The Organization of Petroleum Exporting Countries (OPEC) is an intergovernmental organization of oil-producing nations that coordinates petroleum policies and production levels to influence global oil prices. While Canada is not an OPEC member, OPEC decisions significantly affect Canadian energy economics because global oil prices impact Alberta, Saskatchewan, and Newfoundland and Labrador's petroleum industries. When OPEC increases or decreases production, resulting price changes affect Canadian government revenues, energy industry employment, and the prosperity of oil-dependent communities. Municipal governments in energy-producing regions experience economic cycles influenced partly by OPEC decisions affecting global petroleum markets.
