Canada’s Spy Agency Warned of Shock Waves From Huawei CFO Arrest

The Canadian Security Intelligence Service warned that the arrest of Huawei Technologies Co.’s chief financial officer in Vancouver on a U.S. extradition request would have global political ramifications, according to new documents that reveal the spy agency’s involvement in the case for the first time.

In a redacted Dec. 1, 2018 memo, CSIS said it was advised by the U.S. Federal Bureau of Investigation of plans to arrest Meng Wanzhou when she arrived on a flight to Vancouver later that day. The memo was among documents released late Thursday by the Federal Court in Ottawa after a request from Meng, who’s argued the extradition was politically motivated.
