It is a troublesome year for Trudeau’s administration before the 2019 federal election. On the one hand，both the domestic politics and foreign relations have been greatly impacted by all kinds of crisis. In addition，the vigorous criticism from the opposition party has also made the voters have more question about the ability and credibility of the Liberal government. On the other hand，the Liberal government actively adjusts its budget and policies，paying more attention to issues that voters value，and settles with the United States on the steel-aluminum tariff issue which is expected to promote the approval of the USMCA and also allow the Liberal Party to maintain certain advantages in election. Therefore，the competition for the federal election in October will be very tight. Trudeau still has a chance to win，but his advantages have gradually narrowed. Moreover，the minority governments have gradually gained ruling opportunities in several provinces，which means minority’s party will be another growing force in federal election. Therefor，even if Trudeau wins the election，the federal government will still face more constraints in the future.
