Electronic documents are governed by s.31.1 to 31.8 of the CEA. The provisions are meant to apply "in conjunction with either some common law general rule of admissibility of documents or some other statutory provision". The sections have the effect of deeming electronically produced documents as "best evidence" (see s.31.1 and 31.2).
In determining admissibility of electronic documents the court must determine whether the record is authentic and reliable.
These rules however are not intended to "not affect any rule of law relating to the admissibility of evidence, except the rules relating to authentication and best evidence."
These provisions are mean to address the fact that "technological change has rendered the former distinction between originals and copies a moot distraction in many areas".
It has been suggested that s. 31 is not designed as an exception to hearsay, instead only provide a process of authentication and admissibility.
In most cases where electronic documents are being tendered as documentary evidence--ie. where the data was inputted by a human--it should be treated as hearsay.
In order to admit electronic documents for the truth of its contents, in the absence of the author, may only be admitted as business records through s. 30 of the CEA or by using one of the hearsay exceptions.
The admission of electronic documents will vary on the format that the record takes (printout, scanned copy, or native digital format). All cases the documents must be authentic and satisfy the best evidence rule.

Receipt of Electronic Documents
Section 842 permits courts to "create, collect, receive, store, transfer, distribute, publish or otherwise deal with electronic documents" in accordance with the Code or rules of court.
Transfer of data
843. (1) Despite anything in this Act, a court may accept the transfer of data by electronic means if the transfer is made in accordance with the laws of the place where the transfer originates or the laws of the place where the data is received.
Time of filing
(2) If a document is required to be filed in a court and the filing is done by transfer of data by electronic means, the filing is complete when the transfer is accepted by the court.
2002, c. 13, s. 84.
Documents in writing
844. A requirement under this Act that a document be made in writing is satisfied by the making of the document in electronic form in accordance with an Act or the rules of court.
2002, c. 13, s. 84.
Definition of Electronic Documents
Under s. 31.8 of the CEA, "electronic documents" are defined as:
...data that is recorded or stored on any medium in or by a computer system or other similar device and that can be read or perceived by a person or a computer system or other similar device. It includes a display, printout or other output of that data.
This definition would include emails, all computer files, meta data associated with computer files, content of websites such as Facebook, Twitter, and chat logs found online.
Similarly, s. 841 of the Code defines an "electronic document" as "data that is recorded or stored on any medium in or by a computer system or other similar device and that can be read or perceived by a person or a computer system or other similar device. It includes a display, print-out or other output of the data and any document, record, order, exhibit, notice or form that contains the data."
While "data" is defined as "representations of information or concepts, in any form".
The burden is upon the party tendering the electronic document to prove its authenticity:
Authentication of electronic documents
31.1 Any person seeking to admit an electronic document as evidence has the burden of proving its authenticity by evidence capable of supporting a finding that the electronic document is that which it is purported to be.
2000, c. 5, s. 56.
There is some suggestion that the party seeking admission of the record has the burden to establish the absence of any tampering.
Authentication of cell phone evidence
In relation to the admission of text messages found on a cell phone, the question of who sent the text messages is an issue of authentication and relevance not hearsay. Where the party adducing the evidence cannot prove who sent the message then they are not reliable".
Proof of identity of the sender which is necessary for authentication and reliability should include elements such as:
- recorded purchaser and subscriber;
- usage being consistent with the activities of the alleged user;
- location where the phone was used
- observational evidence of "exclusive or non-exclusive use" of the cell phone;
- contents of the cell phone text messages and telephone calls;
- patterns in cellphone and text message communications including the messages themselves; and
- evidence from witnesses who received communcaitions from a cell phone and who can identify the source of those communications.

Best Evidence Rule
The "best evidence rule" can be satisfied by establishing either:
- "the integrity of the electronic documents system" that generated the document (s. 31.2(1)(a)) which is presumed (s. 31.3, see "presumption of integrity" below).
- in the case of printouts, that the "printout has been manifestly or consistently acted on, relied on or used as a record of the information recorded or stored in the printout" (s. 31.2(2))
- the presumption relating to electronic signatures (see s. 31.4)
Application of best evidence rule — electronic documents
31.2 (1) The best evidence rule in respect of an electronic document is satisfied
- (a) on proof of the integrity of the electronic documents system by or in which the electronic document was recorded or stored; or
- (b) if an evidentiary presumption established under section 31.4 applies.
(2) Despite subsection (1), in the absence of evidence to the contrary, an electronic document in the form of a printout satisfies the best evidence rule if the printout has been manifestly or consistently acted on, relied on or used as a record of the information recorded or stored in the printout.
2000, c. 5, s. 56.

Integrity of Electronic Document System
The authenticity and reliability of electronic documents can be established by "proof of the integrity of the electronic documents system rather than that of the specific electronic document".
Proof of integrity is established by factors including the manner of record, compliance with industry standards, business reliance, and security.
Presumption of Integrity
Under s. 31.3, in "absence of evidence to the contrary", the integrity of electronic documents are presumed where the is evidence of at least one of the following:
- "that at all material times the computer system or other similar device used by the electronic documents system was operating properly" (s. 31.3(a));
- if the device was not operating properly at all material times, that the malfunction "did not affect the integrity of the electronic document and there are no other reasonable grounds to doubt the integrity of the electronic documents system" (s. 31.3(a));
- that "the electronic document was recorded or stored by a party who is adverse in interest to the party seeking to introduce it";(s. 31.3(b)) or
- the document "was recorded or stored in the usual and ordinary course of business by a person who is not a party and who did not record or store it under the control of the party seeking to introduce it." (s. 31.3(c))
Presumption of integrity
31.3 For the purposes of subsection 31.2(1), in the absence of evidence to the contrary, the integrity of an electronic documents system by or in which an electronic document is recorded or stored is proven
- (a) by evidence capable of supporting a finding that at all material times the computer system or other similar device used by the electronic documents system was operating properly or, if it was not, the fact of its not operating properly did not affect the integrity of the electronic document and there are no other reasonable grounds to doubt the integrity of the electronic documents system;
- (b) if it is established that the electronic document was recorded or stored by a party who is adverse in interest to the party seeking to introduce it; or
- (c) if it is established that the electronic document was recorded or stored in the usual and ordinary course of business by a person who is not a party and who did not record or store it under the control of the party seeking to introduce it.
2000, c. 5, s. 56.
Standard of Proof
The presumption can be invoked where the party adducing the electronic evidence can prove on a standard of balance of probabilities that one of the categories in s. 31.3 applies.
See R v Avanes, 2015 ONCJ 606 (CanLII) at para 63
Admissibility of Contents of Records
Once a computer record is authenticated, the records will usually be admissible under one of the following methods of admissibility for the truth of their contents:
- CEA business records (s. 30),
- CEA financial records (s. 29),
- common law business documents,
- principled exception to hearsay, or
- real evidence
Where compilation was carried out by automated means, it may be possible to admit them through the common law business record method.
Evidence that is "automatically recorded by any means, other than by human labour, and the evidence so recorded can be reproduced in any form, intelligible to the human mind, the reproduction is admissible as real evidence." However, "The weight to be attached to such evidence will depend on the accuracy and integrity of the process employed."
Admission of Electronic Records under the Principled Approach
The analysis of reliability should "be assessed by focusing on the circumstances in which information was generated, recorded, stored, and reproduced.".

Proof by Standard, Procedure, Usage or Practice
Standards may be considered
31.5 For the purpose of determining under any rule of law whether an electronic document is admissible, evidence may be presented in respect of any standard, procedure, usage or practice concerning the manner in which electronic documents are to be recorded or stored, having regard to the type of business, enterprise or endeavour that used, recorded or stored the electronic document and the nature and purpose of the electronic document.
2000, c. 5, s. 56.
Proof by Affidavit
Proof by affidavit
31.6 (1) The matters referred to in subsection 31.2(2) [print-outs] and sections 31.3 [presumption of integrity] and 31.5 [proof by standard, procedure, usage or practice] and in regulations made under section 31.4 [proof of electronic signatures] may be established by affidavit.
(2) A party may cross-examine a deponent of an affidavit referred to in subsection (1) that has been introduced in evidence
- (a) as of right, if the deponent is an adverse party or is under the control of an adverse party; and
- (b) with leave of the court, in the case of any other deponent.
2000, c. 5, s. 56. [annotated]
Expert Evidence for Admissibility
Where the authenticity and admissibility is not being disputed there it should not be necessary to call any expert evidence in order to admit any digital evidence such as facebook, email or text messages. The trier of fact can assess weight of the evidence without expert evidence, and account for the possibility of fabrication, editing or deletion, based on the testimony of the parties involved in the communication.
It has been suggested that the admission of certain electronic evidence from "mundane" technology (such as social media websites or cell phone text messages) such that the typical user would be well versed in the functionality of the device and meaning of the contents, can be authenticated without expert evidence.
Proof of authenticity of the record and integrity of system can be proven either by expert evidence or by circumstantial evidence.  Expert evidence is preferred when authenticating the results from an extraction of an electronic device.
