If this continues, the WSHL will likely have more Canadien teams than American teams.
Technically that's already the case as the Vancouver Devils make 5 Canadian teams. And not counting Valencia who is still listed on the website (and El Paso), Bellingham, Seattle, Dallas and Witchita are the other remaining teams. Although, Witchita's website link is dead so I'm assuming the team is as well, and while Dallas is still live, I can't see how they would survive being all alone, and with really no other option than to fold considering they share an arena with the existing NA3 Mid Cities Jr. Stars.
The league's best bet would be filling in some Pacific Northwest teams to shore up Bellingham, Seattle, and now Vancouver, and possibly seeing if they can find a couple other Canadian markets that have been passed over by other junior leagues up there.
Edit: Also after clicking on the Valencia website, it looks like they are setting up a youth program based out of a new rink in Santa Clarita, so maybe the WSHL has a commitment from them to rejoin the league in the future to complete that program top to bottom.
