Electronic Evidence In Canadian Courts
ELECTRONIC EVIDENCE IN CANADIAN COURTS
Electronic evidence refers to any information stored or transmitted in electronic form that is submitted in court to prove or disprove a fact. This includes emails, texts, social media posts, computer files, digital photos, electronic transaction records, metadata, and more.
1. Statutory Basis
Canadian law recognizes electronic evidence primarily through the Canada Evidence Act and the Criminal Code.
A. Canada Evidence Act
S. 31.1 – Admissibility of Electronic Documents:
A data message is considered a document and may be used as evidence if its integrity is proven.
S. 31.2 – Authentication:
The proponent must show that the data message has not been altered, and the source is reliable.
S. 31.3 – Business Records:
Electronic business records can be admissible if they are created in the usual course of business and maintained reliably.
B. Criminal Code
S. 487.014 & s. 487.017 – Digital Searches & Seizures:
Electronic devices can be seized and their contents admitted if warrant procedures are followed.
S. 9 & s. 10 – Authentication of Evidence:
Evidence from electronic sources must be authenticated before admission.
C. Other Relevant Rules
Rules of Evidence (Common Law):
Hearsay rules apply.
Relevance and reliability are key.
Chain of custody must be maintained.
2. Key Issues with Electronic Evidence
Authenticity / Integrity
The party introducing the evidence must prove it is what it purports to be.
Reliability
Courts assess whether the technology or method of storage is reliable.
Hearsay Concerns
Digital communications often involve statements made outside court, triggering hearsay analysis.
Chain of Custody
Demonstrating unbroken custody from creation to court submission is critical.
Privacy and Charter Issues
Evidence obtained through improper search or seizure may be excluded under s. 24(2) of the Charter.
3. Leading Case Law
A. Authenticity and Admissibility
R v. Cole, 2012 SCC 53
Issue: Employer access to employee’s computer.
Principle: Courts must consider privacy expectations when determining admissibility of electronic evidence.
Outcome: Evidence obtained in violation of privacy rights may be excluded.
R v. Spencer, 2014 SCC 43
Issue: Internet subscriber information obtained without proper authorization.
Principle: Section 8 Charter rights protect against unreasonable search/seizure of electronic data.
Outcome: Evidence obtained without proper authorization is inadmissible.
R v. Vu, 2013 SCC 60
Issue: Forensic search of digital devices.
Principle: Scope of digital searches must be reasonable and proportional; bulk seizure can violate Charter rights.
Outcome: Evidence beyond the scope of the warrant may be excluded.
B. Business and Electronic Records
R v. Finta, [1994] 1 S.C.R. 701
Principle: Business records, including electronic ones, are admissible if created in the ordinary course of business.
R v. Lifchus, [1997] 3 S.C.R. 320
Although primarily about jury instructions, this case highlights reliability standards applicable to evidence including electronic forms.
C. Social Media and Messaging Apps
R v. Darrach, 2000 SCC 46
Social media communications can be admissible if properly authenticated.
R v. Wong, 2019 ONCA 631
Snapchat messages were admissible after proving authenticity and relevance.
4. Principles for Admitting Electronic Evidence
A. Authentication
Identify the sender/source (emails, texts, social media accounts).
Prove integrity (no tampering or deletion).
Use expert testimony or metadata where necessary.
B. Relevance
The electronic evidence must have a logical connection to a fact in issue.
C. Hearsay Exceptions
Business records, statements against interest, admissions of a party.
D. Reliability
Courts may consider technical reliability and method of extraction.
Example: Forensic imaging of hard drives is often required to maintain reliability.
E. Charter Considerations
Evidence must be obtained in accordance with the Charter of Rights and Freedoms, particularly sections 8–11.
5. Practical Examples
| Type of Evidence | Admissibility Consideration | Case Example |
|---|---|---|
| Authentication of sender & integrity | R v. Wong | |
| Text message | Chain of custody, relevance | R v. Darrach |
| Social media post | Relevance, authentication | R v. Wong |
| Computer files | Forensic extraction, integrity | R v. Vu |
| Surveillance footage | Authenticity and reliability | R v. Cole |
6. Challenges in Practice
Rapidly Changing Technology – New apps, encryption, and cloud storage pose new evidentiary issues.
Volume of Data – Courts may require summaries or expert reports.
Metadata Issues – Dates, times, GPS, and IP addresses must be verified.
Cross-Border Data – Obtaining data from servers outside Canada can involve legal complications.
7. Summary
Electronic evidence is admissible if it is authentic, relevant, reliable, and obtained legally.
Courts carefully consider privacy rights and Charter protections.
Business and routine records in electronic form are treated similarly to paper records.
Prosecution must establish chain of custody and show evidence integrity.
Key Takeaways:
Authentication is critical.
Reliability is scrutinized.
Charter rights can exclude improperly obtained digital evidence.
Hybrid evidence (business + personal) requires careful procedural handling.
