You need both Pickleball BC (PBC) and Pickleball Canada (PCO) memberships because they function as a mandatory, bundled package to ensure you are insured, and that your club supports both provincial and national development. PCO covers national insurance and programs, while PBC manages provincial advocacy and safety standards (100% membership required for affiliated clubs). This bundle is explained on the registration page that you went to.

Dual membership provides you and your family with:

• Insurance Coverage: PCO provides a common policy for liability and accident insurance, but this coverage is contingent upon being a member of both the provincial (PBC) and national (PCO) organizations.
• Club Affiliation Requirements: Most pickleball clubs in B.C. are affiliated with PBC and require 100% of their members to hold both PCO and PBC memberships to maintain their own insurance and status. V-Club is an alternative if you do not belong to a club.
• Fundraising and Development: The combined membership structure (often done through the PCNS system) ensures that provincial, specific to B.C., and national organizations have the funding to run tournaments, coaching programs, and officiant training.
• Simplified Registration: You cannot join one without the other, as the Pickleball BC site states you should not submit separate forms; a club membership handles both at once.
