7.2 Hearsay, Privilege, Opinion & Improperly Obtained Evidence

Beyond relevance and materiality, a paralegal must recognize several categories of evidence that trigger their own admissibility analysis: hearsay, privilege, opinion evidence, and evidence obtained through improper means. Each of these appears throughout Small Claims, POA, and tribunal practice, and each has its own vocabulary that the P1 exam tests precisely.

Hearsay: The Default Exclusion

Hearsay is an out-of-court statement, oral or written, offered to prove the truth of its contents, where the person who made the original statement (the declarant) is not before the court or tribunal to be cross-examined about it. Hearsay is presumptively inadmissible because the trier of fact cannot test the declarant's perception, memory, sincerity, or ability to narrate accurately through cross-examination.

Not every out-of-court statement is hearsay. A statement offered for a non-truth purpose, for example, to show only that the statement was made, or to show its effect on the person who heard it, rather than to prove the statement's content is true, falls outside the hearsay rule entirely.

Traditional Hearsay Exceptions

Over time, courts recognized fixed categories where hearsay is reliable enough to admit despite the lack of cross-examination:

• Business records, admissible under the Ontario Evidence Act (with a parallel Canada Evidence Act provision in matters governed by federal law), where the record was made in the usual and ordinary course of business
• Admissions, statements made by a party to the proceeding that are offered against that same party
• Statements against interest, where the declarant said something contrary to their own financial or legal interest at the time
• Res gestae or spontaneous utterances, statements made under the stress of a startling event, leaving little time for fabrication
• Prior consistent or inconsistent statements, used for narrow, specific purposes such as assessing credibility rather than proving the truth of the earlier statement
• Public and official documents, such as certain government records, admissible without calling the original author

The Principled Approach

Even where a statement does not fit a traditional category, or as a check on a traditional category, hearsay may still be admitted if it satisfies two conditions established through the modern principled approach: necessity (there is no reasonably available, better way to get this evidence before the trier of fact, often because the declarant is unavailable) and threshold reliability (the circumstances in which the statement was made provide enough assurance of trustworthiness that the trier of fact can meaningfully evaluate it despite the absence of cross-examination). The adjudicator acts as a gatekeeper on this question, resolving it as a preliminary matter much like the voir dire discussed in section 7.1.

Privilege

Privilege protects certain communications and documents from being disclosed or used as evidence, even though they may be entirely relevant, because the law values the confidentiality of the relationship or process more than the evidentiary benefit of disclosure.

Solicitor-Client Privilege

Solicitor-client privilege protects confidential communications between a client and their legal adviser made for the purpose of seeking or giving legal advice. Courts describe it as close to absolute: it survives the end of the retainer and even the death of the client, and it belongs to the client alone, who is the only party who can waive it. Confidentiality obligations for licensed paralegals providing legal services within their permitted scope of practice serve the same underlying purpose, protecting the client's ability to speak candidly, though the precise scope of privilege doctrine as applied to paralegal-client communications continues to develop; either way, a paralegal's duty of confidentiality to the client is treated as effectively absolute in practice.

Litigation Privilege

Litigation privilege protects documents and communications created for the dominant purpose of existing or reasonably contemplated litigation, such as witness statements gathered in preparation for trial or communications with a consulting expert before that expert is retained to testify. Unlike solicitor-client privilege, litigation privilege is temporary: it ends once the litigation (and closely related litigation) concludes.

Settlement Privilege

Communications made in a genuine attempt to settle a dispute, often labelled without prejudice, are protected by settlement privilege so that the sender's efforts to compromise cannot later be used against them if the negotiation fails and the matter proceeds to a hearing. The policy goal is to encourage frank, unguarded settlement discussions. Limited exceptions exist, for example, to prove that a settlement was actually reached, or where a competing public interest clearly outweighs the value of protecting the communication.

Waiver

Privilege belongs to the holder, typically the client, and can be waived expressly or by implication, such as by voluntarily disclosing a privileged communication to a third party or by relying on the substance of legal advice as part of a claim or defence.

Opinion Evidence

Lay Opinion

As a general rule, witnesses testify to facts they personally perceived, not conclusions or opinions drawn from those facts; opinion evidence is reserved for experts. Narrow exceptions exist where a lay opinion is really just a shorthand, compendious way of describing observed facts that would be hard to relate otherwise, such as an estimate of speed, an observation that someone appeared intoxicated, or identification of a familiar voice or handwriting.

Expert Opinion

Expert opinion evidence is admitted only where it satisfies four criteria: relevance to a fact in issue, necessity to assist the trier of fact with matters beyond its ordinary knowledge and experience, the absence of any other exclusionary rule, and a properly qualified expert. A further gatekeeping requirement examines the expert's independence and objectivity: an expert who is unwilling or unable to provide fair, impartial, and non-partisan opinion evidence, because they are effectively an advocate for the party who retained them, may be found unqualified to testify as an expert at all, or the lack of independence may reduce the weight given to their opinion once admitted.

Improperly Obtained Evidence

Where evidence is obtained in a manner that infringed a Charter right, typically through the conduct of a state actor such as a police officer or provincial offences officer, it may be excluded if admitting it would bring the administration of justice into disrepute. That analysis weighs the seriousness of the Charter-infringing conduct, the impact on the affected person's Charter-protected interests, and society's interest in having the case decided on its merits. This framework is chiefly engaged in POA and criminal-type proceedings involving state action.

In purely private civil or tribunal disputes between individuals or businesses, this Charter-based exclusionary framework generally does not apply, because there is no state action to trigger it. Evidence obtained through improper means in a private dispute, such as a document obtained through a breach of confidence or a covertly made recording, is not automatically excluded on that basis alone, though it remains subject to ordinary relevance, prejudice, and privilege analysis, and the manner in which it was obtained can still affect the weight given to it or the costs awarded at the end of the case.

Key Takeaways

• Hearsay is presumptively excluded because the declarant cannot be cross-examined, but traditional exceptions and the necessity/threshold-reliability principled approach can let it in
• Solicitor-client privilege is close to absolute and belongs to the client; litigation privilege is dominant-purpose based and expires with the litigation; settlement privilege protects genuine compromise communications
• Lay witnesses testify to facts, not opinions, subject to narrow shorthand exceptions; experts must clear relevance, necessity, an absence of exclusionary rules, proper qualification, and sufficient independence
• Charter-based exclusion for improperly obtained evidence is primarily a POA and criminal-law tool tied to state conduct, not a general feature of private civil or tribunal disputes
