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!
Cyprus used to me a park. It’s been a while since I was there
