Liberal MP Jody Wilson-Raybould’s gripping testimony before the House Justice Committee on Feb. 27 saw the former minister name a number of political staff involved in meetings and discussions related to SNC-Lavalin, and the role of the attorney general and the public prosecution service. Here’s a rundown of those staff: Gerald Butts, former principal secretary to Prime Minister Justin Trudeau The Hill Times photograph by Cynthia Münster A longtime friend to Prime Minister Justin Trudeau since university and former principal secretary to then-Ontario premier Dalton McGuinty, Gerald Butts had been principal secretary to the prime minister since the Liberals took power in November 2015. He announced his resignation on Feb. 18. While in the PMO, he worked in close coordination with the PMO chief of staff, Katie Telford, in running the top office—with all decisions by the top office said to run past their desks. Mr. Butts is known for being more publicly outspoken, taking to Twitter to engage critics and share his thoughts. He’d been dubbed ‘PM Butts’ by some, and was known to speak with the authority of Mr. Trudeau. Katie Telford, chief of staff to the Prime Minister The Hill Times photograph by Andrew Meade Katie Telford has been chief of staff in the Prime Minister’s Office since November 2015, after running the Liberal Party’s successful 2015 campaign as national campaign co-chair and director. A former Ontario Liberal staffer, Ms. Telford also previously worked in then-Liberal leader Stéphane Dion’s office, was national campaign director for Mr. Trudeau’s 2013 leadership campaign, and is a former senior consultant with StrategyCorp Inc. She was named by Ms. Wilson-Raybould as having been part of meetings with Ms. Wilson-Raybould's then-chief of staff, Jessica Prince, along with Mr. Butts. Among comments attributed to Ms. Telford by Ms. Wilson-Raybould is her having said in a Dec. 18 meeting with Ms. Prince that, "we don't want to debate legalities anymore." Mathieu Bouchard, PMO senior adviser Photograph courtesy of Facebook Mathieu Bouchard is one of two senior advisers currently in the PMO and has been there since November 2015. He’s said to be focused on providing advice on all matters Quebec—for example, he’s tackled the Bombardier file—and is the senior-most Quebecer in the office. Before working for the government, Mr. Bouchard worked as a lawyer in Montreal, last as a partner with Irving Mitchel Kalichman, where he practised civil and commercial litigation. He’s also previously worked for Davies Ward Philipps & Vineberg and is a member of both the Quebec and Ontario bar. As a senior adviser in the PMO, he’s said to act as a liaison for the office with federal lawyers in the Privy Council Office. Elder Marques, PMO senior adviser Photograph courtesy of LinkedIn Elder Marques joined the Prime Minister’s Office in September 2017 and before then had been chief of staff to Innovation, Science, and Economic Development Minister Navdeep Bains since January 2016. He’s also got a background in law—and would also act as a liaison with PCO lawyers—and is a former litigation partner with McCarthy Tétrault in Toronto, where he focused on corporate and commercial disputes, class actions, defamation and professional liability cases, as described in the firm’s 2013 announcement of his being made a partner. He’s also said to have a good rolodex of connections to the business community from his past role in Mr. Bains’ office. Jessica Prince, former chief of staff to then-minister Jody Wilson-Raybould Photograph courtesy of LinkedIn Jessica Prince first began working for then-justice minister Jody Wilson-Raybould as a senior policy adviser in the spring of 2016. After taking leave to travel in the fall of 2017, in June 2018 she returned to the Hill to take over as chief of staff to Ms. Wilson-Raybould. When the minister was shuffled into the veterans affairs portfolio on Jan. 14, Ms. Prince was quick to follow, moving over the same day to take over as chief of staff in Ms. Wilson-Raybould’s new office. She’s frequently been spotted at Ms. Wilson-Raybould’s side since The Globe and Mail’s story broke. Prior to coming to work on the Hill, Ms. Prince was a litigation associate with Polley Faith LLP and with Thornton Grout Finnigan LLP before that. Ms. Prince is currently away on leave. Ben Chin, chief of staff to Finance Minister Bill Morneau Photograph courtesy of LinkedIn Ben Chin was named by Ms. Wilson-Raybould as part of her testimony, including for having emailed Ms. Prince on Sept. 6 to arrange to talk about SNC-Lavalin and having raised the then-ongoing Quebec election during the subsequent talk. A former broadcast reporter, Mr. Chin has been working for Mr. Morneau since October 2017, starting out as a senior adviser; he became chief of staff to the minister in May 2018. He’s a former executive director of communications and issues management to then- B.C. premier Christy Clark, and a former senior communications adviser to then-Ontario premier Dalton McGuinty, among other past roles. Justin To, deputy chief of staff and director of policy to Finance Minister Bill Morneau Photograph courtesy of LinkedIn In her testimony, Jody Wilson-Raybould named Justin To as having been part of a Sept. 20 phone call with Ms. Prince, along with Mr. Chin, about SNC-Lavalin and deferred prosecution agreements. A former deputy director of policy in the PMO, and a finance and economic policy adviser to the PM before that, Mr. To left the top office to work for Mr. Morneau in September 2017. He’s also a former senior policy adviser to then-Liberal leader Michael Ignatieff. Amy Archer, PMO policy adviser Photograph courtesy of LinkedIn Amy Archer was named by Ms. Wilson-Raybould as having received a note also shared with Mr. Marques and Ms. Wilson-Raybould, and sent by her staff, on Sept. 7 on the role of the attorney general. At that point, Ms. Archer would have been brand new to the job, having been hired on as a policy adviser in Prime Minister Justin Trudeau’s office in September 2018. She tackles the justice, public safety, border protection and organized crime reduction, and democratic institutions files. Before joining the PMO, Ms. Archer was a senior policy adviser to then-Ontario attorney general (and Liberal MPP) Yasir Naqvi. She's also a former associate with Lerners LLP and McCarthy Tétrault. François Giroux, judicial affairs adviser in the justice minister’s office François Giroux was named by Ms. Wilson-Raybould as among the ministerial staff in her old justice office who exchanged emails with Ms. Prince and offered advice on the role of the attorney general and having met with the deputy minister for justice. Mr. Giroux remains in place as a judicial affairs adviser in Justice Minister David Lametti’s office, having been hired on to the role in May 2018 under Ms. Wilson-Raybould. Before then, he was working for the federal department of justice. Emma Carver, former litigation and policy adviser to the justice minister Photograph courtesy of Twitter Emma Carver was another of the justice ministerial staff named by Ms. Wilson-Raybould; she was said to have been part of a Sept. 7 meeting with the deputy minister and having helped draft a memo on the role of the attorney general as it relates to the public prosecution service. No longer on the Hill, she worked in the office from September 2016 up until the end of September 2018. Before joining the minister’s office, she’d been a lawyer with Polley Faith LLP in Toronto and has since returned to work at the firm.
