beaver at Osprey MarshI am aware that our somewhat cute but not-so-friendly rodents are back again at Osprey Marsh this spring. With no activity in the pond last fall, I hoped that the beavers living there had moved on to find a new home. Whether this is the same beaver or a new one has moved in, we can’t be sure. It’s also quite possible that the new marsh inhabitant is a muskrat. Regardless, the City’s approach to dealing with this kind of rodent remains the same.


My top priority is the protection of the mature trees that encircle the Marsh. I have worked with staff to add netting around the trunks of some trees and chicken wire cages around others to keep the beavers away. In addition, Forestry staff schedule tree plantings at the Marsh regularly to replace the smaller trees and saplings.


Stormwater management staff routinely monitor all watercourses in the city, including Osprey Marsh, to ensure the infrastructure is working property. To date, beaver dams or lodges have not negatively impacted the flow of water at this pond. Staff have removed dams in the past when deemed appropriate. Note that removing or destroying beaver dams is illegal without proper risk assessment by a professional.


The City must comply with provincial legislation in how it manages wildlife. The Fish and Wildlife Conservation Act and the Ministry of Natural Resources and Forestry impose certain regulations that must be followed.


Trapping or relocation of beavers is only done as a last resort – only to ensure public safety, maintain infrastructure and/or for the protection of property. Beavers are native to Ontario and considered part of the natural ecosystem and provide some benefits to wetlands and watersheds.


Beavers are typically not dangerous to humans or pets. However, if you encounter one, keep a safe distance so as to not make it feel threatened. Report injured beavers to Animal Services at 905-896-5858. Report fallen trees impacting trails or watercourses to the City at 311.
