India will reopen visa services for Canadians, its embassy in Ottawa announced Wednesday, a move that could ease tensions between the two countries triggered by the killing of a Sikh separatist on Canadian soil.

"After a considered review of the security situation that takes into account some of the recent Canadian measures in this regard, it has been decided to resume visa services," the Indian High Commission said in a statement Wednesday.

Canadian Emergency Preparedness Minister Harjit Sajjan welcomed the resumption, saying the two countries had "strong people to people ties" and that it was important for people to be able to go back and forth, for example, for weddings or funerals.

Canada's population features 1.4 million people of Indian origin.

Relations between India and Canada plunged after Prime Minister Justin Trudeau last month publicly linked Indian intelligence to the killing of Canadian citizen Hardeep Singh Nijjar in June. New Delhi dismissed the allegation as "absurd."

Nijjar, who advocated the creation of a separate Sikh state carved out of India, was wanted by Indian authorities on charges of terrorism and conspiracy to commit murder.

Canada has called for India to cooperate in the investigation into his death and expelled an Indian diplomat.

New Delhi expressed outrage, and reacted by taking countermeasures that included shutting down visa services for Canadians.

The Indian government had also advised its nationals not to travel to parts of Canada "given the increase in anti-Indian activities."
