On Sunday, approximately 30 ducks and one heron were found dead at Woodbine Beach.
According to the City of Toronto, Animal Services has removed the animals and will be conducting testing to determine the cause of death.
The testing may take up to two weeks for test results to come back.
The City reports that the ducks were found near an off-leash area and that dogs were also seen near the ducks.

Dog owners are being asked to ensure that all dogs are leashed in Woodbine Park, including in the off-leash area, until the cause of death has been determined.
Anyone who was in the area on Sunday with their dogs is asked to check with their vets if the pups are experiencing signs of illness.
