As memtioned, Canon EF or EF-S lens will work with your camera. I have an EF 50mm f/1.8 lens dated back in the late 80s and still works great with my EOS digital cameras.
There are some 3rd parties lenses such as the one from Tamron, Sigma and Tokina that will also work with your camera. However, not all of them will work even it will mount on your camera body. Some of them need to be re-chipped in order to work. So watch out for that.
