The inquiry heard earlier this month from NDP member of Parliament Jenny Kwan, herself a target of foreign interference by China. She said she doesn't know how effective the government's TikTok ban can be, since it does not extend to personal devices.
"In her opinion, by engaging with the platform, Canadian politicians are providing TikTok with relevant data points and legitimizing a 'brainwashing machine' used to push PRC [People's Republic of China] narratives on a variety of subjects," Kwan's inquiry witness statement says.
Top secret CSIS note details major concerns with TikTok
According to a top secret briefing note drafted by the Canadian Security Intelligence Service and made public through the inquiry, CSIS warned in December 2022 that TikTok could be exploited by the Chinese government to bolster its influence and power in Canada.
The app, which is owned by the Chinese-based company ByteDance, can gather sensitive user data, CSIS said in the briefing note.
"Despite assurances to the contrary, personal data on TikTok users is accessible to China," CSIS said.
The app collects a wide range of user information, including biometric data like facial geometry, iris scans, voice patterns and fingerprints. TikTok also gathers information from a person's phone, including GPS location, browsing history and technical specifics like the device's serial number, CSIS said.
"While ByteDance claims that all TikTok user data is stored in the United States and Singapore— not in China — ByteDance's servers are all located in China," CSIS wrote.
CSIS also said TikTok censored topics related to democratic values and failed to remove 90 per cent of disinformation ads about the 2022 U.S. midterm elections.
