According to Pilon & Lagace (Les Odonates du Quebec), Hudsonian Emerald is not found in your province. Size can also be a good indicator between Lake & Ringed (Lake emeralds being larger), though it is sometimes difficult to judge this in the field. [edit] S. hudsonica is listed in the identification key as hypothetical. I could not find any online resource to confirm it's existance in Quebec.

3 species of emerald have rings on the abdomen, Lake, Ringed and Hudsonian. The first 2 are definitely in range, the third might be but I can't tell from the tiny map I have. If there are no yellow markings on the side of the thorax, it is Lake emerald, S. cingulata

Emerald perhaps?
