Breaking: CSIS warned Health Canada of “insider threat” from Wuhan Institute-tied scientist Dr. Qiu Seven Months Before Lethal Ebola Shipped to China


Sam Cooper
In an explosive admission, Parliament’s Canada-China Committee has confirmed that Canada’s spy agency, CSIS, issued a direct and unheeded warning to senior health officials in August 2018, raising concerns about “insider threat activities” linked to Dr. Xiangguo Qiu and her husband, Keding Cheng.
This alert, delivered seven months before the couple’s network—with connections to the highest levels of Chinese biological weapons research—coordinated the shipment of live Ebola and Henipah virus samples from Canada’s high-security National Microbiology Laboratory (NML) to the Wuhan Institute of Virology (WIV), highlighted risks posed by their continued access to sensitive materials.
“CSIS held a briefing for personnel responsible for security at [Public Health Canada],” in August 2018 that “focused on foreign interference and included possible indicators of insider threat activities, as well as other security risks,” according to CSIS’s submission to the Committee. In CSIS’s presentation, “student programs were identified as being one of these possible threat vectors,” prompting “[Public Health Canada] to flag two scientists to CSIS, Dr. Cheng and Dr. Qiu,” the Committee report, released Tuesday, states.
Despite these explicit warnings, no immediate restrictions were placed on Qiu, Cheng, or their Chinese students’ access to Canada’s sensitive research materials. In December 2018, Public Health Canada authorized a fact-finding investigation into the concerns, but the delayed response effectively allowed them to continue their operations, further endangering Canada’s security.

The Committee report also finds—like the ongoing Hogue Commission—that Justin Trudeau’s government, including senior bureaucrats and ministers, showed a reluctance to act on or even acknowledge urgent alerts from CSIS, exposing a stark divide between CSIS’s view of Chinese threats and Trudeau’s.
Dr. Qiu’s associations with China’s military and scientific programs had deep roots. She began her work at the Winnipeg NML in 2003, followed by her husband’s employment there in 2006.
As early as 2013, Keding Cheng filled out an application for the PRC’s “Science and Technology Innovation Talent Program of Henan Province,” requiring applicants to “passionately love the socialist motherland [PRC]” and maintain Chinese citizenship.
By 2016, Dr. Qiu was nominated for an award by a senior military official from the Chinese Academy of Military Medical Sciences, recognizing her collaborations with Major-General Chen Wei, a leading figure in China’s biological weapons research. CSIS investigations revealed that Dr. Qiu and Major-General Chen collaborated on multiple research projects dating back to 2012.
Dr. Qiu’s use of Canada’s facilities to benefit China was well recognized in Beijing. An award nomination for Dr. Qiu noted that she “used Canada’s Level 4 Biosecurity Laboratory as a base to assist China to improve its capability to fight highly pathogenic pathogens … and achieved brilliant results.”
In October 2016, Dr. Qiu co-authored a paper with Major-General Chen and other scientists affiliated with the Chinese Academy of Military Medical Sciences, further deepening her connection to Chinese military research. By this time, Qiu had also been recruited into China’s Thousand Talents Program—a PRC initiative aimed at harnessing international scientific expertise—and these affiliations, conspicuously absent from her Canadian curriculum vitae, made her a person of interest to CSIS, especially as her work increasingly intersected with China’s biosecurity research.
Concerns over Qiu and Cheng’s activities continued to mount at the NML. In October 2018, Cheng, accompanied by a restricted visitor, attempted to exit the lab with two Styrofoam containers, claiming they were empty. By January 2019, Cheng breached security again by using another employee’s passcode to enter the NML.
On March 23, 2019, Public Health Canada received its fact-finding report, which advised administrative investigations into Qiu and Cheng. Yet, only days later, on March 31, live samples of Ebola and Henipah viruses were shipped from the NML to the WIV, highlighting critical lapses in Canada’s security protocols.
In response to these revelations, the Committee’s report outlines recommendations to safeguard Canada’s scientific resources from similar threats in the future. Chief among these is a call for the Government of Canada to immediately terminate all research collaboration with PRC-affiliated entities in sensitive fields, such as artificial intelligence, aerospace, and advanced digital infrastructure.
A key recommendation is to designate the Wuhan Institute of Virology and the Thousand Talents Program as Named Research Organizations under Public Safety Canada, subjecting them to enhanced scrutiny and restricted partnerships due to their potential security risks. Furthermore, the Committee suggests that Canada explore constitutionally compliant legal measures to prevent individuals under national security investigation from leaving the country. Despite RCMP investigations, the couple was able to leave Canada.
As investigations mounted, irregularities in the WIV shipment were noticed, and it was only in January 2021 that Public Health Canada terminated the couple’s employment. Nathalie Drouin, Deputy Clerk of the Privy Council, acknowledged with evident understatement, “it is a timeline that needs to be looked at.” However, Richard Fadden, the director of CSIS from 2009 to 2013, testified that the timeline “was too long” and the viral shipment to WIV “should not have happened.”
In his opinion, the incident at the Winnipeg NML revealed a deep cultural issue long present in Canada’s federal administration. “I don’t think the culture in this particular lab and in large parts of the public service had caught up with the change in facts as we understand China,” Fadden said. His comments emphasize a notable gap between CSIS’s understanding of the Chinese threat and that of Trudeau’s administration.
“This gap in the understanding of risk between national security and science sectors at the federal level, particularly with regard to the threat to Canadian interests posed by actions of the Chinese Communist Party (CCP), was illustrated in testimony before the Special Committee,” the report says.
On one hand, Minister of Health Mark Holland noted that “countries such as China are implicating themselves in our domestic processes in a way that would have been unimaginable just five years ago” and are “potentially willing, in this instance, to use pathogens that threaten humanity in order to advance their geopolitical agenda.” But Fadden pointed out that “CSIS was already aware of concerns about the PRC’s actions,” noting that since Xi Jinping’s rise to power in 2013, the institutionalization of espionage and interference techniques by the CCP has intensified.
Adding to these concerns is the Trudeau government’s controversial denial of access to related records, noted by the report, raising questions of transparency and whether there may have been a cover-up of key details surrounding the case.

2025 Federal Election
CHINESE ELECTION THREAT WARNING: Conservative Candidate Joe Tay Paused Public Campaign

Sam Cooper
Now, with six days until Canada’s pivotal vote—in an election likely to be decided across key Toronto battleground ridings—it appears that Tay’s ability to reach voters in person has also been downgraded.
Joseph Tay, the Conservative candidate identified by federal authorities as the target of aggressive Chinese election interference operations, paused in-person campaigning yesterday following advice from federal police, The Bureau has learned.
Two sources with awareness of the matter said the move came after the SITE Task Force—Canada’s election-threat monitor—confirmed that Tay is the subject of a highly coordinated transnational repression operation tied to the People’s Republic of China. The campaign seeks not only to discredit Tay, but to suppress the ability of Chinese Canadian voters to access his campaign messages online, via cyber operations conducted by Beijing’s internet authorities.
Now, with six days until Canada’s pivotal vote—in an election likely to be decided across key Toronto battleground ridings—it appears that Tay’s ability to reach voters in person has also been downgraded.
Tay, a journalist and pro-democracy advocate born in Hong Kong, is running for the Conservative Party in the Don Valley North riding. Federal intelligence sources have confirmed that his political activities have made him a top target for Beijing-linked online attacks and digital suppression efforts in the lead-up to next week’s federal election.
Tay’s need to suspend door-knocking yesterday in Don Valley North echoes concerns raised in a neighbouring riding during the 2021 federal campaign—where The Bureau previously uncovered allegations of Chinese government intimidation and targeting of voters and a Conservative incumbent. According to senior Conservative sources, Chinese agents attempted to intimidate voters and monitor the door-to-door campaign of then-incumbent MP Bob Saroya in Markham–Unionville.
Paul Chiang, a former police officer who unseated Saroya in 2021, stepped down as a candidate earlier this month after the RCMP confirmed it was reviewing remarks he made to Chinese-language media in January. During that event, Chiang reportedly said the election of Tay—a Canadian citizen wanted under Hong Kong’s National Security Law—to Parliament would cause “great controversy” for Canada. He then suggested, in a remark reported by a Chinese-language newspaper, that Tay could be turned over to the Toronto Chinese Consulate to claim the $180,000 bounty on his head. Chiang apologized after the comments were reported, claiming his remarks had been made in jest.
In a briefing yesterday, SITE disclosed that Tay has been the victim of similarly threatening online messaging.
One Facebook post circulated widely in Chinese-language forums declared: “Wanted for national security reasons, Joe Tay looks to run for a seat in the Canadian Parliament; a successful bid would be a disaster. Is Canada about to become a fugitive’s paradise?”
Tay, a former Hong Kong broadcaster whose independent reporting from Canada has drawn retaliation from Beijing, rejected Chiang’s apology in March, calling the remarks “the tradecraft of the Chinese Communist Party.” He added: “They are not just aimed at me; they are intended to send a chilling signal to the entire community to force compliance with Beijing’s political goals.” His concerns were echoed by NGOs and human rights organizations, which condemned Chiang’s comments as an endorsement of transnational repression.
In light of the RCMP’s reported advice to Tay this week, the challenges faced by Conservative candidates attempting to meet Chinese Canadian voters in Greater Toronto appear to reflect a broader and troubling pattern.
According to multiple senior figures from Erin O’Toole’s 2021 Conservative campaign—who spoke on condition of anonymity—O’Toole’s team was briefed by Canadian intelligence officials that Chinese government actors were surveilling then-incumbent MP Bob Saroya during the campaign. One source recalled, “There were Chinese officials following Bob Saroya around,” adding that “CSIS literally said repeatedly that this was ‘coordinated and alarming.’”
When asked to comment, O’Toole—who stepped down as leader following the Conservative’s 2021 loss—acknowledged awareness of voter intimidation reports but declined to confirm whether CSIS had briefed his team directly on the matter.
“Our candidate Bob Saroya was a hardworking MP who won against the Liberal wave in 2015,” O’Toole wrote in a statement. “He won in 2019 as well, but thousands of votes from the Chinese Canadian community stayed home in 2021. We heard reports of intimidation of voters. We also know the Consul General from China took particular interest in the riding and made strange comments to Mr. Saroya ahead of the election. It was always in the top three of the eight or nine ridings that I believe were flipped due to foreign interference.”
SITE’s new findings on Tay’s campaign in Don Valley North reinforce those long-standing concerns. “This is not about a single post going viral,” SITE warned. “It is a series of deliberate and persistent activity across multiple platforms—a coordinated attempt to distort visibility, suppress legitimate discourse, and shape the information environment for Chinese-speaking voters in Canada.”
The Task Force said the most recent wave of coordinated online activity occurred in late March, when a Facebook post appeared denigrating Tay’s candidacy. “Posts like this one appeared en masse on March 24 and 25 and appear to be timed for the Conservative Party’s announcement that Tay would run in Don Valley North,” SITE stated in briefing materials.

Ottawa Confirms China interfering with 2025 federal election: Beijing Seeks to Block Joe Tay’s Election

Sam Cooper
The announcement marks the first time SITE has publicly confirmed that China is directly seeking to block the election of a particular candidate during the 2025 federal election—an election already shadowed by growing concern over Chinese interference through cyber operations and diaspora political networks.
One week before Canadians head to the polls, Ottawa has confirmed an escalation in China’s election interference efforts, identifying Conservative candidate Joseph Tay as the target of a widespread and highly coordinated ongoing transnational repression campaign tied to the People’s Republic of China.
The SITE Task Force—Canada’s agency monitoring information threats during the election—formally disclosed today that Tay, the Conservative Party candidate for Don Valley North, is the victim of inauthentic online amplification, digital suppression, and reputational targeting orchestrated by networks aligned with Beijing’s foreign influence operations.
The announcement marks the first time SITE has publicly confirmed that China is directly seeking to block the election of a particular candidate during the 2025 federal election—an election already shadowed by growing concern over Chinese interference through cyber operations and diaspora political networks.
“This is not about a single post going viral,” SITE warned. “It is a series of deliberate and persistent activity across multiple platforms—a coordinated attempt to distort visibility, suppress legitimate discourse, and shape the information environment for Chinese-speaking voters in Canada.”
SITE said the most recent coordinated activity occurred in late March, when a Facebook post appeared denigrating Tay’s candidacy. “Posts like this one appeared en masse on March 24 and 25 and appear to be timed for the Conservative Party’s announcement that Tay would run in Don Valley North,” SITE stated in briefing materials.
One post, circulated widely in Chinese-language spaces, featured an image that read: “Wanted for national security reasons, Joe Tay looks to run for a seat in the Canadian Parliament; a successful bid would be a disaster. Is Canada about to become a fugitive’s paradise?”
Significantly, according to The Bureau’s analysis, the post’s message resembles earlier remarks made by then-Liberal MP Paul Chiang to a small group of Chinese journalists in Toronto in January—comments made shortly after Tay’s inclusion on a Hong Kong bounty list was first publicized.
Chiang reportedly told the journalists that Tay’s election would raise significant concern due to the bounty he faced, before suggesting that Tay could be turned over to the Chinese consulate in Toronto.
Tay, a Hong Kong-born human rights advocate, was named in December 2024 by Hong Kong authorities as one of six overseas dissidents subject to an international arrest warrant and monetary bounty. His photograph appeared on a wanted list offering cash rewards for information leading to his capture—an unprecedented move that Canadian officials condemned as a threat to national sovereignty.
“The decision by Hong Kong to issue international bounties and cancel the passports of democracy activists and former Hong Kong lawmakers is deplorable,” SITE stated today. “This attempt by Hong Kong authorities to conduct transnational repression abroad—including by issuing threats, intimidation or coercion against Canadians or those in Canada—will not be tolerated.”
However, while facing an international wave of criticism, Prime Minister Mark Carney did tolerate his candidate’s alleged role in this activity. When asked earlier in the campaign whether he stood by Chiang, Carney said the Liberal MP retained his confidence. Chiang ultimately stepped down only after the RCMP confirmed it was reviewing the matter.
Chiang, who had been endorsed by Prime Minister Carney, was replaced as the Liberal candidate by Peter Yuen, the former Deputy Chief of the Toronto Police Service.
As The Bureau previously reported, Yuen traveled to Beijing in 2015 with a delegation of Ontario Chinese community leaders and politicians to attend a major military parade hosted by President Xi Jinping and the People’s Liberation Army—an event commemorating the Chinese Communist Party’s Second World War victory over Japan.
Yuen’s presence at that event—and his subsequent appearances at diaspora galas alongside leaders from the Confederation of Toronto Chinese Canadian Organizations (CTCCO), a group cited in national security reporting—has drawn media scrutiny.
Both Chiang and Yuen have stated that they strongly support Canada’s rule of law and deny any involvement in inappropriate activities.
According to SITE’s findings, Tay’s campaign has been the focus of two parallel strands of foreign influence since the beginning of the writ period. The first involves inauthentic and coordinated amplification of content related to Tay’s Hong Kong arrest warrant, including repeated efforts to cast doubt on his fitness for office. This activity has spanned multiple platforms commonly used by Chinese-speaking Canadians, including WeChat, Facebook, TikTok, RedNote, and Douyin.
The second strand is a deliberate suppression of Tay’s name in both simplified and traditional Chinese on platforms based in the People’s Republic of China. When users attempt to search for Tay, the platforms return only information related to the Hong Kong bounty—effectively erasing his campaign content and political biography from the digital public square.
While SITE noted that engagement levels with the disinformation remained limited, the timing, repetition, and cross-platform consistency led the Task Force to conclude this is a serious case of foreign interference.
