CMHC MLI Select: A Complete Guide for Toronto Multiplex Owners
TESA · July 13, 2026 · 11 min read
CMHC MLI Select is a points-based mortgage insurance product for rental buildings of five or more units. A project earns points across three categories: affordability, energy efficiency, and accessibility. That score, not a loan officer's discretion, sets the loan-to-value ceiling, the amortization period, and part of the insurance premium. A borrower needs a minimum of 50 points to access any MLI Select flexibility, with further tiers at 70 and 100 points unlocking better terms still. For a Toronto infill project of five to ten units, most of what earns points (an efficient envelope, a deliberate unit mix, a handful of accessible units) is close to what a well-run build already wants to do anyway. The commitments that convert into points have to be locked in before permits are drawn, not negotiated after the building is designed.
What CMHC MLI Select Is, and Why It Exists
MLI Select replaced CMHC's earlier MLI Flex product on March 7, 2022. It's mortgage loan insurance: coverage CMHC sells to lenders that lets them offer higher leverage than an uninsured commercial mortgage would justify. The product targets buildings with five or more rental units. In exchange for reduced premiums, higher loan-to-value ratios, and longer amortization, the borrower commits to measurable outcomes in affordability, energy efficiency, or accessibility, scored through CMHC's points system.
Eligibility has a floor: a minimum of five rental units (50 units or beds for retirement and care homes), non-residential space capped at 30% of gross floor area and 30% of total lending value, and every unit built to a 100% "visitable" accessibility standard with barrier-free common areas. None of that is optional; it's the gate you clear before the points system even starts scoring you.
The policy logic behind it shows up in the rental data. Toronto's purpose-built rental vacancy rate reached roughly 3% in 2025, the highest since the pandemic and up from about 2.2% the year before, with average purpose-built rent across the Toronto CMA sitting around $1,917 a month. CMHC isn't just financing more supply; it's using the points system to steer that supply toward specific outcomes: lower operating rents for a share of units, lower-carbon buildings, more accessible units, rather than extending the same premium relief to a building that delivers none of that.
The Points System, Category by Category
Affordability
Affordability points require a minimum 10-year commitment, and the thresholds differ for new construction versus existing buildings. Stretching the commitment to 20 years adds a further 30 points on top of whichever tier you hit.
| Points | New construction | Existing property |
|---|---|---|
| 50 | 10% of units at or below 30% of median renter income | 40% of units at or below 30% of median renter income |
| 70 | 15% of units | 60% of units |
| 100 | 25% of units | 80% of units |
A new sixplex only needs one unit (roughly 15-17% of six) priced at 30% of median renter income to clear the 70-point affordability threshold. An existing building being refinanced under MLI Select needs a much larger share of its unit count committed, which is the main reason new construction and acquisition-refinance deals score this category so differently.
Energy efficiency
New construction is scored against two baselines at once: the 2020 National Energy Code for Buildings (NECB) and the 2020 National Building Code (NBC), each Tier 1. You only need to clear one of the two thresholds at each point level, not both.
| Points | vs. NECB 2020 Tier 1 | vs. NBC 2020 Tier 1 |
|---|---|---|
| 20 | minimum 25% better | minimum 20% better |
| 35 | minimum 50% better | minimum 40% better |
| 50 | minimum 60% better | minimum 70% better |
Existing properties are scored differently, on greenhouse-gas intensity reduction against the building's current performance: 15% reduction for 20 points, 25% for 35 points, 40% for 50 points.
One date matters for anyone modelling a project past this year. Energy attestations can still be benchmarked against the older 2015 NBC or 2017 NECB standards until September 30, 2026. After that, the reference standard becomes the 2020 NBC and 2020 NECB across the board, a stricter baseline that will earn fewer points for an identical building design. A project that would clear the 35-point tier against the 2017 NECB today may only clear 20 points against the same design once the 2020 baseline becomes mandatory.
Accessibility
| Points | Requirement |
|---|---|
| 20 | 15% of units built accessible to CSA B651:23, or certified to a recognized universal design standard |
| 30 | 15% of units accessible plus 85% built to universal design, or building-wide accessibility certification |
What a Toronto 5-to-10 Unit Building Can Realistically Hit
Toronto defines a "multiplex" as a two-, three-, or four-unit building, permitted as-of-right citywide in R, RD, RS, RT, and RM residential zones provided the building meets its zone's setback, height, and lot-coverage rules. That definition matters for MLI Select because the program's floor is five units: a classic fourplex is one unit short of eligibility on its own. Since June 2025, Toronto allows multiplexes of up to six units as-of-right, but only within the Toronto and East York Community Council district and in Ward 23 (Scarborough North); six-unit as-of-right permission is not yet citywide, though a separate city study is considering extending it to all low-rise neighbourhoods.
A sixplex built in one of those two areas clears the unit-count gate cleanly. Two other Toronto rules feed the same pro forma: the city has required no minimum on-site parking for new residential development, including multiplexes, since February 3, 2022, and multiplexes of up to four units are generally exempt from development charges and cash-in-lieu parkland fees under Municipal Code sections 415-6 and 415-30 (reporting suggests Council extended a version of that exemption toward six-unit buildings in 2025 budget decisions, though that should be confirmed against the current by-law text before it's relied on in a specific deal). None of that changes the setback envelope itself; a multiplex uses the same setbacks as any other permitted building in its zone.
Put those pieces together and a well-designed six-unit new-build in the expanded zone can realistically stack: 15% affordability (one unit at 30% of median renter income) for 70 points on its own, or a smaller affordability commitment paired with a 20-25% efficient envelope and a couple of accessible units to land in the same 70-to-100 range from a blend of categories rather than maxing out any single one.
MLI Select vs. CMHC Standard vs. Conventional Bank Financing
| Conventional bank | CMHC Standard | CMHC MLI Select | |
|---|---|---|---|
| Max leverage | roughly 75% LTV | up to 85% LTV | up to 95% LTV (existing, 70+ pts) / up to 95% LTC (new construction, per CMHC's own table, from as few as 50 pts) |
| Amortization | roughly 25 years | up to 40 yrs (existing) / 50 yrs (new construction) | up to 40-50 yrs (existing) / up to 40-50 yrs (new construction), scaled to points |
| Minimum DCR | typically 1.20x-1.30x | not points-based | minimum 1.10x at every tier |
| Points system | none | none | required, 50 pts minimum |
| Minimum units | none | 5 | 5 (50 beds for retirement/care) |
CMHC's own MLI Select tables show up to 95% loan-to-value for existing properties at 70 points and above, and up to 95% loan-to-cost for new construction starting as low as 50 points, with amortization scaling from 40 years at the entry tier to 45 at 70 points and 50 at 100 points (the top tier also opens a limited-recourse option). A secondary industry source publishes a different new-construction tier structure (90% only at 70 points, 95% reserved for 100-plus), which conflicts with CMHC's published table. Treat CMHC's own page as authoritative and re-verify the live tier table with CMHC or an approved lender before underwriting a specific deal.
The DCR gap is where MLI Select does quiet work on a marginal deal. A conventional lender testing at 1.25x will reject a rent roll that clears CMHC's 1.10x floor with room to spare, which is often the difference between a lot penciling and not.
Effective July 14, 2025, CMHC moved to a standardized, risk-based premium approach across all multi-unit insured products, MLI Select included. Pricing now ties to loan-specific risk factors such as down payment level and new-construction status, and a discount schedule reduces total premium based on the affordability, accessibility, or energy outcomes achieved. That change is anchored to OSFI's revised Mortgage Insurer Capital Adequacy Test guideline. There's a cost to stretching amortization, too: an extended-amortization surcharge of roughly 0.25% of the net loan amount applies for every five years past the 25-year standard, meaning a full 45-to-50-year amortization can add somewhere close to a full percentage point to the base premium before any MLI Select discount is netted against it. Exact current base premium percentages live only in CMHC's fees-and-premiums schedule; confirm the live figure with CMHC or an approved lender before quoting a rate to a client.
Where the Points Actually Get Decided
MLI Select's categories aren't paperwork you assemble after the building is designed: they're design inputs. Unit mix and rent-setting for the affordability tier, envelope assemblies and mechanical systems for the energy tier, and unit layout for the accessibility tier all get fixed at the permit-drawing stage. Changing the unit count, the envelope spec, or which units are barrier-free after a permit set is drawn means redrawing and refiling, which costs both time and the points that depend on those decisions.
Ontario's own building code adds a wrinkle worth flagging here. The 2024 Ontario Building Code, in effect since January 1, 2025 after a grace period to March 31, 2025, governs energy compliance for new residential construction through Supplementary Standard SB-12, which sets prescriptive energy packages by climate zone. That's a different measurement system from the graduated, percentage-above-baseline tiers CMHC uses to score MLI Select energy points against the NBC and NECB. Meeting Ontario's minimum code does not automatically translate into MLI Select points; the two systems have to be checked separately, and a design that clears SB-12 with room to spare can still miss the 20-point energy tier if nobody modelled it against the NBC/NECB baseline specifically.
We model MLI Select scoring alongside conventional financing during feasibility, before a permit set exists, because by the time drawings are done, the unit mix and envelope decisions that drive the score are already locked in.
Worked Example: One Toronto Sixplex, Two Financing Paths
Take a hypothetical six-unit new-build in the expanded as-of-right zone, illustrative all-in cost of $3,000,000 (land plus hard and soft costs), used here only to show the shape of the delta, not as a benchmark figure.
Conventional bank financing: roughly 75% LTV caps the loan at about $2,250,000, leaving roughly $750,000 in required equity, on a roughly 25-year amortization, tested against a typical 1.20x-1.30x DCR.
MLI Select at 70 points (achieved here through a 15% affordability commitment plus a modest energy package): up to 95% LTC on CMHC's own table brings the loan to about $2,850,000, cutting required equity to roughly $150,000, a swing of about $600,000 in equity that doesn't have to come from the sponsor's pocket, on up to a 45-year amortization tested against a 1.10x DCR floor.
On the income side, using a rounded, approximate figure of roughly $2,000 a month per unit (in the range of the Toronto CMA's 2025 average purpose-built rent), six units generates about $144,000 a year in gross rent before vacancy and operating costs. At CMHC's 1.10x DCR floor, that rent roll has more room to qualify than it would against a conventional lender's 1.20x-1.30x test, which is often exactly the margin that decides whether a marginal lot gets built. The tradeoff sits on the premium side: stretching amortization from 25 to 45 years adds roughly four 5-year increments of the amortization-extension surcharge, worth checking against CMHC's current fee schedule alongside whatever MLI Select discount the affordability and energy commitments earn back.
Point-Losing Mistakes and Disqualifiers
- Unit count that doesn't clear five. Toronto's own multiplex definition tops out at four units citywide, and six-unit as-of-right is limited to the Toronto and East York district and Ward 23. A project outside those areas that can't legally reach five units doesn't qualify for MLI Select at all, regardless of how well it would score.
- Assuming Ontario Building Code compliance equals energy points. SB-12's prescriptive, climate-zone-based packages are a different measurement than CMHC's percentage-above-NBC/NECB tiers. Meeting code minimums doesn't automatically clear even the 20-point energy tier.
- Designing the building first, then checking the score. Affordability unit selection, envelope specs, and accessible unit layout all have to be locked before permits are filed. Retrofitting a design to hit a higher tier after drawings are done means refiling.
- Trusting a single third-party tier table. Published tier structures for new-construction LTC vary between CMHC's own page and secondary industry sources. Re-verify the live table with CMHC or an approved lender before underwriting off a cached table.
- Missing the September 30, 2026 energy benchmark cutoff. Attestations against the older 2015 NBC or 2017 NECB standards are only available until that date; after it, every project scores against the stricter 2020 baseline, which can drop a design out of a points tier it would have cleared under the old benchmark.
What CMHC Actually Asks For
Energy points require a formal attestation, and which reference standard it's benchmarked against depends on when it's filed (the 2015 NBC/2017 NECB option closes September 30, 2026). Premium pricing since July 14, 2025 is risk-based and loan-specific, factoring down payment level and new-construction status, with the MLI Select discount applied on top based on the affordability, accessibility, or energy outcomes actually documented, not just targeted. That means the file has to carry evidence the commitments are real: which units are priced at what share of median renter income, which accessibility standard the built units meet, and which energy modelling backs the attestation, not just a design intent stated at application.
How This Fits the Rest of the Financing Picture
MLI Select is one lever in a financing stack that starts with a feasibility study (what the lot can legally hold and what it costs to build) and ends with a funded construction loan. The points system only pays off if the unit mix, envelope, and accessibility decisions it rewards are baked into the project before a lender ever sees an application. Treat it as a design constraint to hit deliberately, not a form to fill out once the building is already drawn.
