Not all dealers carry F-sport, I think some shy away from aftermarket parts in general because of warranty concerns. You can always order F-sport through Carson Toyota. If they do not want to ship them to Canada, then let me know and I can help you out.
Concerning the F-sport as a replacement for the F, it looks like the front is 355mm, which would fall short of the 360mm front brakes on the F.
