In the year of 2018，the economic growth of Canada was moderately slow. The economic fundamentals were healthy. The overall economic environment remained at the forefront of the world. The inflation rose slightly，employment maintained a good momentum，and the total trade deficit continued to shrink. Under such circumstances，the Canadian government took proactive measures to deal with the uncertainty of global economy in order to tap the potential of national economic development. In terms of domestic political and social governance，Trudeau government’s ruling pressure had been mounted and the new round of federal election is fiercely competitive. The domestic security situation continued to deteriorate yet the terrorism posed relatively less threat to national security. Investing in the middle class remained the priority of national policy and new supportive measures continued to be introduced. In regard of diplomacy and international profile，Canada’s great power diplomacy had encountered twists and turns. Its trade diversification strategy had been frustrated. And Canada was criticized for falling short of its action in foreign aid. And the human right diplomacy was accused for being double-standard. Its national reputation and overall global image declined. Besides，its softer power strength had been on the decline for two years.
