An envelope with an expletive-filled letter and a suspicious white powder addressed to the Craft was intercepted by an off-site mailroom supervisor on Thursday morning, Canadian media have reported.
Believed to have been mailed from Quebec, the letter threatened to kill the ambassador if she did not resign, and contained threatening comments against Donald Trump. The mysterious powder has been deemed harmless. Authorities are now investigating the incident.
Canadians flocked to Twitter to voice their disapproval of the incident, writing that no matter what differences may exist between their countries' leaders, such anonymous death threats are completely unacceptable.
Others, still angry over President' Trump's comments about the Canadian prime minister at last week's G7 summit, nevertheless condemned the incident as well.
Some users also took on a more conspiratorial tone, saying that they just couldn't buy the idea that a Canadian could have done this.
