During Justin Trudeau’s second year in office，Canada made full play of its strengths as a traditional middle power in foreign policies to manage its relationship with the United States，engage in international diplomacy and build bilateral ties with countries and regions around the world. However，like many other middle powers，it also suffered from certain embarrassing dilemmas in its foreign relations. Internationalization and multilateralism remains the main theme of Justin Trudeau’s foreign policy，and Canadian participation in issues of international concern was increased. On one hand，such participation helped to enhance Canada’s international image and discourse power，and thus improving its chance of reclaiming its status as a member of the Security Council. On the other hand，Canada’s policies were still heavily influenced by the United States，especially when it comes to issues regarding China. Canada experienced difficulties in its free trade negotiations with its two most important trading partners. As the Prime Minister’s diplomatic visits failed to produce results，the Canadian public began to feel less satisfied with their country’s international image. Meanwhile，due to various factors，China-Canada relations came off early highs. The lack of a consistent policy towards China proved to be one of the disadvantages of Canada’s current foreign policy，and the future development of China-Canada relationship calls for more concrete cooperation between the two countries.
