The officials spoke on background Friday to The Canadian Press on condition that their names not be used, even as Conservatives and New Democrats demanded investigations by a House of Commons committee and the federal ethics commissioner into allegations that Wilson-Raybould was pressured by Prime Minister Justin Trudeau's office to help SNC-Lavalin avoid prosecution.
SNC-Lavalin faces legal trouble over allegations it paid millions of dollars in bribes to obtain government business in Libya, which would be a crime under Canadian law.
The Globe and Mail never reported that officials in Mr. Trudeau's office had directed Ms. Wilson-Raybould to take action - only that she was pressured to do so and declined.
According to the Globe's story, the Prime Minister's Office urged Wilson-Raybould to intervene in a case of corruption against the Quebec engineering and construction company.
Wilson-Raybould was shuffled out of the justice portfolio last month, with Trudeau naming her veterans affairs minister.
Neither Trudeau nor Wilson-Raybould nor SNC-Lavalin has immediately responded to questions from The Canadian Press about the story.
"If the Prime Minister has nothing to hide as he has suggested, then he should have no reason to fear these individuals appearing before the justice committee", Scheer said on Friday.
Wilson-Raybould's father, Bill Wilson, said in a Facebook post Thursday that his daughter's cabinet demotion "makes sense now - ugly political sense".
The former federal attorney general is refusing to either sink or protect her prime minister - but it's clear the days of hugs and mutual admiration tweets are history.
"Neither the current nor the previous attorney general was ever directed by me or anyone in my office to take a decision in this matter", he said.
Meanwhile, the NDP is also calling for the ethics commissioner to investigate the allegations, as is Ottawa-based ethics watchdog Democracy Watch.
On Friday, she released a short statement saying she was "bound by solicitor-client privilege in this matter", though some lawyers were quick to argue that the prime minister could easily waive that privilege if he wanted Wilson-Raybould to speak openly.
The federal director of public prosecutions is officially asking a court to toss out a plea from SNC-Lavalin to spare the company from criminal proceedings.
The company said it provided the prosecutor's office with information showing the objectives of the remediation provisions were "easily met", including details of SNC-Lavalin's efforts to implement a world-class ethics and compliance program, as well as the complete turnover of the company's senior management and board of directors.
"The allegations that we are hearing in the last 24 hours are unprecedented", Scheer said.
"At the end of the day, Canadians deserve to have a government on their side, on the side of justice, not on the side of a multinational corporation".
In its October 19 submission to the Federal Court, SNC-Lavalin said while the public prosecutor has discretion to decide whether to open negotiations on a remediation agreement, this discretion "is not unfettered and must be exercised reasonably" under the law.
Justin Trudeau denied a report that members of his staff urged Canada's former justice minister to intervene in a legal case involving SNC-Lavalin Group Inc.
The fact that such directives must be done publicly would seem to constrain a justice minister from doing anything overtly political.
