Workplace investigations generate a paper trail that extends far beyond the final report. From the moment an employer receives a complaint, every note taken, every email exchanged, and every draft revised becomes part of a broader record that may one day be scrutinized by adjudicators, regulators, opposing counsel, or the parties themselves. Understanding how privilege, disclosure obligations, and record protection intersect is essential for any HR professional or employer seeking to conduct investigations that are both legally defensible and practically effective. The stakes are significant: a misunderstanding about what must be disclosed, what can be withheld, and how to protect sensitive information can undermine an otherwise thorough investigation and expose the organization to liability it might otherwise have avoided.
The concept of privilege in the investigation context refers primarily to solicitor-client privilege and litigation privilege, two related but distinct protections that shield certain communications and documents from disclosure. Solicitor-client privilege protects confidential communications between a lawyer and their client made for the purpose of seeking or providing legal advice. This privilege belongs to the client, not the lawyer, and can only be waived by the client. Litigation privilege, by contrast, protects documents and communications created for the dominant purpose of preparing for litigation that is reasonably anticipated or already underway. While solicitor-client privilege can exist indefinitely, litigation privilege expires when the litigation concludes. Both forms of privilege are recognized across Canadian jurisdictions, though their application in workplace investigations requires careful analysis of the specific circumstances.
