The Canon DSLRs already have an LCD protector. That exterior sheet of plastic is not the surface of the LCD. That's just a plastic cover stuck on the back of the camera by adhesive strips.


You can buy another cover from Canon for about $15 (it comes with more adhesive stripping). Use a big kitchen suction cup to remove the old cover and stick on the new one.


So you don't really need a protector--it's already got one. Unless you want a protector for the protector.
