The rising tension between India and Canada is also creating tension for the Indian dispora staying in Canada, especially the Hindu community.

Pro-Khalistani extremists (PKE) have started openly intimidating minority Hindus wit many instances of defacing of temples have been reported, people with direct knowledge of the matter said.

"The open threats by Khalistanis to the physical security of Indian missions and diplomats in Canada is a very serious development and challenges the obligation of Canada under the Vienna Convention," a senior government officer who's closely monitoring the situation said, requesting anonymity as reported by NDTV.

It appears there are different scales for measuring human rights, the officer said.

"Voices from Canada are very strong on even trivial issues in Punjab, while there has been a complete silence on intimidation, violence, drug trafficking and extortion by PKEs sitting in Canada, affecting both countries," the officer added.

All these issues were discussed in a high-level meeting of intelligence agencies today, people familiar with the matter said.

The issues discussed included the soft-pedalling of Khalistanis, which ensured that moderate and pro-India Sikhs were thrown out of all big gurdwaras in Canada by the muscle and money power of the PKEs.

Dossiers maintained by the intelligence agencies show Punjab today suffers heavily because of extortion rackets run from Canada.

Canada-based gangsters bring drugs from Pakistan through drones and sell across Punjab. A part of this money goes back to Khalistani extremists in Canada.

"Over a period of years, Khalistani extremists got further emboldened and started operating with impunity from Canada. In the last decade, links of Canada-based Khalistani extremists have emerged in more than half of the terror cases reported from Punjab," an intelligence report stated.

"But, Canadian agencies did not show any urgency in finding the real people behind it and unravelling the real conspiracy. Two local criminals who were not of Indian origin were only charged in the case," it stated.
