Poison Ivy
I wasn't sure where to submit this but chose Ottawa because I took the picture on the Bikepath. Hope it's useful for those who can't identify. Glossy green leaves in threes sometimes with reddish hue, and sometimes notched. Possible skin contact should be carefully washed with strong soap. Do not dry hands with common towels. Severe reactions require medical attention. Serious lung problems can occur if ivy is accidently burned in campfires and fumes inhaled.
