Trudeau, key election players to testify at foreign interference hearings. What you need to know

The public hearings portion of the federal inquiry into foreign interference in Canadian elections and democratic institutions are picking back up this week.

Over the next few weeks, the first substantive public phase of the national probe will include high-profile testimony, including from Prime Minister Justin Trudeau.

After months of behind-the-scenes preparations, including deciding which key players will be able to participate and establishing parameters for the national security and intelligence-centric process, commissioner Marie-Josee Hogue presided over the first set of preliminary public hearings from Jan. 29 to Feb. 2.

After this upcoming set of hearings wrap up, Hogue will have less than a month to present her interim report.

Here's what you need to know. 

Who will be testifying?

Staring March 27 and continuing until April 10, the commission will hear from more than 40 witnesses, including the prime minister, a series of cabinet ministers, top staffers in the Prime Minister's Office (PMO), key political party employees, and Elections Canada officials.

This phase of hearings will focus on "foreign interference that may have occurred in the 2019 and 2021 federal elections, any potential impacts on the integrity of those elections, as well as the flow of information to senior decision-makers during the election periods and the weeks following, and actions taken in response," according to the inquiry.

The hearings are expected to last close to eight hours a day, and first up will be diaspora community members, followed by Elections Canada Chief Electoral Officer Stéphane Perrault, as well as a series of other top voting officials.

As the hearings go on, the inquiry will hear from party brass from the Liberal, Conservative, and NDP campaigns, as well as current and former MPs Han Dong, Erin O’Toole, Jenny Kwan, and Michael Chong.

Then, in early April, Hogue will be hearing testimony from top federal officials and the prime minister. While the commission has yet to unveil the full schedule detailing who will be in the hot seat and when, here's some of the biggest names expected to appear:

Cabinet ministers Dominic LeBlanc, Karina Gould, and Bill Blair; senior members of the Privy Council Office, including former head Janice Charette; top PMO staffers including Brian Clow and Katie Telford; and CSIS and RCMP leaders. 

What prompted this?

A national public inquiry into allegations of attempted foreign election interference was a move the federal Liberal minority government came to, reluctantly, last fall.

After extensive deliberations, parliamentary hearings and a failed special rapporteur process, minister LeBlanc announced in September that a Quebec Court of Appeal justice would take on the task of examining the issue.

While concern around potential meddling in the 2019 and 2021 federal campaigns — based in part on media reports citing unnamed intelligence sources and leaked documents — was what kicked off this controversy, the inquiry has been given a broader mandate.

What is the inquiry's scope?

While the first phase of Hogue's work is focused on "the interference that China, Russia and other foreign actors may have engaged in" during the last two elections, it will also dig into the flow of information within the federal government in connection with these alleged instances.

The inquiry has also requested information and documents from the federal government regarding alleged interference by India in connection to the 2019 and 2021 elections.

Overall, the examination will include assessing the flow of information within the federal government, including communications between elected officials, the Security and Intelligence Threats to Elections (SITE) Task Force and the Critical Election Incident Public Protocol panel during the lead up to, and through, the 43rd and 44th general elections, and in the weeks following. 

Who knew what, who was alerted at the time and how the suite of responsible federal security agencies handled these meddling threats have all been questions central to the examinations previously undertaken by parliamentarians on this file.

The second phase of the public inquiry will focus on the federal government's capacity and capabilities to "detect, deter and counter such interference." This second more forward-looking portion is meant to help Canada shore up its democratic processes against future threats as the next federal election approaches.

What is the timeline?

The first set of public hearings began Jan. 29 in Ottawa with an opening statement by Hogue.

This round of "preliminary" hearings carried over five days and focused on "the challenge of making as much of the information received by the Commission as possible public."

Among those on the witness list for week one were national security expert professors, former CSIS director Richard Fadden, current CSIS director David Vigneault, deputy chief of signals intelligence at the Communications Security Establishment (CSE) Alia Tayyeb, and deputy national security and intelligence adviser Dan Rogers.

The commission then took a pause on public hearings until this week's resumption.

After raising concerns with the overall condensed timeline that would have required Hogue to submit an interim report by Feb. 29, the commissioner was granted an extension to May 3.

"The purpose of this postponement is to give meaning and purpose to the preliminary hearings, and to allow more time to maximize the transparency of the Commission's work," commissioner Hogue said.

A third set of hearings, related to the second phase of the inquiry's mandate, is tentatively scheduled to begin in September 2024.

"These hearings will focus on the federal government’s capacity to detect, counter, and deter foreign interference targeting Canada's democratic and electoral processes, and the related supports and protections in place for diaspora community members, pursuant to paragraph," according to the commission.

Hogue's final report is due to the government, in both official languages, by Dec. 31, 2024.  

Who are the key players?

While Hogue is playing the lead role in this process, she is accompanied by lead counsel for the commission Shantona Chaudhury.

If that name sounds familiar, it's because Chaudhury was one of the Public Order Emergency Commission's (POEC) co-counsels who spent weeks questioning witnesses in open hearings about the Emergencies Act invocation.

Hogue has said Chaudhury will lean on her national security law expertise in leading the team hired to conduct the foreign interference probe. Included in this team are senior policy advisor Paul Cavalluzzo, who was lead counsel for the inquiry into the Maher Arar matter, and research counsel Genevieve Carter, who played a similar role during the Charbonneau Commission.

There is also the entire roster of parties and individuals that have been granted "standing" and will play a role in this process.

Among those Hogue has approved to participate in some capacity during either both or one of the phases of the inquiry are the federal Conservative and New Democratic parties, Conservative MP Michael Chong, Liberal-turned-Independent MP Han Dong, and former Conservative MP and past leader Erin O'Toole.

A number of organizations representing Chinese, Russian, Ukrainian, Iranian and Indian diaspora groups were also given the ability play a role, as was a joint "media coalition" and a coalition of former intelligence officials.

Can Canadians participate?

The public has been invited to attend the commission's hearings in-person at 395 Wellington Street in Ottawa, but the proceedings are also be available to stream on the inquiry's website. 

The commission also has a process for the public to submit information to the inquiry, including providing observations, suggestions and relevant experience.

As part of this, the commission has promised, if needed, to put proper identity protections in place.

The inquiry has designated a specific confidential email address that can be used to transmit information, in confidence: [e-mail]

What are the limitations?

The balance between providing the public transparency, and protecting classified intelligence, is already proving to be a delicate issue the inquiry is grappling with.

The spring decision by then-special rapporteur David Johnston not to recommend an inquiry cited the inability to satisfy the concerns of Canadians due to the national security limitations on making key details public.

Hogue has said she's mindful of this challenge but has vowed the inquiry is "committed to accomplishing its mandate with independence, impartiality, fairness, thoroughness, expedition, proportionality, and transparency."

Minister LeBlanc has said it will be up to Hogue to determine which aspects of the inquiry are public versus in camera, or behind closed doors, and has vowed the commission will have "full access" to all relevant cabinet documents.

"She will in her judgment, based on the legal advice the commission would receive from the commission lawyers … decide how and what hearings will be made public."
