Trail cameras were used to determine the presence of medium to large-sized wild mammals in Ontario between 2008 and 2010. A total of 27 different species of mammals across the province were photographed during 17308 trail-camera-nights. Presence indices (photographs per trail-camera-night) for the areas sampled in southern Ontario were highest for the following species: White-tailed Deer (Odocoileus virginianus), Raccoon (Procyon lotor), Coyote (Canis latrans), Eastern Gray Squirrel (Sciurus carolinensis), and Red Squirrel (Tamiasciurus hudsonicus). Presence indices for the areas sampled in northern Ontario were highest for White-tailed Deer, American Black Bear (Ursus americanus), Moose (Alces alces), Snowshoe Hare (Lepus americanus), and Red Squirrel. Trail camera photographs depicted extensive use of snowmobile trails by wildlife in southern Ontario.
