THOROLD, Ontario (UI) — The Ontario government is investing nearly $44 million in water, wastewater and stormwater infrastructure projects across the Niagara Region as municipalities work to modernize aging systems and improve resilience during extreme weather events.

The funding will support multiple infrastructure projects, including stormwater improvements, wastewater treatment plant upgrades and watermain replacement work in four Niagara-area municipalities.

Among the projects receiving funding are a $24.5 million upgrade to the Niagara Falls Wastewater Treatment Plant, a $10.7 million sanitary, water and storm infrastructure renewal project in Welland and a $4.5 million watermain replacement project in Fort Erie. St. Catharines will also receive funding to rehabilitate the Martindale Pond Weir.

Ontario officials said the funding is being delivered through the province’s Municipal Housing Infrastructure Program Health and Safety Water Stream, which supports infrastructure upgrades tied to public safety, housing development and system reliability.

Acting Infrastructure Minister Todd McCarthy said the projects are intended to help communities modernize aging infrastructure while supporting future growth.

“Through our infrastructure program, we are helping communities modernize aging water systems and support long-term growth,” McCarthy said.

Local officials said the projects will improve service reliability, expand capacity and help communities better manage storm-related impacts and future development pressures.

Ontario said the broader infrastructure program has supported upgrades to water, wastewater and stormwater systems across the province since launching in 2024.
