Why You Should Attend The Toronto Sustainabilty & Innovation Summit

Why This Matters:

The viability of Toronto’s net zero pathway is being decided by what happens to existing buildings, and what gets built next. Existing buildings are the city’s largest source of greenhouse gas emissions at 55 percent, and owners are moving into a tighter measurement environment through annual energy and water reporting requirements that also intersect with Ontario’s large building reporting framework. At the same time, new construction and major redevelopments face a higher bar on upfront carbon through Toronto Green Standard v4 embodied emissions intensity thresholds, while Ontario’s building code has expanded options by allowing 18 storey encapsulated mass timber construction. Join the largest property owners in the region as they outline what is coming next in sustainable building. 

What You’ll Learn:

  • How Toronto owners are prioritizing deep retrofits in office, multifamily, and institutional assets, including what scopes move the needle and how to phase work in occupied buildings.

  • Which sustainable construction and design innovations are becoming more feasible in Toronto now, including the implications of Ontario’s mass timber allowance for mid and high rise delivery.

  • How to use required energy and water reporting to benchmark assets, set internal targets, and build a multi year capex plan that aligns with renewal cycles.

  • What procurement and contracting approaches are helping teams hit performance targets, manage schedule risk, and control cost volatility while meeting stricter design requirements.

  • How design teams are approaching embodied carbon requirements under Toronto Green Standard v4 and what that changes in early decisions on structure, envelope, and procurement.

How You’ll Do More Business:
Enhance your business by understanding how Toronto owners and developers are selecting partners for retrofit scopes and future ready new builds as performance expectations tighten. Hear directly how decision makers are prioritizing projects, what qualifies a firm to make the shortlist, and how teams are aligning design, constructability, and cost control to deliver measurable outcomes in Toronto.

Who Attends:
Toronto’s policy makers and city officials, owners and operators, developers and builders, investors and lenders, architects and engineers, sustainability and ESG leads, construction managers, technology and building systems providers, consultants and advisors.

Why You Should Attend
This event brings together Toronto’s key decision-makers across the built environment to share what’s happening now and what’s next in sustainability and innovation, so you can build relationships, sharpen your strategy, and uncover new opportunities across both existing building upgrades and next-generation development.
