Multi-Family Mortgage Financing in Ontario
Multi-family mortgages in Ontario finance apartment buildings and rental properties with 5 or more residential units. These properties are classified as commercial under OSFI guidelines and are underwritten using DSCR and NOI rather than personal income. Conventional financing provides up to 75% LTV. CMHC Standard Multi-Unit Insurance allows 85% LTV. CMHC MLI Select unlocks up to 95% LTV and 50-year amortization for qualifying properties. Rates start from 4.99% for CMHC-insured multi-family. lendsimpl arranges multi-family financing from $500K to $50M+ across Ontario — FSRA Brokerage #13763.
What Is a Multi-Family Mortgage in Ontario?
In Ontario, residential properties with 1–4 units use residential mortgage underwriting: lenders qualify the borrower based on personal income, credit score, and the OSFI B-20 stress test. Properties with 5 or more unitscross into commercial territory. The lender underwrites based on the property's ability to generate income — specifically its Net Operating Income (NOI) and Debt Service Coverage Ratio (DSCR).
This distinction matters significantly for financing strategy. A 4-plex with a strong personal income borrower can access high-ratio residential mortgage insurance at 80%+ LTV. A 6-unit building must meet commercial criteria regardless of borrower income — but gains access to CMHC commercial multi-unit programs with up to 95% LTV through MLI Select.
Key threshold: 5 units is the dividing line between residential and commercial multi-family underwriting in Ontario. A duplex, triplex, or fourplex is residential. A fiveplex and above is commercial multi-family.

Who Qualifies for a Multi-Family Mortgage in Ontario?
Eligibility for Ontario multi-family financing is primarily assessed on the property's income performance — not just the borrower's personal income.
Individual investors
Individuals purchasing or refinancing an apartment building or multi-unit rental property. Property income is the primary qualification factor.
Corporations / holding companies
Ontario numbered companies, LLPs, or professional corporations holding rental real estate. Most lenders accept corporate borrowers with appropriate personal guarantees.
Self-employed borrowers
Self-employment is not a barrier for multi-family financing because lenders underwrite on property NOI, not T4 income. Self-employed Ontario investors access the same programs as T4 employees.
Newcomers to Canada
Non-residents and newcomers can qualify for Ontario multi-family financing through institutional or B-lenders. Some CMHC programs require Canadian residency.
Borrowers with bruised credit
B-lenders and private multi-family lenders weigh property performance over borrower credit. A property with strong DSCR can often qualify even with credit issues.
CMHC MLI Select applicants
To use CMHC MLI Select, the property must score 50+ points on affordability, energy efficiency, and accessibility criteria. Borrower must meet standard CMHC underwriting requirements.

Frequently Asked Questions — Multi-Family Mortgage Ontario
What is a multi-family mortgage in Ontario?
A multi-family mortgage finances residential rental properties with 5 or more units in Ontario. Unlike 1–4 unit properties (residential mortgage rules), 5+ unit properties use commercial underwriting criteria: Net Operating Income (NOI), Debt Service Coverage Ratio (DSCR), and commercial LTV limits. Financing options include CMHC-insured mortgages (standard and MLI Select), institutional lenders, B-lenders, and private multi-family lenders.
How much can I borrow on a multi-family property in Ontario?
Maximum LTV: Conventional = 75%. Standard CMHC multi-unit = 85%. CMHC MLI Select 75 pts = 90%. CMHC MLI Select 100 pts = 95%. Private = up to 80%. The 95% LTV available through CMHC MLI Select is the highest leverage available in the Ontario multi-family market for qualifying properties.
What DSCR do lenders require for Ontario multi-family mortgages?
Minimum DSCR by lender tier: Institutional bank = 1.20x–1.25x. Standard CMHC = 1.20x. CMHC MLI Select (100 pts) = 1.10x. B-lender = 1.15x–1.20x. Private = 1.05x–1.10x. DSCR = NOI ÷ Annual Debt Service. CMHC MLI Select's 50-year amortization reduces annual debt service, which frequently resolves marginal DSCR situations.
What is the difference between a 4-unit and 5-unit property for Ontario mortgages?
1–4 unit properties use residential mortgage underwriting (based on borrower income, high-ratio insurance available, OSFI B-20 stress test). 5+ unit properties use commercial multi-family underwriting (NOI, DSCR, commercial LTV caps). Conventional financing for 5+ units caps at 75% LTV. CMHC multi-unit programs allow up to 85–95% LTV.
Can I use CMHC insurance on an Ontario apartment building?
Yes — for properties with 5+ units. CMHC offers Standard Multi-Unit Insurance (up to 85% LTV, 40-year amortization) and MLI Select (up to 95% LTV, 50-year amortization for qualifying properties). Both programs offer lower rates than conventional financing because the CMHC insurance guarantee reduces lender risk.
What are current multi-family mortgage rates in Ontario?
Multi-family mortgage rates in Ontario as of Q2 2026: CMHC MLI Select = 4.99–6.20%. Standard CMHC = 5.20–6.50%. Institutional/bank = 5.90–7.50%. B-lender = 7.99–9.99%. Private = 9.99–13%. CMHC-insured rates are the lowest available because the insurance eliminates lender default risk.
How long does a multi-family mortgage take to close in Ontario?
CMHC-insured (standard or MLI Select) = 6–12 weeks. Institutional bank = 6–10 weeks. B-lender = 4–8 weeks. Private lender = 2–4 weeks. Private lenders are the fastest option for time-sensitive acquisitions or bridge financing needs.
Can I get a multi-family mortgage with low DSCR or bad credit?
Yes, through B-lenders or private multi-family lenders. B-lenders accept DSCR as low as 1.15x and weigh property performance more heavily than credit score. Private multi-family lenders may accept DSCR of 1.05x or below 1.0x in equity-rich situations (35–40% down payment typically required). Credit score is a secondary factor for private lenders who focus on property equity.
