India-Canada Relations Strained Over Sikh Separatist's Killing

India has asked Canada to reduce its diplomatic staff by over half as tensions escalate following Canadian Prime Minister Justin Trudeau's public allegations that Indian agents were involved in the killing of a Sikh separatist leader in Canada. The fraying relations have led to a series of diplomatic and trade actions, including the suspension of trade treaty talks, the postponement of a trade mission, the expulsion of diplomats, and the slowing down of a stake purchase by an Indian company. The two countries have also exchanged tit-for-tat visa suspensions and urged their citizens to exercise caution.
