It could also be an immature bald eagle. I was with a biologist fishing up near Thunder Bay when I pointed out a golden eagle only to be told that it was an immature bald. They look very similar but the balds are more common. Of course that was NW ontario so it might be different down here. I did find this with a quick google which might help:
Wikipedia Bald Eagle Article
"The plumage of the immature is brown, speckled with white until the fifth (rarely fourth, very rarely third) year, when it reaches sexual maturity.[2][5] Immature Bald Eagles are distinguishable from the Golden Eagle in that the former has a more protruding head with a larger bill, straighter edged wings which are held flat (not slightly raised) and with a stiffer wing beat, and feathers which do not completely cover the legs.[7] Also, the immature Bald Eagle has more light feathers in the upper arm area, especially around the very top of the arm."
Hmm, looking at their pic I think your right but I'm no bird expert:
