Are you looking at the MM in OR program or the Ph.D. program? The MM in OR program is more of a professional degree while the Ph.D. is research oriented. In terms of quality, the number of faculty speaks for itself (obviously far from GaTech or MIT) but I think it's still a decent size. My experience with UBC is that it has a very good reputation with employers, and the pacific northwest offers quite a few employment opportunities. I can't really speak for the OR department specifically as I'm a student in the CS department working for a professor in OR, but based on what I've seen, I feel that if you can't get into one of the top OR programs (e.g., MIT, GaTech, Stanford), it's not a bad alternative.
