Commercial real estate is one of the most powerful wealth-building tools available to Calgary investors and business owners. Whether you are buying a strip mall, acquiring an apartment building with five or more units, or financing an industrial unit for your business, commercial mortgages operate under fundamentally different rules than residential financing.
The lender evaluation criteria are different. The down payment requirements are different. The interest rates, terms, and amortization structures are different. And unlike residential mortgages — where qualifying largely comes down to your personal income — commercial mortgage approval is driven by the income-generating capacity of the property itself.
This guide covers everything you need to know to finance commercial property in Calgary: what qualifies, how lenders underwrite deals, what CMHC MLI Select offers for multi-unit properties, and why Alberta remains one of the most attractive provinces in Canada for commercial real estate investment.
What Qualifies as a Commercial Property
In Canada, the residential-to-commercial threshold is five units. Properties with four units or fewer are classified as residential and financed through residential mortgage programs. Once you cross into five units or more, or when a property includes commercial tenants, you are in commercial mortgage territory.
Property Types That Require Commercial Financing
Multi-unit residential (5+ units): Apartment buildings, purpose-built rental buildings, and any residential complex with five or more self-contained units. This is the most common commercial mortgage category for individual investors.
Retail: Strip malls, standalone retail buildings, power centres, and mixed-use buildings with ground-floor retail tenants. Retail financing depends heavily on tenant quality and lease terms.
Office: Office buildings and strata office units, from small professional office condos to multi-storey towers. Post-pandemic, lenders scrutinize office vacancies carefully — downtown Calgary office vacancy is something lenders factor into their underwriting.
Industrial: Warehouses, distribution centres, light manufacturing facilities, and flex-industrial properties. Industrial is currently one of the strongest commercial asset classes in Calgary, driven by logistics and e-commerce demand.
Mixed-use: Buildings that combine residential and commercial uses — apartments above retail, for example. These are common in inner-city Calgary neighbourhoods and require commercial financing when five or more residential units are involved.
Land and development: Vacant commercial land or properties requiring significant redevelopment. These carry the highest risk and require specialized lenders.
How Commercial Mortgages Differ from Residential
Understanding the differences helps you plan your capital and set realistic expectations before approaching lenders.
Down Payment Requirements
Residential mortgages allow as little as 5% down (with mortgage insurance) for owner-occupied properties. Commercial mortgages require substantially more equity from day one.
Standard commercial down payments:
- Conventional commercial: 25% to 35% of purchase price
- CMHC-insured multi-unit (MLI Select): As low as 15%
- Private lenders: 25% to 40%, depending on property quality and borrower profile
On a $3,000,000 apartment building, that means a minimum of $450,000 to $1,050,000 in down payment depending on the program. This is why access to equity — through savings, existing property equity, or equity partners — is essential for commercial real estate.
Interest Rates and Terms
Commercial mortgage rates are set differently than residential rates. Instead of being primarily tied to the Bank of Canada overnight rate, commercial rates are based on Government of Canada bond yields (typically 5-year bonds) plus a lender spread.
Typical commercial rates (early 2026):
- Conventional commercial: 5.5% to 7.5% depending on asset class, LTV, and lender type
- CMHC-insured multi-unit: 4.8% to 6.0% (insurance reduces lender risk, which reduces rate)
- Private commercial: 8% to 12%+
Commercial terms are typically 5 to 10 years, with amortizations of 20 to 30 years for conventional financing. CMHC MLI Select allows amortizations up to 40 or 50 years for energy-efficient or affordable housing properties — a significant cash flow advantage.
Qualification: Property Income vs Personal Income
This is the most fundamental difference. Residential mortgages qualify you primarily on your personal income — your T4s, NOAs, and employment history. Commercial mortgages primarily qualify the property.
Lenders analyze whether the property generates enough net income to service the debt. Your personal income matters (and is still evaluated), but it is secondary to the property's financial performance. This means a self-employed borrower who writes off significant income on their taxes can still access commercial financing if the property's numbers work — something that is harder to achieve in residential lending.
Stress Test Differences
The federal mortgage stress test (qualifying at the contract rate plus 2%, or 5.25%, whichever is higher) applies to residential insured mortgages. Commercial mortgages use Debt Coverage Ratio (DCR) stress testing instead — lenders require the property's income to cover the mortgage payment by a specified margin, typically 1.1x to 1.25x the annual debt service.
Down Payment Requirements for Commercial Properties
The capital stack for commercial acquisitions is more complex than residential purchases. Understanding which program applies to your property dramatically affects how much equity you need to bring.
Conventional Commercial (No Insurance)
Most commercial properties are financed conventionally, meaning without government-backed mortgage insurance. This requires:
- 25% to 30% down for stabilized income-producing properties (apartment buildings, retail with strong tenants)
- 30% to 35% down for properties with higher risk profiles (office buildings, mixed-use, properties with vacancies)
- Maximum LTV of 65% to 75%, depending on lender and asset class
Conventional commercial lenders include major banks (RBC, TD, BMO, Scotiabank), Alberta-based institutions like ATB Financial and Servus Credit Union, credit unions, and institutional mortgage investment corporations (MICs).
CMHC MLI Select (Multi-Unit Residential)
For multi-unit residential properties of five or more units, CMHC's MLI Select program is transformative. It allows:
- Down payments as low as 15% (85% LTV)
- Amortizations up to 40 years (standard) or 50 years (for projects meeting energy efficiency or affordability thresholds)
- Lower interest rates because CMHC insurance eliminates lender credit risk
The trade-off is the CMHC insurance premium — typically 2.75% to 4.0% of the mortgage amount, added to the principal. For large multi-unit deals, this premium is often worth it given the improved cash flow from extended amortizations and lower rates.
Private Commercial Lenders
When a property does not fit conventional or CMHC criteria — due to vacancies, borrower credit issues, complex ownership structures, or development risk — private lenders fill the gap. Private commercial financing:
- Typically requires 25% to 40% down
- Carries rates of 8% to 12%+
- Has terms of 1 to 2 years (designed as bridge financing, not long-term debt)
- Closes faster than conventional lenders (often 2 to 4 weeks)
Private financing is a bridge, not a destination. The goal is to stabilize the property (fill vacancies, complete renovations, establish operating history) and then refinance to conventional or CMHC financing.
CMHC MLI Select: A Game Changer for Multi-Unit Properties
If you are acquiring or refinancing a multi-unit residential building of five or more units in Calgary, CMHC MLI Select is the most important financing program you need to understand.
What MLI Select Is
MLI Select is CMHC's multi-unit residential insurance program for purpose-built rental, co-operative housing, and social housing projects. It replaced the older CMHC multi-unit program with a points-based scoring system that rewards developers and investors who build or acquire properties that serve affordability, energy efficiency, or accessibility goals.
How the Points System Works
Borrowers accumulate points across three categories: affordability (units rented at below-market rates), energy efficiency (building meets certain EnerGuide or Step Code ratings), and accessibility (units designed for persons with disabilities). Higher point totals unlock better financing terms.
What scoring unlocks:
- Standard MLI Select: 85% LTV, 40-year amortization, standard premium
- MLI Select with affordability/energy/accessibility criteria: Up to 85% LTV, 50-year amortization, and reduced insurance premiums
The 50-year amortization is the real prize. On a $5,000,000 mortgage at 5.5%, the difference between a 25-year and 50-year amortization is roughly $12,000 per month in debt service — a massive cash flow improvement that can make the difference between a property that pencils and one that does not.
Who Qualifies for MLI Select
MLI Select is available to Canadian registered businesses (corporations, partnerships, trusts) — not typically to individual borrowers. The property must be:
- Five or more self-contained residential units
- Located in Canada
- Meeting minimum property condition standards
- Subject to a market rent or affordability commitment depending on which scoring criteria apply
The MLI Select process is complex. It involves CMHC approval, detailed financial underwriting, and property inspection. Jay works directly with lenders who specialize in CMHC multi-unit submissions and can guide clients through the application from start to finish.
How Lenders Evaluate Commercial Mortgage Applications
Commercial underwriting is more rigorous than residential. Lenders analyze the property's financial performance, the borrower's track record, and the quality and stability of the real estate asset.
Net Operating Income (NOI)
NOI is the property's total rental income minus all operating expenses (property taxes, insurance, management fees, utilities, maintenance, and vacancy allowance), before mortgage payments.
Example: 12-unit apartment building
- Gross rental income: $18,000/month ($216,000/year)
- Vacancy allowance (5%): -$10,800/year
- Effective gross income: $205,200/year
- Operating expenses (property taxes, insurance, management, maintenance): -$72,000/year
- NOI: $133,200/year
NOI is the starting point for all commercial underwriting.
Debt Coverage Ratio (DCR)
DCR measures how much cushion exists between the property's income and its debt obligations. Lenders require a minimum DCR of 1.1x to 1.25x — meaning the property's NOI must be at least 10% to 25% higher than the annual debt service.
From the example above:
- NOI: $133,200/year
- Annual debt service on $1.8M mortgage at 5.8%, 25-year amortization: $135,000/year
- DCR: $133,200 / $135,000 = 0.99x — this deal does not qualify at conventional financing
To get this deal to work at conventional terms, the borrower either needs a larger down payment (reducing the mortgage), needs to negotiate a lower purchase price, or needs to use CMHC MLI Select to access a longer amortization (which reduces annual debt service and improves DCR).
Cap Rate
The capitalization rate (cap rate) is NOI divided by purchase price. It is the most common metric for comparing commercial real estate values.
Cap rate = NOI / Purchase Price
Using the example above: $133,200 / $2,500,000 = 5.3% cap rate
Lenders use cap rates to assess whether a purchase price is reasonable relative to market. In Calgary (early 2026):
- Multi-unit residential: 4.5% to 5.5%
- Retail (strip malls): 5.5% to 7.0%
- Industrial: 5.0% to 6.5%
- Office: 6.5% to 8.5% (elevated due to vacancy concerns)
Tenant Quality and Lease Terms
For commercial properties (retail, office, industrial), lenders evaluate tenant quality and remaining lease terms carefully. A strip mall anchored by national tenants on long-term leases (10+ years) is dramatically easier to finance than one with month-to-month local tenants. Strong anchor tenants include grocery stores, pharmacies, major fast food franchises, and national service businesses.
Environmental Assessment
Most commercial lenders require a Phase 1 Environmental Site Assessment (ESA) before approving financing. A Phase 1 ESA reviews historical land use and identifies potential contamination risks. If the Phase 1 identifies "Recognized Environmental Conditions," the lender may require a Phase 2 ESA (soil and groundwater testing) — which adds cost and delays. Budget $2,500 to $5,000 for a Phase 1 ESA and factor it into your due diligence timeline.
Commercial Mortgage Rates and Terms in Calgary
Commercial mortgage pricing in Alberta follows bond market movements, but lender appetite and competition vary by asset class.
Rate Structure
Commercial mortgages are priced as: Government of Canada bond yield + lender spread
For a 5-year commercial term, the pricing reference is typically the 5-year GoC bond yield (currently approximately 3.0% to 3.5% in early 2026) plus a spread that reflects property type, LTV, lease strength, and borrower quality.
Approximate spread ranges (above 5-year GoC bonds):
- CMHC-insured multi-unit: 100 to 175 basis points (1.0% to 1.75%)
- Strong conventional multi-unit: 175 to 250 basis points
- Retail with national tenants: 200 to 275 basis points
- Industrial: 175 to 250 basis points
- Office: 250 to 375 basis points
- Private / bridge: 500 to 900 basis points
Typical Term Lengths
- 5-year fixed: Most common for commercial properties; provides rate certainty during the most critical stabilization period
- 7-year and 10-year fixed: Less common but available; borrowers who want maximum certainty in a rate environment they consider favorable
- Variable rate commercial: Available from some lenders; typically Prime minus 0.25% to Prime plus 0.50%
Amortization Options
- 25 years: Standard for most conventional commercial
- 30 years: Available from some lenders for strong multi-unit properties
- 40 years: CMHC MLI Select standard
- 50 years: CMHC MLI Select with energy/affordability criteria
The longer the amortization, the lower the monthly payment, and the better the DCR. This is why CMHC MLI Select's 40 to 50-year amortizations are so valuable for making multi-unit investments cash-flow positive.
The Calgary Advantage for Commercial Real Estate
Calgary stands out as a commercial real estate market for several structural reasons that investors in Toronto and Vancouver do not enjoy.
No Provincial Land Transfer Tax
Alberta has no provincial land transfer tax. In Ontario, a buyer purchasing a $3,000,000 commercial property pays approximately $40,000 in provincial land transfer tax (plus municipal LTT in Toronto). In BC, the Property Transfer Tax on a $3,000,000 commercial property is approximately $68,000. Alberta buyers pay nothing — reducing acquisition costs and improving deal economics from day one.
Strong Population Growth
Calgary grew by approximately 2.5% to 3% annually in 2023 and 2024, driven by interprovincial migration (from BC and Ontario primarily) and international immigration. This population growth drives residential rental demand, retail spending, and commercial real estate fundamentals.
Diversifying Economy
Calgary's economy, historically oil-and-gas dependent, has diversified meaningfully. Technology, logistics, financial services, and healthcare are now major employment sectors. This diversification reduces the risk of sharp economic corrections that historically hit Calgary when oil prices declined.
Strong Rental Market
Calgary's residential rental vacancy rate remains below 2% — among the lowest in Canada. Average rents increased 8% to 10% year-over-year in 2024-2025. For multi-unit investors, this rental market strength translates directly into higher NOI and better cap rates relative to acquisition cost.
Industrial Demand
Calgary's position as a major logistics hub — connecting Western Canada and serving as a distribution point for Alberta's resource and agricultural sectors — is driving strong industrial demand. Vacancy in quality Calgary industrial space is under 3%, and rents have increased significantly over the past three years.
Documents You Will Need
Commercial mortgage applications are documentation-intensive. Prepare these materials before approaching lenders.
Borrower / Business Documentation
- T2 corporate tax returns (2 to 3 years, if purchasing through a corporation)
- Personal T1 tax returns and Notices of Assessment (2 to 3 years)
- Corporate financial statements (prepared by an accountant, not internally generated)
- Personal net worth statement
- Existing property schedule (list of all real estate owned, with values, mortgages, and NOI)
Property Financial Documentation
- Current rent roll: List of all tenants, unit types, monthly rents, lease start/end dates, and any rent arrears
- Operating statements: Profit and loss for the property for the past 2 to 3 years (or pro-forma for new acquisitions)
- Property tax bills
- Insurance summary
- Capital improvement history (major repairs and upgrades completed)
Property Physical Documentation
- Phase 1 Environmental Site Assessment (most commercial lenders require this)
- Building inspection report (commercial-grade, not residential)
- Zoning confirmation letter (from City of Calgary, confirming legal permitted use)
- Copies of all leases (for retail, office, or industrial properties)
For Development or Value-Add Properties
- Development permit or planning approval status
- Construction cost estimates (from licensed contractor)
- Pro-forma rent assumptions (with market comparables to support)
- Business plan (for first-time commercial borrowers especially)
Having these documents organized before the lender conversation signals professionalism and accelerates the underwriting process. Jay's clients receive a personalized document checklist tailored to their specific property type and transaction.
Frequently Asked Questions
Can I get a commercial mortgage if I'm self-employed or write off a lot of income on my taxes?
Yes — and this is one area where commercial lending is often more accessible than residential. Because commercial mortgages primarily underwrite the property's income (NOI and DCR), your personal income tax picture is less determinative. As long as the property cash flows at the required DCR and you can demonstrate real business history, many commercial lenders can work with self-employed borrowers who have low stated personal income. T2 corporate returns, financial statements, and a strong property are often more relevant than your personal T1.
What is the minimum property size for a commercial mortgage?
There is no strict minimum, but most institutional commercial lenders have a minimum loan amount of $500,000 to $1,000,000. For smaller commercial deals (strata office units, small retail bays), some credit unions and smaller trust companies will go down to $250,000. Properties below these thresholds may need to be financed through residential programs (if they include residential units) or through private lenders.
How long does commercial mortgage approval take?
Longer than residential. A straightforward multi-unit apartment building with good financials and a standard lender typically takes 4 to 6 weeks from application to approval. More complex properties — those requiring CMHC MLI Select approval, Phase 2 environmental work, or properties with complex lease structures — can take 8 to 16 weeks. For time-sensitive acquisitions, always include sufficient financing condition periods (30 to 45 days is reasonable for commercial).
What is the difference between a commercial mortgage and a business loan?
Commercial mortgages are secured by real property and are used specifically to finance the acquisition or refinancing of real estate. Business loans (term loans, lines of credit) are used for operating capital, equipment, and business expenses. The mortgage uses the property as collateral; a business loan may be secured by business assets, receivables, or unsecured. Commercial mortgages typically have lower rates than business loans because real property is a stable, high-quality form of collateral.
Do I need a corporation to get a commercial mortgage?
No, though many commercial borrowers do purchase through corporations for liability protection and tax planning reasons. Commercial mortgages are available to individuals, partnerships, corporations, trusts, and joint ventures. That said, if you are acquiring a multi-unit building valued over $2 million or a commercial property with significant liability exposure, speak to a tax lawyer or accountant about optimal ownership structure before finalizing the purchase — the structure can affect your future financing options, capital gains treatment, and estate planning.
