Water infrastructure construction projects in Canada

Canada is committed to heavy investment in infrastructure to stimulate the economy following the impacts of Covid-19. This, coupled with increased investment in water infrastructure in recent years as Canada pushes to implement secondary and tertiary treatment for wastewater, means that we expect lots of activity in this sector. This article is your definitive guide to Canada’s ongoing and upcoming water infrastructure construction projects. Between water supply, water treatment, wastewater treatment, conveyance, flood infrastructure, hydroelectric dams, and ports and marine, we outline the major water infrastructure projects across Canada.

Below is a guide of active water infrastructure construction projects in Canada, categorized in terms of preconstruction or project delivery phase.
