Canadian Prime Minister Justin Trudeau on Thursday called on India to cooperate with an investigation into the murder of a Sikh separatist leader in British Columbia and said Canada would not release its evidence.

Trudeau said on Monday that Ottawa had credible allegations linking Indian government agents to the murder of Hardeep Singh Nijjar in June, prompting an angry reaction from New Delhi. Nijjar, 45, was a Canadian citizen.

Traditional Canadian allies have so far taken a relatively cautious approach to the matter. Analysts says this is partly because the United States and other major players see India as a counterweight to the growing influence of China.

“There is no question that India is a country of growing importance and a country that we need to continue to work with … and we’re not looking to provoke or cause problems,” Trudeau said in a press conference in New York on the sidelines of the United Nations General Assembly.

“But we are unequivocal around the importance of the rule of law and unequivocal about the importance of protecting Canadians.”

“That’s why we call upon the government of India to work with us to establish processes to discover and to uncover the truth of the matter.”

The Indian foreign ministry said Canada had not shared any specific information about the murder. Nijjar supported a Sikh homeland in the form of an independent Khalistani state and was designated by India as a “terrorist” in July 2020.

“As a country with a strong and independent justice system, we allow those justice processes to unfold themselves with the utmost integrity,” Trudeau replied when asked when Canada would release the evidence it had.

India suspends visas for Canadians

Earlier today, India suspended new visas for Canadians and asked Ottawa to reduce its diplomatic presence in the country.

The Indian foreign ministry said Canada has not shared any specific information in connection with the allegations Trudeau made and that New Delhi was willing to look at it if provided.

A blanket suspension of new visas by India for a Western country is unheard of and marks the lowest point of India-Canada relations.

The announcement came hours after Canada’s high commission in India said it would temporarily “adjust” staff presence in the country after some diplomats received threats on social media platforms.

But Indian foreign ministry spokesperson Arindam Bagchi said Ottawa had been asked to reduce numbers at its diplomatic missions in India to bring parity between the missions of the two countries.

Bagchi said India suspended issuing new visas to Canadian citizens due to “security threats” to its staff in its consulates in Canada.

India has not provided any evidence or given details of the nature of such security threats, and Canada’s public safety minister Dominic LeBlanc said in response on Wednesday that Canada was a safe country.

“You are aware of the security threats being faced by our high commission and consulates in Canada. This has disrupted their normal functioning,” Bagchi told reporters at a weekly briefing on Thursday.

“Accordingly our high commission and consulates are temporarily unable to process visa applications,” he said, adding that the security situation would be reviewed regularly.

Canada is the fourth largest source of foreign tourists with 350,000 visitors in 2019, a number which fell following the Covid-19 pandemic, according to Indian government data.

‘Risk to reputation’

The unprecedented tensions flared up on Monday after Trudeau said Ottawa was investigating “credible allegations” about the potential involvement of Indian government agents in the June murder of Hardeep Singh Nijjar in British Columbia.

Prime Minister Narendra Modi’s government denied any links to the alleged murder.

Canadian officials have so far declined to say why they believe India could be linked to Nijjar’s murder.

The two countries, whose relations have been fraying in recent years over the issue of Sikh separatists, have since announced tit-for-tat expulsions of senior diplomats and issued tit-for-tat travel advisories.

Bagchi said India was “willing to look at any specific information, we have conveyed this to the Canadian side, made it clear to them…but so far, we have not received any such specific information”.

Canada has discussed the issue with key allies such as the Five Eyes intelligence sharing alliance, which includes the United States, Britain, Australia and New Zealand, with Washington, London and Canberra expressing concern.

Asked if any of these countries, with whom India also enjoys close ties, had raised the issue with New Delhi, Bagchi said: “We have been discussing with them, we have conveyed our position how we see these developments.”

Bagchi also said Canada should be worried about damage to its reputation and not India, when asked about the risk posed by the row to New Delhi’s global standing.

“If there is any country that needs to look at it, it is Canada, its growing reputation as a safe haven for terrorists, extremists and for organised crime,” he said, adding that India had in vain sought action against more than 20 individuals.

Threat to trade ties

Canada has the largest population of Sikhs outside the northern Indian state of Punjab, with about 770,000 people reporting Sikhism as their religion in the 2021 census.

A bloody Sikh insurgency in the 1980s and 1990s in Punjab killed tens of thousands of people before it was suppressed. The separatists wanted the creation of an independent Sikh state called Khalistan.

Although there is hardly any support for the insurgency left in India, small groups of Sikhs in Australia, Britain, Canada and the United States support the separatist demand and occasionally stage protests outside Indian embassies.

New Delhi, which remains wary of any revival of the insurgency, has long been unhappy over Sikh separatist activity in Canada.

Some Indian analysts say Ottawa does not curb Sikh protesters as they are a politically influential group.

The spat is also threatening trade ties, with talks on a proposed trade deal frozen last week.

Canada is India’s 17th largest foreign investor, while Canadian portfolio investors have invested billions of dollars in Indian financial markets.

Since 2018, India has been the largest source country for international students in Canada, with their numbers rising 47 per cent in 2022 to nearly 320,000.

Industry estimates show the Comprehensive Economic Partnership Agreement (CEPA) between Canada and India could boost two-way trade by as much as $6.5 billion.
