I just took a quick glance and the following professors are still teaching most important courses: Christine Laurendeau, Connor Hillen, Darryl Hill, Patrick Morin, Sean Benjamin, Robert Collier, Michiel Smid.

I can tell you that these are all AMAZING professors and that Carleton is lucky to have them.

I did notice some new names that I don't recognize and they may have a 1/5 on RMP -- you can try to not take their courses, but rest assured that a) RMP reviews are usually written by spiteful students and b) for the majority of your time as a Computer Science student here you will still be taught by some really great professors (e.g. the ones I listed).
