An e-signature is a piece of data linked to communication that identifies the signer and affirms his or her agreement to the message's contents. The present study compares and contrasts the legal treatment of e-signatures in Iranian-Canadian law contracts. The research method is descriptive-analytical, and it is conducted with the use of library resources. An e-signature, according to Canadian legislation, is a signature that must be unique to the person who uses it and not to anybody else. The e-signature must be attached to the e-document in a way that allows the person to make that decision, and the technology or process by which the signature is made must be under the complete control of the person to whom the signature belongs, and that particular technology or process must be such that the person is known by it. The certification body is the organization that gives e-certifications to applicants under Canadian legislation. The applicant's public key, as well as the applicant's information and the certificate issuing center, are all included in these certificates. An e-signature, according to Iranian law, is any mark that is physically or conceptually linked to message data and is used to identify the signer of the "message data." Furthermore, an e-signature by itself does not confirm the signer's identity. As a result, the third party must ensure the message's legitimacy by identifying the digital signer.
