can someone ID a animal track for me? pics included. SW Ontario (1 Viewer)

I know it's not bird-related but I don't know where else to ask.

I have 4 pics of these paw prints that I snapped the other day on my hike in the Dundas Valley. would love to know what they are. they aren't raccoon, not a dog.. so let me know if you want to have a look and can help and I'll post em up

sorry if this is the wrong forum for this

thx!

Hi Bruce,if you click on forum's tab,scroll down to "nature in general","mammals & sealife" be a great place.
Have had thoughts of porcupine's "stickin" in mind all day...

Heres a link to site up your way of various critter tracks,might save some time.

thanks Bird Bill - I'll try there =)

oh and I don't think it's a porcupine. think we're too far south for those
