I've been trying to identify this caterpillar. The closest I can get is Tomato Hornworm, or Tobacco Hornworm, but neither of those are quite like this one.
It is about 4 inches long, and as big around as an adult's little finger. I found him on the ground, so can't say what plant it may frequent.
Also it was almost dark so I couldn't get the best pictures of it.
Located in Southwestern Ontario, Canada

Any help would be appreciated.
