Why is Shaw running tracking scripts?

If I type an invalid URL in my browser, I am automatically redirected to assist.shaw.ca, which runs the edgesuite.net script. It apparently is: "network of sites, cookies & other technologies used to track you, what you do and what you click on, as you go from site to site, surfing the web". If Shaw is going to automatically redirect me, it should at least have the courtesy to not run any tracking scripts.
