What is the nature of the interference? That is a poorly written article that doesn't say anything on the nature of interference. After all, the fact that the Five Eyes spied on Indian diplomats, and Canadian refusal to handle extremist elements operating out of the country, would make a case for the opposite. By the way, you read the headlines and not the article. So I quote the article.
"On the contrary, India has raised strong protest with the Canadian government against radical Khalistani elements organising referendums in the North American nations and meddling in India's domestic affairs, particularly the farmers' protests.
Despite exhortation from India to act, Prime Minister Justin Trudeau has failed to take action against a new wave of Khalistani activism in Canada.
This is because Trudeau heads a minority government which is backed by the New Democratic Party (NDP), headed by Jagmeet Singh, a Khalistani sympathiser, IANS reported earlier.
Singh's NDP has 24 seats in parliament, whose support is critical for the survival of the Trudeau government.
Singh has been called out time and again on Twitter for attempting to meddle in Indian affairs, especially after he "raised concerns" over the crackdown in Punjab against 'Waris Punjab De' chief and Khalistan sympathiser Amritpal Singh.
According to India Narrative, Singh has long been suspected of attempts to link Khalistani and Kashmiri separatism from his perch in Canada. He is apparently connected with prominent Khalistani and Kashmiri separatist groups based in different countries of Europe, according to media reports."
