The federal program that finances small rental buildings at terms no bank will match — the points, the premiums, the 1.10 test, and the honest math on what it means for a five- or six-unit build on your lot.
If you own a Toronto lot and you're thinking about building rental units on it, one federal program decides whether your project is a rounding error on your net worth or a transformation of it. CMHC's MLI Select insures mortgages on rental buildings of five or more units — and because the government backs the loan, lenders offer terms that don't exist anywhere else in Canadian real estate.
MLI Select scores projects across three categories — energy efficiency, affordability, and accessibility. You need 50 points for the entry tier, 70 for better, 100 for the best. Here's what a decade of program mechanics boils down to for a small Toronto build:
| Tier | Points | Max amortization | Premium discount |
|---|---|---|---|
| Entry | 50 | 40 years | 10% |
| Enhanced | 70 | 45 years | 20% |
| Maximum | 100 | 50 years | 30% |
The practical Toronto path is energy efficiency. Fifty points comes from building roughly 40% better than the building-code baseline — which a well-designed new multiplex reaches through heat pumps, envelope quality and air-sealing that good builders now treat as standard. Fifty points at 95% financing and 40-year amortization is the sweet spot: everything above it costs more than it returns for most small buildings.
Why we don't chase affordability points in Toronto: the affordability pathway requires renting units at 30% of median renter income — roughly $1,300–1,400/month here, against market rents of $3,000+. On a five-unit building that's $20,000/year of foregone rent to save a fraction of that in premium. The math almost never works in this city. In cheaper markets it can — which is why generic national advice gets this wrong.
CMHC will not insure a loan whose payments exceed your building's net operating income divided by 1.10. In plain English: the rents, after operating costs, must cover the mortgage payments with 10% to spare. This — not the 95% headline — is usually what determines your loan.
Worked example, a five-unit new build in North York: four 3-bed/2-bath units at $3,200/month plus a garden suite at $2,800 grosses about $187,000/year. After a 2.5% vacancy allowance and CMHC-benchmark operating costs (≈22% of income), net operating income lands near $143,000. Divide by 1.10, spread over 40 years at the qualifying rate, and the rents support roughly $2.6–2.7M of loan — typically enough to cover the entire construction cost, the soft costs, and the discharge of an existing mortgage, with the land as your equity.
CMHC charges a one-time insurance premium of roughly 5% of the loan (rates rose in July 2025, and they scale with amortization length and your discount tier). On a $2.5M loan that's about $125,000 — real money, and any pro forma that hides it is lying to you. It's capitalized into the mortgage, not paid in cash, and it buys the rate and amortization advantages worth several times that over the life of the loan. Price it in. We always do.
