The Ontario government is asking hunters to submit samples from harvested white-tailed deer to the Chronic Wasting Disease (CWD) surveillance program. CWD is a fatal, untreatable brain disease affecting members of the deer family, including white-tailed deer, elk, moose and caribou. CWD has not been found in Ontario wildlife but has been detected in all five U.S. states bordering Ontario, as well as British Columbia, Alberta, Saskatchewan, Manitoba and Québec. Hunters submitting a deer head are asked to provide their contact information and the date and general location of harvest. To report roadkill deer in the surveillance area that may be suitable for testing, call the ministry’s Wildlife Health Information Line at 1-888-574-6656, or email CWD@ontario.ca.
