The Regional Municipality of York is contributing $24 million, and the federal government an additional $16 million, to construct a storm water treatment facility that will reduce runoff from Holland Marsh into Lake Simcoe.

Today, Catherine McKenna, minister of Infrastructure and Communities, Deb Schulte, minister of Seniors and MP for King-Vaughan, Helena Jaczek, MP for Markham-Stouffville, and Wayne Emmerson, York Region chairman and CEO, announced the funding in Willow Beach for the facility that will protect the lake’s watershed from excessive algae growth.

The Lake Simcoe Region Conservation Authority identified the Holland Marsh as a critical point load of phosphorus, contributing an average of six tonnes a year., according to a federal government news release.

The release of excess phosphorus from agriculture, such as fertilizer, places the Lake Simcoe watershed at risk of eutrophication that can irreversibly destroy aquatic habitats and ecosystem biodiversity.

“This project alone will reduce phosphorus runoff into Lake Simcoe by 40 per cent, cutting algae growth in the lake’s watershed, preserving fish habitat and protecting a major source of drinking water. We simply have to invest now in infrastructure that protects Canadians, our environment, and the biodiversity of our ecosystems," McKenna stated.

"The $16 million the government of Canada is investing in this storm water treatment facility will ensure York Region residents have access to quality drinking water, and will preserve industries that are important to the economy, including agriculture and recreation.”

The project is expected to save $5.38 for every dollar invested, according to the federal government.

“Building strong, caring, safe communities is a top priority for York Regional council. This includes building resilient infrastructure for residents today and into the future. Through the support of our federal partners we continue to safeguard the local water supply, while also investing in innovative solutions to protect the Lake Simcoe watershed and its habitats,” Emmerson said.

Lake Simcoe is the largest inland lake in southern Ontario outside of the Great Lakes. The watershed is home to more than 435,000 people.
