He urged Liberal MPs to "speak truth to power" - a reference to Wilson-Raybould's infamous statement after she was removed as attorney general - and send a signal that Trudeau "is not entitled to be the prime minister of Canada".
"Her and Philpott's resignations also carry the optics of a fledgling political version of the "#MeToo" movement developing in Canada whereby at least one prominent female politician felt so strongly about supporting Wilson-Raybould that she even left her position ahead of this year's elections knowing how negatively it could impact on her party and especially Trudeau personally.
The official, Jody Wilson-Raybould, later alleged in testimony before the House Justice Committee that she faced "veiled threats" and "sustained" pressure to help Montreal-based SNC-Lavalin.
"I will be making an Inuit apology this afternoon", said the prime minister, referring to his upcoming visit to Iqaluit to apologize for government mistreatment of Inuit during tuberculosis epidemics in the mid-20th century. "They've worked very, very, hard and I think it's important to recognize that work and recognize that they want to play a different role", she said.
The Federal Court of Canada on Friday dismissed a request by SNC-Lavalin to review a federal prosecutor's decision declining to settle criminal charges against the company out of court.
A DPA could allow SNC-Lavalin to pay a fine in lieu of a criminal conviction, which would bar it from bidding on federal contracts.
Addressing the media, the 47-year-old premier acknowledged he raised the pending trial during a meeting last September with then attorney general Jody Wilson-Raybould - whose resignation touched off the crisis.
"But, in regards to standing up for jobs and defending the integrity of our rule of law, I continue to say that there was no inappropriate pressure", regarding the SNC-Lavalin scandal.
"There was no inappropriate pressure", he said, adding "that the decision was hers alone". "Indeed, I expect them to do so", he continued.
Saskatchewan Premier Scott Moe took aim Thursday at the prime minister's comments about 9,000 jobs tied to the Quebec company. Wilson-Raybould and her cabinet ally, Treasury Board president Jane Philpott, resigned from cabinet in the wake of the controversy.
SNC-Lavalin faces legal trouble over allegations it paid millions of dollars in bribes to obtain government business in Libya - a case that has prompted a political storm for the Trudeau Liberals. As part of their campaign, some "urged me to take partisan political considerations into account", she said.
"As we look back over the past weeks, there are many lessons to be learned and many things we would have liked to have done differently", he said, adding he should have been aware Ms Wilson-Raybould was unhappy.
Wilson-Raybould, unexpectedly demoted to the veterans affairs ministry in January, quit on February 12. And he did hold out an olive branch to the former ministers when asked how they can remain in the Liberal caucus and run for the Liberal party in this fall's election, given their lack of confidence in his leadership. The Liberals have been claiming if SNC doesn't get a deal that it will leave Montreal, this despite a financing agreement with Quebec's pension fund manager, the Caisse de dépôt, that requires the company to keep its headquarters in that city until at least 2024.
The incident came to light after the Globe & Mail published a report alleging that Trudeau's office had pressed the attorney general in the hopes of getting the criminal charges against the engineering firm dropped.
