Keeping CWD out of Ontario

Chronic Wasting Disease


Fall hunting seasons serve as a reminder that our deer, moose and elk populations are worth fighting for. You expect OFAH to lead the charge to help keep Chronic Wasting Disease (CWD) out of Ontario, and we’ve answered the bell.

In 2019, we hosted a CWD conference with international experts, initiated the Canadians Concerned About CWD stakeholder collaborative, made CWD a federal election priority, and most recently we developed a new video to raise awareness. Check out and share the video, The Risk of CWD Explained at


If you hunt deer in WMUs 8, 9A, 9B, 10, 13, 64B or 65, get your deer tested by either dropping off the head at a freezer depot or by having your deer tested by an MNRF crew (crews active Nov 5 to 16 in eastern Ontario and from Nov 5 to 29 in northwestern Ontario). Visit for all the details.


CWD is one of the greatest threats to wildlife in North America. It is highly infectious and 100% fatal to members of the deer family including white-tailed deer, elk, moose and caribou, resulting in population declines. CWD has not been found in Ontario but is in several neighbouring jurisdictions.
