Prime Minister Narendra Modi has conveyed concern about "continuing anti-India activities of extremist elements in Canada" in a bilateral with Canadian Prime Minister Justin Trudeau held on the sidelines of G20. Canada has been one of the favoured hubs of expat Sikhs, where extremism has mushroomed along the margins and made headlines over the last few months. PM Modi conveyed to Mr Trudeau that the extremist elements in Canada are "promoting secessionism and inciting violence against Indian diplomats, damaging diplomatic premises and threatening the Indian community and their places of worship," the foreign ministry said in a statement.
