Part of a popular trail in northwest Mississauga will be closed to the public for about a year to allow for the first-ever dredging of a stormwater pond built some 30 years ago.
Osprey Marsh, located to the immediate northeast of Britannia Road West and Ninth Line, was built in the mid-1990s and is now slated to undergo its first dredging to allow it to better perform its important function, the city councillor for the area says.
Preparation work is expected to begin this month with the dredging to begin in October and continue until fall 2026, Ward 10 Coun. Sue McFadden said in her latest newsletter to the community.
To allow the work to be completed, the north section of the Osprey Marsh trail will be closed “for the duration of the project,” beginning in October and continuing until late next year.
“Initially, the closure will occur from Osprey Boulevard (west side of the creek) to the trail access at Lisgar Drive and Pondview Way,” McFadden said. “When phase two begins in spring 2026, this trail closure will extend westerly to Ninth Line. At that time, the east section of the trail from Osprey Boulevard to the three-way intersection heading toward Britannia Road will also be closed to accommodate a separate project — the construction of a fourth Lisgar pumping station.”

McFadden said in her monthly newsletter to constituents that Osprey Marsh is a man-made stormwater pond (or series of smaller ponds) that regulates the flow of rainwater and snow melt from storm sewers and the Sixteen Mile Creek upstream.
“Over time, sediment can accumulate at the base of the pond, reducing its capacity,” the councillor continued, adding this marks the first time Osprey Marsh has been dredged since it was built three decades ago.
“In order to comply with environmental regulations, the project will extend over multiple phases, starting with the drying of the northeast part of the pond in late October through December. Water will remain in the rest of the marsh and dredging of those sections will occur by barge, with sediment being stored temporarily on the dry section established in the first phase.”
Osprey Marsh, much like nearby Lake Wabukayne to the east, has also become home to numerous types of birds and other wildlife over the years.
