I have seen Sharpies along the open foreshore at Boundary Bay. Ilya said he has also seen a Sharpie with you at the foot of 64th
I agree Sharpies and Cooper's are pretty much variable in every feature. However, normally I find breast streaking patterns in juveniles as a fairly reliable tool; especially when you have other supportive features in the bird. In this bird the breast streaking looks as I've described in the previous posts above. I feel it fits much better for Sharpie as opposed to a Coop. The placement of the eye seems fine for Sharpie to me. I also feel that the eye placement can appear varied due to the posture of the head. The bird seems to have a no neck appearance to me. Leg thickness can be very hard to judge sometimes, especially if it is a larger female Sharpie. Here is a webpage that shows thicker legged juvenile Sharpies and the difference in eye colour:

Also, in regards to the eye it looks orange to me which is a sign of a juvenile Sharpie while a juvie Cooper's would have a bright yellow eye. You can even see the contrast in the yellow on the bill in comparison to the orange eye in Neal's shot.
PS. I have got a second opinion as requested from Peter Candido, Chris Charlesworth and Yousif Attia, who also agree with SSHA.
