Toronto’s recently expanded multiplex housing opportunities have given rise to a builder focused on speed and scale. Modcity has quickly become one of Toronto’s most active fourplex developers, with 27 infill projects underway across established neighbourhoods — each featuring a garden or laneway suite as a fifth unit. Founded in 2022 when the company’s trio of founders saw opportunity in Toronto’s changing planning landscape, Modcity says it is already delivering spacious, family-oriented rentals at a pace rarely seen in the sector.
Anticipating the passage of the City’s 2023 Multiplex By-law, partners Ron Sheinin, Crane Liu, and Rohan Sadana combined backgrounds in custom homebuilding, investment banking, and private equity to create a company designed for efficiency and repeatable results. Together, they gathered a team of 11 professionals and advisors with expertise across development, construction management, and acquisitions. Their shared aim is to scale a model that delivers family-sized rental housing in established neighbourhoods, pairing private-sector precision with the responsiveness of small-scale infill.
The company’s approach is a standardized, design-build system that compresses the development cycle from years, with each project moving from acquisition to permits in roughly five months, including Committee of Adjustment approvals, followed by about ten months of construction and leasing. This fifteen-month turnaround contrasts with the five- to ten-year timelines typical of larger buildings. Managing every stage from site acquisition to construction, financing, and tenant move-in, the company applies consistent design and construction methods across all projects.
Among Modcity’s growing portfolio, projects near Caledonia and Fairbank stations on the soon-to-open Eglinton Line 5, are completed and leased fourplexes that demonstrate the firm’s focus on efficient layouts and modern infill architecture. Their Leaside development, now in the framing stage, stands out for receiving 105 signed letters of support from nearby homeowners during its Committee of Adjustment process – unprecedented for a fourplex in Toronto.
At Bloor and Ossington, construction started in October, 2025 for the Christie Pits Rowplex that combines three severed parcels into a single coordinated build, forming Toronto’s first triple-fourplex with twelve large three-bedroom suites. Across the designs, the emphasis is on open-concept kitchens built for families, dedicated children’s rooms, flexible home office space, and spacious primary bedrooms with ensuites.
Since the Multiplex By-law took effect, Modcity has completed six new-build projects, with another seven under construction, and fourteen in permitting. Supported by more than $18 million in raised equity and an as-complete asset value exceeding $100 million, its active portfolio represents roughly three times the volume of its closest competitors. Every building is composed entirely of three-bedroom suites, with standardized plans ranging from 1,000 to 1,300 ft², aiming to fill a gap left by high-rise developments.
Beyond its construction activity, the company has taken on a visible role in Toronto’s housing conversation. It has hosted tours for City Councillors, Deputy Mayors, Provincial representatives, and senior City Planning staff to showcase completed projects and demonstrate the practicality of infill multiplex housing. Its leadership frequently participates in Planning and Housing Committee meetings, advocating for policies that expand low-rise rental options and streamline approvals.
With a goal of 100 fourplex and garden-suite projects by 2030, Modcity is positioning its model as a key part of Toronto’s changing housing mix. Its approach offers a blueprint for how private builders can help expand the city’s missing middle, one infill site at a time.
