Prime Minister Justin Trudeau’s office in 2019 was told MP Han Dong (Don Valley North, Ont.) was under security surveillance but kept him in the Liberal caucus, records show. Trudeau’s chief of staff in 2023 had denied the subject was ever raised.

“It was alleged the People’s Republic of China interfered in the Don Valley North Liberal nomination of September 12, 2019,” said a top secret National Security Brief memo dated October 1, 2019. “The allegations are consistent with our current understanding of People’s Republic of China foreign interference activity in the Greater Toronto Area.”
