Governor General Mary Simon Welcomes Four New Diplomats to Canada in Rideau Hall Ceremony

Diplomatic Credentials Presented at Rideau Hall

Her Excellency the Right Honourable Mary Simon, Governor General of Canada, officially received the credentials of four new heads of mission during a ceremony held at Rideau Hall in Ottawa on December 3, 2025. The presentation of these letters of credence marks the formal commencement of the diplomats' missions in Canada, signifying their official recognition and authority to represent their respective nations.

The ceremony, which took place at 2:30 p.m. in the Rideau Hall Ballroom, is a cornerstone of diplomatic protocol. Upon their arrival in Canada, new ambassadors and high commissioners must present these official documents to the Governor General before they can fully undertake their duties. This tradition establishes formal diplomatic relations and sets the stage for future bilateral cooperation.

New Heads of Mission Officially Recognized

The four distinguished diplomats who presented their credentials to Governor General Simon are:

• His Excellency José Luis Guterres, Ambassador of the Democratic Republic of Timor-Leste
• Her Excellency Auđbjörg Halldórsdóttir, Ambassador of Iceland
• His Excellency Jovan Mirković, Ambassador of Montenegro
• His Excellency Martial Ndoubou, Ambassador of the Central African Republic

The letters of credence are crucial documents that formally accredit a diplomat as an ambassador or high commissioner for another country. Their acceptance by the Governor General signifies Canada's official recognition of their diplomatic status and their authority to engage in discussions on behalf of their home nations.

Strengthening International Ties

During the ceremony, Governor General Simon emphasized the importance of global collaboration. She stated, 'We are all connected. The well-being of one nation shapes the well-being of others.' She also encouraged the new heads of mission to embrace a spirit of cooperation and to connect with communities across Canada, highlighting the country's remarkable diversity.

The Governor General's role in such ceremonies underscores Canada's commitment to fostering strong international relationships. By officially welcoming new diplomats, Canada reinforces its ties with other nations and promotes dialogue on global issues. The event also acknowledged that the ceremony took place on the unceded territory of the Algonquin Anishinaabe Nation.
