The Prime Minister also reiterated his previous claims that he did not "direct" Wilson-Raybould to take any action in the SNC Lavalin case requesting a remediation agreement.
Wilson-Raybould has only said that she can not comment on the matter, since she is bound by solicitor-client privilege, since the allegations came to light.
Jody Wilson-Raybould resigned from the federal cabinet this week, leaving unanswered questions about whether Trudeau's aides leaned on her to help engineering firm SNC-Lavalin avoid criminal prosecution.
SNC-Lavalin employs about 9,000 people at its Montreal office. "But as we do that, we always need to make sure we're standing up for the rule of law and protecting the independence of our justice system", Trudeau said.
The comments are Trudeau's widest-ranging yet in a controversy that has rocked his administration.
When former prime minister Stephen Harper's office was caught up in a scandal involving housing expenses from Conservative Senator Mike Duffy, Harper immediately waived this privilege to allow for an open and transparent investigation. "It was concerned about creating jobs, having a solid economy and also protecting jobs in Canada".
Placing the ball back in Wilson-Raybould's court, Trudeau said "If the minister or anyone else felt undue pressure, it was their responsibility to come forward". He explains why the case could be made that "there's nothing to see here", since the minister of justice had the final word.
At the news conference, Trudeau continued to pass the issue to Wilson-Raybould.
"In terms of giving any direction she asked me if I would do that and I said no, absolutely not".
MaryAnn Mihychuk, who served with Wilson-Raybould in cabinet until January 2017, said neither Trudeau nor his staff ever pressured her when she was minister of Employment, Workforce Development and Labour.
I was delighted when Trudeau appointed her to his cabinet, and I was shocked and disbelieving when she was shunted aside. "I had full confidence in her role as attorney general to make the decision", he said.
The prime minister said there were "obviously" many discussions unfolding around the company, including questions asked of him by two different Quebec premiers, representatives of the company, MPs, and a range of individuals.
While there will a process to get answers for her departure through the House of Commons justice committee and ethics commissioner, Bellegarde says the Liberals must push critical pieces of legislation, including a recently tabled bill on Indigenous languages and a proposed bill on child welfare.
