Mystery Animal...what do you think it is?

[Catherine]

There is a mystery animal near the lake shore on the east side of Toronto. Someone got a good picture, but no one is sure what they are seeing.  I will definitely say it is not a skunk.

This is a Fisher



This is a mink



This is a Martin


This is a skunk



This is the mystery animal.



This is another Fisher picture.



It is probably a Mink. I have seen mink in Toronto. I have seen one that was dark like the animal in the picture. It is clearly not a skunk or raccoon. I doesn't look like a Martin.
It would be amazing if it was a Fisher. That would mean they are returning to the area. 
It looks like a Fisher. What do you think?
