Expert Witness
Digital forensics expert witness services for Canadian courts.
Affidavits, expert reports, and trial testimony from expert examiners. Aligned to White Burgess and Mohan duties, and to BC Supreme Court Civil Rule 11.

When this service is needed
Typical scenarios where counsel and corporate clients retain us.
- Civil litigation requiring a retained expert
- Criminal proceedings (Crown or defence)
- Joint expert engagements
- Counter-analysis of an opposing expert's report
- Cross-examination preparation support
- Reply or rebuttal reports
How we approach it
A defensible, repeatable process.
Conflict check and engagement
We confirm there is no conflict of interest, sign a retention agreement that supports a litigation-privilege claim, and agree on scope.
Independent examination
We conduct the forensic work using the same methodology we apply to non-litigation engagements. Independence is the point. The work product is what it is.
Reporting
We deliver a draft report, walk counsel through it, and address scope-clarifying questions. The report names the methodology, the tools, the standards, and the limitations.
Affidavit and disclosure
For interlocutory matters, we provide an affidavit. For trial, we provide a Rule 11-compliant expert report and any supporting exhibits.
Trial testimony
We attend trial as an expert witness, present findings, and answer cross-examination. Preparation includes a pre-trial conference with counsel and review of opposing expert evidence if disclosed.

Common questions
Expert Witness questions from Canadian counsel and corporate clients.
What qualifications should a digital forensics expert have in BC?
There is no statutory licensing scheme. Courts assess qualification on the Mohan criteria (specialised knowledge, relevant credentials, prior testimony). Industry-recognized certifications (EnCE, CCE, CFCE, Cellebrite CCO/CCPA, Magnet MCFE, Vound Intella, AceLab PC-3000, AccessData FTK, BTL1) and a documented record of prior court testimony are the strongest credibility signals.
How does the White Burgess duty apply to a forensic expert?
White Burgess clarifies that an expert's duty to the court overrides any duty to the retaining party. An expert who cannot or will not give independent testimony is not admissible. Our reports are written to that standard, and the methodology is documented so a triggering inquiry can be answered without ambiguity.
What are the Mohan criteria for admissibility?
Established in R. v. Mohan, [1994] 2 SCR 9. Expert evidence is admissible if it is (1) necessary, in the sense of being likely to assist the trier of fact beyond ordinary experience; (2) relevant; (3) given by a properly qualified expert; and (4) not subject to an exclusionary rule.
Can a single expert serve in joint expert format?
Yes. Joint expert reports are common in BC family law and civil matters where parties want to avoid duelling-expert cost and complexity. We are willing to serve as a single expert when both parties consent and counsel agree to the protocol.
How is an expert affidavit different from an examiner report?
An affidavit is sworn evidence, typically used for interlocutory applications (injunctions, preservation orders, interim relief). An examiner report is a non-sworn document that explains methodology and findings. Many matters use both, with the affidavit attaching the examiner report as an exhibit.
What is the cost range for expert witness engagement?
Cost depends on scope. A single-device examination with a Rule 11 report is typically a defined-scope engagement. Multi-custodian, cloud-heavy, or trial-testimony matters are typically billed hourly with an estimate at scoping. We give a written estimate before any work begins.
