A triplex — a building with three self-contained residential units — offers Canadian investors more rental income than a duplex while still qualifying for owner-occupied financing if you live in one unit. Triplexes sit at a sweet spot between small-scale landlording and larger multi-family investing, offering scale without the complexity of commercial financing.
What Makes a Triplex Attractive?
- Three income streams — rent from up to three units reduces vacancy risk compared to a single-family rental
- Owner-occupied financing available — live in one unit, rent the other two with as little as 5–10% down (under $1M)
- Residential mortgage rules apply — 1–4 unit properties use residential (not commercial) financing
- Scalable management — one property, three units; more efficient than three separate properties
- Stronger cash flow than a duplex — two rental units instead of one offset the mortgage more aggressively
Triplex Financing in Canada
In Canada, properties with 1–4 units are classified as residential for mortgage purposes. This is a critical advantage:
| Situation | Min. Down Payment | CMHC Insured? |
|---|
| Owner-occupied triplex (under $1M) | 5–10% | Yes |
| Owner-occupied triplex ($1M–$1.5M) | 20% | No |
| Investment triplex (not owner-occupied) | 20% | No |
| 4+ unit property (any) | 20–25%+ | No (commercial rules) |
Owner-occupying a triplex with 10% down gives you access to insured mortgage rates (typically lower than uninsured) and a much smaller down payment than a pure investment purchase. The two rental units can dramatically reduce your net carrying cost.
Cash Flow Example: Triplex in Ottawa
Purchase price: $850,000
Down payment (10%): $85,000
Mortgage (insured, 5.4%, 25yr): ~$4,400/month
Unit 1 (owner-occupied): —
Unit 2 (2BR rental): $2,000/month
Unit 3 (1BR rental): $1,600/month
Total rental income: $3,600/month
Property tax: $500/month
Insurance: $200/month
Maintenance reserve: $350/month
Net housing cost to owner: $4,400 + $500 + $200 + $350 − $3,600 = $1,850/month
Tax Treatment of a Triplex
If you live in one unit and rent the other two, you report rental income and expenses for the two rental units on Schedule T776. Shared expenses (mortgage interest, insurance, property taxes) are prorated — if you occupy 1 of 3 equal units, 67% of shared expenses are deductible.
On sale:
- Your unit (1/3 of property) qualifies for the principal residence exemption
- The rental portion (2/3) is subject to capital gains at the 50% inclusion rate
- Any CCA claimed on rental portions triggers recapture at 100%
Managing Three Units
A triplex is still small enough for self-management for most investors. Key management considerations:
- Screen tenants carefully — you'll be living next door or in the same building
- Clearly define maintenance responsibilities in each lease
- Set up separate banking for rental income and expenses
- Understand provincial landlord-tenant rules (Ontario RTA or BC RTA)
- Maintain a professional relationship with tenants even when living on-site
Triplex vs. Duplex vs. Fourplex
| Property Type | Rental Units | Min. Down (Owner-Occ.) | Cash Flow Potential |
|---|
| Duplex | 1 rental | 5% | Moderate |
| Triplex | 2 rentals | 10% | Good |
| Fourplex | 3 rentals | 10% | Strong |
| 5+ units | 4+ rentals | 20–25%+ | Strong (commercial rules) |
What to Look for When Buying a Triplex
- All three units must be legal and permitted — verify with the municipality
- Separately metered utilities are ideal — avoids disputes over usage
- Review existing leases and current rents before closing
- Check the condition of shared systems: roof, furnace, plumbing, electrical panel
- Verify fire code compliance: separate exits, smoke detectors, CO alarms
- Confirm zoning permits three-unit residential use

Conclusion
A triplex is one of the most compelling real estate investments available to Canadians. Owner-occupying a triplex lets you use low-down-payment insured financing, collect rent from two units, and build equity — all while keeping housing costs far below renting. Focus on legal units in strong rental markets, analyze the cash flow carefully, and the triplex can form a solid cornerstone of a Canadian real estate portfolio.
