Canadian passport does not match China's previous status. In this case, it is necessary to issue a statement by the same person in Canada and apply for certification before it can be used in China.
The certification procedures declared by the same person in Canada are as follows:
Notarization by Canadian notary public
Canadian provincial government certification
Certification of China Embassy and Consulate in Canada
It takes 3- 15 working days to authenticate the same person's statement in Canada.
