New Delhi: Promoting violence in Canada is never acceptable, Canadian Ambassador to India Cameron Mackey said on Tuesday, two days after the display of a tableau depicting the assassination of former Prime Minister Indira Gandhi at an event in Greater Toronto. Fresh tension arose in relations.

India has already raised the issue with Canadian authorities.

"The Government of Canada is aware of the further images displayed in Brampton on Sunday. Canada's position is clear: inciting violence is never acceptable in Canada," Mackay said on

The tableau glorifying the assassination of Indira Gandhi was part of a parade that took place in Brampton to mark the 40th anniversary of Operation Bluestar.Operation Bluestar was an Indian Army operation conducted in June 1984 to flush out terrorists, including their leader Jarnail Singh Bhindranwale, from the Golden Temple in Amritsar.

India has been asking Canada to take strict action against Khalistani supporters operating from Canadian soil.

Relations between the two countries came under severe strain following Canadian Prime Minister Justin Trudeau's allegations of "possible" involvement of Indian agents in the killing of Khalistani extremist Hardeep Singh Nijjar in British Columbia in September last year.

New Delhi rejected Trudeau's allegations as "absurd".

India has been saying that the main issue between the two countries is the exemption given by Canada to pro-Khalistani elements operating on Canadian soil.There have been cases of pro-Khalistani elements threatening to harm Indian diplomats.

Days after Trudeau's allegations last year, India asked Ottawa to reduce its diplomatic presence in the country to ensure parity.

After this Canada recalled 41 diplomats and their family members from India.

Nijjar, declared a terrorist by India, was shot dead outside a gurudwara in Surrey, British Columbia on June 18 last year.

The murder is being investigated by the Royal Canadian Mounted Police (RCMP).
