The company was facing allegations of corruption involving government contracts in Libya.
A conviction could result in a decade-long ban on bidding on Canadian federal contracts, which would be a major financial hit for the firm. The company's stock plunged the most in six years October 10 when it revealed that the Public Prosecution Service of Canada ruled out a negotiated settlement that would have staved off a trial.
She presented damning evidence, based on verbatim texts, contemporaneous notes, and detailed personal recollections, of "a consistent and sustained effort by many people within the government to seek to politically interfere in the exercise of prosecutorial discretion in my role as the attorney general of Canada in an inappropriate effort to secure a Deferred Prosecution Agreement with SNC-Lavalin".
Trudeau has denied that the SNC-Lavalin affair had anything to do with Wilson-Raybould's being moved out of the justice portfolio in January.
"Neither I nor any members of my staff had put any pressure on the attorney general to end the criminal prosecution on SNC-Lavalin", he told a press conference.
I cringed knowing that the second the hearing ended I would go online and see people calling her a liar and a traitor, blame her if a conservative government were to take power, and generally posting a host of bad things.
What does the former attorney general say?"I would strongly advise against it".
He also said Wilson-Raybould said no laws were broken and she wasn't directed.
One member of the committee asked Wilson-Raybould if she still had confidence in the prime minister, and she was cautious in her response.
The former AG says Trudeau and his staff spent months trying to convince her that taking the company to trial would cost Canadians jobs, and their party votes.
The head of the federal civil service, according to Ms Wilson-Raybould, told her Mr Trudeau would "find a way to get it done one way or another".
Butts resigned from the PMO on February 18 amid allegations he and others exerted political interference on Wilson-Raybould to override the Public Prosecution Service director's decision to prosecute SNC-Lavalin.
In almost four hours of testimony that was meticulously prepared, deeply detailed, unflappably delivered and impenetrable to those who sought to challenge its substance, Ms. Wilson-Raybould succeeded in presenting herself as someone who should be believed.
On Thursday, at an announcement for the Canada Space Agency, Trudeau reiterated that he had done nothing wrong, and was simply doing everything he could to preserve the economy. "We've also done it in a way that has respected our laws, and respected the independence of the judiciary - of that there actually is no doubt". Wilson-Raybould disagreed, saying she found the pressure inappropriate, if legal.
The day before, Canada's opposition leader, heading the Conservative Party, called on Trudeau to resign. "We know that there are many factors that go into decisions like that", Trudeau said in Saint-Hubert, Quebec.
Trudeau said he welcomed an investigation by the ethics commissioner "to clear the air on this matter".
In Wednesday's response, Trudeau reiterated the decision surrounding SNC-Lavalin was Wilson-Raybould's to make and that they had conversations of the potential loss of 9,000 jobs and pensions.
Conservative Leader Andrew Scheer, who is Trudeau's top rival, demanded the prime minister step down over the revelations.
"My job as prime minister is to stand up for jobs. So, he is in that kind [of] mood and I wanted you to be aware of that".
"For Indigenous people, we know that these systems - whether it's university or politics - were not made for us", said Lariviere, who is Métis and Filipino.
"It is troubling because I very deeply believe in our institutions".
