Canada’s long history of expelling diplomats
OTTAWA — Canada’s expulsion of a Chinese diplomat following allegations of a threat campaign against a Conservative MP marks the first time in five years a foreign representative is told to pack up and leave the country.
It’s rare but not unheard of for Canada to expel diplomats.
Declaring someone persona non grata — an unwelcome person — is dictated by a 1961 United Nations treaty called the Vienna Convention on Diplomatic Relations.
It says a receiving state can at any time, without any explanation, declare a member of a diplomatic mission persona non grata and prompt them to leave the country.
