Toronto’s skyline is set to evolve dramatically as Pinnacle International unveils a bold new redesign for the South Block of One Yonge, transitioning from its original office-heavy concept into an ambitious dual towers mixed-use high-rise proposal. This revamp aims to better align with shifting market demand, putting residential, retail, community, and public realm uses front and center in place of outdated office space. With two towers soaring to 80 and 85 storeys, the project promises to deliver over 2,400 homes, activated streetscapes, and improved connectivity at a pivotal waterfront juncture.
This redevelopment marks one of the most significant reconfigurations in Toronto’s ongoing waterfront transformation. For CondoTrend’s readers, here’s everything to know — from design changes and community impact to developer strategy and what it signals for downtown real estate.
Evolution of One Yonge & Project Context
The One Yonge master plan dual towers have long stood as a landmark proposal at the foot of Yonge Street, bridging the business core and Toronto’s lakefront. The project encompasses multiple phases, including residential towers, public realm improvements, retail podiums, and the recladding of the existing Toronto Star building.
Originally, the South Block was slated to emphasize office and commercial space. But with office demand under pressure in the post-pandemic era, Pinnacle’s redesign redirects focus to residential and mixed-use components. The pivot underscores how developers are rethinking downtown product mixes to match evolving preferences.
Design Highlights & Program Mix
At the core of the redesign are dual towers rising to 80 and 85 storeys. The scheme features:
- 2,406 residential units, spanning various unit types to attract a diverse demographic.
- Integrated retail, community, and public spaces on lower podium levels to energize the street.
- Conversion of previously office-intended space into amenity, indoor/outdoor recreation, and experiential uses.
- Creation of active transportation infrastructure, widened sidewalks, and mid-block pedestrian connections.
- Upgrades to public realm and “place-making” elements that weave the towers into Toronto’s urban fabric.
By redistributing square footage from offices to residences, the project addresses pent-up housing demand in downtown Toronto. It also anticipates future flexibility: should office trends rebound, spaces could be adapted.
Implications for the Downtown Real Estate Market
This redesign of dual towers is emblematic of a broader trend: office-to-residential conversions and mixed-use pivots. The downtown Toronto market has seen softened demand for pure office space, especially at lower A-office class levels. The One Yonge conversion signals how large-scale developers are hedging by introducing more resilient residential product into high-profile plots.
For the investor and condo market, the implications are substantial:
- Supply shift: over 2,400 new units in the heart of the waterfront will influence condo absorption rates and pricing dynamics.
- Location premium: these residences come with built-in transit, walkability, and waterfront proximity — features commanding premium pricing.
- Risk mitigation: diversified use (residential + retail + public realm) helps buffer the project against fluctuations in any single sector.
As taller mixed-use buildings gain favor, we may see similar proposals across Toronto, Vancouver, and other growth markets — especially where land value near transit is high.
Connectivity, Public Realm & Urban Integration
Connectivity and the public realm are central to the South Block’s redesign:
- Through-block pedestrian routes and widened sidewalks will help stitch the towers into surrounding blocks.
- The proposal emphasizes active transport by boosting cycling links and pedestrian accessibility to transit nodes.
- The design rethinks how podiums meet the street — ideally activating frontage with retail, cafés, and community functions.
- Integration with the existing Toronto Star building and legacy elements ensures continuity across architectural epochs within the block.
This contextual sensitivity and emphasis on public life aim to mitigate what often feels like “luxury towers dropped into a cityscape” — here, the goal is coexistence, not isolation.

What’s Next & Potential Challenges
Though conceptually compelling, the project faces several hurdles:
- Zoning & approval processes: the designs will need city planning, design review, and council approvals — with potential for tweaks and community input.
- Phasing & market timing: delivering such a large-scale project in phases will require careful sequencing, ensuring early phases don’t stall amid market swings.
- Construction cost & materials: high-rise mixed-use towers come with premium structural demands and facade systems that are cost sensitive.
- Retail leasing and activation: to truly activate the street, securing compelling tenants that suit local demand will be essential.
If these challenges are managed well, the South Block redesign could become a benchmark development in dense urban waterfront contexts.
Final Thoughts
The reimagined South Block of One Yonge marks a pivotal moment in Toronto’s waterfront evolution. By shifting away from a primarily office-centric model to a vibrant, mixed-use, residential-first vision, Pinnacle is betting on a future where downtown life embraces live-work-play integration at all scales. With over 2,400 residential units, thoughtful activation of ground levels, pedestrian enhancements, and a stronger public realm, this project has the potential to reshape how high-density towers are introduced in established city cores.
For CondoTrend’s audience, this is more than just a design announcement, it’s a directional signal for what the next generation of Toronto high-rise living might look like. It highlights how developers are responding to market headwinds, how transit adjacency continues to command value, and how purpose-driven public space can elevate major developments. If approved and executed, the South Block redesign may well become a case study in how to balance density, livability, and market adaptability in one of Canada’s densest urban nodes.
As approval and construction unfold, we’ll keep watching how unit pricing, absorption pacing, and street-level lease-up evolve. For now, one thing is clear: the future of Toronto’s waterfront is edging ever closer to this bold new skyline chapter with these dual towers.
