The reported sightings prompted McFadden to declare she and City of Mississauga staff were going to keep a close eye on the situation as they searched for a better solution.<\/p>\n
\u201cAdditional attention is being paid to this matter in the coming weeks,\u201d the councillor told constituents at the time.<\/p>\n

Fast-forward to earlier this week when McFadden told residents in her latest update that beavers, among the largest living rodents in the world, \u201ccontinue to reside along the Sixteen Mile Creek running through Lisgar.<\/p>\n
\u201cDespite previous efforts last winter to remove several beavers, another lodge and series of dams have been spotted further north within the tributary,\u201d McFadden continued. \u201cI have met with (City of Mississauga) staff on several occasions to develop short- and long-term plans to ensure that the beaver activity is not negatively impacting the stormwater system in this area.\u201d<\/p>\n

McFadden said she\u2019ll also host a townhall meeting, tentatively scheduled for Dec. 2, as her office continues to receive \u201congoing messages of concern from the community.\u201d<\/p>\n
She noted the public meeting will specifically address \u201cthe topic of managing beavers within an urban setting,\u201d adding city staff will present the municipality\u2019s policies and operations, as well as Ontario government regulations they must adhere to.<\/p>\n
\u201cWe\u2019ll share what the current situation is in Lisgar and how our office and staff have been working to address it,\u201d said McFadden, adding officials will also take questions and comments from residents at the meeting.<\/p>\n

Osprey Marsh, located to the immediate northeast of Britannia Road West and Ninth Line, 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.<\/p>\n
Essentially, it\u2019s an important feature that\u2019s designed to control flooding, which has impacted that part of Mississauga for years.<\/p>\n
McFadden said late last fall that her office worked closely with city staff to address \u201cthe recent situation of stagnant water\u201d along the creek that was supposed to drain into Osprey Marsh.<\/p>\n
\u201cSo far, two beaver dams have been removed \u2014 one south of the Osprey Boulevard bridge and one just north of it,\u201d the councillor said in late 2025. \u201cReports of additional dams further upstream have been investigated and two more have been confirmed and will be removed shortly to restore proper flow and level of water in the creek. Relocation of the beavers to a more rural setting is also being considered in order to help manage proper operation of the stormwater system in the Lisgar community.\u201d<\/p>\n

The issue with the beavers continues as Osprey Marsh is undergoing its first-ever dredging<\/a> to allow it to better perform its important function, the city said earlier.<\/p>\n The marsh\/stormwater pond was built in the mid-1990s and the ongoing work this year will remove sediment that has settled at the bottom of the pond the past few decades.<\/p>\n The work is expected to be completed by the end of this year<\/a>.<\/p>\n 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.<\/p>\n And this isn\u2019t the first time the thick-furred, web-footed beavers have left an unwelcome mark on the site.<\/p>\n
