Council is the governing body of The Corporation of Delta and the custodian of its powers, duties, and functions, both legislative and administrative. The Community Charter specifies that the purpose of local government (which is defined as being Council) includes:
- Providing good government for its community
- Providing works, services, facilities, and other things that the municipality considers necessary or desirable for all or part of its community
- Providing stewardship of the public assets of its community
- Fostering the current and future economic, social and environmental well being of its community.
In their role as Council, they collectively develop policies through the adoption of bylaws and passing of resolutions.
It is important to note that individual members of Council cannot make a decision on behalf of Council nor, individually, are they able to give direction to staff. To do either, they must give a collective direction as a group at a properly convened meeting.
Council may not grant special privileges or immunities to individuals or corporations unless the Community Charter specifically allows them to do so. Generally speaking, they cannot lend money to corporations, give away land, guarantee loans for business purposes, or give tax reductions.
The Community Charter requires that Council exercise its powers at regular or special meetings when a quorum is present. The Charter allows each municipality to establish the size of its Council by bylaw. The Charter also stipulates that if a bylaw is not adopted, municipalities having a population greater than 50,000 are to have a Mayor and eight Councillors. Delta has a bylaw that stipulates that Council consists of the Mayor and six Councillors. A quorum consists of four members.
