The deal will focus on enhancing the capacity of pressurised heavy water reactors of India.

Times of India cited Canada’s Foreign Minister John Baird as saying: "The nuclear agreement starts a new chapter in relations with India."

The two nations are planning to cooperate on developing higher capacity nuclear reactors.

The Indian Ministry of External Affairs (MEA) spokesperson Syed Akbaruddin was quoted by Deccan Herald as saying that the Indian Department of Atomic Energy intends to upgrade the nuclear reactors, which are based on the CANDU model, from their current capacity of 200MW to 750MW.

The two nations will also joint host a nuclear security workshop in India which will include about 15 nations.

In 2010, India and Canada signed a nuclear cooperation agreement. This was followed by signing of an agreement in 2013 by Canadian Nuclear Safety Commission and Department of Atomic Energy of India in order to enable export of uranium and other nuclear items by Canadian companies to India.

A statement from the PMO said: "The Prime Minister welcomed close cooperation between India and Canada and expressed satisfaction at comprehensive nature of bilateral ties, including in areas of economic cooperation, agriculture, security, civil nuclear energy, education, and science and technology."
