Common Garter Snake (Thamnophis sirtalis)

The most frequently seen snake around Montreal. About half to a meter long and not poisonous.

How To Identify

Greenish with yellow stripes. As there are not many different snakes in Canada, not difficult to identify.

Where and When to Spot

I saw this species twice on my explorative walks through the parks in Montreal and both times in Park Angrignon, spring, in the forest area.
