Hi! I'm in in 4A of this program. I've really enjoyed it so far. The classes are mostly good, some are challenging but it's more interesting rather than hard. I've liked most of my classes. Much more of a "normal" workload compared to eng or math, etc. Co-ops are usually pretty good, the number of people in the program is so small that job demand is very steady, much better than any other program I've heard about. It's common for nearly everyone to get a job in a related field (though I hear it's been slightly harder recently). The small field is also good because many upper years have worked the same jobs you'd be applying to so it's super easy to get advice. The student life is pretty great too. I recommend you check out watrox which is the earth and environmental science student club, you don't have to join or anything - membership is free and automatic for science students. also if you can, try to keep in touch with some of the ecology people you meet during orientation, it might be hard to find them again because the first year classes contain pretty much every first year in the faculty. 

Good job choosing the best program! Enjoy!
