The two NSAs prepared the ground for Trudeau and Prime Minister Narendra Modi to intensify defence and security cooperation, and India's concerns over rising Sikh radicalism in Canada are understood to have figured in the meeting held a couple days back, Canadian diplomatic sources indicated.

The negotiators of both the countries met last week to overcome the hurdles in finalising the pact, the sources said, adding Canadian investments in India were around USD 15 billion in the last couple of years, and a free trade pact will further encourage investors from that country.

Sources said the objective of the Canadian prime minister's visit here would be to expand overall ties between the two countries with a focus on defence and security, counter-terror cooperation, trade and investment and tackling climate change.

Both sides are also expected to deliberate on enhancing cooperation in civil nuclear sector.

A number of Trudeau's cabinet colleagues including Foreign Minister Chrystia Freeland, Science and Economic Development Minister Navdeep Bains, Defence MInister Harjit Singh Sajjan, Science and Sports Minister Kirsty Duncan and Infrastructure Minister Amarjeet Sohi are also visiting India.

When referred to Punjab Chief Minister Amarinder Singh calling Canadian Defence Minister Sajjan as "Khalistani sympathiser" ahead of his visit here last year, the diplomatic sources called the remarks "disappointing and inaccurate".

"This will be an opportunity for the prime minister to promote Canada-India cooperation on a range of issues and highlight Canada's support for a strong, united, diverse India and to further strengthen the vibrant strategic partnership," said a Canadian diplomatic source.

Besides his engagements in Delhi, Trudeau will visit Agra, Ahmedabad, Mumbai and Amritsar.

Officials said Trudeau's his visit to Gujarat will be first by a Canadian prime minister.

Trudeau, who will be accompanied by his wife and three children, is schedule to visit Taj Mahal on February 18, and next day he will travel to Ahmedabad where he will visit Sabarmati Ashram. He will visit Akshardham temple in Gandhi Nagar and participate at an event at IIM-Ahmedabad.

On February 20, he will visit Mumbai where he will hold meetings with top business leaders and meet representatives of Indian Film industry to explore various opportunities in the field of cinema.

On February 21, the Canadian PM will travel to Amritsar where he will visit the Golden Temple. He will return to Delhi the same day.

Trudeau is scheduled to visit Jama Masjid and a cricket ground here on February 22 besides delivering a lecture at a gathering of Canadian and Indian business leaders.

He will hold wide-ranging talks with Prime Minister Modi on February 23.

The next day, he is scheduled to address a conference of young change-makers before wrapping up his visit.

India is also expected to raise the concern over rising Sikh radicalism in certain parts of Canada.

On trade, the media reports said that Canadian investments in India were likely to decline in absence of a mechanism to protect them.

Besides meeting PM Modi, Trudeau accompanied by his wife and three children will also visit Agra, Ahmedabad, Mumbai and Amritsar.
