The endangered Massasauga rattlesnake is the only venomous snake in eastern Canada and a small population slithers around the Georgian Bay Islands National Park. Tan-coloured with dark brown blotches, an adult specimen is 50 to 70cm long with a heavy body and triangular head. In the unlikely event you stumble across one, give it a wide berth. The snake prefers marsh and mixed forest, so if you are hiking in this kind of habitat, be sure to pick up one of the advisory leaflets at a visitor kiosk.
