Physical and Documentary Evidence

Overview

A seized object, a recording and a spreadsheet raise different proof problems. Before presenting any of them, identify the fact to be proved, the connection between the exhibit and that fact, and the rule permitting its proposed use. A document may establish that particular words were communicated without establishing that those words were true. A genuine recording can still be too unclear to identify a person.

This lesson follows an item from collection to its use at trial. It connects the general admissibility framework with the separate questions taught in hearsay, identification and disclosure. The focus is ordinary Canadian criminal proceedings; a special statutory regime may impose additional conditions.

Learning Objectives

• Separate authentication, permitted evidentiary use and the weight of an exhibit.
• Select the applicable documentary or electronic-record route and its procedural safeguards.
• Analyze preservation problems and apply the appropriate response without assuming an automatic exclusion or stay.

Start with the Proposed Use

Connect an item to a disputed fact

An exhibit needs a demonstrated connection to the case. A jacket becomes useful evidence through facts about where it was found, who possessed it, and which characteristics matter. Producing a jacket resembling one described by a witness does not establish that the accused wore it. The party tendering it must supply the missing connections through admissible evidence or properly framed admissions.

The same discipline applies to documentary evidence. A handwritten note found in a room might help establish possession or knowledge of particular information. If its statement about an event is offered as proof that the event occurred, the court must also address hearsay. The physical discovery of the note cannot by itself prove the truth of its author's account. Specify the proposed inference before selecting an exception or asking the judge to receive the document.

Keep separate the item's identity, its information and the ultimate allegation. Authenticating a bank statement does not establish who directed a transaction. Proving that an access card opened a door does not necessarily identify its user. An argument about guilt must address the complete evidentiary record and the prosecution's burden, rather than treating the exhibit's admission as a finding on every disputed fact.

Distinguish usefulness from unfairness

The probative value of an item depends on its contribution to an actual issue. A photograph may clarify an injury, a location or an object's position. Its graphic character is relevant to the risk of unfair prejudice, particularly where repeated images invite emotion without adding information. The court considers the proposed use and available alternatives, including whether a less troubling image adequately conveys the relevant feature.

Evidence is not unfair merely because it damages a party's case. The concern is improper reasoning, confusion or unfairness in testing the material. The applicable balancing rule also depends on who tenders the evidence and the particular exclusionary rule. Do not transfer a prosecution-evidence formula uncritically to defence evidence. The general admissibility lesson develops that distinction; the physical form of an exhibit does not displace it.

Establish What the Court Is Seeing

Authentication and continuity

Authentication addresses whether an item is what the tendering party claims. Its foundation may include a witness who recognizes it, distinctive marks, records of its handling, or other circumstantial evidence. A party can challenge that foundation separately from arguing that the item deserves little weight. Identify the specific uncertainty: the wrong object, a substituted sample, an altered file, or simply incomplete information about storage.

The chain of custody should account for collection, transfer, storage, testing and production. Record seals, labels and changes that affect the relevant characteristics. Testing may legitimately consume or alter part of a sample; explain that process rather than implying that every change is misconduct. An intact seal and matching identifiers may support an inference of continuity even where a person who transported a package does not testify.

Neither an unexplained gap nor a missing signature has one automatic consequence. The judge assesses whether the foundation sufficiently connects this exhibit to the item claimed. A minor gap may affect weight; a serious uncertainty about identity or alteration may prevent admission. Even after admission, the trier of fact must consider remaining weaknesses when deciding what the item proves. JurisClasseur, fascicule 20, nos 1–6, supplies this distinction between the preliminary foundation and the final assessment.

The parties can narrow genuine disputes through admissions. In an indictable trial, section 655 of the Criminal Code permits the accused or counsel to admit a fact alleged against the accused to dispense with proof. State precisely what is admitted. An agreement that a photograph accurately shows a recovered object need not concede ownership, possession, intent or lawful police conduct.

Recordings and demonstrations

In R. v. Nikolovski, [1996] 3 SCR 1197, the Supreme Court recognized that an adequately established recording may itself provide identification evidence. A person who witnessed the offence need not invariably identify the accused before the trier of fact can use the images. The foundation and the quality of the recording still matter. Read the holding with its cautions, rather than treating every camera image as inherently conclusive.

The court must consider clarity, image quality, the depiction available and the possibility of a changed appearance. Where a recording supplies the sole identification evidence, the finding must still be proved beyond a reasonable doubt. A clear image of clothing with an obscured face raises a different problem from a clear facial image. The fact that software can enlarge an image does not establish that the enlarged picture contains reliable additional detail.

Where the jury is asked to identify the accused from the recording, the judge must direct it to assess clarity, quality and duration against the reasonable-doubt standard, and remind it if this is the only identification evidence. A judge sitting alone must apply the same cautions. The trier of fact must be able to review the recording during deliberations with the same or similar viewing equipment: Nikolovski, paras 30–32.

A diagram or reconstruction used to illustrate testimony also needs explanation. Distinguish observed features from assumptions introduced by its maker. Label a diagram that is not to scale and explain differences between a demonstration and the original conditions. Its persuasive visual appearance cannot supply facts that no witness or other admissible evidence establishes.

Choose a Documentary Route

Originals, copies and particular statutory conditions

The best evidence rule concerns proof of documentary contents. The traditional preference for an original operates alongside statutory routes permitting copies and the separate electronic-document provisions. It is inaccurate to say that every copy is inadmissible or that an original guarantees truthful contents. Explain what original exists, why a copy is tendered, how it was made and which legal route supports it.

The Canada Evidence Act supplies several routes with different conditions. Sections 23–27 address specified judicial, public and other records. A certified copy that satisfies the applicable provision can remove the need to prove the official signature or seal. Section 24 nevertheless starts from a case in which the original could be admitted. Certification does not give every statement in any official-looking document unrestricted evidentiary effect.

Section 28 requires reasonable notice before trial for copies tendered under sections 23–27, with a minimum of seven days. Section 29 separately addresses financial-institution records and the foundation for a true copy of an ordinary-course entry in records within the institution's custody or control. Its conditions should be checked directly instead of borrowing the notice and proof requirements of another provision.

Handwriting may also require proof. Section 8 permits witnesses to compare disputed writing with writing proved genuine to the court's satisfaction. A specimen of uncertain origin does not become a reliable comparator merely because counsel calls it a known signature. Explain how each specimen is connected to its supposed writer and identify the limits of the comparison.

Business records and information within them

A business record tendered under section 30 must have been made in the usual and ordinary course of business and concern a matter for which oral evidence would be admissible. The statutory concept of business extends beyond profit-making enterprises. The mere fact that an organization keeps a document in its files does not establish those conditions for every passage it contains.

Section 30(10) excludes specified material from admission through that section, including records made during an investigation or inquiry, in obtaining or giving legal advice, or in contemplation of legal proceedings. Claimed privilege and other listed exclusions also matter. Examine the creation and purpose of the particular entry. A routine dispatch entry and an investigator's later narrative about suspected wrongdoing do not acquire identical status by appearing in the same electronic folder.

Unless the court orders otherwise, section 30(7) requires notice to every other party at least seven days before production. The producing party must also make the record or affidavit available for inspection within five days after receiving another party's notice requesting inspection. This is a production obligation, not a deadline requiring the requesting party to complete its inspection. Subsections (5) and (6) allow scrutiny of other parts of the record and the circumstances of its creation, storage and reproduction. A selective extract can therefore require additional context. Under subsection (9), examination or cross-examination of a person with, or reasonably expected to have, knowledge of the record requires leave, subject to section 4.

Where a party relies on section 30(3) to produce a copy because producing the record is impossible or not reasonably practicable, two supporting documents are required. One explains the inability to produce the record; the other, made by the copy's maker, identifies its source and attests to its authenticity. Each must satisfy the provision's affidavit or foreign-law certification requirements. Subsection (4) separately governs a transcript explaining a record kept in a form the court cannot otherwise understand, with a supporting document in the prescribed form establishing the explainer's qualifications and attesting to the explanation's accuracy. Identify the route actually used; convenience alone does not establish these conditions.

Sections 30(11) and 36 preserve other admissibility routes. Failure under one statutory provision does not itself decide every alternative, but an alternative must actually be established. Calling material reliable is not a substitute for satisfying the conditions of the applicable common-law exception. Nor does compliance with an evidentiary provision authorize access to privileged or otherwise protected records.

Certificates and reports

Special statutory provisions may permit proof through an affidavit, solemn declaration, certificate or report. Their safeguards differ. Section 657.1 of the Criminal Code allows specified property and value facts to be proved by an affidavit or solemn declaration containing the statements required by subsection (2). Its maker must claim lawful ownership or entitlement to possession, or have specialized knowledge of the property or its type. Its evidentiary effect is subject to contrary evidence. Unless the court orders otherwise, the prosecutor must give the accused a copy and reasonable notice before the trial or other proceeding. The court may require the signatory to attend for examination or cross-examination.

Section 657.2 has two defined uses. In a prosecution for possession of property obtained by an offence, another person's conviction or discharge for theft of that property proves, absent contrary evidence, that the property was stolen. In an accessory-after-the-fact prosecution, another person's conviction or discharge for the underlying offence similarly proves its commission. Neither route by itself proves the present accused's knowledge, participation or every other element of guilt.

Section 657.3 permits expert evidence by report with the required supporting affidavit or declaration where the court recognizes the expertise and the notice requirements are met. It also addresses attendance and distinct expert-witness notice obligations. The witness lesson explains expert qualification; putting an opinion into a signed report cannot avoid that inquiry.

For certificates under the current impaired-driving provisions, section 320.32 provides the governing route, including reasonable notice with a copy before trial and an application for attendance for cross-examination. The written application must identify the likely relevance of the proposed questioning; a copy must reach the prosecutor at least thirty days before its hearing, which must itself occur at least thirty days before trial. Identify the applicable certificate, facts and timetable from the actual provision. An older reference to the former impaired-driving certificate provisions should not be used as the present procedure.

Section 51 of the Controlled Drugs and Substances Act separately permits an analyst's qualifying certificate or report as proof of its statements in the absence of contrary evidence, with attendance for cross-examination available by leave. The statutory shortcut does not prove who possessed a substance or dispense with connecting the analyzed sample to the exhibit. In proceedings under that Act or its regulations, section 53 permits proof of continuity through the testimony, affidavit or solemn declaration of someone claiming to have possessed the exhibit. The court may require an affiant or declarant to attend for examination or cross-examination.

Apply the Electronic-Document Rules

Keep authenticity, integrity and truth separate

An electronic document engages sections 31.1–31.8 of the Canada Evidence Act. Section 31.1 places the authentication burden on the tendering party: there must be evidence capable of supporting a finding that the document is what it purports to be. This threshold does not require the judge to decide every dispute about authorship, accuracy or ultimate guilt in the tendering party's favour.

Under section 31.2, the best evidence requirement may be satisfied through proof of the integrity of the electronic-document system or an applicable prescribed presumption. Section 31.3 provides presumptions in the absence of contrary evidence, including specified proof about proper operation, storage by an adverse party, or ordinary-course storage by an independent non-party. The factual conditions must be established; a computer-generated appearance does not activate them automatically.

A printout has a specific route under section 31.2(2) where, absent contrary evidence, it has been manifestly or consistently acted on, relied on or used as a record of the stored information. Section 31.6 permits affidavit proof of specified matters. A party may cross-examine the deponent of such an affidavit introduced in evidence as of right if the deponent is an adverse party or under an adverse party's control; otherwise, leave is required. Section 31.7 preserves other admissibility rules, including hearsay.

Worked example: the annotated delivery record

Factual Scenario

In this hypothetical theft prosecution, a depot routinely records parcel scans. Its custodian exports an entry showing that parcel 84 was scanned out at 17:10. She explains the operating system, routine entries and export process; the export accurately reproduces the stored entry. To assist a police investigation already underway, a supervisor adds “taken by the accused” based only on another worker's account. The prosecution tenders both entries to prove the accused took the parcel. Assume applicable notice and inspection requirements were satisfied and no access or privilege issue arises.

Variation

The prosecution instead tenders the later note only to explain why investigators interviewed the accused, and does not offer it as proof that the accused took anything.

Preserve Access and a Fair Opportunity to Respond

Missing material and the proper remedy

Full answer and defence requires a meaningful opportunity to test relevant prosecution material. In R. v. La, [1997] 2 SCR 680, paras 16–27, the Supreme Court linked disclosure to preservation and required the Crown to explain missing evidence. Reasonableness depends on the circumstances, including the relevance apparent when the loss occurred. Greater apparent relevance calls for greater care.

A satisfactory explanation establishing absence of unacceptable negligence can discharge the disclosure duty. If that explanation is not established, a breach of the disclosure obligation follows. Deliberate destruction to defeat disclosure can also constitute an abuse of process; other sufficiently serious failures to preserve evidence can engage that separate inquiry without proof of an improper motive. In extraordinary circumstances, loss may independently impair trial fairness even where the disclosure duty was met; the accused must establish actual prejudice to full answer and defence on that route. Neither missing originals nor a proven breach automatically yields a stay. The proposed remedy must address the established problem under the remedies framework.

An objection should explain what testing became impossible, what substitutes survive and how the loss affects a disputed issue. If a sample was consumed during necessary testing, inspect the method, retained data and available opportunity to challenge the conclusions. Avoid asserting that the lost material would necessarily have exonerated the accused. The inability to determine its contents is often precisely the problem requiring analysis.

Controlled viewing and an intelligible record

Section 652 of the Criminal Code allows the judge, in the interests of justice, to direct a jury view after it is sworn and before verdict. The judge controls how the place, thing or person is shown and gives directions against improper communication. The provision requires the judge and accused to attend. A view is a judicial process, not permission for jurors to conduct private investigations.

At trial, identify the version displayed and preserve the relationship between an original exhibit, an extract and any illustrative enlargement. Ensure the opposing party can understand and challenge the material and that the record reveals the ruling and permitted use. This makes the trial reasoning assessable and preserves a meaningful record if the decision is appealed.

Practice Checklist

• Identify the disputed fact and each intended use of the object or record.
• Establish identity, continuity and relevant alterations or processing.
• Separate authenticity, system integrity, hearsay and final evidentiary weight.
• Select the exact statutory or common-law route, including notice and inspection.
• Separate routine records from investigative additions and embedded assertions.
• Identify any missing material, the explanation, resulting prejudice and appropriate response.
• Preserve an intelligible exhibit record and the court's limits on use.
