Moved
Moved from Coras. Happened upon this one and noticed it was misplaced. There's also Amaurobius borealis in Ontario, but it looks different enough to conclude this is most likely A. ferox (adult male).

Male
I do not know, but I can say it is a male. The "clubbed" pedipalps are how one can tell.

Not harmful.
Whatever this is, it is not dangerous to humans. Spiders that ARE dangerous, in North America, include only the widows (Latrodectus spp.), the brown spiders (Loxosceles spp.), and maybe the "hobo spider" (Tegeneria agrestis). Naturally, anyone with sensitivity to insect stings and other arthropod venoms should probably avoid close contact with any spider. This specimen might be a male hackled-mesh weaver, family Amaurobiidae.
