This is the best summary I could come up with:

The Canadian government has amassed both human and signals intelligence in a months-long investigation of a Sikh activist's death that has inflamed relations with India, sources tell CBC News.

In a diplomatic crisis that unfolded progressively behind the scenes, Canadian officials went to India on several occasions seeking cooperation in the investigation of Hardeep Singh Nijjar's death.

"I can assure you that the decision to share these allegations on the floor of the House of Commons … was not done lightly," Trudeau said Thursday in New York after attending the United Nations General Assembly.

When asked about the intelligence reports, Deputy Prime Minister Chrystia Freeland said she couldn't comment without risking the investigation and Canada's obligations to its Five Eyes partners.

"That partnership rests very much on those… intelligence conversations being held in confidence," she told CBC News Network's Power & Politics host David Cochrane.

Asked if Ottawa is thinking about retaliating by pausing visa processing for Indian visitors, Freeland said the government is focused on bringing the killers to justice.
