Commercial Mortgages in Ontario: What Investors Need to Know in 2026

Commercial mortgage financing in Ontario operates on a completely different set of rules than residential lending. The underwriting criteria, the rate structures, the approval process, and even the relationship with lenders — all of it changes when you move from houses and condos to multi-family buildings, retail plazas, and mixed-use properties.

If you're an investor looking to finance your first commercial property, or an experienced residential investor ready to scale into commercial, this guide will give you the foundational knowledge you need. We'll cover how commercial lenders think, what they look for in 2026, and how to position yourself for approval.

Commercial vs Residential: The Real Differences

In residential lending, the underwriting process focuses primarily on you — your income, your credit score, your debt ratios. The property matters, but the lender's fundamental question is: "Can this borrower make the payments?"

In commercial lending, that question flips. The lender's fundamental question becomes: "Can this property make the payments?" Your personal financials still matter, but they're secondary to the property's ability to generate income and service debt.

This shift has major implications:

• Property income documentation is critical. Lenders will scrutinize rent rolls, lease agreements, operating statements, and vacancy history far more than your personal T4s.
• Appraisals are more complex. Commercial appraisals use income-based valuation methods (capitalization rate, discounted cash flow) rather than simple comparable sales.
• Loan-to-value limits are lower. While residential mortgages can go up to 95% LTV with CMHC insurance, commercial typically caps at 75% LTV — sometimes lower for certain property types.
• Terms are shorter. Five-year terms are common in residential; in commercial, 1-3 year terms with renewal negotiations are more typical.
• Rates aren't published. There's no rate board for commercial mortgages. Every deal is priced individually based on property type, location, borrower strength, and lender appetite.

Commercial lenders don't underwrite the borrower the same way residential lenders do. They underwrite the property — and whether it'll still cash flow in three years.

Property Types & Lender Appetites in 2026

Not all commercial properties are created equal in lenders' eyes. In 2026, here's where different property types stand:

Multi-family residential (5+ units) — This is the most favored commercial property type. Lenders love the stable cash flow, low vacancy risk, and essential nature of housing. Expect the best rates and highest LTVs here. CMHC MLI Select provides insured financing up to 95% LTV for qualifying multi-family properties.

Industrial / warehouse — Strong lender appetite, especially for well-located properties with long-term tenants. The e-commerce boom continues to drive demand for distribution and logistics space.

Retail (strip plaza, standalone) — Cautious lender appetite. The post-pandemic retail landscape remains uncertain. Lenders want to see essential tenants (grocery, pharmacy, medical) and long lease terms. Pure discretionary retail is harder to finance.

Office — Challenging in 2026. Work-from-home trends have permanently altered office demand. Suburban office and medical office are easier to finance than downtown high-rise. Expect lower LTVs and higher rates.

Mixed-use (retail + residential) — Depends heavily on the mix. Properties where residential is 60%+ of the income are treated more favorably than retail-heavy mixed-use.

Development land — Very limited lender appetite for raw land. Lenders generally want to see zoning approvals, site plan approval, and often pre-sales before financing development.

The DSCR Threshold (and Why It Matters)

DSCR — Debt Service Coverage Ratio — is the single most important metric in commercial mortgage underwriting. It measures whether the property generates enough income to cover the mortgage payments.

The calculation is simple:

DSCR = Net Operating Income / Annual Debt Service

For example, if a property generates $180,000 in NOI (rental income minus operating expenses, before mortgage payments) and the annual mortgage payments would be $150,000, the DSCR is 1.20.

Most institutional lenders require a minimum DSCR of 1.20 to 1.25. This means the property must generate 20-25% more income than needed to service the debt. The buffer protects the lender against vacancy, rent decreases, or unexpected expenses.

Here's a practical example:

• Purchase price: $2,000,000
• Gross rental income: $240,000/year
• Operating expenses (taxes, insurance, maintenance, management): $60,000/year
• Net Operating Income: $180,000
• Requested mortgage: $1,400,000 (70% LTV)
• At 6.5% over 25 years, annual debt service: $113,400
• DSCR: $180,000 / $113,400 = 1.59

A 1.59 DSCR is excellent and would qualify easily at most lenders. If the same property only generated $140,000 NOI, the DSCR would drop to 1.23 — still acceptable but with less margin for error.

Multi-Family: The Sweet Spot Right Now

If you're looking for the most favorable commercial financing terms in Ontario right now, multi-family residential (5+ units) is where to focus. Here's why:

CMHC MLI Select. For qualifying multi-family properties, CMHC offers insured financing with LTVs up to 95%, amortizations up to 50 years, and rates 0.50-1.00% below conventional commercial rates. The catch: you need to meet energy efficiency or affordability requirements, and the process is more documentation-heavy.

Stable cash flow. Housing is an essential need. Multi-family buildings in Ontario have vacancy rates under 2% in most markets. Lenders recognize this stability and price it into their risk assessments.

Favorable cap rate compression. Investor demand for multi-family has compressed cap rates, driving property values higher. This benefits existing owners and makes equity growth predictable.

The transition from 4 units (residential) to 5+ units (commercial) is where many investors get stuck. The financing rules change completely, and a property that qualified easily at 4 units may face additional scrutiny at 5. We help investors navigate this transition regularly.

Mixed-Use & Storefront: Where Lenders Are Cautious

Mixed-use properties — typically retail on the ground floor with residential above — present unique challenges:

Income allocation matters. If 70% of the income comes from stable residential tenants and 30% from retail, lenders are more comfortable. If the split is reversed, expect more scrutiny and potentially lower LTV offers.

Retail tenant quality is examined closely. A 10-year lease with a national tenant is viewed very differently than a month-to-month lease with a new restaurant. Lenders will analyze lease terms, tenant financials (sometimes), and renewal probability.

Location within the building matters. Corner retail with good visibility and parking is valued more than retail tucked into a basement or rear entrance.

For pure storefronts (retail-only buildings), the challenge intensifies. Unless you have long-term leases with creditworthy tenants, expect to work with B lenders or private commercial lenders at higher rates.

How Rates Are Built (And Why You Won't See Them Online)

Unlike residential mortgages, where you can find current rates on any bank's website, commercial mortgage rates are priced deal-by-deal. Here's what goes into the calculation:

• Base rate: Usually tied to Government of Canada bond yields or the lender's cost of funds
• Credit spread: An addition based on the property's risk profile, typically 1.5% - 4%+
• Property type premium: Multi-family gets the best spread; retail and office get wider spreads
• Term premium: Longer terms (5+ years) typically carry higher rates than 1-3 year terms
• Borrower strength adjustment: Strong personal guarantors with net worth and experience can negotiate better spreads

In early 2026, rough rate ranges look like this:

• CMHC-insured multi-family: 4.75% - 5.50%
• Conventional multi-family: 5.50% - 6.75%
• Industrial: 6.00% - 7.50%
• Retail (strong tenants): 6.50% - 8.00%
• Mixed-use: 6.25% - 8.50%
• Private commercial: 8% - 14%+

These ranges shift constantly based on bond markets, lender competition, and economic sentiment. The only way to get an accurate quote is to submit a deal for review.

The Application Package: What You Need

Commercial mortgage applications require significantly more documentation than residential. A complete package typically includes:

Property documents:

• Purchase agreement (if acquisition)
• Current rent roll showing all units, tenants, lease terms, and rents
• Copies of all lease agreements
• Two years of operating statements (income and expenses)
• Property tax bills
• Insurance certificate
• Environmental reports (Phase 1, sometimes Phase 2)
• Building condition report (for larger properties)
• Survey and title documents

Borrower documents:

• Personal net worth statement
• Two years of personal tax returns (T1 Generals)
• Two years of Notices of Assessment
• Corporate documents if borrowing through a corporation
• Schedule of real estate owned (all properties you own)
• Resume/CV highlighting real estate experience

Missing or incomplete documentation is the number one cause of delays in commercial financing. We provide clients with a detailed checklist upfront to avoid back-and-forth during underwriting.

Strategy for Portfolio Investors

If you're building a commercial real estate portfolio in Ontario, here are strategic considerations:

Start with multi-family. The most favorable financing terms, the most stable cash flow, and the easiest path to building a track record. Once you have 2-3 successful multi-family deals, lenders view you as experienced and offer better terms on subsequent purchases.

Build relationships, not just transactions. Commercial lending is relationship-driven. A lender who knows your track record and trusts your judgment will move faster, offer better terms, and work with you through challenges. We introduce clients to lenders strategically, building those relationships over time.

Understand the refinance path.Many commercial deals that don't work at acquisition become excellent refinance candidates 2-3 years later after you've increased rents, reduced vacancy, and improved NOI. Structure your initial financing with the refinance in mind.

Keep personal guarantees in perspective. Almost all commercial mortgages require personal guarantees from the principals. This means your personal assets are at risk if the property fails. Structure deals conservatively enough that you can weather downturns without personal financial catastrophe.
