Are Snakes in Ontario Dangerous?

“Snakes…why’d it have to be snakes?” – Indiana Jones

From the Bible to Raiders of the Lost Ark, snakes have gotten a bad rap throughout history due to their deadly bite and slithery ickiness. However, as with most animals, they’re generally more afraid of humans than the other way around, and will not attack unless they feel threatened.

“But what about poisonous snakes in Ontario?” you might ask. Thanks to our cool climate, there is only one native poisonous snake species in Ontario, the Eastern Massassauga Rattlesnake.

The Eastern Massassauga Rattlesnake grows to a metre in length and has bluish-gray scales, which makes it easy to step on during a hike if you don’t hear its trademark rattle. While the Eastern Massasauga Rattlesnake bite is poisonous, only two Ontarians have died from it, the last one occurring in the ‘60s.

While a small number of cottagers receive Eastern Massasauga Rattlesnake bites every year, the poison is slow acting and can be treated with a timely visit to the hospital. The only real danger is you don’t seek proper medical attention after getting bitten.

However, that hasn’t stopped the destruction of snake habitats in Ontario, leading the Eastern Massasauga Rattlesnake to face Threatened status in the Georgian Bay area and full-blown endangered status in the Windsor area.

Besides the Eastern Massassauga Rattlesnake, there are no other native species of poisonous snakes in Ontario.
