Cultural protectionism in Canada has, since the mid-20th century, taken the form of conscious, interventionist attempts on the part of various Canadian governments to promote Canadian cultural production. Sharing a large border, a common language (for the majority), and being exposed to massive diffusions of American media makes it difficult for Canada to preserve its own culture versus being assimilated to American culture. While Canada tries to maintain its cultural differences, it also must balance this with responsibility in trade arrangements such as the General Agreement on Tariffs and Trade (GATT) and the United States–Mexico–Canada Agreement (USMCA).
