Yes, I saw a similar email this morning. Didn't click on any of the links since I already created a tracker account on Jan 14. I logged in to the tracker expecting to see some kind of update but nothing had changed.
https://cst-ssc.apps.cic.gc.ca/ is the old link which no longer works. As you already have an account on the new tracker continue using that. Looks like IRCC forgot to update there email template with the new URL.
Thanks @toughchick and @forw.jane . Sounds like just need to overlook that email.
