Buying commercial real estate in Canada is a different discipline from residential — financing is more conservative, due diligence is broader (environmental, leases, zoning), and tax structuring matters from day one. Whether you are buying a Scarborough multi-family, a small office condo, or an industrial flex space in Mississauga, the steps below outline the standard Canadian playbook.
In this guide, we cross-reference How to Buy a House in Ontario, Fair Market Value, and Capital Gains Tax — click through whenever you want to go deeper on a related concept.
Step 1 — Define the Investment Thesis
What is the goal? Owner-occupancy, cash flow, value-add, or land banking? The thesis drives property type, location, and structure.
Step 2 — Build Your Team
- Commercial real estate broker (RECO-licensed in Ontario).
- CPA familiar with Canadian real estate taxation.
- Commercial real estate lawyer.
- Mortgage broker or commercial banker.
- Environmental consultant.
Step 3 — Pre-Qualify Your Financing
Commercial financing in Canada typically requires 25–40% equity. Underwriting focuses on Debt Service Coverage Ratio (DSCR — usually 1.20–1.30x minimum) and the asset's net operating income (NOI). CMHC MLI Select offers favourable terms for purpose-built rental.
Step 4 — Source and Underwrite Properties
Use TRREB Commercial, ICX.ca, your broker's network, and direct outreach to owners. Underwrite each candidate on a pro-forma cap rate, NOI, and 10-year cash-on-cash return.
Step 5 — Letter of Intent (LOI)
Most commercial deals start with a non-binding LOI: price, due diligence period, deposit, key terms. The LOI funnels into the binding Agreement of Purchase and Sale.
Step 6 — Due Diligence Period (60–120 Days)
- Phase I (and possibly Phase II) environmental site assessment.
- Building condition assessment.
- Title search and survey review.
- Lease abstracts for every tenant — rent, term, renewal, escalation.
- Estoppel certificates from major tenants.
- Zoning and permitted-use confirmation.
Step 7 — Final Financing and Closing
Submit the appraisal, environmental, and rent roll to your lender for final commitment. Your real estate lawyer prepares the Statement of Adjustments, registers the transfer, and addresses HST on commercial transactions (often payable but recoverable as an input tax credit if you are HST-registered).
Step 8 — Post-Closing Asset Management
Engage a property manager (or self-manage), implement your value-add plan, and review insurance coverage. Track CCA (Capital Cost Allowance) for tax purposes with your CPA.
Frequently Asked Questions
How much do I need to put down on Canadian commercial real estate?+
Conventional commercial financing requires 25–40% equity. CMHC-insured purpose-built rental can go to 5–15% in some cases under MLI Select with strong borrower covenants.
Is HST charged on commercial real estate purchases?+
Yes — HST applies to most commercial real estate transactions in Ontario. If you are HST-registered, you typically claim an input tax credit. Confirm with your CPA before closing.
How long is a typical due diligence period?+
60–120 days is standard, depending on complexity. Environmental Phase II investigations alone can take 30–60 days, so plan accordingly in your APS.
What is a Phase I ESA?+
A Phase I Environmental Site Assessment is a non-intrusive review of historical site use and current conditions to identify potential contamination concerns. If concerns are found, a Phase II ESA (with soil and groundwater sampling) is typically commissioned.
