In each of the fifty-one electoral districts, registered parties may establish Electoral District Associations (EDA). Each EDA must be registered with ENS, including an annual renewal. An EDA is endorsed by the leader of the registered party to further the goals of the registered party.
Several resources are available for the Official Agent of an EDA to use, including a Handbook and several Forms. (links)
Annual reporting is required. The forms for this reporting are 4-1 through 4-4.
Renewal of EDA: March 31
Change in information: 10 days after effective date of change
Annual Report: March 31
Fundraising : 120 days after event or March 31 (these are normally processed through the Party, since tax receipts are allowed to be issued only by the party or the candidate)
