With every passing day, the relationship between India and Canada is getting more strenuous. Canadian Prime Minister Justin Trudeau has been getting a lot of backlash in the world, and also in his own country about his handling of the Khalistan Issue.

Now, with his fresh statement, he has drawn more criticism as he is blaming India for the assassination of the pro-Khalistan leader Hardip Singh Nijjar in June.

Canada has now expelled a top Indian diplomat as it investigates what Prime Minister Justin Trudeau called credible allegations that the Indian government may have had links to the assassination in Canada of a Sikh activist, according to a report published by the Associated Press.

In Parliament, the Canadian PM said the country's intelligence agencies have been investigating the allegations after Sikh leader Hardeep Singh Nijjar was gunned down on June 18 outside a Sikh cultural center in Surrey, British Columbia.

Trudeau further said that he brought up the slaying with his Indian counterpart Narendra Modi at the G20 Summit last week. “I told PM Modi that any Indian government involvement would be unacceptable and asked for cooperation in the investigation."

Canada and India are tense. Trade talks have been derailed and Canada just canceled a trade mission to India that was planned for the fall.

Currently, Canada has a Sikh population of more than 770,000, or about 2% of its total population.

“Over the past number of weeks Canadian security agencies have been actively pursuing credible allegations of a potential link between agents of the government of India and the killing of a Canadian citizen, Hardeep Singh Nijjar," Trudeau said as quoted by AP.

The Canadian PM said his government has been working closely and coordinating with Canada’s allies on the case.

The Khalistan movement is banned in India, where officials see it and affiliated groups as a national security threat. But the movement still has some support in northern India, as well as beyond, in countries like Canada and the United Kingdom which are home to a sizable Sikh diaspora, AP reported.
