Calgary uses cwr as well. Granted, they're not delivered in quarter mile lengths, but once the rails are welded together it doesn't matter what lengths they had previously been for maintenance purposes because the rails are now continuous. Besides, welded rails are easier to maintain anyway since they don't chip out and dent at the joints.
Here's one of srperry's shots of the NW line extension in 2008 showing the welded rail as it is being brought onto the ties.
