August 10th - Hogweed!
It can cause third degree burns and permanent blindness, and its spreading!
Giant Hogweed is being found all over Ontario, it's possible people are moving it from garden to garden. Simply touching it won't hurt you, but its the sap you need to watch out for, and you won't even feel the effects right away but a day or two later. So make sure you Google what it looks like and keep away from it!
