His comments come after a Canadian Press investigation revealed four officers with the Canadian Security Intelligence Service raised concerns about the toxic culture within the British Columbia office.

One CSIS officer said she was raped nine times by a senior colleague while in surveillance vehicles, while another said she was sexually assaulted by the same man.

The women said they warned their bosses that the man needed to be kept away from young women.

Trudeau, who was in Ajax, Ont., for a separate announcement, said the allegations are of "deep, deep concern."

"These allegations are absolutely unacceptable. We need to make sure that everyone in every workplace, no matter how delicate or sensitive or secret the work is that they are doing is protected, particularly for people who serve their country."

The Canadian Press is not identifying the women who came forward because they fear legal and professional repercussions or retaliation from CSIS if they reveal their identities.

The women say supervisors told them other women had complained about not feeling safe around the man at the centre of the allegations.

“Nothing was done, and I started hearing these stories that there was this history of all these women (who) used to be working at our region. They used to be there, and they all had the same thing to say, and they all just ended up leaving,” an officer said.

Trudeau said his government has taken such allegations "incredibly seriously" since the start.

"And I can assure you that the minister and our entire government is following up very directly on these issues."
