You are confused. Khalsa are PCSL league champions. UBC are Challenge Cup champions.
That said, I do agree that PCSL should not have a spot in provincials.
I know for sure I am not the only one confused here. I always thought that Challenge Cup was a play-off for the league (4 best teams) and that the winner of that Cup would actually represent PCSL in provincials (although, again, PCSL should not get a spot at Provincials and Khalsa is a perfect example having players from various VMSL teams; which team those players are going to play for in Provincials?)
