Yesterday Canon has announced two new wide angle lenses and both with image stabilization. Only in the last few years have we seen Canon offering Image Stabilization in wide angle lenses. I've always had my eye on the Canon 16-35mm F/2.8L which is an amazing lens that retails for $1700 dollars.
The new Canon 16-35mm F/4L introduced yesterday may not be as fast, but does offer image stabilization. Whether you think you need Image Stabilization on a wide lens is subjective, but it is $500 dollars less as still rated as an L series lens. [Found Here]

The new Canon 10-18mm IS STM Lens is designed for EF-S mounts (APS-C) cameras such as the Rebel series or new Canon 70D. This can also be used on BlackMagic Cinema Cameras with EF mounts and at under $300 dollars a great option versus the popular Tokina 11-16mm (which does not have IS). The STM (stepper motor) means is should work well for auto focusing, especially targeted for use in video mode where you need full time auto focus. [Found Here]
