CSIS Flagged a 2019 Liberal Nomination. The Candidate Stayed. Of the Briefing After the Vote, “It Appears That No Documentation Exists.”
The intelligence on the 2019 Don Valley North nomination was never proven, and the candidate denies any role. The warning went from the Panel of Five to the party, and from the party to its leader, who alone had power over the candidacy and kept the candidate. Of the briefing the Prime Minister’s Office asked for after the vote, the inquiry says it appears no documentation exists.

The warning
On 12 September 2019, the Liberal Party held its nomination vote in Don Valley North, a Toronto riding it expected to win Hogue vol. 2, pp. 104, 108. Within weeks, Canada’s spy agency had told the government’s election watchdogs Hogue vol. 2, pp. 106, 110, the Liberal Party, and through the party its leader, the Prime Minister, that a foreign state may have helped pick the winner.
What CSIS reported, in NSICOP’s summary: “between 175 and 200 international Chinese students arrived in several buses,” and “The Consulate reportedly told the students that they must vote for Mr. Dong if they want to maintain their student visas.” NSICOP p. 31 Later intelligence said “veiled threats were issued by the PRC Consulate to the international students.” Hogue vol. 2, p. 104
Read that again for who was threatened: foreign students, told, by the reporting, that their visas hung on a vote. They are the people this story happened to. The story is about the people paid to protect them, and what those people decided.
Their case, first
The government’s inquiry, led by Justice Marie-Josée Hogue, is careful about the intelligence, and so are we.
The inquiry and the government
- The inquiry: “much of the intelligence is uncorroborated and of unknown or uncertain reliability.” “It should not be taken as proven fact.” Hogue vol. 1, p. 30
- “Mr. Dong denies any involvement in these matters.” Hogue vol. 1, p. 30 Busing is ordinary, Hogue heard: “Apparently, it is common for a campaign to bus voters to a nomination contest.” His campaign “rented two buses to transport party members to the vote”; he did not know who arranged the bus with the foreign students, and testified “his campaign was not involved.” Hogue vol. 2, p. 105
The inquiry’s findings · Final Report, 28 January 2025
- The intelligence
- Uncorroborated; not proven fact
- Bad faith
- No evidence anyone acted in it
- Shortcomings
- Appear systemic
- On the people who handled it: “I have no evidence to suggest that anyone acted in bad faith. The shortcomings observed appear to have been systemic ones, the consequences of which were exacerbated by various external factors.” Hogue vol. 1, p. 108
- On the flow of information in the 2019 and 2021 election periods: “With the exception of one report that was not passed on to the SITE TF in a timely fashion, the way in which information flowed was satisfactory.” And since: “Fortunately, the intelligence delivery system has since been completely redesigned.” “I have not been able to put this new system to the test to see how effective and resilient it is, but the evidence suggests that it is much more suitable than the previous one.” Hogue vol. 1, p. 108
The inquiry’s findings · the system and the result
- Information flow, 2019 and 2021
- Satisfactory, one report excepted
- Delivery system
- Redesigned since; not yet tested; “the evidence suggests that it is much more suitable than the previous one”
- The government
- Would have formed either way
- On NSICOP’s report, which this page also cites: “These assertions had the (perhaps unintended) effect of causing widespread public consternation, casting a cloud of suspicion over all parliamentarians and contributing to the erosion of Canadians’ trust in their democratic institutions.” Hogue vol. 1, p. 102
- On the result: “I am confident that the Liberal Party would have formed the government with or without foreign interference in 2019 and 2021.” Hogue vol. 1, p. 37
- The government, the day the report landed: it “welcomes the Final Report’s findings, which reaffirmed that the 2019 and 2021 federal elections were free and fair.” Government statement
Justin Trudeau’s case, as Liberal leader, in his own testimony as Hogue records it
Trudeau’s questions to Broadhurst · September 2019
- PRC behind the buses?
- No clear answers
- Dong witting?
- No clear answers
- Result affected?
- No conclusions to share
- Action recommended?
- None
- Irregularities seen?
- No red flags
- Runner-up disputing?
- No
- He asked Broadhurst how certain CSIS was that the PRC was behind the buses, whether CSIS knew if Dong “was witting and aware of this,” whether the result could have been affected, whether CSIS recommended any action, whether party officials saw irregularities, and whether the losing contestant disputed the result. CSIS had “no conclusions to share at that point” and recommended nothing; there were “no red flags”; the runner-up was not disputing it Hogue vol. 2, p. 108
- He “agreed that there should be a fairly high threshold for overturning the results of a nomination contest” and “did not feel there was sufficient or sufficiently credible information to justify removing Mr. Dong” Hogue vol. 2, p. 108
- He “was faced with a binary choice: remove Mr. Dong or leave him in place” Hogue vol. 2, p. 109
The choice, as the leader testified it · September 2019
- Option 1
- Remove Mr. Dong
- Option 2
- Leave him in place
- Chosen
- Option 2
- “Certainly in the case that candidate got elected, there would be questions we would have to follow up on after the election to properly understand what happened” Hogue vol. 2, p. 109
- Asked whether it was revisited, he “confirmed that the Liberal Party investigated immediately after they received the information” in September; for him, “the follow-up was about obtaining more clarity from intelligence agencies” Hogue vol. 2, p. 109
That is a real case. Intelligence is not evidence, and Broadhurst could not tell the party officials he questioned what he was asking about Hogue vol. 2, p. 107. Hold that thought, and watch what each office did with the warning.
The receipts
The people who could tell the public.
Panel of Five · Don Valley North · September 2019
- Members
- 5 senior public servants
- Asked for
- More reporting from the agencies
- Public warning
- Threshold not met
- The Panel of Five weighs it, and does not tell you. The Panel is made up of 5 senior public servants (the Clerk of the Privy Council, the National Security and Intelligence Advisor, and the deputy ministers of Justice, Public Safety and Foreign Affairs) who may warn Canadians if an election is threatened Hogue vol. 1, p. 30. Among its 2019 members, in Hogue’s words: “Ms. Drouin, a member of the 2019 Panel,” Hogue vol. 2, p. 115 and “at least two of the Panel members, Ms. Drouin (Justice) and Monik Beauregard (Public Safety).” Hogue vol. 2, p. 116 That is “Nathalie Drouin, then Deputy Minister of Justice.” Hogue vol. 2, p. 113 The NSIA in 2019 was Greta Bossenmaier Hogue vol. 2, p. 115.Some members “queried whether the nomination process was more a matter for the affected political party. However, the Panel decided to consider this intelligence, nonetheless.” It asked “intelligence agencies to continue to provide it with information regarding this matter” Hogue vol. 2, p. 106. Hogue gives no date for when CSIS first told the Panel, only that it was during the election period Hogue vol. 2, p. 106; Hogue records the order: “The Panel indicated that the Liberal Party should be told,” and CSIS then briefed the party Hogue vol. 1, p. 30.
Panel of Five · the seats in 2019
- Clerk of the Privy Council
- Not named on this page.
- Security and Intelligence Advisor
- Greta Bossenmaier
- Deputy Minister, Justice
- Nathalie Drouin
- Deputy Minister, Public Safety
- Monik Beauregard
- Deputy Minister, Foreign Affairs
- Not named on this page.
Hogue vol. 1, p. 30; vol. 2, pp. 113, 115, 116 - It “concluded that the threshold to make an announcement was not met” Hogue vol. 2, p. 106. Its reasons: the intelligence was “evolving and not firmly substantiated”; it concerned a nomination and “did not directly impact the electoral process”; and “If the candidate were elected, the party leader would be aware of the risk” Hogue vol. 2, p. 106
No public warning · the Panel’s reasons
- The intelligence
- Evolving; not firmly substantiated
- The contest
- A nomination, not the electoral process directly
- If elected
- The party leader would be aware
- The elections watchdog can’t act either. The Panel counted on the Commissioner of Canada Elections and the party being told Hogue vol. 2, p. 106. The Chief Electoral Officer “determined that no action could be taken at that time by his office” Hogue vol. 2, p. 110. And no law made it an offence: “Canada does not criminalize interfering in nominations” NSICOP p. 30
The pattern: the people who could have told the public relied on the watchdog and the party being told, and the watchdog could not act.
The party checks. The leader decides.
- The party is told, and checks what it can. On 28 September 2019 CSIS briefed the Liberal Party’s security-cleared representatives Hogue vol. 2, p. 106. One was Azam Ishmael, the national director Hogue vol. 2, p. 107. The party’s representative passed it to Jeremy Broadhurst, national campaign director Hogue vol. 2, p. 106, who called senior Privy Council Office officials “to see if there was additional information they could share,” but “did not ask for any specific additional information to be gathered at that point,” because he believed directing public servants would be inappropriate Hogue vol. 2, p. 107. Party officials told him “nothing stood out as abnormal” Hogue vol. 2, p. 107
The party’s check · September 2019
- Briefed
- 28 Sep 2019, cleared representatives
- Asked the PCO
- For more; nothing specific to gather
- Party officials
- Nothing abnormal
- Party rules, per Hogue
- Not particularly stringent
- Ishmael, in Hogue’s summary of his testimony, said it would be difficult for foreign states to interfere in the party’s nominations because the party has many security measures Hogue vol. 2, p. 107. Hogue’s finding on those measures: “not particularly stringent nor are their verification measures” Hogue vol. 2, p. 111
- The leader is told, and keeps the candidate. Broadhurst briefed Trudeau, as party leader, at the Ottawa airport Hogue vol. 2, p. 107. He “recommended to Mr. Trudeau that no immediate action be taken” Hogue vol. 2, p. 108. His account of why the officials gave no advice: “it’s not the place of intelligence officials to make that kind of recommendation” Hogue vol. 2, p. 108. Trudeau kept Dong on the ballot. His stated reasons: “a fairly high threshold for overturning the results of a nomination contest,” and not “sufficient or sufficiently credible information to justify removing Mr. Dong” Hogue vol. 2, p. 108
The leader’s decision · September 2019
- Broadhurst advised
- No immediate action
- Officials advised
- Nothing, by Broadhurst’s account
- Threshold to remove
- Fairly high, in Trudeau’s view
- The consequences he noted, in Hogue’s summary of his in camera testimony, whole: “Mr. Trudeau noted that not approving Mr. Dong’s endorsement would have had direct electoral consequences as the Liberal Party expected to win DVN. It would also have had a devastating impact on Mr. Dong personally.” Hogue vol. 2, p. 108
The pattern: the Panel relied on the party being told. The intelligence officials, Broadhurst said, “did not recommend that the Liberal Party should do anything in response,” and in his account advice was not their place. The party’s representatives told Broadhurst; Broadhurst asked the Privy Council Office for more and told the leader; and the leader, the only one with power over the candidacy, kept the candidate.
The paper trail.
Briefing to the PMO · after the 2019 election
- Requested by
- Prime Minister’s Office
- Given by
- Senior officials
- Record
- None found.
- After the vote, a briefing with no record found. Hogue: “the Commission received evidence that, after the 2019 election, the Prime Minister’s Office (“PMO”) requested, and received, a briefing about the reported irregularities from senior officials. It appears that no documentation exists on this.” Hogue vol. 2, p. 109 “Since then, the Prime Minister and the PMO have received additional briefings about Mr. Dong,” Hogue vol. 2, p. 109 and NSICOP cites the CSIS Director’s “Notes for DIR PM Brief: Don Valley North in the 2019 Election,” dated 8 February 2020 NSICOP p. 31, fn 213. The gap is that one post-election briefing. The Liberal Party “allowed Mr. Dong to run in both the 2019 and 2021 federal elections” NSICOP p. 31
- The CSIS brief that was recalled. CSIS wrote a National Security Brief dated 1 October 2019, “Foreign Interference in the 2019 Federal Campaign of Dong Han” Hogue vol. 2, p. 110. It “was recalled by the then CSIS Director shortly after a discussion with the National Security and Intelligence Advisor” Hogue vol. 2, p. 111. Hogue: “Recalling a document involves asking recipients to destroy it.” “While the underlying information and reports remain available to CSIS,” the brief “is no longer accessible” Hogue vol. 2, p. 111
CSIS National Security Brief · 1 October 2019
- Subject
- Don Valley North, 2019
- Status
- No longer accessible
- Reason given
- None.
- Their side: Cherie Henderson, in 2019 Director General of CSIS’s Intelligence Assessment Branch Hogue vol. 2, p. 117, told Hogue a recall “is not unusual, but (…) not regular, sort of in between.” Hogue vol. 2, p. 111, fn 51 Former Director David Vigneault “did not recall why this report was recalled”; he said a report might be recalled if, for instance, “it includes incorrect information or the report inadvertently identifies a source,” and “insisted he had never recalled a report because it was too sensitive or for political reasons.” Then-advisor Greta Bossenmaier “said she likely read the report and may have asked questions about it but did not remember asking for it to be recalled” Hogue vol. 2, p. 111. Hogue: “In the absence of any explanation for the recall, I cannot draw any conclusion from this incident, other than noting that this report was recalled” Hogue vol. 2, p. 111
Why the brief was recalled · the accounts
- Henderson, CSIS
- Not unusual, not regular
- Vigneault, Director
- Did not recall why
- Bossenmaier, NSIA
- Did not remember asking for it
- Hogue
- No explanation; no conclusion drawn
- It is not the only paper on the case: the reports cite a SITE Task Force document, “FI efforts against Dong Han” Hogue vol. 2, p. 105, fn 48, and the Director’s notes of February 2020 NSICOP p. 31, fn 213. The recalled brief is the one dated during the campaign, 1 October 2019.
The pattern: a CSIS brief on this case, dated 1 October 2019, was recalled shortly after a discussion. The Director “did not recall why,” and Hogue had no “explanation for the recall.”
The system around it
These findings cover the whole period, not this riding.
No record of who read what.
CSIS and Public Safety · specific intelligence products
- Who received it
- No tracking system.
- Who read it
- No tracking system.
- The inquiry, across both elections: “Information that should have reached ministers and even the Prime Minister did not. I was unable to ascertain from the evidence exactly why this happened in each case.” Hogue vol. 1, p. 108 “There was no way of knowing who had received a particular report, whether those who had received it had read it and whether any action had been taken as a result” Hogue vol. 1, p. 108
- The national security review agency: CSIS and Public Safety “did not have a system for tracking who received and read specific intelligence products, creating unacceptable gaps in accountability” NSIRA F.7. On the Panel: its “high threshold for a public announcement is unlikely to be triggered by traditional foreign interference, which typically targets specific ridings” NSIRA F.5
- A separate dispute, in 2021: NSIRA found “disagreement between senior public servants and the NSIA as to whether intelligence assessments should be shared with the political executive,” and “the NSIA’s interventions resulted in two products not reaching the political executive, including the Prime Minister” NSIRA F.9. The NSIA’s side, as PCO gave it: the activity in one report “did not qualify as foreign interference, but was rather part of regular diplomatic practice” NSIRA. That concerns 2 2021 analytical reports on PRC interference, not the 2019 recall.
- NSICOP wrote that a PRC network in a place its public report redacts “had some contact with at least 11 candidates and 13 campaign staffers, some of whom appeared to be wittingly working for the PRC” NSICOP p. 26. “Wittingly” is NSICOP’s word. Hogue’s response: some NSICOP findings on “witting” participation “were more definitive than the underlying intelligence could support,” and “I did not see evidence of “traitors” in Parliament” Hogue vol. 1, p. 103. The public text names no candidate. Neither do we.
The pattern, in the review agency’s words: the Panel’s “high threshold for a public announcement is unlikely to be triggered by traditional foreign interference, which typically targets specific ridings.” NSIRA F.5 On our reading, a nomination in one riding is that kind of target. And CSIS and Public Safety had no system to track who received and read their intelligence products NSIRA F.7.
Where the two reports disagree
When did the leader hear? Hogue: Broadhurst briefed Trudeau “at the airport in Ottawa on September 30, two days after CSIS briefed the Liberal Party” Hogue vol. 2, p. 107. NSICOP: the party’s representatives “briefed the PM alone the following day,” that is, 29 September NSICOP p. 31. NSICOP’s account of its own discussion with the Prime Minister is redacted NSICOP p. 31. We give both. Either way, he knew 3 weeks before the 21 October vote.
The answer to their case
Every line of their case can be true, and none of it touches the receipts.
“No evidence of bad faith.” Agreed: the page alleges none. The question is not what anyone intended. It is what they did. And the record shows a Panel that relied on the party being told, a campaign director who checked what he could and “did not ask for any specific additional information to be gathered at that point,” a leader who weighed the seat and the candidate’s career, a briefing for which “It appears that no documentation exists,” and a brief recalled with no explanation given to the inquiry Hogue vol. 2, pp. 107, 109, 111.
“A high threshold for overturning a nomination.” The choice was never only remove or keep. The Panel asked agencies to keep reporting Hogue vol. 2, p. 106. Broadhurst asked officials what more they could share, but did not ask, at that point, for anything specific to be gathered Hogue vol. 2, p. 107. Trudeau told the inquiry he “has had to eject candidates and members of Parliament (MPs) from the Liberal Party in the past, for a variety of reasons” Hogue vol. 2, p. 108. Our read: the threshold was his to set, and he set it beside “direct electoral consequences” Hogue vol. 2, p. 108.
The options on the record · 2019
- Remove the candidate
- Not done
- Keep the candidate
- Done
- Keep the agencies reporting
- The Panel asked for it
- Ask for specific information to be gathered
- Not asked, at that point
- Eject: a power he testified he has used before
- Not used here
“The elections were free and fair.” The inquiry said the government would have formed either way Hogue vol. 1, p. 37. It also said: “It is possible that results in a small number of ridings were affected, but this cannot be said with certainty.” Hogue vol. 1, p. 37 “Free and fair” is the government’s summary of a report that says that. A riding is not a rounding error to the people who live in it.
“Uncorroborated intelligence.” Yes. That is why this page makes no claim about the candidate. Uncorroborated is also why someone should have run it down: asked, recorded, followed up. Trudeau said there would be questions to follow up on after the election; asked whether it was revisited, he pointed to the party’s September check. Hogue: “He did not provide further information in response to my question at that time.” Hogue vol. 2, p. 109 The record shows the CSIS brief recalled and, for the post-election briefing, it appears, no documentation. The way to settle intelligence is to keep the paper.
Running it down · September 2019 to after the vote
- Asked
- What more officials could share; nothing specific to be gathered
- Recorded
- CSIS brief recalled; no documentation of the PMO briefing
- Followed up
- After the election, he said; nothing further given to the inquiry
Our read
This is our judgement on the documented facts above, not a finding of the inquiry.
A pragmatic person reading Hogue’s own pages would conclude this: in 2019, the warning went from the Panel to the party, from the party’s representatives to Broadhurst, and from Broadhurst to the leader, the only one with power over the candidacy, who kept the candidate. The Panel relied on the party and the watchdog being told. The watchdog could not act, and the Chief Electoral Officer “determined that no action could be taken at that time by his office.” The intelligence officials, Broadhurst said, “did not recommend that the Liberal Party should do anything in response,” and in his account advice was not their place. The party leader weighed a riding the party expected to win, and the candidate’s career, against intelligence the inquiry calls “uncorroborated and of unknown or uncertain reliability,” and kept the candidate.
What the record holds · after the vote
- PMO briefing after the vote
- No documentation found.
- CSIS brief, 1 Oct 2019
- Recalled; no longer accessible
- Reason for the recall
- None given to the inquiry.
Of the briefing his office received after the vote: “It appears that no documentation exists.” The CSIS brief on the case “is no longer accessible,” though “the underlying information and reports remain available to CSIS”; it was recalled after a discussion, the Director “did not recall why,” and Hogue had no “explanation for the recall.” Hogue had no evidence that anyone acted in bad faith, and wrote that the shortcomings “appear to have been systemic ones.” A system in which a warning can pass from office to office and leave, it appears, no record of the briefing after the vote is one a foreign state can work through. The decisions in it were made by people with names, and they are on this page.
The students on those buses were told, by the reporting, that their visas depended on a vote. The inquiry found no documentation of what the Prime Minister’s Office was told about it after the election, and no witness explained why the CSIS brief of 1 October 2019 was recalled.
- CSIS ↓Warns the Panel, the watchdog and the party
- Panel of Five ↓Relies on the party being told; no announcement
- Elections watchdog ↓No action could be taken
- Liberal Party ↓Checks what it can; nothing abnormal
- The leader ↓Keeps the candidate
- After the voteA briefing; no record found
Still open
The reports could not determine:
- What happened at the 12 September 2019 meeting. Hogue: “It is not the mandate of this Commission to determine what actually took place” and “I would not be able to do so on the record before me” Hogue vol. 2, p. 111. The Panel had “no reliable information about whether the students actually voted” Hogue vol. 2, p. 106.
- Who arranged and paid for the bus carrying the students (Dong “did not know” Hogue vol. 2, p. 105).
- Why the 1 October 2019 CSIS brief was recalled Hogue vol. 2, p. 111.
- What the Prime Minister’s Office was told after the election, and by whom Hogue vol. 2, p. 109.
- Why intelligence that should have reached ministers and the Prime Minister did not Hogue vol. 1, p. 108.
- What further intelligence exists. Hogue: “Should additional intelligence respecting or implicating the 2019 DVN Liberal Party nomination process exist, I could not disclose it” Hogue vol. 2, p. 109.
