I'm not so sure about imm Red-Shouldered. This bird appears to be a buteo, and a chunky one. Red shoulders are more slender / less bulky looking. Also the number and width of the tail bars is not matching up with the photos I have viewed online of red-shouldered. Additionally, the cere should be yellowish in a red-shouldered and this photo has an all dark bill and cere.
But I am confused as to what this bird is also.

We thought more like Red-tail Hawk size. Did not see it fly.   Thanks.

It's hard to tell size from the photo. Do you think it was Sharp-shinned hawk size or more like Red-tail Hawk size? Did you happen to see it fly? A description of its underside and front would be helpful.

Hello,
My wife and I went for a ride around Fir Island and got a picture of this Hawk.  https://flic.kr/p/2n82Wbg
We were not able to decide what it was. Please help.
Thanks.
