CIP is made up of a number of regional affiliate planning associations:
APPI - Alberta Professional Planners Institute
APCPS - Association of Professional Community Planners of Saskatchewan
API - Atlantic Planners Institute
MPPI - Manitoba Professional Planners Institute
OPPI - Ontario Professional Planners Institute
OUQ - Ordre des urbanistes du Québec
PIBC - Planning Institute of British Columbia
My understanding is CIP sets minimum standards for membership but each affiliate has their own membership requirements and procedures, and then administers their own members. I’m not sure if you can get a CIP membership without going through one of the affiliates. If you can’t I’d suggest researching each affiliate to see who has the easiest/quickest membership process and sign up through them.
