terms, renewals, net vs. gross)
· Request estoppel certificates from all tenants
· Order a Phase 1 Environmental Site Assessment
· Commission a property condition assessment
· Review operating costs (taxes, insurance, maintenance)
Commercial Financing Note
Commercial mortgages require 20–35% down, shorter amortization, and lenders underwrite based on the property's income. CMHC insurance is not available for commercial. Connect with a commercial mortgage broker early.
Commercial and land transactions are significantly more complex than residential. Joe recommends assembling a team — commercial real estate lawyer, accountant, and (for land) a land use planner — before making an offer.

Joe's Thoughts
Honest perspective from 30+ years of GTA real estate experience
Commercial Pricing Context
Commercial property values in Downsview are driven by location, zoning, current tenancy, and income potential — not the same $/sqft benchmarks as residential. I'll run a proper comparable sales analysis using recent commercial transactions in this area.
Extended Exposure — Negotiating Room
At 180 days on market, this commercial property has had significant exposure. Commercial listings typically take longer to sell than residential, but this timeline may indicate pricing or tenancy issues worth exploring. A motivated seller often means better terms for a prepared buyer.
Zoning & Permitted Use — Verify First
I always confirm the zoning and permitted uses before a client gets too far into a commercial transaction. What a property is currently used for and what it's legally permitted for are sometimes different. If you plan to change the use, a zoning amendment or minor variance may be required — that's additional cost, time, and risk.
Tenancy & Income Review
If this property has existing tenants, I'd want to review all leases carefully: term lengths, renewal options, rent amounts, escalation clauses, and who's responsible for operating costs (gross lease vs. net lease). A strong long-term tenant is an asset; a lease expiring at closing is a different story. We'll request estoppel certificates from all tenants.
Environmental & Due Diligence
A Phase 1 Environmental Site Assessment is standard practice for commercial purchases in Ontario. If historical industrial use is flagged, you'll need a Phase 2. I also recommend a property condition assessment covering structure, roof, HVAC, and electrical — commercial systems are expensive to replace and often not disclosed in detail on the listing.
Commercial Financing Realities
Commercial mortgages work differently than residential. Expect 20–35% down, shorter amortization (15–25 years), and lenders who underwrite based on the property's income, not just your personal financials. CMHC insurance is generally not available for commercial, and rates are typically higher. I can connect you with commercial mortgage brokers who specialize in Downsview transactions.
