A surge of coyote attacks targeting children and pets across the Greater Toronto Area has sparked a heated debate among wildlife experts and city officials. Recent violent encounters in Whitby and Markham have forced municipalities to choose between lethal removal and long-term coexistence strategies.
The 331 dog attacks signaling a shift in Toronto's urban wildlife
Data from the City of Toronto reveals a troubling trend in human-wildlife conflict, with 331 dogs attacked or bitten by coyotes between 2019 and June of this year. According to the report, 143 of those canine incidents occurred specifically within the 2024 and 2025 window, suggesting an escalation in aggression. Human casualties are also a factor, with 20 reported injuries to people, including nine biting incidents, during the same period.
This trend reflects a broader struggle in North American urban centers where wildlife habituation is becoming common. When animals lose their natural fear of humans, the boundary between coexistence and predation blurs,turning public parks into high-risk zones for small children and pets.
Why Toronto euthanized mated coyotes in Liberty Village and Fort York
In May 2025, Toronto city officials departed from their usual non-lethal stance to euthanize a pair of mated coyotes believed to be responsible for dozens of dog attacks in the Liberty Village and Fort York areas. This move came amid criticism from Dennis Murray, a biology professor at Trent University, who argued that the municipality was "delinquent" and should have acted much sooner to protect the public.
Professor Murray's research indicates that four specific problem coyotes were targeting humans and dogs in those neighborhoods. he contends that once a coyote develops predatory behavior toward humans—often triggered by being fed or seeking urban food sources—the behavior is largely irreversible , making lethal removal the only viable safety measure.
Tiziana A. Gelmi Candusso's argument against lethal removal
Contrasting the call for euthanasia, Tiziana A. Gelmi Candusso, a spatial ecologist based in Toronto, argues that killing individual animals is merely a temporary fix.. Based on her post-doctoral research at the University of Toronto, which included a network of wildlife cameras from 2020 to 2022, Gelmi Candusso suggests that removed coyotes are quickly replaced by others, meaning the root cause remains unaddressed.
As reported, Gelmi Candusso believes the primary issue is not an increase in the coyote population, but rather a failure in human behavior. She advocates for strict leash laws and the total cessation of feeding wildlife, suggesting that educational outreach in schools is the most effective way to change how parents and children interact with urban predators.
Whitby's 800 sightings and the mystery of the July attacks
The crisis has extended east to Whitby, where the town has recorded over 800 coyote sightings since January—nearly triple the volume reported during the same period last year. This spike in reports coincides with harrowing incidents in July,including a toddler who was bitten on the face at a playground and another child injured in a public field.
Despite the violence of these attacks, several critical questions remain unanswered. Kate Novia, Whitby's supervisor of bylaw and animal services, stated that while two coyotes were euthanized in July for abnormal behavior, she could not confirm if those specific animals were the ones that attacked the children. Similarly, while the city of Markham confirmed it has lethally removed coyotes following attacks on a child and a teenager in May, it has not disclosed exactly how many animals were killed.
