Toronto Sixplex Builder
Six revenue streams on a single lot. We design and build sixplexes with flexible unit mixes, CMHC MLI Select eligibility, and neighbourhood-enhancing architecture — from feasibility to keys in hand.
Why Build a Sixplex in Toronto
A Toronto sixplex delivers strong rental income without sacrificing neighbourhood character. Six revenue streams on a single lot, flexible unit mixes to hedge vacancy risk, and a low-rise form that fits naturally into established streets. It's the scale that makes financial sense while respecting the fabric of Toronto's best neighbourhoods.
Our Sixplex Approach
We've built enough sixplexes to know what makes the difference between a standard build and a high-performing asset.
Flexible sixplex unit combinations that maximize rental income and appeal to a diverse tenant base across six self-contained suites.
High-efficiency mechanical systems, quality insulation, and durable materials that reduce ongoing costs for sixplex owners and tenants.
Thoughtfully designed sixplex access points offering the ideal balance of privacy and community connection across all six units.
Sixplex architecture crafted to complement existing character while adding contemporary presence to Toronto's established streets.
Construction quality and refined finishes that ensure your Toronto sixplex stands the test of time with minimal maintenance.
Private balconies, patios, in-suite laundry, and bike storage — functional amenities that attract and retain quality sixplex residents.
Sixplex Financing
We build sixplexes that qualify for Canada's best rental financing program — often the difference between a project that pencils and one that doesn't.
Toronto's zoning reforms have made sixplexes one of the most attractive multiplex formats for investors and owner-builders. Depending on the lot, a sixplex may be permitted as-of-right or require minor variances through the Committee of Adjustment. Green Street Flats handles the full approvals process — including COA hearings and TLAB appeals when needed — so you don't have to navigate it alone. We have a 100% approval rate on every project we've taken on.
Sixplexes with five or more units qualify for CMHC MLI Select — Canada's best rental financing program. This means up to 50-year amortization periods and interest rates well below conventional mortgage products. Adding a garden suite to reach seven units further strengthens your application. We design every sixplex to qualify for MLI Select from day one and have direct relationships with experienced lenders.
Sixplex construction costs vary depending on lot conditions, unit sizes, and finishes, but a Toronto sixplex typically falls within the low-rise wood-frame construction category — keeping building costs manageable relative to larger concrete-and-steel multiplexes. We provide detailed cost estimates during our free feasibility assessment so you know exactly what to expect before committing.
The ideal sixplex unit mix depends on your neighbourhood and target tenant demographic. Flexible configurations — from studios and one-bedrooms to family-sized three-bedroom suites — allow you to diversify your tenant base and hedge vacancy risk. Six revenue streams on a single lot means stronger cash flow than a fourplex or triplex, with the flexibility to target the rental rates that make the most sense for your market.
Green Street Flats has designed and built sixplexes across Toronto's most desirable neighbourhoods, including Seaton Village, the Annex, and Little Italy. We handle every stage of the sixplex development process — from initial feasibility and architectural design through to zoning approvals, building permits, construction management, and final occupancy. Our sixplexes are designed with an owner's mindset: maximizing rental income and creating buildings that attract quality tenants.
