Architectural rendering of the 3377 Bayview Avenue redevelopment showing mid-rise residential buildings, open green space, and community areas with people walking, cycling, and gathering. — Rendering of the proposed redevelopment at 3377 Bayview Avenue, which will include new residential towers, park space, and affordable rental housing in North York.

Toronto’s north end is getting a master-planned community with permanence built in. At 3377 Bayview Avenue—the Tyndale Green redevelopment—City Council has approved $16.32 million in capital funding to secure 102 new affordable rental housing units for 99 years under the Rental Housing Supply Program (RHSP). It’s one of this year’s largest allocations, and it locks long-term affordability into a project that is reshaping an institutional campus into a mixed-income neighbourhood.

From campus to complete community

North York Community Planning has cleared a key milestone: a Draft Plan of Subdivision creating 10 blocks—six residential blocks, two public park blocks, one green space/natural heritage block, and one block retained for Tyndale University. A new 18.5-metre public loop road will enter from Bayview at the site’s north end, curve through the community, and reconnect at Benham Crescent in the south, giving every building a proper public address and safe pedestrian frontage.

The plan protects what matters. The green space/natural heritage block (13.7646 hectares)—lands below top-of-bank within the German Mills Creek ravine system—will be conveyed to TRCA, securing ecological function and trail potential. Two new public parks (Blocks 9 and 10) will front Bayview, with the southern park delivered in Phase 1 and the second park in Phase 2.

What’s being built—and when

The site will build out in two subdivision phases and four construction phases:

Phase 1: Delivers Street A (temporarily cul-de-sac’d), Park Block 9, the TRCA natural heritage block, the Tyndale University block, and Residential Blocks 4 & 5 first—followed by Block 6.
Phase 2: Extends the road network (Streets B & C) to complete the loop, adds Park Block 10, and builds Residential Blocks 1–3.

Across the full build, the approved concept contemplates 1,511 homes. Affordable housing is included in every construction phase, with a total program of 239 affordable units across the entire site (a combination of units secured via the Purpose-Built Rental stream plus 34 in-kind affordable units through the City’s Community Benefits Charges). The Sept 22 editorial spotlights this year’s RHSP-funded tranche—102 units—because that’s the immediate City investment moving the project from concept toward construction.

How the City is making the numbers work

The $16.32M capital grant is delivered as a forgivable loan tied to milestones. The project also qualifies for the City’s ARRCHI incentives—waivers of planning and building fees and exemptions from development charges/parkland cash-in-lieu (where applicable)—plus a property tax exemption on the affordable homes for the full 99-year term. Layered together, these tools help counter high construction and financing costs and keep the project viable without shrinking the affordable program.

Housing, parks, and schools—planning for real life

As density arrives, services need to keep pace. The TDSB advises that AY Jackson SS currently lacks capacity for projected enrolment and Steelesview PS and Zion Heights MS may also be constrained by the time residents move in. As a condition of approval, the developer will include warning clauses in all purchase/lease/tenancy agreements for ten years, noting that portables, boundary changes, program moves, or busing may be used until space is available. It’s a pragmatic step that signals growth planning is happening in the open.

On the mobility side, Transportation and Development Engineering are finalizing details on signal timing at Bayview, stormwater management, and easements; those will be locked in before final subdivision registration. Meanwhile, the loop road design, generous sidewalks, and park frontages aim to make walking the obvious first choice for short trips.

Equity and environmental benefits, built in

Tyndale Green shows how institutional land can deliver mixed-income housing, public parks, and permanent green protection at once. At least 20% of the affordable homes will be offered to residents receiving housing benefits, aligning with the City’s equity goals. The TRCA conveyance preserves a major piece of ravine habitat, and the project is advancing under Toronto Green Standard requirements.

Bottom line

With 102 affordable rental homes funded this year for 99 years, and 239 affordable homes planned across the full site, 3377 Bayview is a cornerstone project in Toronto’s 2025 pipeline. It pairs long-term affordability with new parks, protected ravine lands, and a human-scaled street network—a template for turning legacy campuses into complete communities.
