New Delhi on Monday summoned Canadian Deputy High Commissioner over raising of separatist slogans on 'Khalistan' at an event addressed by Canadian Prime Minister Justin Trudeau, underlining that it impacts the relations between the two countries and encourages "climate of violence". "The Government of India's deep concern and strong protest was conveyed at such disturbing actions being allowed to continue unchecked at the event. This illustrates once again the political space that has been given in Canada to separatism, extremism and violence," said the Ministry of External Affairs in a statement.
