Canadian Prime Minister Mark Carney, in the context of US President Donald Trump's threat to seize Greenland, recalled NATO's Article 5, which implies collective defense in the event of an attack on one of the members of the North Atlantic Alliance. RIA Novosti writes about this.

“We are NATO partners with Denmark and our full partnership continues. Our obligations under Articles 5 and 2 of the North Atlantic Treaty remain in force and we fully support them,” Carney said.
Article five of the NATO treaty stipulates that an armed attack on one of the members of the alliance is considered an attack on all members of the alliance and requires a collective response, including the provision of necessary assistance, including the use of armed force at the discretion of the member states.
Trump dismissed the question of being willing to take over Greenland by force
On January 16, Politico wrote that if the US attacks Greenland, Denmark will have other “rescue” options besides NATO support. Specifically, Copenhagen can invoke Article 42.7 of the EU Treaty for mutual protection.
Journalists note that NATO is the foundation of Denmark's security, but the alliance is “unable to provide significant support in the event of a confrontation with the United States,” because “America dominates NATO.” Therefore, Denmark can invoke Article 42.7 of the EU Treaty, which is even more “attractive” than Article 5 of NATO, because the content of the European article clearly states the obligation of Alliance countries to help victims of aggression. Article 5 of NATO includes the wording “when necessary,” Politico writes.
Trump has previously threatened tariffs on countries that oppose the US annexation of Greenland.
