How does the Canadian Embassy check the authenticity of the materials?

Applicants are advised not to provide false information. If the embassy finds false information, the consequences will be very serious, which will not only affect this visa application, but also have a great impact on future immigrants or children studying abroad. If the embassy has doubts about the materials, the applicant will encounter the process of administrative review, which means that the visa officer can't make a decision on whether to grant a visa on the spot, and the materials need to be handed over to the administrative review team for further investigation, and sometimes more materials need to be added to prove their authenticity.
