Privilege stands as one of the most powerful protections in Canadian litigation, shielding certain communications from disclosure even when they might otherwise be relevant to a legal dispute. For business owners and professionals navigating potential or active litigation, understanding what privilege covers, how it can be lost, and why it matters can mean the difference between protecting sensitive strategic discussions and having them exposed in court. This lesson examines the two most important forms of privilege in Canadian civil litigation: solicitor-client privilege, which protects confidential communications between lawyers and their clients, and settlement privilege, which encourages parties to negotiate freely without fear that their compromise positions will later be used against them.
The foundation of solicitor-client privilege rests on a simple but profound principle: people must be able to speak candidly with their lawyers without worrying that those conversations will be revealed to others. Canadian courts have recognized this privilege as a substantive legal right, not merely a rule of evidence, and have elevated it to near-constitutional status as essential to the proper functioning of the legal system. The rationale is practical. If clients feared that their admissions, questions, or strategic discussions with counsel might be disclosed to opposing parties or the public, they would withhold information from the very people trying to help them. Lawyers cannot provide sound advice without complete information, and clients cannot make informed decisions without being able to explore their legal exposure candidly. The privilege exists to remove this barrier, creating a zone of confidentiality that permits full and frank communication.
For solicitor-client privilege to attach, three conditions must be satisfied. First, the communication must be between a lawyer and a client, or between their respective agents for purposes of obtaining or giving legal advice. Second, the communication must have been made in confidence, meaning both parties understood and intended that it would not be shared beyond those who needed to know. Third, the communication must have been made for the purpose of seeking or providing legal advice. This third element matters greatly in business contexts, where interactions with lawyers may blend legal advice with business strategy, financial planning, or operational decisions. Only the portions of communication that relate to legal advice attract privilege; a lawyer who also provides business consulting cannot cloak general business discussions in privilege simply by virtue of being a lawyer. The Supreme Court of Canada has made clear that the privilege belongs to the client, not the lawyer, and only the client can waive it.
Litigation privilege operates somewhat differently, protecting communications and documents created for the dominant purpose of litigation that is ongoing or reasonably anticipated. Unlike solicitor-client privilege, litigation privilege is not limited to communications with lawyers. It can cover communications with third parties, such as investigators, experts, or witnesses, so long as they were prepared primarily for litigation purposes. This privilege recognizes that parties engaged in or preparing for litigation need a zone of privacy to develop their case strategy, gather evidence, and prepare their positions without immediate disclosure to opponents. However, litigation privilege is temporary. Once the litigation concludes, the privilege generally ends, whereas solicitor-client privilege continues indefinitely. For business owners, this distinction matters when considering what protection applies to various documents generated during a dispute.
Settlement privilege, sometimes called without prejudice privilege, serves a different but equally important function. It protects communications made in genuine attempts to settle a dispute, ensuring that parties can make offers, acknowledge weaknesses in their positions, and explore compromise without those admissions being used against them if negotiations fail. This privilege exists because society benefits when parties resolve disputes without court intervention. If every concession made in negotiations could later be entered as evidence, parties would never negotiate meaningfully. They would posture and deflect rather than engage honestly with the possibility of settlement. Settlement privilege removes this disincentive by creating a protected space for compromise.
The scope of settlement privilege extends to oral discussions, written communications, formal mediation sessions, and informal negotiations, provided they occur in a genuine attempt to resolve a dispute. The phrase "without prejudice" commonly appears on settlement correspondence as a signal that the parties intend the communication to be privileged, but the label alone does not guarantee protection. Courts look to the substance and context of communications, not merely their headers, in determining whether settlement privilege applies. A letter marked "without prejudice" that contains threats, accusations, or demands unrelated to settlement may not attract privilege. Conversely, genuine settlement discussions that omit the magic words may still be protected if their purpose was clearly to explore resolution.
Both privileges share an important characteristic: they can be waived, intentionally or inadvertently, by the party holding them. Waiver occurs when the privilege holder discloses the privileged communication to someone outside the privileged relationship in circumstances inconsistent with maintaining confidentiality. For solicitor-client privilege, this might happen when a business owner forwards legal advice emails to a consultant, posts about legal strategy on social media, or discusses lawyer communications in a meeting where non-privileged parties are present. Once privilege is waived for part of a communication, courts may find it waived for the entire subject matter, preventing selective disclosure that would distort the full picture. Business owners must therefore be cautious about who sees communications with counsel and in what contexts those communications are shared.
Settlement privilege can also be lost through waiver or through exceptions that courts have recognized. The most significant exception arises when the parties dispute whether a settlement was actually reached. If one party claims that negotiations concluded in a binding agreement while the other denies it, courts permit evidence of the settlement discussions to determine what, if anything, was agreed. Without this exception, parties could negotiate settlements and then refuse to honour them, knowing the negotiations could never be proved. Other exceptions exist where evidence of settlement discussions is necessary to establish the existence of a legal relationship, to prove that one party acted in bad faith during negotiations, or where a statement made in settlement discussions constitutes a threat or an abuse of process. These exceptions are narrow, and Canadian courts remain protective of settlement privilege to encourage the resolution of disputes without trial.
The professional context in which privilege issues arise for business owners often involves navigating who can be part of privileged conversations and what documentation practices preserve protection. When a business owner consults a lawyer about a potential contract dispute, the communications between them are privileged. But complications emerge when the business owner wants to involve others: an accountant who understands the financial aspects of the dispute, a manager who witnessed key events, or a board of directors that needs to approve litigation strategy. The question becomes whether including these additional parties destroys or preserves privilege.
Generally, communications with third parties fall outside solicitor-client privilege unless those parties serve as agents of the client for purposes of obtaining legal advice or agents of the lawyer for purposes of providing it. An accountant who interprets financial records so that the lawyer can understand them and provide legal advice may be included within the privilege. A manager whose participation is necessary for the client to fully instruct counsel may likewise be covered. However, merely copying a third party on correspondence with counsel because it would be convenient or informative typically does not extend privilege to those communications. Instead, it risks waiving privilege entirely. The safest approach involves careful consideration of who genuinely needs to participate in privileged communications and consulting with counsel about how to structure those interactions.
Consider the situation faced by a landscape design and construction business operating out of Saskatoon. The owner had contracted with a municipal government to design and install green infrastructure for a new community centre, a project valued at approximately $340,000. Disputes arose midway through the project when the municipality alleged that certain plantings failed to meet specifications and that drainage features did not function as warranted. The owner believed the municipality had changed requirements repeatedly and provided inadequate site preparation before the installation work began. Both parties retained lawyers and exchanged correspondence, some marked "without prejudice" and some not.
The owner's lawyer sent a letter offering to remediate specific plantings and adjust drainage grades at a cost of approximately $28,000 in labour and materials, to be borne by the landscape company, in full settlement of all claims. The municipality's lawyer responded, also on a without prejudice basis, acknowledging that some of the issues may have stemmed from site conditions but maintaining that the majority resulted from deficient workmanship. The municipal response proposed that the landscape company either complete specified remediation work and pay $15,000 toward the municipality's costs, or accept a mutual release with each party bearing its own costs and the remediation to be completed by a third party at municipal expense. The parties engaged in two telephone discussions following this exchange, during which the owner verbally proposed splitting the cost of remediation and having the work supervised by a joint representative. No agreement was reached.
Six weeks later, the municipality commenced an action seeking damages of approximately $85,000 for remediation costs, project delays, and related expenses. In its statement of claim, the municipality included allegations that the landscape company had acknowledged deficiencies in the work during settlement discussions and had offered remediation, which the municipality characterized as an admission of liability. The landscape company's lawyer immediately objected, asserting settlement privilege over the entire course of without prejudice negotiations. The municipal lawyer argued that by making certain statements in the negotiations, the landscape company had waived any privilege and that the acknowledgments were admissible evidence of liability.
This dispute over privilege became a preliminary motion before any determination of the underlying claims. The landscape company sought an order excluding all evidence of settlement discussions. The municipality resisted, arguing partial waiver and relevance. Understanding how courts approach such disputes illuminates the importance of privilege and its limits.
What this scenario reveals is that settlement privilege is robust but not absolute. Courts in Canada consistently hold that genuine settlement negotiations are protected, even when one party makes damaging admissions or proposes significant compromises. The whole point of settlement privilege is to allow such vulnerability without legal consequence if settlement fails. Marking correspondence "without prejudice" provides strong evidence that the parties intended their communications to be privileged, but courts examine the full context. In the Saskatoon scenario, the written exchanges and telephone discussions all occurred during active attempts to resolve the dispute. There was no concluded agreement whose existence was disputed, no allegation of bad faith or threat making, and no claim that any statement amounted to something outside the bounds of genuine negotiation. These factors strongly favoured upholding privilege.
The municipal argument that the landscape company waived privilege by acknowledging deficiencies misunderstands how waiver operates in this context. Making admissions or concessions within privileged negotiations does not waive the privilege that protects those negotiations. Waiver would occur if the landscape company had disclosed its settlement correspondence to third parties, referenced the content of without prejudice negotiations in non-privileged communications, or attempted to use selected portions of the negotiations while shielding others. Simply participating in the negotiations and making offers does not constitute waiver.
For business owners and professionals, this situation offers several practical insights. First, marking settlement correspondence "without prejudice" is advisable and establishes a clear record of intent, but it does not replace substantive protection. The underlying purpose of the communication matters. Second, verbal settlement discussions deserve the same protection as written ones, but they are harder to prove occurred and harder to prove were intended as genuine settlement attempts. Where possible, confirming the without prejudice nature of telephone negotiations by email or letter following the call creates useful documentation. Third, business owners should understand that privilege protects the communications themselves, not the underlying facts. If the landscape company performed deficient work, that fact remains provable through inspection of the work, expert evidence, and other non-privileged sources. Settlement privilege prevents the municipality from proving deficiency by pointing to what the landscape company said in negotiations, but it does not prevent proof through other means.
The implications extend to how business owners should structure communications with their lawyers and approach settlement negotiations. When consulting legal counsel about a dispute, the purpose should be clearly framed as seeking legal advice. Mixing legal consultations with general business meetings attended by multiple staff, some of whom have no role in the legal matter, risks diluting privilege. It may be prudent to schedule separate discussions for legal strategy, attended only by those whose presence is necessary, and to document those meetings in a manner that reflects their privileged nature.
When entering settlement negotiations, business owners should ensure their lawyer is involved or at least aware, as navigating what to offer and what to concede without creating unintended legal exposure requires legal judgment. Offers should be made in writing where possible, clearly marked without prejudice, and should avoid language that could be characterized as admissions independent of the settlement context. Saying "we will repair the identified deficiencies" in a settlement letter is different from saying "we acknowledge our work was deficient and breached the contract," even if both convey willingness to remediate. The framing matters.
Business owners should also ask their lawyers to explain the scope and limits of privilege in their specific situation. In British Columbia, Alberta, Saskatchewan, Ontario, and other common law provinces, the principles outlined above generally apply, governed by provincial evidence legislation such as the Evidence Act in British Columbia, the Alberta Evidence Act, the Saskatchewan Evidence Act, and the Ontario Evidence Act, as of the date of authorship, though the core principles derive from common law. Quebec, operating under the Civil Code of Quebec, recognizes professional secrecy as the analogous protection for communications between advocates and clients. Article 9 of the Quebec Charter of Human Rights and Freedoms explicitly protects professional secrecy, and the Civil Code reinforces this protection. Settlement privilege is likewise recognized in Quebec's civil procedure framework, supporting the amicable resolution of disputes. While the terminology and statutory foundations differ, the practical effects for business owners are similar: confidential communications with legal counsel and genuine settlement discussions enjoy protection from disclosure.
Several concrete steps flow from this understanding. Business owners facing potential litigation should establish early contact with legal counsel and conduct sensitive discussions within that relationship. They should limit the circulation of legal advice to those who genuinely need it and should avoid forwarding lawyer correspondence to accountants, consultants, or partners unless counsel confirms this is appropriate. They should maintain clear records of what communications occurred within privileged contexts and should, where feasible, separate legal strategy discussions from operational meetings.
When engaging in settlement negotiations, business owners should confirm at the outset that discussions are intended to be without prejudice and should document this intention in writing. They should avoid unilateral admissions outside the settlement context, recognizing that privilege protects negotiations but not separate statements made in ordinary business communications. If settlement discussions occur verbally, a follow-up email confirming that the conversation occurred on a without prejudice basis protects both parties.
Questions that business owners should ask their lawyers include whether particular communications fall within privilege, whether involving specific third parties might risk waiver, what documentation practices preserve protection, and what happens to privileged communications if the business is sold or if key personnel change. Understanding that privilege belongs to the client means business owners can make informed decisions about whether to waive it, as sometimes strategic disclosure is advantageous, but those decisions should be deliberate and counselled.
In summary, solicitor-client privilege and settlement privilege are foundational protections that enable candid legal advice and genuine negotiation. They are not obscure technicalities but practical shields that business owners invoke regularly, often without realizing it. When disputes arise, whether over contracts, employment, property, or any other matter, understanding what is protected, what is not, and how to preserve those protections allows business owners to make better decisions at each stage. Privilege encourages both seeking proper legal advice and exploring settlement options, outcomes that benefit individuals, businesses, and the legal system. For business owners navigating Canada's litigation landscape, mastering these concepts is essential to managing legal risk effectively.
