International Civil Aviation Organization (ICAO) headquarters is located in the Quartier International of Montreal, Quebec, Canada. ICAO full form is International Civil Aviation Organization. It is funded and directed by 193 national governments to support their diplomacy and cooperation in air transport as signatory states to the Chicago Convention (1944). Air Navigation Commission (ANC) is the scientific body within ICAO. Approved by the commission, rules are sent to the council, the political body of ICAO, for discussion and coordination with the member states before final permission.


The requirements ICAO standards include never supersede the importance of national regulatory requirements. It is always the local, and federal regulations enforced in and by sovereign states, which must be legally adhered to by air operators using applicable airspace and airports.

History of ICAO

The International Commission for Air Navigation was the precursor to ICAO (ICAN). It convened its first convention in Berlin, Germany, in 1903, but the eight countries that attended were unable to reach an agreement. Twenty-seven countries attended the second congress, which was also held in Berlin in 1906. The first radio callsigns for aeroplanes were assigned during the third convention, which was held in London in 1912. ICAN was in operation until 1945.

The Chicago Convention on International Civil Aviation, usually known as the Chicago Convention, was signed on December 7, 1944, in Chicago, Illinois, by 52 countries. Its terms called for the creation of a Provisional International Civil Aviation Body, which would be replaced by a permanent organisation once twenty-six countries signed the agreement. PICAO was established as a result of this.

PICAO, which took over from ICAN on June 6, 1945, was established as a result. The treaty was accepted by the twenty-sixth country on March 5, 1947, and PICAO was disbanded on April 4, 1947, to be replaced by ICAO, which commenced operations the same day. In October 1947, the International Civil Aviation Organization (ICAO) became a United Nations entity, reporting to the UN’s Economic and Social Council (ECOSOC).

Montreal is home to the International Civil Aviation Organization (ICAO).

Qatar offered to serve as the Organization’s new permanent seat in April 2013. Qatar proposed to build a vast new headquarters for ICAO and cover all relocation costs, claiming that Montreal was “too far from Europe and Asia,” “had chilly winters,” was difficult to attend due to the Canadian government’s sluggish visa issuing, and that the taxes imposed on ICAO were “too high.”
