However, speaking out on the issue, Canadian PM Justin Trudeau on Thursday said that obviously, we take this extremely seriously.
Canadian Member of Parliament (MP) Randeep S. Sarai took responsibility for inviting Atwal to Trudeau's reception dinner in New Delhi, which is scheduled to take place later today.
"They still didn't vet everybody properly and they allowed a former violent Khalistani access to the delegation", Dosanjh said. So, as far as the security point of view, we can not say that he has flouted any law by entering the country, " said an MHA official.
But Atwal told Postmedia that he does not plan to attend the dinner as he is in Mumbai on business. Atwal was formerly part of the International Sikh Youth Federation (ISYF), which seeks to establish Khalistan, an independent Sikh state in the Punjab region.
The Canadian government's conduct with regard with Khalistani extremism has always been fairly disgraceful; but it is useful to remind ourselves that India and in particular, Punjab, have not covered themselves with glory.

However, home ministry sources said that his entry into the country was not illegal as he had been taken off the MHA's blacklist after a review by the security agencies and state government a few years ago. A judge called it an act of terrorism and sentenced Atwal and three others to 20 years in prison.
Sidhu was struck twice and survived the attempt on his life, but was later assassinated in India.
However, photographs of Atwal sharing space with Trudeau's wife emerged in Canadian media triggering a fresh debate.
In 2010, Atwal was convicted in an automobile fraud case. "Now that The Canadian High Commission has withdrawn the invitation for the dinner (to Atwal) let us not press the issue any further".
"Atwal is a partisan activist in British Columbia and previously held a leadership position in Surrey with the Liberal Party of Canada", the report added. "Here is a picture from my 2015 Canada visit, when I'd met PM Trudeau and Ella-Grace".
Some inveterate optimists believe that these words are the markers of a new beginning, and that the proximate future will see abruptly stringent action against Khalistani formations and sympathisers in Canada.
Last April, Punjab's top elected official, Amarinder Singh, refused to meet Canadian Defence Minister Harjit Sajjan, alleging he was a "Khalistani sympathiser".
