I don't think this is a KVS issue.

It seems the problem isn't with the YOW - YYZ segment, it is with the YYZ - LAS portion. Since IKK is linked to R availability, you'll notice that R=0 for the 2nd leg, and this is why it won't give you the seat for 40,000. There are significant threads on this very topic lately.

Not sure why the cancelled flight is showing up on KVS or actually still showing up on aircanada.com for that matter.
