Toronto Missing-Middle Development

One house in.
Six homes out.

We replace Toronto's tired houses with brand-new, energy-efficient six-unit family rental buildings — in the nine wards where the city now allows it as-of-right.

The Opportunity

The missing middle

Toronto quietly made its biggest zoning change in generations: six rental units, as-of-right, on regular residential lots in nine wards. No rezoning required. Development charges waived for qualifying projects.

Families priced out of buying want to live in these neighbourhoods — The Beaches, Danforth Village, Leslieville, East York — yet almost no family-sized rental supply exists. That gap is our work.

What We Build

Family-sized homes, not condo boxes

Six self-contained homes in one new building — full-floor three-bedrooms, bright family two-beds, one fully accessible home and one attainable home — with the space, light and storage a condo can't offer.

Full-floor 3-bedrooms

An entire floor for one family — the unit type nobody builds and the market pays the biggest premium for.

Bright family 2-beds

Compact, light-filled, well-planned.

Six homes, one building

Including one accessible and one attainable home — the design is the financing.

Concept renderings — illustrative of our design approach.

The Engine

Every decision runs on evidence

Behind every acquisition is a proprietary underwriting engine — AI-assisted analysis, human-verified decisions, and a discipline most buyers can't match.

01

Closed data, not asking prices

We track thousands of closed leases and sales across 18 MLS districts — refreshed monthly. Rents are underwritten against what tenants actually signed, never what landlords hoped.

02

A maximum bid for every lot

Every ward and every property gets its own printed ceiling from the buy box — finished value, build cost, financing, all solved before we offer. When a property goes over our number, someone else owns it.

03

Financing engineered in

Projects are designed to CMHC MLI Select's 100+ point tier from the first sketch — energy and affordability built in, unlocking the strongest rental-housing financing in Canada.

Our Work

Real builds, not just renderings

Our delivery team has completed eight CMHC multiplex builds, with an in-house MLI Select energy practice and a construction partner four decades deep — on-budget, on-schedule, on fixed-price contracts.

Our Approach

How we build

01 — Buy

The right lot

Tired houses on the right frontage in the nine wards — bought below finished value against a strict, printed maximum bid.

02 — Build

Six new homes

One energy-efficient building, delivered by our partner team on a fixed-price contract.

03 — Finance

Designed for CMHC

MLI Select 100+ points by design — the strongest long-term financing in Canadian rental housing.

04 — Hold

For decades

We lease and manage our own buildings — durable, well-located assets, held long-term.

We don't build glass boxes. We build the homes families actually want to live in.
