Canada is implementing new border security measures costing $900 million USD, including enhanced surveillance and a joint strike force with the U.S. This is in response to President-elect Trump's threat of a 25% tariff on Canadian goods if the border isn't secured against illegal immigration and drug smuggling. The plan addresses concerns about fentanyl trafficking and undocumented immigrants. This announcement follows the resignation of Canada's finance minister, creating further challenges for the government. The new measures aim to balance border security with maintaining the free flow of goods and people.
