Province launches annual surveillance program to help detect chronic wasting disease
As Ontario's hunting season begins, the provincial government is calling on hunters and farmers to help protect wildlife by participating in its annual Chronic Wasting Disease (CWD) surveillance program.
The program is designed to detect the disease early and provide wildlife officials with important information about the health of Ontario's deer population. Early detection remains one of the most effective tools for preventing the spread of wildlife diseases and supporting rapid response efforts.
This year's surveillance program will focus on selected areas in Southern and Eastern Ontario. Hunters who harvest white-tailed deer that are at least one year old in these regions are encouraged to submit samples for testing.
Chronic Wasting Disease is a fatal neurological disease that affects members of the deer family, including white-tailed deer, moose, elk, and caribou. Although the disease has not been found in Ontario wildlife, it has been detected in neighboring provinces and several bordering U.S. states, making ongoing monitoring an important priority.
The province offers several convenient ways for hunters to participate. Deer heads can be dropped off at designated freezer depots operating throughout the hunting season. Wildlife technicians will also be conducting field sampling in targeted surveillance zones, collecting small tissue samples from harvested deer with hunters' permission.
In addition, participating butchers and taxidermists located within surveillance areas will assist with sample collection. Officials note that sampling does not prevent hunters from consuming venison and generally does not interfere with taxidermy services.
To encourage participation, the first 500 hunters who submit samples in each surveillance area will receive a commemorative crest and a sample identification card. The card allows hunters to access test results online approximately six to eight weeks after submission.
Wildlife experts stress that CWD does not pose a known risk to human health, and there have been no reported human cases linked to the disease. However, monitoring remains essential to help prevent disease from becoming established in wildlife populations.
Ontario is also asking residents and hunters to report animals displaying signs of illness, including unexplained weight loss, tremors, lack of coordination, drooping posture or unusual behaviour. Reports help wildlife authorities investigate potential health concerns and strengthen surveillance efforts.
The annual program is part of Ontario's broader strategy to safeguard wildlife health, preserve hunting opportunities, and maintain healthy deer populations for future generations.
By submitting samples and reporting sick animals, hunters continue to play a valuable role in supporting science-based wildlife management across the province.
