Large Multiplex Builder
7 to 12+ unit multiplexes that fuse smart design with an owner's focus on durability — creating high-performing rental assets built for long-term value.
Why Build a Large Multiplex
Large multiplexes are where the economics of multiplex development really start to compound. More units on the same lot means lower per-unit land cost, better financing, and a diversified income stream that performs through any market.
Two Ways to Work With Us
Large multiplex projects need the right partner from the start. Choose the path that matches where you are.
You own the land
We handle everything from feasibility and zoning strategy through architectural design, approvals, and construction oversight. You keep ownership — we deliver a finished, income-producing building.

You have approvals and plans. We manage the build — scheduling, trades, quality control, budget management — with the precision of a builder who owns and operates their own multiplexes.

Tenant Strategy
Large sites often come with existing tenants. We handle the N13 process, relocation negotiations, and LTB hearings with the sensitivity and legal precision required to keep your project moving forward while treating tenants fairly.
Our Large Multiplex Approach
We bring an owner's mindset to every large multiplex — focusing on performance, tenant satisfaction, and seamless neighbourhood fit.
Strategically designed shared spaces — from bike storage to entryways — that enhance community without compromising privacy.
Data-driven layouts from studios to family-sized units that cater to key demographics and maximize rental yield across 7-12+ suites.
Exterior designs that create impressive identity, enhancing curb appeal and establishing lasting neighbourhood presence.
Material selection guided by our experience as owners — durable, low-maintenance finishes that protect your investment.
Superior soundproofing between units — critical in larger buildings for tenant satisfaction and retention.
Tenant-friendly, durable features designed to reduce turnover and boost long-term occupancy rates.
Featured Large Multiplex Projects
The number of units depends on your lot size, zoning, and neighbourhood context. Toronto's evolving housing framework is increasingly supportive of larger multiplexes, but most 7+ unit projects require approvals through the Committee of Adjustment or rezoning. Green Street Flats handles the full feasibility assessment and approvals process — we'll tell you exactly what's possible on your site before you commit.
Any multiplex with five or more units qualifies for CMHC MLI Select — Canada's best rental financing program. For large multiplexes with 7-12+ units, the benefits are even more impactful: up to 50-year amortization, preferred interest rates, and financing terms that make projects work that wouldn't pencil with conventional mortgages. We design every large multiplex to qualify for MLI Select from day one.
Large multiplex sites often come with existing tenants. We handle the full N13 process — from notice preparation and relocation negotiations to LTB hearings and timeline coordination with construction. Our approach treats tenants fairly while keeping your project on schedule. This is a critical piece that many developers underestimate.
No. Green Street Flats offers both Development Management and Construction Management for large multiplexes. In DM, we handle everything from in-house architectural design through approvals and construction oversight. In CM, we manage your build with our vetted supply chain. Either way, you get a single point of accountability from start to finish.
We've completed large multiplex projects across Toronto's most desirable neighbourhoods — including 321 St. George (9 units, CoStar Award Winner) in the Annex and 367-369 Howland (10 units) in The Annex. Current projects in development include 14 Grange Avenue (12 units) and 501 Palmerston (9 units). All of our projects are now 7+ units — it's where the company is focused.
