Through fares have pretty much dried up and pricing is approximately the summation of the segment fares. Everything through SEA to/from Canada was significantly cheaper than Canada to/from SEA. Recently, for a close in LAX-SEA-YVR, AS was asking $1042 in Main. Domestically there were a lot too. PHX-SEA-ORD was quite often $100. I did, however, book SJO-LAX-SEA-YVR in February for $368, definitely cheaper than the segments.
