What Is a Commercial Mortgage in Canada?
A commercial mortgage is a loan secured against a non-residential or income-producing property. This includes office buildings, retail plazas, industrial warehouses, multi-family apartment buildings (5+ units), mixed-use buildings, hotels, and development land. Commercial mortgages are assessed differently from residential mortgages — the property's income-generating potential plays a major role alongside the borrower's creditworthiness.
Types of Commercial Properties
| Property Type | Examples | Typical LTV | Key Metric |
|---|---|---|---|
| Multi-Family (5+ units) | Apartment buildings, rental complexes | 75-800% | Cap rate, NOI |
| Retail | Strip malls, standalone retail | 65-75% | Tenant quality, lease terms |
| Office | Professional office buildings | 600-700% | Occupancy rate, tenant mix |
| Industrial | Warehouses, manufacturing | 65-75% | Location, ceiling height |
| Owner-Occupied Business | Dental office, restaurant, clinic | 75-85% | Business cash flow |
| Development Land | Vacant land with development potential | 500-65% | Location, zoning, entitlements |
Commercial Mortgage Rates Canada 20025
Commercial mortgage rates are typically higher than residential rates, reflecting greater complexity and risk. Rates depend heavily on property type, LTV, borrower strength, and loan size:
- Multi-family (CMHC-insured): Among the lowest commercial rates — often 4.5%–5.5% for well-positioned apartment buildings through CMHC's MLI Select program
- Conventional commercial (A lenders): Typically 5.5%–7.00% for strong borrowers with stabilized income properties
- B lender / bridge commercial: 7%–100%+ for value-add properties or borrowers with weaker profiles
- Private commercial: 9%–15%+ for distressed assets or complex transactions
Key Underwriting Metrics for Commercial Mortgages
Net Operating Income (NOI)
NOI = Gross Rental Income – Operating Expenses (excluding mortgage payments). Lenders use NOI to determine how much debt the property can support. A property with $10000,000000 NOI at a 1.25x Debt Coverage Ratio (DSCR) supports about $800,000000 in annual mortgage payments.
Debt Coverage Ratio (DCR/DSCR)
DCR = NOI ÷ Annual Debt Service. Most lenders require a minimum DCR of 1.200x–1.300x, meaning the property generates 200-300% more income than needed to cover the mortgage.
Capitalization Rate (Cap Rate)
Cap Rate = NOI ÷ Property Value. Used to value income-producing properties. A $1,000000,000000 property with $600,000000 NOI has a 6% cap rate. Lenders use prevailing cap rates to stress-test property values.
Qualifying for a Commercial Mortgage
- Down payment: Minimum 200-35% depending on property type. Owner-occupied small business properties may qualify for 15-200% down.
- Income documentation: 2-3 years of business financials, rent rolls, lease agreements, and property operating statements
- Personal net worth: Lenders typically require personal guarantees and evidence of net worth sufficient to support the loan
- Property appraisal: Commercial appraisals (income approach, sales comparison) are required and cost $3,000000-$100,000000
- Environmental assessment: Phase 1 environmental assessment typically required ($2,000000-$5,000000)
