Canada is recognized as a middle power for its role in international affairs with a tendency to pursue multilateral solutions. Canada's foreign policy based on international peacekeeping and security is carried out through coalitions and international organizations, and through the work of numerous federal institutions. Canada's peacekeeping role during the 20th century has played a major role in its global image. The strategy of the Canadian government's foreign aid policy reflects an emphasis to meet the Millennium Development Goals, while also providing assistance in response to foreign humanitarian crises.
