If you see a snake in High Park, consider yourself lucky. Typically, snakes are secretive, hiding between in cool spaces between rocks or hunting in long grass. High Park is home to two species of snake: the common Eastern Garter Snake and the uncommon DeKay's Brownsnake. No snakes in High Park or Toronto are venomous.
Garter Snakes
The Eastern Garter Snake (Thamnophis sirtalis sirtalis) is widespread throughout North America and common in High Park. These snakes are far-ranging due to an unparticular diet and their adaptability to different habitats and landforms, with varying proximity to water.

Garter snakes, like all snakes, are carnivorous. Their diet consists of almost any creature that they are capable of overpowering: slugs, earthworms, leeches, lizards, amphibians, birds, fish, toads and rodents. When living near the water, they will eat other aquatic animals. Food is swallowed whole. Garter snakes often adapt to eat whatever they can find, and whenever, because food can be scarce or abundant. Although they dine mostly upon live animals, they will sometimes eat eggs.

Eastern Hog-nosed Snake - Extirpated Species

The eastern hog-nosed snake has a thick body and neck that it flattens out like a hood, cobra style, when it’s disturbed. If it feels threatened, it will raise its head, flatten its neck to form a hood, hiss loudly and lunge with its mouth closed in the direction of the threat. If the bluff does not discourage the predator, the eastern hog-nosed snake goes to plan B. It rolls over and plays dead, hanging its tongue out of its gaping mouth. Then, to seem less appetizing to fresh flesh eating predators, this snake also vomits and empties its bowels to smell as rotten and foul as possible. If the snake is turned right again onto its belly, it will just flip back over and return to its playing dead routine.As it swallows its small prey, the eastern hog-nosed snake immobilizes its meal by injecting very mild venom through a set of fangs at the back of its mouth. It can’t inject venom into larger animals or humans and so is not harmful to humans. However, people who mistake it for a dangerous species often kill this snake.The eastern hog-nosed snake has not been reported in High Park for decades. This species is listed as a threatened species in Ontario and in Canada.
We brake for snakes
Sometimes when the air is cool and the sun is high, snakes come out to bask on rocks, paved paths or roads. Be sure to keep an eye out for snakes when cycling or driving through natural areas.
