CMHC commercial mortgage insurance is one of those topics that sounds boring until you realize it can save you hundreds of thousands of dollars and unlock financing that wouldn’t otherwise be possible.
Let me break down what CMHC insurance actually is, how it works, when it makes sense, and what the process looks like in 2026.
What Is CMHC Commercial Mortgage Insurance?
Canada Mortgage and Housing Corporation is a Crown corporation that insures commercial mortgages against default. When your mortgage is CMHC-insured, the lender’s risk is dramatically reduced because CMHC guarantees they’ll get paid even if you default.
This isn’t insurance that protects you as the borrower—it protects the lender. But here’s the beautiful irony: even though you’re paying for insurance that protects the lender, you get massive benefits from it.
How? Because the lender views an insured mortgage as virtually risk-free, they’ll offer you better rates, higher leverage, longer amortizations, and more flexible terms than they would on an uninsured mortgage.
Think of it this way: if you borrow $3 million to buy an apartment building without insurance, the bank is taking real risk. If the building value drops and you default, they could lose money. So they charge you 6.5% interest, require 35% down, and amortize over 20 years.
But if that same loan is CMHC-insured, the bank has zero risk. CMHC pays them if you default. So now they’re willing to charge you 5.5% interest, accept 15% down, and amortize over 30 years.
You pay an insurance premium upfront, but the improved terms often save you much more than the premium costs.
The Main CMHC Commercial Programs
CMHC has several commercial insurance programs. Let me walk through the main ones.
MLI Select (Multi-Unit Residential)
This is the big one—insurance for apartment buildings and other multi-unit residential properties.
MLI Select is available for buildings with at least 5 residential units. This includes apartment buildings, student housing, senior housing, and affordable housing projects.
The program offers loan-to-value up to 85% (meaning you only need 15% down), amortizations up to 50 years (though most lenders cap it at 30-35 years), and rates that are typically 75-150 basis points lower than uninsured financing.
In 2026, MLI Select is particularly attractive because it’s one of the few ways to get high-ratio financing on commercial real estate. Banks won’t lend over 75% without insurance—with CMHC, you can get to 85%.
Retirement Homes Program
This program specifically covers purpose-built retirement homes and seniors’ residences. Similar terms to MLI Select, but designed for the unique characteristics of seniors’ housing.
New Construction MLI
This program insures construction financing and permanent financing for new multi-unit residential developments. It covers both the construction phase and the take-out financing.
The loan-to-cost can go up to 85%, which is huge for developers who don’t want to tie up massive equity in a project.
Affordable Housing Programs
CMHC has specialized programs for affordable housing developments, including partnerships with federal and provincial housing initiatives. These can offer even more favorable terms—up to 95% loan-to-value in some cases.
CMHC Eligibility Requirements
Let’s talk about what it takes to actually qualify for CMHC insurance.
Property Requirements
The property needs to be residential rental—apartment buildings, student housing, seniors’ housing, that kind of thing. CMHC doesn’t insure office buildings, retail, industrial, or hotels (with limited exceptions).
The building needs to be in reasonable condition. CMHC will require a property condition assessment, and they won’t insure properties with significant deferred maintenance or building envelope issues. You need to fix major problems before they’ll consider insurance.
For new construction, the building needs to meet all building codes, energy efficiency requirements, and accessibility standards. CMHC is pretty particular about construction quality.
Borrower Requirements
CMHC wants to see experienced operators. For apartment buildings, they want borrowers with proven track records managing residential rental properties. If this is your first apartment building, CMHC gets nervous.
You need reasonable personal credit—generally 650+ credit score. They’ll look at your net worth, liquidity, and overall financial strength.
For larger deals (over $5 million), CMHC wants to see sophisticated ownership structures—corporations, not personal ownership. They want professional property management, not owner-managed operations.
Financial Requirements
The big one: debt service coverage ratio. CMHC typically wants to see minimum 1.20x DSCR, calculated using their underwriting assumptions.
Here’s where it gets tricky. CMHC doesn’t just take your current rent roll and expenses at face value. They apply their own underwriting standards—things like minimum vacancy assumptions (usually 3-5%), replacement reserve requirements, and standardized expense ratios.
I’ve seen deals where the owner’s actual DSCR is 1.40x, but CMHC’s underwritten DSCR is 1.15x because CMHC assumes higher expenses and vacancy than what the building actually experiences. If CMHC’s underwritten DSCR falls below 1.20x, the deal doesn’t qualify.
The CMHC Application Process
Let me walk you through what actually happens when you pursue CMHC insurance.
Step 1: Lender Pre-Approval
You don’t apply to CMHC directly—you work with an approved CMHC lender (major banks, some credit unions, some institutional lenders).
The lender does their own initial underwriting to determine if the deal is worth pursuing with CMHC. There’s no point submitting to CMHC if the bank wouldn’t approve the loan anyway.
Step 2: CMHC Application
The lender submits the application to CMHC with all the required documentation:
- Property appraisal (done by a CMHC-approved appraiser)
- Property condition assessment
- Environmental site assessment (Phase I, and Phase II if needed)
- Rent rolls and operating statements
- Borrower financial statements and credit reports
- Detailed project plans for new construction
Step 3: CMHC Review and Approval
CMHC reviews everything with a fine-tooth comb. They’re looking at property quality, location, market conditions, borrower strength, and whether the deal meets their underwriting criteria.
This process takes time—count on 6-10 weeks for a straightforward existing building, longer for new construction or complex situations.
CMHC might come back with questions or requests for additional information. They might require repairs or improvements as a condition of approval. They might approve at a lower LTV than requested if they think the appraisal is aggressive.
Step 4: Commitment and Insurance Fee
If approved, CMHC issues a commitment letter. You pay the insurance premium (which I’ll cover in a minute), and CMHC issues the insurance policy.
Step 5: Closing
The lender advances the funds, and your mortgage is now CMHC-insured. The insurance stays in place for the life of the mortgage (though it can sometimes be transferred if you refinance with a different lender).
CMHC Insurance Premiums
Let’s talk about what this actually costs.
CMHC premiums are calculated as a percentage of the loan amount, and the percentage depends on the loan-to-value ratio:
- 80.01% to 85% LTV: 2.40% premium
- 75.01% to 80% LTV: 2.00% premium
- 70.01% to 75% LTV: 1.70% premium
- 65.01% to 70% LTV: 1.30% premium
- Up to 65% LTV: 1.00% premium
These percentages are for standard MLI Select as of 2026. Other programs have different premium schedules.
Let’s make this concrete. Say you’re buying a $5 million apartment building with 15% down ($750,000), meaning you’re borrowing $4.25 million at 85% LTV.
The CMHC premium is 2.40% of $4.25 million = $102,000.
That’s a lot of money upfront. But here’s the key: you can add the premium to the mortgage. So instead of borrowing $4.25 million, you borrow $4.352 million. You’re financing the insurance premium over the life of the mortgage.
Your down payment stays at $750,000—you don’t need to come up with an extra $102,000 cash.
Does CMHC Insurance Make Economic Sense?
This is the million-dollar question. You’re paying $100k+ for insurance. Does it actually save you money?
Let me walk through a real example.
Scenario: $5 million apartment building purchase
Option A: Uninsured Conventional Mortgage
- Purchase price: $5,000,000
- Down payment (25%): $1,250,000
- Mortgage amount: $3,750,000
- Interest rate: 6.50%
- Amortization: 20 years
- Monthly payment: $28,274
- Total interest over 20 years: $3,035,760
Option B: CMHC-Insured Mortgage
- Purchase price: $5,000,000
- Down payment (15%): $750,000
- Mortgage amount: $4,250,000
- CMHC premium (2.40%): $102,000
- Total mortgage (including premium): $4,352,000
- Interest rate: 5.25%
- Amortization: 30 years
- Monthly payment: $24,037
- Total interest over 30 years: $4,301,320
At first glance, Option A looks better—you pay $1.3 million less in total interest over the life of the loan!
But look deeper:
Option A requires $500,000 more down payment. If you could invest that $500,000 elsewhere at a reasonable return (say 7% in other real estate or business investments), over 30 years that $500,000 would grow to $3.8 million.
Option B has $4,200 lower monthly payments. Over 30 years, that’s $1.5 million in cash flow that stays in your pocket to reinvest.
Plus, Option B gives you 10 extra years of amortization, which means the mortgage balance pays down slower but your required payments are lower, giving you more financial flexibility.
The math depends on your specific situation, but for many investors, the CMHC-insured option is superior even though the insurance premium seems expensive.
When CMHC Insurance Makes Sense
Let me give you some scenarios where CMHC insurance is clearly the right move.
Scenario 1: You’re capital-constrained
You have $750,000 available for a down payment, and you want to buy a $5 million building. Without CMHC, you can’t do the deal—banks want 25% down ($1.25 million). With CMHC, you can do it with 15% down.
CMHC insurance unlocks deals that wouldn’t otherwise be possible.
Scenario 2: You want to leverage up and recycle capital
You own an apartment building worth $4 million with a $2 million mortgage. You want to pull equity out to buy another building.
Refinancing conventionally, banks cap at 75% LTV = $3 million mortgage, so you can pull $1 million of equity.
Refinancing with CMHC insurance, you can go to 80% LTV = $3.2 million mortgage, pulling $1.2 million of equity.
That extra $200,000 might be the difference between buying the next property or not.
Scenario 3: You’re buying a new construction project
You’re developing a 50-unit apartment building. Construction cost is $10 million.
Conventional construction financing requires 30-35% developer equity = $3-3.5 million.
CMHC-insured construction financing can go to 85% loan-to-cost = you only need $1.5 million equity.
For developers, CMHC insurance is often essential to make projects financially viable.
Scenario 4: You want the lowest possible interest rate
Even at the same LTV, CMHC-insured mortgages get better rates. If you’re buying a $10 million building with 25% down either way, the CMHC-insured rate might be 5.25% versus 6.25% uninsured.
On a $7.5 million mortgage, that 1% difference is $75,000 per year in interest savings. Over a 5-year term, that’s $375,000—far more than the insurance premium.
When CMHC Insurance Doesn’t Make Sense
CMHC isn’t always the answer.
You’re putting 35%+ down anyway
If you have tons of capital and you’re putting 40% down, the benefits of CMHC diminish. The rate improvement might not justify the insurance premium, especially since CMHC adds time and complexity to the approval process.
The property doesn’t qualify
If your building has significant deferred maintenance, or it’s in a weak market, or it’s a non-standard property type, CMHC might decline or make approval conditional on expensive improvements.
Sometimes it’s easier to just get conventional bank financing than to jump through CMHC’s hoops.
You value speed
Conventional bank approvals can happen in 3-4 weeks. CMHC approvals take 6-10 weeks minimum. If you need to close fast, conventional financing might be your only option.
Your DSCR is weak
If your building’s cash flow is marginal and you can’t hit CMHC’s 1.20x DSCR requirement, you’re not getting approved. Conventional lenders might have more flexibility on DSCR.
CMHC vs. Other Mortgage Insurance
CMHC isn’t the only mortgage insurer in Canada. There’s also Canada Guaranty and Sagen (formerly Genworth).
For residential mortgages (owner-occupied homes), all three insurers are very similar—same premiums, same underwriting, largely interchangeable.
For commercial mortgages, it’s basically just CMHC. Canada Guaranty and Sagen do very little commercial insurance. CMHC dominates the market.
So when we talk about insured commercial mortgages, we’re really talking about CMHC.
Working with CMHC-Approved Lenders
Not all lenders are CMHC-approved, and not all CMHC-approved lenders are active in insured lending.
The major banks (RBC, TD, BMO, Scotiabank, CIBC) are all very active in CMHC-insured apartment financing. Some credit unions are approved but less active. There are also some institutional lenders and insurance companies that focus heavily on CMHC-insured multifamily.
Here’s the thing: even within the same bank, different branches and different underwriters have varying levels of experience with CMHC. Some bank commercial lenders do mostly conventional uninsured deals and rarely touch CMHC. Others specialize in it.
Working with a broker like Creek Road Financial Inc., we know which lenders and which specific underwriters are most active and efficient with CMHC applications. We can steer your deal to people who know the process cold and can move it through smoothly.
Recent CMHC Changes in 2026
CMHC has made some notable updates recently:
Enhanced Green Building Incentives
CMHC now offers 15% premium refunds for buildings that achieve certain energy efficiency certifications. For a $100,000 premium, that’s $15,000 back—meaningful money.
Streamlined Processing for Experienced Borrowers
If you’ve done multiple CMHC-insured deals successfully, CMHC now has an expedited review process that can cut 2-3 weeks off the timeline.
Increased Focus on Affordability
CMHC is prioritizing applications that include affordable housing units. If 20%+ of your units are at below-market rents, you get preferential treatment in the application queue and sometimes premium discounts.
Tighter Environmental Requirements
CMHC is now requiring Phase I environmental assessments on all properties (they were sometimes waived before), and they’re more conservative on properties with any environmental concerns.
The Bottom Line on CMHC Insurance
CMHC commercial mortgage insurance is a powerful tool for apartment building and multi-unit residential financing. It enables higher leverage, better rates, longer amortizations, and access to capital that wouldn’t otherwise be available.
The insurance premium is substantial—typically $100,000+ on a multi-million dollar deal—but the improved terms often provide far more value than the premium costs.
CMHC makes most sense when you’re capital-constrained, when you want maximum leverage, when you’re developing new construction, or when you want the absolute best rates.
It’s not right for every deal—the approval process is slower and more rigorous than conventional financing, and properties need to meet strict quality standards.
But for serious apartment building investors and developers, understanding CMHC insurance and how to leverage it effectively is essential.
