On September 18, 2023, Trudeau accuses India's government of involvement in killing of Canadian Sikh leader states
"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 Monday in a speech to the House of Commons.
"Any involvement of a foreign government in the killing of a Canadian citizen on Canadian soil is an unacceptable violation of our sovereignty. It is contrary to the fundamental rules by which free, open and democratic societies conduct themselves.
"As you would expect, we have been working closely and co-ordinating with our allies on this very serious matter."
I have also read several other articles (e.g., Canada shared Nijjar killing allegations with India ‘weeks ago,’ Trudeau says and Trudeau declines to offer more evidence on Indian accusations) regarding this statement by Justin Trudeau (Canada's prime minister). However, I am still unclear on what its political purpose was, since it seems to me that it would have been better to keep something like this private.
If this was to try to get the Indian government to co-operate more fully, it seems to have the opposite effect instead. Also, since Trudeau is not doing particularly well in the polls, it might be an attempt to get more support from the Canadian population. This could be from Canadians in general, by showing them the government is standing up for their rights, but I doubt it'll make much difference to most people. More directly, he may be trying to gain support from the Sikh population in Canada, but that is only about 2%. On the other hand, it might anger some of the other East Indian population here, and business people who might be negatively affected by the loss of trade.
Trudeau's statement has caused significant damage to Canada's relations with India. For example, from Trudeau declines to offer more evidence on Indian accusations,
The accusations have set off a tense set of diplomatic moves. Canada began the back and forth by expelling an Indian diplomat, who Foreign Affairs Minister Mélanie Joly said was the chief intelligence official in Canada.
India responded shortly thereafter, expelling a Canadian diplomat from India.
Canada also voluntarily removed staff from the Indian high commission in New Delhi and consulates in the country on Wednesday, citing threats that had been made against embassy staff through social media.
India has also stopped issuing visas for travel between Canada and India.
What political purposes might have been served by Trudeau making that accusation, especially those that counteract the negative consequences summarized above?
