As of right now at PCL, if you have low time, you're gonna be in the right seat for a while. You need 3000TT to upgrade in the CRJ here. They've been talking about reducing the mins, but I haven't seen any hard evidence that they will. Quite the opposite in fact, since in the last check airman class both the FAA and one of the standards guys for the airline said "no" to the reduced mins question. I got hired right around 1000TT, and even I'll have the seniority to bid CA before I have the hours.
That being said, it could change at a moments notice. Look at XJT for an example. Their mins are ATP mins, but used to most of the guys that upgraded would be around the 2-2 1/2 year mark before upgrading. Recently, I've heard guys are gonna be upgrading right at mins over there. Then you could see the reverse happen, a la Colgan in the Saab. I think a lot of the guys over there are saying upgrade times have slowed down quite a bit.
