Asked Friday why he did not apologize to her or Philpott for his handling of the affair, Trudeau said: "I do regret it happened, clearly, and I have made a commitment to learn from it". The information Wilson-Raybould and Roussel used to make their decisions has not been made public.
Saying he has taken many lessons from the recent "tough" weeks, Trudeau announced the administration will seek external expert opinions on the issues raised.
"I was not aware of that erosion of trust, and as prime minister and head of cabinet, I should have been", Trudeau said during a news conference in Ottawa.
However, it is not the first time the NDP has criticised Mr Trudeau for his lack of accountability and it is also not the first time the Canadian has been at the centre of controversy. His statement comes after another Liberal minister resigned this week in the wake of testimony that the prime minister and senior staff tried to politically interfere in a corruption trial.
"What they are seeing in this context is the result of disagreements internally on the best ways to proceed", he said, later adding, "I can repeat and reassure Canadians that there was no breakdown of our systems, of the rule of law, of the integrity of our institutions". Wilson-Raybould told the House of Commons justice committee last week that officials imposed "consistent and sustained pressure" on her from September to December a year ago to ensure SNC-Lavalin pay a large fine rather than go to trial.
SNC-Lavalin, which employs 9,000 people in Canada, was seeking a deferred prosecution agreement to allow the firm to escape with a fine. It was that he - and his PMO - didn't put inappropriate pressure on the then-attorney-general, but he understands now that she felt differently.
But the way Wilson-Raybould described it during her testimony, she had made it clear at the time that she would not be changing her mind.
But he added, Wilson-Raybould also should have been more forthcoming with her concerns. "She did not come to me, and I wish she had", he said.

In both instances, it says more about the evaluator and their discomfort with powerful women than it does about the woman herself. People are not meant to move at supersonic speeds at all, let alone at the angles Danvers and Cobb's battle involves.
"It is our job as parliamentarians to defend the interests of the communities we were elected to represent, to be the voices of those communities in Ottawa", Trudeau said.
Lavalin is a major employer in Quebec and Trudeau's pressure on Wilson-Raybould was justified, he says, because thousands of jobs were at stake.
After all that, Trudeau said the testimony has revealed a "difference in perspective" on conversations that took place "among colleagues about how to tackle a hard issue".
The prime minister said he didn't realize at the time that Wilson-Raybould had "reconfirmed her decision for herself" after their meeting, and was not open to further discussions on the matter. In 2016, SNC-Lavalin admitted that some former executives had illegally arranged donations of more than C$80,000 to the Liberals from 2004 to 2011.
Wilson-Raybould refused, and was shuffled out of the Justice portfolio and into Veterans Affairs in January.
Butts offered "persuasion" as another word.
The prime minister also came close to admitting that he had made a mistake in repeating the practice of his predecessors, going back to his father's time, of creating a almost all-powerful secretive, unaccountable and unelected PMO.
"I asked my staff to follow up regarding Ms. Wilson-Raybould's final decision. She said that she would", he said of a September 17, 2018, meeting. According to the rules of parliament, if four members of a committee submit a request, the chair of the committee must call for it to meet, as long as they're given 48 hours' notice.
