Prime Minister Justin Trudeau dropped a bombshell Monday in the House of Commons when he cited “credible” intelligence that agents of Indian Prime Minister Narendra Modi’s government may be linked to the killing of 45-year-old Hardeep Singh Nijjar. Both nations, which have traded billions of dollars worth of goods over the years, have expelled each other’s diplomats and India has stopped issuing visas in Canada. A former foreign policy adviser to Trudeau says this may be the beginning of a months-long diplomatic spat with India. Exports to India last year amounted to $5.4 billion worth of goods and $6.2 billion worth of services to India, according to the Trade Commissioner Service.
