Construction is one of the most important economic sectors in Canada, generating more than $150 billion in GDP in 2022. Simultaneously, Canada’s construction sector generates more than 4 million tonnes of waste per year – with much of the value from these waste materials and resources currently being lost from Canada’s economy at end of life.


A circular built environment for Canada can generate multiple benefits, including reducing waste and greenhouse gas emissions; improving the resiliency of supply chains; creating new economic, investment, and employment opportunities; enhancing natural ecosystems and urban green spaces; and providing greater equity and related social benefits.


CELC’s Circular Built Environment work stream goes beyond a focus on construction waste to encompass the entire built environment and real estate ecosystem in Canada, linking existing efforts together and going deeper on emerging topics that require further research and investigation. This work stream seeks to better define the business case for advancing the circular built environment in Canada to encourage further investment and innovation, including in circular design, material innovation, deconstruction and resource recovery, critical infrastructure, improved information and data (including on embodied carbon of products and materials), and procurement.

Recent projects and ongoing initiatives are exploring the business case for extending the life of existing buildings, the policies and standards needed to support circularity in the construction sector, and are working with industry to develop a roadmap and launch a Circular Construction Innovation Hub inline with the recently published strategic framework for action.
