Canadian Prime Minister Justin Trudeau said that the federal government was aware of the intended arrest but had no involvement in the process due to the judicial independence of the Public Prosecution Service of Canada. According to David MacNaughton, Canada's former ambassador to Washington, the extradition request was made very suddenly on 30 November, with no discussion between U.S. and Canadian officials. However, MacNaughton also says the U.S. has several agendas in going after Huawei, one of which is that it wants its allies to ban it. A close adviser of Justin Trudeau says the view inside the Canadian government is that John Bolton was the driving force behind the arrest of Meng. Trudeau was informed of Meng's arrest at the G20 summit in Buenos Aires, and according to one source, was caught off guard.
