No your carrier doesn't know or care you are rooted... unless you do break something and bring it in asking them to fix it, then they will tell you you broke it yourself tough luck. (unless of course you reverse everything back to stock first)
FIRST read all (really... read all of it) of the 2nd and 3rd thread in "AT&T Samsung Galaxy S 4 General"
[GUIDE][INFO] The beginner's info thread (aka. the noob helper) and [HOW-TO] The ULTIMATE All-In-One Guide - I337M & MDL - MF3 - MK2
Then you can root. The "CF Auto-root" method works perfectly on all the Canadian carrier versions (they only differ in carrier bloat.), then install a custom recovery, then install a good backup utility, I suggest TiBu (which will also allow you to remove Knox).
Yes, I know this is my first post, and you may think I don't know much about rooting, but I have had some experience in the past. I did root my Samsung Galaxy Tab 2, first time I soft bricked it, then actually got to root and stuff to work, so I have some knowledge on what I am doing.
Those two threads that you have linked me, I have looked over and learn't some stuff from them. I have also downloaded CF Auto-Root for the I337m version. I know how to work it, through using Odin and download mode, exact same way I rooted my tablet.
I just have one more question though, rooting it with odin through download mode, that bypasses KNOX and allows the root to work? Cause if I tried rooting with any program like motochopper, KNOX would block it.
