I'll take a wild guess here and say "Image Stabilization".

Image Stabilization (IS) - An optical system for removing or reducing camera movement in zoom lenses. Using gyroscopes an internal lens is moved around to counteract the movement of the camera. This usually allows you to shoot at 2 to 3 stops slower than a camera without IS under the same conditions.

The sigma may or may not be compatible with your camera, whereas a Canon is compatible with Canons. For example, a Nikon lens will not mount onto a Canon mount. Otherwise, there appears to be no difference. The Canon probably has better glass in it than the Sigma.
