Longueuil obtained provincial authorization in October 2024 to reduce the white-tailed deer population in Michel-Chartrand Park. The permit was valid until mid-February 2025, and the Montreal-area city said a specialized contractor would carry out the operation with air rifles while the park was secured.
Why the city sought a cull
Municipal officials said the herd had grown from 32 deer in 2017 to 114 in 2024, far beyond what the urban park could sustain. Heavy browsing was damaging young trees and understory plants, with consequences for habitat used by other species.
The city also cited vehicle collisions and the potential spread of ticks associated with Lyme disease. Those concerns did not mean that every deer carried disease or that the animals alone determined human infection risk; they formed part of a broader management case.
A long and divisive dispute
Longueuil first announced a cull in 2020. Animal-protection organizations and residents challenged the plan and advocated options such as relocation, fertility control or continued monitoring. Court proceedings delayed the operation but ultimately left the municipality able to proceed.
Opponents argued that killing healthy animals was unnecessary and questioned whether non-lethal alternatives had been exhausted. The city maintained that relocation would create capture and transport risks, suitable release sites were unavailable, and fertility control would not reduce the population quickly enough to protect the park.
How the operation was designed
The permit allowed trained personnel to use high-powered air rifles under controlled conditions. Longueuil said the park would close during active work and that the timing would not be announced in advance, partly to protect public safety and prevent interference.
An air-rifle operation in a closed urban park differs from public hunting. It requires an approved safety plan, clear exclusion zones, qualified shooters and a method intended to produce a rapid death. Authorization does not remove the need for independent oversight and transparent reporting afterward.
What happened next
The cull began on October 22. By December 12, Longueuil said the operation had been completed and 105 deer had been killed in two phases. The city reported that usable meat was distributed through community organizations rather than discarded.
The final number was a later outcome, not information known when the permit was first announced. Adding it clarifies the record without erasing the earlier uncertainty or the objections raised by residents and animal-welfare groups.
Population control is not a one-time solution
Reducing the herd can relieve immediate browsing pressure, but an urban park remains attractive to deer if food, cover and surrounding movement routes do not change. Monitoring vegetation and annual deer numbers is necessary to determine whether the ecological target is actually being met.
Municipalities can also discourage intentional feeding, improve road warnings and fencing where appropriate, and assess fertility-control research as methods evolve. Each approach has costs, limits and welfare implications; describing one as painless or permanent would be misleading.
How to judge the decision
The central questions are measurable: how many deer the habitat can support, what damage was documented, which alternatives were technically feasible, how human safety was protected and what happened to the ecosystem afterward. Ethical disagreement can remain even when those facts are clear.
Longueuil’s permit resolved the immediate legal authority to act, not the wider public debate. Responsible coverage should represent the city’s ecological rationale, the serious welfare objections and the confirmed outcome without depicting critics as anti-science or presenting the municipality’s preferred population level as beyond scrutiny.
