TORONTO — Canada said it has identified India’s top diplomat in the country as a person of interest in the assassination of a Sikh activist there and expelled him and five other diplomats Monday, in an escalating dispute over the June 2023 killing and allegations of other crimes. [time-brightcove not-tgx=”true”] Prime Minister Justin Trudeau said Canada was expelling the Indian high commissioner and the others—all persons of interest, as Canada’s foreign minister said police had uncovered evidence of a worsening campaign against Canadian citizens by agents of the Indian government. “We will never tolerate the involvement of a foreign government threatening and killing Canadian citizens on Canadian soil,” Trudeau said.
