Insect ID. Montreal, Qc (Canada)
This is a "click beetle" (Coleoptera, Elateridae). They have this name because of the loud click sound they produce. They are related to fireflies (Lampyridae), and some click beetle species are themselves luminescent.

According to the link above:


  A spine on the prosternum can be snapped into a corresponding notch on the mesosternum, producing a violent "click" that can bounce the beetle into the air.


I don't know about those North American beetles, but in South America I've seen click beetles jumping more than 30cm in the air.

Here is a photo of a click beetle in Montreal, from the Pest Control Canada website, which looks like your specimen:



Unfortunately, the entomologist that identified the animal in the photo above didn't narrow it down to Genus or Species.
