Ontario is home to eight species of freshwater turtles, all of which are listed as at-risk. Turtles have lost over 70% of the wetlands they call home in southern Ontario due to commercial development. Turtles being killed on our roads, which often slice through their remaining habitat, is another leading threat to ever-declining turtle populations (see below for more details).
Working with data from the Ontario Turtle Conservation Centre (OTCC), we identified the top six towns with the greatest number of road casualties for freshwater turtles in the province. Click here to explore.
Earthroots needs your help to convince municipalities to install wildlife underpasses along high-risk roads to reduce turtle mortality. Turtle crossing signs are not enough. Turtles have dark shells and are hard to see on dark pavement. Without proper underpasses, turtles will continue to be hit and killed by speeding vehicles.

Dear Mayor/Reeve (name)
I am writing to inform you that your town has one of the highest turtle mortality rates in Ontario and request that you act to stop these avoidable deaths.
All eight species of freshwater turtles in Ontario are listed as at-risk. Road mortality is one of the leading causes of turtle population decline in the province. Your town has been identified by data from the Ontario Turtle Conservation Centre (OTCC) as one of the six highest risk areas for turtles in Ontario.
As a result, I request that you install wildlife underpasses during the next road upgrade. To learn more about the specific location that needs attention, please contact Rebecca Kolarich, Earthroots' Protected Spaces Specialist, at firstname.lastname@example.org.
Turtles in your community, who are listed as at-risk species, need your help. Please improve the safe passage of turtles across roads and give our incredible turtles the chance to recover.
Thank you for your time,
Mayor of Scugog: Bobbie Drew, email@example.com
Reeve of Kaladar: Henry Hogg, firstname.lastname@example.org
Mayor of Port Severn (Georgian Bay): Peter Koetsier, email@example.com
Mayor of Gravenhurst: Paul Kelly, firstname.lastname@example.org
Mayor of Apsley (North Kawartha): Carolyn Amyotte, email@example.com
Mayor of Peterborough: Diane Therrien, firstname.lastname@example.org
Road mortality is one of the leading causes of turtle population declines. Roads pose a double threat to our turtles:
Working with data from the Ontario Turtle Conservation Centre (OTCC), we identified the top 20 towns with the most roadway turtle casualties, including the six areas with the deadliest roads for freshwater turtles in the province.
Earthroots is calling on these municipalities to mitigate turtle road mortality with the installation of wildlife underpasses along high-risk roads. We will be working with municipal councils to bring light to this issue and request the installation of wildlife underpasses in each of the highlighted areas in the map above. You can help us by sending letters to Municipal leaders (see above.)
This table is based on turtle road casualty data from the OTCC from 2015 to 2021 which was collected from volunteers and OTCC staff members engaged in helping injured turtles on Ontario roads. As a result, the number of turtle road casualties recorded in a specific location is affected by the availability and interest of local volunteers as well as any local road conditions hazardous to turtles.
In 2016, The Haliburton Highlands Land Trust completed their first turtle road mortality mitigation project. The Land Trust selected sites where there had been many sightings (100+) of turtles along and/or adjacent to busy roadways and installed barrier walls along existing culverts for an approximate cost of $35,000. Results were positive, turtles were unable to access the roads and after two years of monitoring, 60+ turtles were documented making successful passages.
Based on these results it has been concluded that the barrier wall, together with the culvert underpass, is a successful, cost-effective mitigation technique for reducing turtle road mortality.
Ontario Turtle Conservation Centre, home of Kawartha Turtle Trauma Centre, is a registered charity whose goal is to protect and conserve Ontario’s native turtles and the habitat in which they live. To learn more visit ontarioturtle.ca.
