Meng Wanzhou, who is Huawei's chief financial officer and deputy chair, was arrested in Vancouver on 1 December, Canada's Department of Justice said.
Ms Meng is being sought for extradition by the US, the department added.
Huawei said it had little information about the charges and was "not aware of any wrongdoing by Ms Meng".
Ms Meng, daughter of company founder Ren Zhengfei, was detained while transferring between flights, the firm said.
She will face a bail hearing on Friday, a spokesman for Canada's Department of Justice said.
