Oak wilt is an exotic invasive disease that kills all species of oak, preferring those in the red oak group (red oak and black oak). The Canadian Food Inspection Agency (the lead agency in dealing with exotic invasives) is working hard to keep oak wilt out of Ontario, but it is currently only 500 m from the border (on Belle Island in the Detroit River). Infected red oak trees can die in as little as 30 days.

If you suspect that a tree might have oak wilt, contact the Canadian Food Inspection Agency at 1-800-442-2342.
