You didn't try very hard, I had no problem finding it from the link supplied by dmroeder.
Read the instructions on the Canon site.
1. Select OS
2. Select the file, scroll down (Read what's on the page) agree to terms & conditions.
If you can't follow instructions on the download site, we can't help beyond that point.
