The Metro Vancouver Regional District (MVRD), Metro Vancouver Housing Corporation (MVHC), Greater Vancouver Sewerage and Drainage District (GVS&DD), and Greater Vancouver Water District (GVWD) are each governed by a separate Board of Directors composed of elected representatives appointed or elected from their respective member jurisdictions. The number of directors appointed to each of the Boards is determined by the population of the member jurisdiction. Under the Local Government Act, the Board Chair establishes Standing Committees and appoints members to these committees, including a member to preside as Chair. The purpose of the committees is to advise the Boards on policy and other matters.
