Although the 12-24mm f/4 Tokina ATX wide angle lens is built to be used on a 1.6x format body, It is not an EF-s lens.
I am glad about that because I have just obtained an older Canon D60 camera which has been modified for full-time infrared photography. I can use my 12-24mm Tokina on this camera but, could not have used the 10-22mm Canon on my "new" D60!
