The most telling detail in Toronto's latest rental groundbreaking isn't the loan size. It is the address across the street.
Osmington Gerofsky Development and WJ Properties have formally broken ground on a 38-storey, 474-unit rental tower at 9 St. Dennis Drive in Flemingdon Park, opposite the future Flemingdon Park station on the Ontario Line.[1] The project is backed by $185 million in construction financing from CMHC's Apartment Construction Loan Program (ACLP). It is the first of three phases in a planned redevelopment of roughly 2,300 units on a site the Weinbaum family has owned for more than 60 years.[1]
Phasing is the strategy
A 2,300-unit master plan does not get financed as one project. It gets financed one tower at a time, and the first tower carries the heaviest burden: it must prove rents, absorption and construction costs before the later phases can be underwritten with confidence.
That's why the first phase's capital stack matters. Low-cost, long-amortization federal construction debt lowers the carrying cost of a building that will take years to deliver and then lease up. It reduces the equity needed to start and leaves the sponsor more room to absorb a slow lease-up without forcing a sale or refinancing at a bad moment. If phase one works, phases two and three are underwritten against actual numbers rather than projections.
The first tower includes 95 affordable units, about 20% of the total, along with new parkland and pedestrian connections.[1] Commitments like these are typically part of how projects qualify for federal construction programs. They also make the building's rent roll more resilient by serving renters who have fewer alternatives.
Why transit changes the calculation
Transit-oriented rental housing makes a specific trade. The owner gives up some short-term certainty, because the station isn't open yet, in exchange for long-term demand from tenants who want to live near rapid transit without owning a car.
In a softer leasing market, that trade looks different from how it looked in 2022. Toronto's purpose-built vacancy reached 3.0% in CMHC's 2025 survey, the first reading at that level since the pandemic, and newer, higher-priced buildings felt the most competition from condo rentals.[2] A tower delivering into a crowded market without a clear advantage carries real lease-up risk. A tower beside a future rapid transit station has an advantage that condo investors in car-dependent locations can't easily match.
The timing works too. Construction of a tower this size runs several years, and the Ontario Line itself is still being built. A project breaking ground now is likely to finish closer to the line's opening than one that waits.
Building for operating costs, not just rents
The project also stands out for its mechanical design. Geothermal drilling began in May, with 99 boreholes planned for heating and cooling. The developers expect energy use about 60% lower and greenhouse gas emissions about 80% lower than a conventional code-built building.[1]
For a long-term rental owner, that is an operating-cost decision as much as an environmental one. Utilities are one of the largest controllable expenses in a rental building, and ownership that plans to hold the asset for decades captures the savings. Energy performance also earns points under CMHC's financing programs, which can lower borrowing costs.
What other projects can learn
Not every site has a 60-year owner, a master-planned scale or a station across the street. The Flemingdon Park model still offers principles that apply across Ontario:
- Phase large sites to de-risk later financing. Prove the first building before committing the rest.
- Match long-duration debt to long-duration assets. Rental buildings take years to stabilize, and short-term construction debt adds refinancing risk.
- Locate near durable demand. Transit, hospitals, universities and major employers support absorption better than a tight condo-style floorplan.
- Treat affordability and efficiency as structural features. Both can improve financing terms and lower tenant turnover.
Toronto needs rental supply that pencils under current construction costs and interest rates. Flemingdon Park shows one way to do it: phased, transit-adjacent, financed for the long term and built to keep operating costs down.
