Yes, any lens that can be used on a Canon EOS film camera...can also be used on a Canon EOS digital camera.
There is one thing to keep in mind. With most of the Canon Digital SLR cameras...then lens will give you a different field of view that you are used to on the film camera. This is because the digital sensor is smaller than 35mm film...so sensor only 'sees' the middle of the image projected by the lens.
