Some members of Trudeau's cabinet were expected to join the dinner, a senior Canadian government official told CNN. Trudeau is also expected to leave Mar-a-Lago shortly after the dinner.
How has Trump's victory affected the neighborhood near Mar-a-Lago?
The dinner comes just days after Trump promised massive increases in tariffs on goods from Mexico and Canada starting on the first day of his administration, specifically calling for a 25% tariff on all products shipped to the US.
Trump's punitive tariffs, if implemented, could wreak havoc on US supply chains and industries that rely on goods from the country's closest trading partners.
CNN previously reported that after the president-elect's announcement, Trump and Trudeau had a brief call focused on border security and trade. A Canadian government source described the call as productive and told CNN that both promised to stay in touch in the days ahead.
During Trump's first administration, the United States and Canada sometimes had a difficult relationship, particularly on trade. Trump used tariffs against Canada during negotiations to replace the North American Free Trade Agreement.
