Pros
You get to work in a relatively warm environment with new technologies in the sawmilling realm. The first jobs you get are menial, dirty and back breaking, usually on a night shift which are hell on your body and mind, eventually you can begin to tolerate it. The light at the end of the tunnel is bidding off cleanup and getting on the line where you can make good coin. Normal operations you get 1 hr OT a day or 10 per check which adds up real fast. Boring but rewarding work when you break a production record. Also most of the managers are pretty good guys and are flexible.
Cons
Personally the shift work is the best and worst thing about working at Canfor. Some guys love working the afternoon shift so they can run around in the morning and get stuff done around town, banking, shopping, minding the kids while the wife is at work. Most however just tolerate it and look at the paycheck. The changing from nightshift to dayshift every 2 weeks takes a toll on your body and sleep is sometimes at a premium, especially in the summer when you're trying to sleep through the hottest part of the day. Also missing evenings for me when I want to go out with my buddies or play in my sports leagues.
