Recent violent coyote encounters in Greater Toronto Area suburbs, including attacks on children in Whitby and Markham, Ontario, have raised concerns among residents and wildlife experts. Data from Toronto shows that between 2019 and June 2025, there were 20 human injuries caused by coyotes, with nine biting incidents. Dennis Murray, a biology professor at Trent University, suggests that coyote aggression is linked to habituation due to urban living and food-seeking behaviors, and recommends quick action when aggressive behavior is identified. However, Toronto’s city officials continue to follow a coexistence strategy, prioritizing long-term prevention, public education, and aversion tactics over lethal removal.

Violent coyote encounters across the Greater Toronto Area have left some residents on edge and sparked debate among wildlife experts on municipalities’ responses to aggressive animals.

encounters → leave → animals
Increased coyote sightings and a string of attacks on children in the Toronto area in recent months raised alarms and questions about encounters with the wild canines.
asserted
sightings → raise → canines
In July, a coyote approached a toddler at a playground in Whitby, Ont., and bit him on the face, just weeks after another child was hurt in a coyote attack in one of the town’s public fields.
asserted
child → approach → fields
These incidents followed separate coyote attacks on a child and a teenager in Markham, Ont., in May.
uncertain
incidents → follow → May
In Toronto, data from the city shows coyotes carried out 20 attacks on humans that caused injuries, including nine biting incidents, between 2019 and June of this year.
asserted
that → show → year
Dennis Murray, a professor of biology at Trent University, said coyotes mainly act aggressively to protect their dens and pups.
asserted
coyotes → say → dens
“It’s just trying to tell people, ‘Back off, get out of here, we own the space while we’re raising our young in that area,’” he said in an interview.
asserted
he → try → interview
But Murray said coyotes are also becoming aggressive and predatory toward humans due to habituation as they seek food in urban areas – and are even fed by some people.
asserted
they → say → people
“(A coyote) loses its fear of humans, and then as it gets hungry, perhaps it … is testing to see if the child could be prey,” he said.
uncertain
he → lose → humans
Murray said predatory behaviour is “largely irreversible” in coyotes, so municipalities need to act quickly when they identify the animals responsible for attacks on pets or humans.
asserted
they → say → pets
Lethal removal or euthanasia should be considered in such cases before it’s too late, he said, unless it turns out that the coyote is just defending its den site.
asserted
coyote → consider → site
City of Toronto data also shows coyotes attacked or bit 331 dogs from 2019 until June of this year, with 143 such incidents reported across 2024 and 2025.
asserted
incidents → show → 2024
In May 2025, city officials decided to euthanize a pair of mated coyotes believed to be responsible for dozens of attacks on dogs in the Liberty Village and Fort York areas.
uncertain
officials → decide → areas
Murray, who authored an academic paper about those incidents, said his research found that four “problem coyotes” were attacking humans and dogs in both neighbourhoods.
asserted
coyotes → author → neighbourhoods
“We surmised that the municipality was delinquent, frankly, that it should have acted a lot sooner,” he said.
asserted
he → surmise → ?
The city said it continues to investigate and monitor reports of concerning coyote behaviour, and it responds to each case individually.
asserted
it → say → case
Toronto’s coyote management approach is based on a coexistence strategy informed by expertise and research, and it “prioritizes public safety while recognizing that coyotes are an established part of Toronto’s urban ecosystem,” the city said in a statement.
asserted
city → base → statement
The city said long-term prevention, public education and aversion tactics have been effective in mitigating coyote encounters, calling removal of the wild canines ineffective, costly and counterproductive.
asserted
prevention → say → canines
East of Toronto, Whitby’s supervisor of bylaw and animal services said the town euthanized two coyotes that displayed “concerning and abnormal behaviour” in July, but she couldn’t confirm if either was involved in the reported attacks on children.
asserted
either → say → children
“The town is committed to supporting a safe community where residents can coexist with wildlife,” Kate Novia wrote in a statement, noting that Whitby has a “graduated approach, with the level of response increasing based on observed behaviour and potential risk to public safety.”
asserted
level → commit → safety
Novia said the town has received more than 800 reports of coyote sightings since January, almost three times higher than what was reported during the same period last year.
asserted
what → say → period
But that surge isn’t reflective of the number of coyotes in Whitby, she said, citing the town’s communications on the topic as a reason behind the sharp increase in reporting.
asserted
she → say → reporting
North of Toronto in Markham, where a child and a youth were attacked in May, the city said it received a higher-than-usual number of coyote sighting reports this year.
uncertain
it → attack → reports
The city said it has lethally removed coyotes that showed “unprecedented and abnormal behaviour,” but did not specify how many were killed.
asserted
many → say → behaviour
Tiziana A. Gelmi Candusso, a Toronto-based spatial ecologist, said getting rid of coyotes is a temporary solution because they are quickly replaced.
asserted
they → base → coyotes
“It will appease people for a little bit, maybe create controversy, but it will not fix the problem, because we’re having this recurrent issue and it’s always in the same areas,” she said.
asserted
she → appease → areas
A better solution is to change human behaviours that trigger coyotes, and that means keeping dogs on a leash all the time and not feeding wildlife, she said.
asserted
she → change → wildlife
Gelmi Candusso, who built a network of wildlife cameras across Toronto between 2020 and 2022 as part of her post-doctoral research at the University of Toronto, said she isn’t sure the coyote population has increased in the city.
asserted
population → build → city
“The fact that we see more attacks is not necessarily (indicative of) the problem that we have too many coyotes,” she said.
asserted
she → see → coyotes
The problem mainly lies with people who have not yet learned how to coexist with the animals, she said.
asserted
she → lie → animals
Educational programs, including sessions for children and seniors, are key to increasing awareness of how to prevent confrontation with coyotes, Gelmi Candusso said.
asserted
Candusso → include → coyotes
“I would include outreach at schools ... when kids learn something, they also like (to) tell their parents,’” she said.
asserted
she → include → parents
