About the event

Join us as we explore Towards Steel Circularity:Transforming the Market through Policy Initiatives through an engaging panel discussion with a group of forward-thinking policymakers, developers, and technical experts.

You’ll gain insights into the latest market drivers around the adoption of reused steel and understand the advantages of doing so from a building owner’s point of view. Whether you're a developer, policymaker, architect, engineer, or simply curious about reused steel as a structural material, this event offers an insightful exploration of the evolving effort around material circularity in modern construction.

Hosted as a collaboration between CLF Toronto and WSP Canada, the event will be held in-person at WSP’s Toronto office located at

Unit 700- 25 York Street,Toronto, Ontario (Press 7 on the Elevator Tablets in the Lobby)

Doors open at 5:00pm, event starts promptly at 5:30pm.


Antoni Paleshi, P. Eng, MASc,

Technical Lead, Energy & Carbon Analysis


Antoni Paleshi is a national practice leader for the decarbonization of buildings in WSP Canada’s Climate Change, Resilience and Sustainability team, with 20 years of experience in the field. Antoni specializes in the design, simulation and evaluation of building efficiency and GHG reduction measures with experience leading teams towards zero carbon buildings in all major sectors. Antoni has also lead and is leading a number of policy- community- and portfolio-scale building decarbonization projects for organizations like the City of Vancouver, Toronto Community Housing and Sunnybrook Hospital


Zac Zandona, P.Eng., Project Lead, Environment & Climate Division at City of Toronto

Zac is a Project Lead with the City of Toronto’s Environment and Climate Division. With an engineering background, his work has been focused on decarbonizing new developments through the implementation of the Toronto Green Standard Energy and Emissions requirements for the last 5 years.

Robert Raynor, M.Arch, Net-Zero Coordinator at TAS

Robert is a designer, researcher, maker and amplifier of voices. He holds a Masters of Architecture degree from the University of Toronto, with a background in woodworking, life-cycle analysis and carbon thinking, and community engagement for chronically unhoused populations. In his role as TAS's Net-Zero Coordinator, he oversees the implementation of portfolio-wide decarbonization and circularity practices, identifying the levers developers hold to shape a net-zero world at each stage of the development process. When he's not doing those things, you're most likely to find him in a forest, on his bicycle, or hanging out with cats.

Ryan Zizzo, PEng, MASc., Founder & CEO at Mantle Developments

Ryan is a recognized leader in helping large organizations and governments transition to a low-carbon future. Ryan's work has directly supported an update to the Toronto Green Standard version 4, North America's first policy to limit embodied carbon on certain types of new building construction. He has also contributed to the development of the Government of Canada's Standard on Embodied Carbon in Construction which requires low-carbon concrete on large federal construction projects. Ryan has also worked with leading organizations like the YMCA of Greater Toronto to help quantify and minimize the carbon impacts associated with major construction projects.

Lena Javidiani, Building Science Engineer, Office of Sustainability at Sheridan College

Lena is a seasoned civil engineer with passion for sustainability. Growing up in a family full of Civil Engineers she was exposed to the world of construction and Civil Engineering from a very early age.  After getting her degree from Concordia University in Montreal, she kicked off her career as an engineering assistant in research and development at Flynn Group of Companies, with specialization in building envelope innovation. Over the course of her career she has spent time on various facets of civil engineering including working as a consultant specializing in cold-formed steel design. Currently, as a member of the sustainability infrastructure department at Sheridan College her key focus areas are working towards Sheridan’s framework for institution-wide sustainability initiatives. It is an ambitious mandate to re-envision the College’s energy future, making significant reductions in its institutional footprint, and meet breakthrough performance targets.
