Overview
This guide answers the question Ontario multi-family investors should be asking before they ever call a broker: How do I underwrite and structure an Ontario multiplex deal using MLI Select?
The financing mechanics sit at cornellmortgages.ca. This guide covers the acquisition strategy, the underwriting framework, and the advisory lens through which every Perseverance Asset Management deal is evaluated. If you are looking for a mortgage quote, book through the Members Portal or visit cornellmortgages.ca. If you are looking to understand how to model, structure, and evaluate an Ontario multi-family acquisition using CMHC's MLI Select program — read on.
What Is MLI Select?
MLI Select is CMHC's multi-unit mortgage loan insurance product designed to reward affordability, energy efficiency, and accessibility commitments with improved financing terms. It is not a grant, a subsidy, or a government loan program. It is mortgage loan insurance — the same structural instrument as standard CMHC insurance, with a point-based incentive layer built on top.
The program underwrites the building, not the borrower. This is the single most important distinction for investors transitioning from residential to commercial real estate financing. There is no income qualification, no TDS/GDS calculation, and no personal debt service ratio applied to the investor. The operative financial constraint is Debt Service Coverage Ratio (DSCR) — the relationship between the property's net operating income and its mortgage payment.
What MLI Select Unlocks
| Point Tier | LTV | Amortization | Recourse |
|---|---|---|---|
| 50 points | Up to 95% | Up to 40 years | Full recourse |
| 70 points | Up to 95% | Up to 45 years | Full recourse |
| 100 points | Up to 95% | Up to 50 years | Limited recourse |
The Three Point Categories
MLI Select awards points across three categories. The minimum qualifying score is 50 points. Maximum possible is 180 points (100 affordability + 50 energy + 30 accessibility).
Affordability Points (up to 100 pts)
CMHC defines an affordable unit as one rented at or below 30% of the median renter household income for the subject CMA — before tax. These figures are published annually in a downloadable XLSX at cmhc-schl.gc.ca and represent the authoritative threshold for every application. Do not use third-party estimates.
Ontario CMA Affordability Thresholds (CMHC 2019 Census basis):
| CMA | Median Renter Income | Affordability Threshold (30%) |
|---|---|---|
| Hamilton | $44,400 | $1,110/mon |
| Kitchener-Waterloo-Cambridge | $57,000 | $1,425/mon |
| London | $39,600 | $990/mon |
| Ottawa-Gatineau (ON) | $61,400 | $1,535/mon |
| Barrie | $58,900 | $1,473/mon |
| Oshawa | $54,000 | $1,350/mon |
| Mississauga | $49,000 | $1,225/mon |
| Toronto CMA | $53,900 | $1,348/mon |
| Guelph | $57,400 | $1,435/mon |
| Kingston | $52,500 | $1,313/mon |
| St. Catharines-Niagara | $41,900 | $1,048/mon |
| Brantford | $40,300 | $1,008/mon |
| Greater Sudbury | $46,500 | $1,163/mon |
| Windsor | $34,000 | $850/mon |
| Sarnia | $25,800 | $645/mon |
Point tiers for existing properties:
| % of Units at or Below Threshold | Points |
|---|---|
| 40% of units | 50 pts |
| 60% of units | 70 pts |
| 80% of units | 100 pts |
| New construction — 40% (10-yr commitment) | 50 pts |
| New construction — 60% (10-yr commitment) | 70 pts |
| 20+ year affordability commitment (bonus) | +30 pts |
Energy Efficiency Points (up to 50 pts)
A preliminary energy audit costs approximately $2,500. Actual upgrade costs range from $100,000 to well into the millions depending on building size, vintage, and the scope of mechanical and envelope work required.
| Level | Efficiency Improvement | Points |
|---|---|---|
| Level 1 | 15% improvement over baseline | 20 pts |
| Level 2 | 25% improvement | 35 pts |
| Level 3 | 40% improvement | 50 pts |
Critical deadline: CMHC's energy scoring baseline shifts from 2015/2017 codes to the 2020 NBC/NECB on September 30, 2026. Any deal with a timeline extending past that date must be modelled against the 2020 standard.
Accessibility Points (up to 30 pts)
Universal-design features — grab bars, wider doorways, accessible building entry, lever-style hardware — can deliver 20–30 points at relatively modest per-unit cost. Scope these into the renovation budget during acquisition underwriting, not after the fact.
MLI Select vs. ACLP: Understanding the Distinction
MLI Select and the Affordable Construction Lending Program (ACLP) are frequently conflated. They serve different stages of the capital stack.
| Feature | MLI Select | ACLP |
|---|---|---|
| Purpose | Acquisition, refinance, or construction take-out | Construction phase financing |
| Sizing basis | DSCR and LTV of completed asset | Up to 100% of residential construction costs |
| When used | At purchase or stabilization | During active construction |
| Typical sequence | Take-out after ACLP | Before MLI Select take-out |
For new builds: ACLP finances the construction phase, then MLI Select provides the permanent financing at stabilization.
How to Model MLI Select Into Your Acquisition Underwriting
Step 1: Rent Roll Analysis
Pull the current rent roll and compare every unit's in-place rent against the CMHC affordability threshold for the subject CMA. Count the percentage at or below the threshold. Map to the point tier. This is due diligence step one — it costs nothing and determines whether the deal's existing rent roll carries the point stack without any capital commitment.
Step 2: DSCR Sizing
MLI Select's minimum DSCR is 1.10x. Approved lenders typically stress to 1.12x internally. Advisory standard is 1.20x+.
Conservative underwriting assumptions:
| Metric | Conservative Assumption |
|---|---|
| Vacancy & credit loss | 5–8% of GPR |
| Property management (outsourced) | 5–8% of EGI |
| Maintenance / R&M | $800–$1,200/unit/year |
| Insurance | Verify from current declaration |
| Property tax | Verify with municipality; flag reassessment risk post-sale |
| Minimum DSCR (MLI Select) | 1.10x |
| Target DSCR (advisory standard) | 1.20x+ |
Step 3: Point Strategy
If affordability points alone reach 50 or 70, the deal qualifies without energy or accessibility capital. If not, model the energy upgrade cost against the amortization benefit: moving from 40-year to 45-year or 50-year amortization materially improves DSCR and monthly cash flow on larger assets.
Step 4: Premium Sizing
CMHC's premium is applied to the insured loan amount. The premium rate depends on LTV tier. For deals at 85%+ LTV, verify the current premium schedule directly from CMHC's Multi-unit Fees and Premiums page at cmhc-schl.gc.ca — premium rates were updated in 2025 and an amortization surcharge applies for extended amortization tiers.
Deal Experience
In 2025, Perseverance Asset Management had the pleasure of acting as a Consultant on the following five multi-family MLI Select transactions, acting as a Consultant for a private Fund through Perseverance Asset Management:
| Project | Location | Units | MLI Select Tier | Key Structure Element |
|---|---|---|---|---|
| Project 1 | Eastern Canada | 12 units | 70 pts | Affordability + accessibility; vintage 1972 walk-up |
| Project 2 | Eastern Canada | 24 units | 100 pts | Full affordability + Level 2 energy; 50-year amortization |
| Project 3 | Eastern Canada | 18 units | 50 pts | Affordability-only; rent roll carried the point stack at acquisition |
| Project 4 | Eastern Canada | 36 units | 100 pts | Limited recourse structure; new construction take-out |
| Project 5 | Eastern Canada | 60 units | 70 pts | Mixed affordability/energy; 45-year amortization |
Ontario Market Context
Ontario's secondary markets offer the most compelling MLI Select entry points in 2026. The affordability threshold in markets like Windsor ($850/mon), Sarnia ($645/mon), and Brantford ($1,008/mon) means a high proportion of existing in-place rents in older vintage stock already qualify — reducing or eliminating the need for capital-intensive upgrades to reach the 50 or 70-point tier.
Hamilton, Kitchener-Waterloo, and London represent the mid-tier sweet spot: thresholds in the $990–$1,425/mon range, active multi-family transaction markets, and sufficient rental demand depth to support stabilized DSCR at 1.20x+ without aggressive rent assumptions.

Frequently Asked Questions
What is the difference between MLI Select and standard CMHC multi-unit insurance?
MLI Select is a point-based incentive layer on top of standard CMHC multi-unit mortgage loan insurance. Standard CMHC multi-unit insurance provides insured financing for rental properties without requiring affordability, energy, or accessibility commitments. MLI Select rewards those commitments with higher LTV (up to 95%), longer amortization (up to 50 years), and — at the 100-point tier — limited recourse.
Does MLI Select require a rent reduction?
No. MLI Select requires that a defined percentage of units rent at or below the CMHC affordability threshold — it does not require you to reduce existing rents below that threshold. If in-place rents already meet the threshold, the affordability points are embedded in the asset at acquisition.
What is the minimum property size for MLI Select?
MLI Select applies to properties with 5 or more units.
What is ACLP and how does it relate to MLI Select?
ACLP (Affordable Construction Lending Program) finances the construction phase of new multi-family builds, covering up to 100% of residential construction costs. MLI Select then provides the permanent insured mortgage at stabilization. For new builds, they are sequenced: ACLP for construction, MLI Select take-out at completion.
When does the energy scoring baseline change?
CMHC's energy scoring baseline shifts from 2015/2017 codes to the 2020 National Building Code / National Energy Code for Buildings on September 30, 2026. Any deal with a closing or application date after September 30, 2026 must be modelled against the 2020 standard.
