Commercial Mortgage Ontario: Complete Financing Guide for Investors

Ontario is Canada’s commercial real estate capital. The GTA alone accounts for more commercial real estate transactions than most entire provinces, and the province’s economic diversity — tech, finance, manufacturing, logistics, government — creates demand across every property class.

But commercial mortgage financing in Ontario comes with its own set of rules, lender expectations, and regulatory considerations that differ meaningfully from residential. Whether you’re acquiring a retail plaza in Mississauga, an industrial building in the Hamilton corridor, or a multi-tenant office in Ottawa, getting the financing right matters as much as finding the right deal.

This guide covers what you need to know about commercial mortgage financing in Canada with a focus on the Ontario market specifically.

Ontario Commercial Real Estate Market Overview

Ontario’s commercial market is the most liquid and lender-active in Canada. That’s good news for borrowers: more lenders competing for deals means better pricing and more financing options.

Market Segment	Key Submarkets	Activity Level
Industrial	GTA West, Hamilton, Kitchener-Waterloo	Very High
Retail	GTA (power centres, plazas)	Moderate
Multi-Family	Toronto, Ottawa, Hamilton	Very High
Office	Downtown Toronto, Ottawa Core	Moderate (post-COVID recovery)
Mixed-Use	Toronto intensification zones	High

The GTA industrial corridor — stretching from Mississauga through Brampton, Vaughan, and out to Halton and Hamilton — is one of the most undersupplied industrial markets in North America. Vacancy rates in prime GTA industrial submarkets consistently run below 2%, driving cap rate compression to historic lows of 4.0–5.0% for class-A assets.

Ottawa presents a different profile: steady government-driven demand, lower price points than Toronto, and consistent multi-family absorption supported by federal public sector employment.

Commercial Mortgage Rates in Ontario

Commercial mortgage rates in Ontario are determined by a combination of the lender’s cost of funds, the property’s risk profile, the borrower’s financial strength, and current market conditions.

Rate Ranges by Property Type (2025–2026)

Property Type	Conventional Rate Range	CMHC-Insured Rate
Multi-family (5+ units)	5.25% – 6.50%	4.75% – 5.50%
Industrial	5.50% – 6.75%	N/A (limited)
Retail	5.75% – 7.25%	N/A
Office	6.00% – 7.50%	N/A
Mixed-Use	5.50% – 6.75%	4.75% – 5.50%*

*Mixed-use with 50%+ residential component may qualify for CMHC insured programs.

Rates above reflect typical bank and institutional lender pricing. Private lenders in Ontario will price higher — typically 8–12% or more — but offer speed and flexibility that institutional lenders cannot.

Fixed vs. Variable for Commercial

Most commercial lenders in Ontario offer 1–5 year fixed terms on commercial mortgages. Variable-rate commercial products exist but are less common than in residential. For income property financing, most sophisticated investors favour 3–5 year fixed terms to lock in a known debt service cost and match it against their lease term structure.

Loan-to-Value and DSCR Requirements

LTV by Property Type

Property Type	Maximum LTV (Conventional)	Maximum LTV (CMHC)
Multi-family (5+ units)	75%	85%
Industrial	65% – 75%	N/A
Retail	60% – 70%	N/A
Office	55% – 65%	N/A
Mixed-Use (50%+ resi)	75%	85%
Land	50% – 60%	N/A

DSCR Minimums

Debt Service Coverage Ratio (DSCR) is the primary underwriting metric for commercial mortgages. Lenders calculate it as Net Operating Income divided by annual debt service.

• Minimum DSCR for most institutional lenders: 1.20x – 1.25x
• Preferred DSCR: 1.30x and above
• CMHC multi-family: 1.10x minimum with full debt service (principal + interest)
• Private lenders: May accept 1.10x or below for strong real estate collateral

For a $2M industrial acquisition at a 5.5% cap rate, that’s $110,000 NOI. If your annual debt service on a $1.4M mortgage (70% LTV) at 6.0% over 25 years is approximately $107,000, you’re right at the 1.03x threshold — too thin for most banks. This is a common challenge in Ontario’s compressed cap rate environment, where strong asset prices have outpaced rental income growth.

Key Ontario Lenders for Commercial Mortgages

Big 5 Banks

RBC, TD, Scotiabank, BMO, and CIBC are all active commercial lenders in Ontario. They offer competitive rates but have strict underwriting requirements and can move slowly on approvals — 45–90 days is typical. Big 5 banks prefer:

• Borrowers with strong balance sheets and net worth
• Properties with stabilized occupancy (90%+ for 12+ months)
• Established track record in commercial real estate
• DSCR well above minimums

Credit Unions

Ontario credit unions — Meridian, Libro, FirstOntario, and others — are often more flexible than chartered banks on underwriting. They hold mortgages on their own balance sheets (rather than securitizing), which gives their underwriters more discretion. Credit unions are particularly active in:

• Rural and secondary market Ontario properties
• Deals that don’t fit standard bank boxes
• Smaller commercial transactions ($500K–$5M) where banks show less appetite

CMHC Multi-Family Programs

The Canada Mortgage and Housing Corporation insures multi-family mortgage financing for apartment buildings with 5+ units. In Ontario, CMHC is the primary tool for maximizing leverage on apartment acquisitions and new construction.

Key CMHC programs relevant to Ontario:

MLI Select — CMHC’s flagship insured program for purpose-built rental. Offers up to 95% LTV on new construction and up to 85% on existing apartments. Achieves rates typically 50–75 basis points below uninsured equivalents. Properties in Ontario’s major markets score highly on CMHC’s MLI Select scoring matrix due to affordability and energy efficiency bonuses.

Affordable Rental Housing — Enhanced LTV for projects committing to below-market rents.

Life Insurance Companies and Pension Funds

For larger commercial transactions ($10M+), life insurance companies (Sun Life, Great-West Life, Manulife) and pension fund real estate arms (CPP Investments, HOOPP, Oxford) are significant capital sources in the Ontario market. They offer long amortization periods, competitive rates, and stable capital — but have high minimum deal sizes and require institutional-quality assets.

Private Lenders and MICs

Ontario has a well-developed private lending market through Mortgage Investment Corporations (MICs) and private mortgage funds. Private capital is essential for:

• Value-add acquisitions where occupancy or income doesn’t yet support conventional underwriting
• Properties with environmental issues requiring remediation before institutional refinancing
• Quick closings (5–15 business days) where speed matters more than rate
• Borrowers rebuilding credit or with non-standard income documentation

Ontario-Specific Regulatory and Tax Considerations

Land Transfer Tax

Ontario levies a provincial land transfer tax (LTT) on all real property purchases. For commercial properties, the rate is:

Purchase Price	Provincial LTT Rate
First $55,000	0.5%
$55,001 – $250,000	1.0%
$250,001 – $400,000	1.5%
Over $400,000	2.0%

Toronto Municipal LTT — City of Toronto buyers pay an additional, identical municipal LTT on top of the provincial rate. Buying a $5M commercial property in Toronto triggers approximately $180,000+ in combined LTT. This is a material acquisition cost that must be factored into financing needs and deal analysis.

Note that LTT is paid at closing and typically cannot be mortgaged — you need this capital as part of your equity contribution plus closing costs budget.

HST on Commercial Real Estate

Unlike residential resale properties, commercial real estate transactions are generally subject to HST in Ontario. If the buyer is an HST registrant (which most commercial real estate investors should be), the HST paid on acquisition can be recovered through HST rebate claims — but there is a timing consideration as the refund typically takes 4–8 weeks post-closing. Plan your cash flow accordingly.

New commercial construction is always HST-applicable. Acquisition of an existing commercial property where the vendor was using it in a commercial activity can be structured as a “going concern” transfer to avoid HST applicability — work with a tax lawyer on this.

Municipal Zoning and Development Charges

Ontario municipalities have significant control over commercial property use through zoning by-laws. Before financing any commercial acquisition:

• Confirm the current permitted use under the applicable zoning by-law
• Identify any legal non-conforming status (grandfathered uses that exist outside current zoning)
• Understand whether your intended use requires a minor variance or rezoning
• Account for Ontario’s development charge regime for any intensification or new construction — charges in the GTA can run $50,000–$150,000+ per unit for residential intensification projects

Environmental Considerations

Ontario’s Environmental Protection Act creates significant lender concern around industrial, gas station, automotive, and dry-cleaning properties. Most institutional lenders require:

• Phase 1 Environmental Site Assessment (ESA) for any property with current or historical industrial use
• Phase 2 ESA if Phase 1 identifies concerns (Recognized Environmental Conditions)
• Record of Site Condition (RSC) filed with the Ministry of the Environment for certain transactions

Environmental issues on Ontario commercial properties can kill deals or create remediation cost requirements that dramatically alter deal economics. Budget $3,000–$7,000 for a Phase 1 ESA as a standard acquisition cost.

Commercial Mortgage Application Requirements

Ontario commercial lenders typically require:

Property Documents

• Current rent roll (all leases)
• Last 2–3 years of operating statements (T1s, income/expense summaries)
• Property tax bills
• Environmental reports if applicable
• Appraisal (lender-ordered, AACI-designated appraiser)
• Building inspection report

Borrower Documents

• Personal net worth statement
• Last 2 years personal tax returns (T1 generals)
• Last 2 years business financial statements if purchasing through a corporation
• Corporate structure documents if applicable
• Business plan for value-add or development transactions

Financial Analysis

• Pro forma income/expense projections
• DSCR analysis at proposed financing terms
• Comparable lease rates and cap rates supporting valuation

Structuring Your Ontario Commercial Mortgage

Personal vs. Corporate Ownership

Most sophisticated Ontario commercial real estate investors hold commercial properties through holding corporations or limited partnerships. Key considerations:

• Corporations provide limited liability protection
• Certain CMHC programs have restrictions on corporate borrowers — understand program-specific requirements
• Personal guarantees are almost always required by commercial lenders regardless of corporate ownership structure
• Consult a tax professional on optimal holding structure before acquisition

Term and Amortization

Commercial mortgages in Ontario typically offer:

• Terms: 1, 2, 3, 5, and occasionally 7 or 10 years
• Amortization: 20–30 years for most commercial; up to 40 years for CMHC insured multi-family
• Renewal risk: Unlike residential, commercial mortgages do not always guarantee renewal — build refinancing flexibility into your business plan

Prepayment Penalties

Commercial mortgages in Ontario typically come with more restrictive prepayment terms than residential. Common structures:

• Yield maintenance: The most punishing — lender calculates the present value of lost interest and charges accordingly
• IRD (Interest Rate Differential): Standard penalty calculation based on rate difference
• Closed with exceptions: Some lenders allow prepayment at certain trigger events (property sale, debt refinancing threshold)

Understand your prepayment terms before signing — this matters most if you intend to sell or refinance before your term expires.

Working with a Commercial Mortgage Broker in Ontario

Ontario’s commercial mortgage market is relationship-driven. The same deal presented to a lender by a knowledgeable broker with an established relationship will receive better pricing and faster approval than a borrower approaching the same lender directly.

A qualified commercial mortgage broker will:

• Identify lenders who are actively deploying capital in the current market
• Know which lenders appetite-match your property type and deal size
• Pre-screen your deal before full submission to avoid unnecessary credit pulls
• Negotiate term sheet pricing and conditions on your behalf
• Coordinate all due diligence requirements to keep the process on track

Frequently Asked Questions

What is the minimum down payment for a commercial mortgage in Ontario?

For conventional commercial mortgages in Ontario, most lenders require 25–35% down payment (65–75% LTV). For CMHC-insured multi-family properties (apartment buildings with 5+ units), down payments can be as low as 15% on acquisitions and 5–10% on new construction through the MLI Select program.

How long does commercial mortgage approval take in Ontario?

Big 5 bank approvals typically take 45–90 days from application to closing. Credit unions may move in 30–60 days. Private lenders can close in as few as 5–15 business days. The timeline depends heavily on appraisal turnaround, environmental report requirements, and the lender’s internal underwriting queue.

Do I need a property appraisal for a commercial mortgage?

Yes. Almost all Ontario commercial lenders require a formal appraisal by an AACI (Accredited Appraiser Canadian Institute) designated appraiser. The lender typically orders the appraisal directly and charges the cost to the borrower — typically $3,000–$8,000 depending on property complexity.

Can I use rental income from the property to qualify for a commercial mortgage?

Yes — in fact, for commercial mortgages, the property’s Net Operating Income (NOI) is the primary qualification metric, not personal income. Lenders calculate DSCR based on the property’s income, not your personal earnings. Personal financial strength matters for recourse guarantees but the deal itself is underwritten on property cash flow.

Is CMHC available for commercial properties in Ontario?

CMHC insured programs are available for multi-family residential (apartment buildings with 5+ units) and some mixed-use properties with majority residential components. Pure commercial properties — retail, office, industrial — are not eligible for CMHC insurance and must be financed through conventional or private sources.

What is a good cap rate for commercial property in Ontario?

Cap rates vary significantly by market and property type. GTA industrial trades at 4.0–5.5%, suburban retail at 5.5–7.0%, and secondary market Ontario commercial properties at 6.5–8.5% or higher. Ottawa multi-family stabilized product trades at 4.5–5.5%. A “good” cap rate depends on your investment strategy — higher cap rates offer more income cushion but often reflect higher risk or location disadvantages.

How does Ontario's Land Transfer Tax affect commercial financing?

Ontario Land Transfer Tax is a closing cost that must come from equity — it cannot be mortgaged. For a $3M commercial property purchase, provincial LTT alone is approximately $52,500. Add Toronto Municipal LTT and the total for a Toronto acquisition jumps to approximately $105,000. Factor LTT into your equity requirement when calculating how much capital you need to close.

What personal guarantee requirements apply to Ontario commercial mortgages?

Nearly all Ontario institutional commercial lenders require personal guarantees from principals with significant ownership stakes (typically 20%+). Limited recourse structures exist but are harder to achieve and typically reserved for very strong deals with stabilized institutional-quality assets. CMHC insured mortgages require full recourse personal guarantees from key principals.

Next Steps

Ontario’s commercial mortgage market rewards borrowers who come prepared. Understanding the lender landscape, having your documentation organized, and working with experienced commercial mortgage professionals separates investors who close deals from those who lose them.

If you’re evaluating a commercial acquisition in Ontario, the starting point is a frank analysis of your deal’s DSCR at current lending rates. If the numbers work, the right financing is available. If they don’t, understanding why helps you renegotiate the purchase price or identify a different capital structure that does work.
