Was about to renew my Cypress pass and double checked this.
As far as I can tell, Cypress is owned by Boyne Resorts (Michigan based.)
Seymour seems owned by a local Vancouver family while Grouse is owned by Northland Properties Corporation which started in BC and is headquartered in Vancouver.
Looks like I’ll be trying out Seymour next season!
I have no idea how Boyne affords that. Boyne “Mountain” sucks.
