March 4 - Jane Philpott, one of Trudeau's most trusted ministers, quits cabinet, saying she has concerns about the pressure Wilson-Raybould described and that she has lost confidence in the way the government has dealt with the ongoing affair.
Jane Philpott stepped down as the president of Canada's Treasury Board on Monday, further escalating the corruption scandal plaguing the prime minister. I must abide by more core values, my ethical responsibilities, constitutional obligations.
"I have been considering the events that have shaken the federal government in recent weeks and after serious reflection, I have concluded that I must resign as a member of Cabinet", Philpott said on Twitter.
"Sadly, I have lost confidence in how the government has dealt with this matter and how it responded to the issues raised", Philpott said in a statement.
Other members of the government, including Finance Minister Bill Morneau and Foreign Minister Chrystia Freeland, said they would stay in the Cabinet.
New Brunswick Liberal MP Wayne Long reiterated his call for a "full and transparent investigation" into the SNC-Lavalin affair.
Conservative leader Andrew Scheer has already called on Trudeau to step down amid the allegations.
Testimony before the justice committee of the House of Commons by Clerk of the Privy Council Michael Wernick and former justice minister Jody Wilson-Raybould revealed a serious clash of wills between Trudeau and Wilson-Raybould about how to deal with corruption charges brought against engineering giant SNC-Lavalin.
Mr Trudeau said he was disappointed by the resignation, but understood it. But Philpott clearly believes her, and doesn't believe him.
Wilson-Raybould was convinced her refusal to help SNC-Lavalin was behind the demotion.More news: "Leaving Neverland": Michael Jackson estate releases concerts while HBO documentary airs

Given that convention, Philpott said, "it is untenable for me to continue to serve as a cabinet minister".
Perhaps the most cutting line in Philpott's letter of resignation was when she declared, "There can be a cost to acting on one's principles, but there is a bigger cost to abandoning them".
She said the administration's senior officials issued "veiled threats" against her in an effort to convince her not to file criminal charges against SNC-Lavalin, the Canadian company that employs about 9,000 people in Canada or 52,000 across the world, according to CBC. The Canadian Prime Minister also thanked her for serving in his Cabinet. For the second time, the cabinet minister has chosen to remain in the Liberal caucus.
Two Liberal legislators voted with the opposition last week in a failed bid to launch a public inquiry, while a female Liberal member of parliament tweeted her support for Wilson-Raybould, adding the hash tag #IStandWithHer.
With another high-profile resignation hanging over his government, a simple question by Prime Minister Justin Trudeau at the beginning of a Liberal party rally on climate change action may have had more than one meaning.
Since the furor erupted a month ago, Trudeau has offered only general denials of any wrongdoing.
Bothwell said Trudeau is not like his father, the late Prime Minister Pierre Trudeau, who swept to office in 1968 on a wave of support dubbed "Trudeaumania" and governed for most of the next two decades.
Trudeau said that "enjoying our natural world is a huge part of the Canadian identity".
"I experienced a consistent and sustained effort by many people within the government to seek to politically interfere in the exercise of prosecutorial discretion", Wilson-Raybould told a parliamentary committee on February 27. There has been some speculation in Liberal circles that Philpott might run for leader of the Ontario Liberal party.
