The Indian government will "naturally oppose any move giving political space to extremism and advocacy of violence", the Foreign Ministry said Friday in its weekly press briefing.
The reference was to the Canadian parliament observing a moment of silence in the memory of Khalistani terrorist Hardeep Singh Nijjar, who was shot and killed outside a gurdwara in Canada's British Columbia province last year. He was wanted in India for being the "mastermind" of the Khalistani Tiger Force, a designated terror group in this country.
Canada Prime Minister Justin Trudeau had alleged "agents" of the Indian government were involved in killing Nijjar, who was a Canadian citizen. Those allegations, repeated frequently by Mr Trudeau since, have led to tense relations between the two nations, including awkward moments between the Canadian leader and Prime Minister Narendra Modi when India held the G20 Summit last year.
India has firmly rubbished Canada's allegations, calling them "absurd" and "motivated" and noting that Mr Trudeau has yet to provide evidence, of any sort, to back his claim.
"Such unsubstantiated allegations seek to shift the focus from Khalistani terrorists and extremists… who have been provided shelter in Canada and continue to threaten India's sovereignty and territorial integrity. Inaction of Canada is a matter of continuing concern," the Indian side had side.
Last July, anti-terror agency NIA announced a cash reward of Rs 10 lakh for the capture of Nijjar in connection with the murder of a Hindu priest in Punjab's Jalandhar.
Nijjar is also accused in the 2007 bombing of a cinema in Punjab.
