Despite Prime Minister Justin Trudeau's congratulations to Trump on his election and his promise to collaborate with him on trade and international security, the media has described the victory as a 'stunning upset'. A commentator from the Globe and Mail, a prominent daily in Toronto, noted that the election results have disrupted the traditionally stable Canada-US relations. The focus of Trump's campaign on strengthening borders in various aspects such as trade, immigration, and security has raised concerns for Canada, which relies heavily on cross-border dealings. The commentator pointed out that Canada is facing potential challenges due to Donald Trump's promise to undo many agreements that Canada has worked hard to establish. Despite Canada's efforts to mitigate the threat of protectionist US actions through free-trade agreements, Trump has vowed to dismantle NAFTA. Canada is the largest trading partner of the US, with over 75 percent of its goods and services being exported to the US. Canada shares approximately 4,000 miles of territorial boundary with America, excluding Alaska. A potential NAFTA termination would have negative consequences for the Canadian economy. During his campaign, Trump focused on the idea of stricter border control, which could lead to slower traffic and trade, something Canada cannot afford. Trump promised to bring back jobs to various states and criticized NAFTA as a "disaster" that he would consider renegotiating or breaking. However, many economists and analysts believe that the protectionist rhetoric in the US election may not necessarily translate to the same policies once in office. In addition to criticizing NAFTA, Trump has also raised concerns about NATO and suggested that allies should contribute more towards US protection. Canadian officials are reportedly preparing for potential challenges ahead as the shockwaves of the election outcome continue to be felt. Experts anticipate that there will be significant changes in various areas such as economics, trade, environment, security, defense, and international relations under the new US administration. Prime Minister Trudeau is continuing to push for climate-change policies aimed at reducing greenhouse-gas emissions, but the presence of President Trump in power may make it more difficult for him to gain support for these policies in Canada. Trudeau refrained from criticizing Trump during the election campaign, likely in an effort to prioritize Canada's interests and foster a strong relationship between the two countries. Despite challenges posed by Trump's "America First" stance, there are still areas of cooperation such as cross-border security arrangements and NORAD, a military air defence alliance. However, it remains to be seen how successful Trudeau will be in advancing the Canadian agenda under a protectionist US president like Trump, leading to questions about whether Trump poses a new dilemma for the Canadian PM. It will require some time before we receive the answer.
