Nice sunglasses and are legit.  I did register them on the Oakley site with no problems except they registered with the Canadian Oakley website but I don't think that will be a problem.  They came with all the correct paperwork and box with the registration card.  The best way to tell if they are real or not is if there is any optical distortion when looking up or down through the lens.  Any fake Oakley that I've ever seen has distortion and these have none.
