The executive director stood at the threshold of the basement storage room, watching a thin stream of water trace its way down the concrete wall and pool on the floor where it had already begun to warp the laminate flooring installed just three years earlier. Above her, she could hear the muffled sounds of the after-school program, children's voices echoing through a building that had been renovated specifically to serve them. She had noticed dampness in this corner six months ago, had mentioned it casually to the facilities manager, who had attributed it to condensation and suggested they run a dehumidifier. Now, with water actively infiltrating the wall and the unmistakable smell of mold beginning to permeate the space, she understood that the problem was something far more serious. What she did not yet understand was that this moment—standing in a basement watching water damage unfold—would become the subject of intense legal scrutiny, the fulcrum upon which a limitation period analysis would turn, and the focal point of a dispute that would consume the organization's attention for years to come.
The Limitations Act of Alberta establishes a framework that governs when claims must be brought and when they are forever barred. At the heart of this framework lies the basic limitation period: two years. This period appears simple on its face, a straightforward deadline that claimants must meet or forfeit their right to pursue remedies through the courts. Yet the apparent simplicity of a two-year window belies the considerable complexity that surrounds its application. The critical question is not merely how long the period runs but when it begins. Alberta law answers this question through the discoverability principle, which provides that the limitation period does not commence on the date when the wrongful act occurred, nor necessarily on the date when damage first manifested, but rather on the date when the claimant knew or ought to have known that the injury, loss, or damage had occurred, that it was caused by or contributed to by an act or omission, and that the act or omission was that of the defendant. This three-part test determines the moment of discovery, and from that moment, the clock begins its inexorable countdown.
For the non-profit community services agency standing in its water-damaged basement, the discoverability principle transforms what might seem like a simple timeline into a complicated factual inquiry. The renovation was completed three years ago. Water infiltration was first observed, in a minor form, six months ago. Active damage is occurring now. The executive director is learning of the severity today. The board will be informed at next month's meeting. A structural engineer, retained to investigate, will deliver a report eight weeks hence identifying the cause as improper waterproofing of the foundation—work performed not by the general contractor but by a subcontractor the general contractor retained. Each of these moments represents a potential starting point for the limitation period, and the legal consequences of selecting one over another are profound. Choose the wrong date, bring your claim too late, and the courthouse doors close permanently, regardless of the merits of your case.
The Limitations Act makes clear that a claimant is deemed to have knowledge when the claimant first knew or ought to have known of the matters that comprise the discovery test. The phrase "ought to have known" imports an objective standard, asking not merely what this particular claimant actually knew but what a reasonable person in the claimant's circumstances would have discovered through the exercise of reasonable diligence. This objective component prevents plaintiffs from burying their heads in the sand, ignoring obvious signs of a problem, and later claiming ignorance to extend the limitation period. It also creates significant uncertainty, because reasonable people can disagree about what level of investigation was required and when it should have been undertaken.
Consider the situation facing the executive director. When she first noticed dampness in the basement six months ago, was that observation sufficient to trigger her obligation to investigate further? The facilities manager's explanation—condensation, nothing to worry about—provided a plausible innocent explanation for the phenomenon. A reasonable person might well accept that explanation, at least initially. But a reasonable person might also have followed up, monitored the situation, or consulted an expert. The question of what reasonable diligence required in those circumstances will depend heavily on context. What did the executive director know about construction and building maintenance? What resources did the organization have available to investigate? Were there other signs—complaints from program participants about musty smells, visible staining, increases in humidity readings—that should have prompted further inquiry? The answers to these questions will determine whether the limitation period began running six months ago or whether it only commenced when the problem became undeniable.
The challenge becomes even more complex when one considers that the claimant in this case is not a natural person but an organization. Non-profit societies in Alberta are legal entities distinct from their members, directors, and officers. The society can sue and be sued in its own name. But a society, being an artificial legal construct, cannot itself know anything. Knowledge must be attributed to the organization through the knowledge of natural persons who act on its behalf. This attribution question—whose knowledge counts as the organization's knowledge—is critical to limitation period analysis and is frequently contested in litigation.
Generally speaking, the knowledge of directors, officers, and employees acting within the scope of their duties will be attributed to the organization. When the executive director observed water infiltration, she was performing her duties as the chief administrative officer of the agency. Her knowledge, acquired in that capacity, becomes the organization's knowledge for limitation purposes. But attribution is not always straightforward. What if the facilities manager—a lower-level employee—was the first to observe the problem and failed to report it to senior management? Does the organization know what its employees know, even if that knowledge never travels up the chain of command? What if a volunteer observed damage during a routine visit and mentioned it to no one in particular? What if a program participant complained to a staff member who dismissed the concern and documented nothing?
Courts have grappled with these questions, and the answers depend significantly on the particular facts. Where an employee acquires knowledge in the course of their duties and within the scope of their authority, that knowledge will generally be attributed to the employer. The rationale is that organizations should not benefit from poor internal communication; if an employee knows something relevant, the organization is deemed to know it as well, and the organization bears the burden of ensuring that information flows to decision-makers. This principle has significant implications for non-profit agencies, which often operate with lean staffing, heavy reliance on volunteers, and informal communication practices. The board that learns of a problem only when the executive director finally brings it to their attention may discover, to its dismay, that the limitation period began running long before—from the moment any employee acquired knowledge that met the discoverability test.
The scenario presented also involves a complication common in construction defect cases: the distinction between the manifestation of a problem and the identification of its cause. The executive director knows that water is entering the building. She does not yet know why. Until the structural engineer completes their investigation, the agency will not know that the waterproofing was defective, that this defect was the cause of the infiltration, or that the work was performed by a specific subcontractor. Does the limitation period begin when the symptom appears, or does it begin only when the cause is identified?
The Limitations Act addresses this question by requiring, as part of the discovery test, knowledge that the injury was caused by or contributed to by an act or omission. A claimant cannot be said to have discovered a claim until they know (or ought to know) not only that they have suffered harm but also that someone's conduct caused or contributed to that harm. In a case where the cause of damage is obscure, the limitation period will not begin running until the claimant has sufficient information to connect the damage to a wrongful act or omission. This does not mean that the claimant must have complete knowledge of every detail or must be able to prove their case before the clock starts. The standard is not certainty but rather sufficient information to recognize that a claim exists.
For the non-profit agency, this means that the limitation period likely did not begin the moment water was first observed in the basement. At that early stage, there was no basis to connect the moisture to any act or omission by the contractor or anyone else. Condensation, as the facilities manager suggested, was a plausible explanation that did not involve any wrongdoing. But as the situation progressed—as more water appeared, as the innocent explanation became less credible, as the need for professional investigation became apparent—the agency's obligation to take steps toward discovering the cause intensified. By the time the executive director stood watching water stream down the wall, it would be difficult to maintain that a reasonable person would not have suspected construction deficiencies and commenced investigation.
The identity of the wrongdoer presents another layer of complexity. The discoverability test requires knowledge that the act or omission was that of the defendant. In this case, the general contractor will predictably point to the subcontractor who performed the foundation work. The agency hired the general contractor, not the subcontractor; there may be no privity of contract between the agency and the subcontractor at all. To bring a claim against the general contractor, the agency must establish that the general contractor is responsible—either directly, for failing to supervise or coordinate the work, or vicariously, for the acts of those it retained. To bring a claim against the subcontractor (assuming such a claim is legally viable), the agency must identify the subcontractor as the party whose conduct caused the harm.
Courts have recognized that limitation periods may run differently against different defendants. The clock does not start running against a particular defendant until the claimant knew or ought to have known that the claim arose from that defendant's conduct. Where the identity of the responsible party is initially unclear, the limitation period against that party may commence later than the limitation period against another party whose involvement was evident from the start. This principle provides some protection for claimants navigating complex multi-party disputes, but it also requires claimants to act diligently in investigating the identity of potential defendants. A claimant cannot simply wait indefinitely to determine who is responsible; they must pursue that information with reasonable diligence.
For the non-profit agency, this means that once the agency knew or ought to have known that construction deficiencies were causing the damage, it had an obligation to take reasonable steps to determine who was responsible for those deficiencies. The structural engineer's report identifying the subcontractor's faulty waterproofing would satisfy the requirement as against the subcontractor. But if the agency had access to project records—contracts, drawings, inspection reports—that would have revealed the subcontractor's involvement earlier, the limitation period may have begun running before the engineer's report was received. Similarly, the limitation period against the general contractor may have commenced at an earlier point if the agency knew from the outset that the general contractor was responsible for the overall project and that any deficiencies in the work would be attributable, at least initially, to the party with whom the agency contracted.
The scenario notes that the agency did not document the project well at the time. This failure has profound implications for the limitation period analysis. Good documentation—contracts that specify the scope of work and identify subcontractors, photographs of work in progress, contemporaneous records of inspections and approvals, written communications with the contractor—provides a foundation for establishing when the agency knew what. In the absence of such documentation, both the agency and its adversaries will be left to reconstruct events from memory, with all the imprecision and self-serving interpretation that memory entails. The contractor may argue that the agency was told of certain issues at the time and chose not to address them. The agency may struggle to prove when particular problems first manifested. Witnesses will disagree about what was said, when, and to whom.
The absence of documentation also exposes the agency to arguments that it ought to have known of problems earlier than it actually did. If the contractor provided any kind of warranty, the terms of that warranty—including any requirements for inspection and notification—may be relevant. If the contractor invited the agency to inspect the work before final payment, and the agency failed to do so or conducted only a cursory review, that failure may be characterized as a lack of reasonable diligence. The agency cannot claim ignorance of defects that a reasonable inspection would have revealed. In construction defect cases, courts have consistently held that claimants bear some responsibility for monitoring the condition of their property and investigating potential problems when warning signs emerge.
The government funder that contributed capital toward the renovation presents yet another dimension of the case. Government funders often attach conditions to their grants, including requirements for reporting, documentation, and maintenance of funded assets. The funder may have conducted its own inspections or required the agency to provide reports on the project's progress. If those reports exist—and if they contain any references to concerns about the work—they may be evidence of what the agency knew and when. Moreover, the funder has its own interest in the outcome. If the agency fails to recover from the contractor because of limitation issues, the funder may have its own claim against the agency for failing to maintain the funded asset or for breaching the terms of the grant agreement. These considerations add pressure to the board's decision-making and underscore the importance of acting promptly once a potential claim is identified.
The board must now grapple with the limitation period question as part of its decision whether to pursue the contractor. This is not a question the board can answer on its own; it will require legal advice from counsel familiar with Alberta's Limitations Act and the jurisprudence interpreting the discoverability principle. Counsel will need to review whatever documentation exists, interview the executive director and other staff about what they observed and when, examine the contractor's records if they can be obtained, and assess whether the agency acted with reasonable diligence. If counsel concludes that the limitation period has already expired or is about to expire, the board may face an urgent decision about whether to commence proceedings immediately or risk losing the claim entirely.
Even if counsel believes the limitation period has not yet expired, the board should be alert to the risks of delay. Every day that passes without action is a day that can be pointed to as evidence of the agency's failure to diligently pursue its rights. Memories fade, documents are lost, witnesses become unavailable. The contractor may argue that the delay has caused prejudice, that evidence relevant to its defence has been lost, and that it would be unfair to permit the claim to proceed. While such arguments go to the merits rather than the limitation period, they can influence how a court views the equities of the case.
The Limitations Act also contains an ultimate limitation period of ten years from the date of the act or omission giving rise to the claim. This ultimate period operates as a backstop, extinguishing claims regardless of discoverability after a decade has passed. In construction defect cases, where problems may lie dormant for years before manifesting, the ultimate limitation period provides finality for contractors and builders. The non-profit agency's claim, arising from a renovation completed three years ago, is well within this ultimate period. But the board should understand that the two-year basic limitation period, running from discovery, is the more immediate concern.
The board must also consider the broader implications of the limitation period for its governance practices going forward. The scenario illustrates how poor documentation and informal communication can expose an organization to limitation period problems. A diligent board will ensure that significant capital projects are thoroughly documented, that contracts clearly define the parties' obligations, that inspections are conducted and recorded, and that any concerns about defective work are promptly investigated and reported. The board should also ensure that staff understand the importance of escalating concerns about building conditions to management, so that the organization can make informed decisions about whether to investigate and, if necessary, commence legal proceedings within the limitation period.
The limitation period question—when did someone first know something was wrong—turns out to be more complicated than it looks. The answer lies not in a single date but in a careful reconstruction of events, weighted by principles of reasonable diligence and attributable knowledge. For the non-profit agency standing in its water-damaged basement, the clock may have started running months ago, or it may be starting only now. The difference between those two scenarios may determine whether the agency has a viable claim or whether it must bear the cost of the contractor's deficient work on its own. The board's responsibility, confronting this uncertainty, is to act promptly and decisively—to gather information, seek legal advice, and make a reasoned decision about whether to pursue its rights while the window remains open. In limitation period cases, the worst outcome is not losing on the merits; it is losing without ever having the merits considered, because the claim was brought one day too late.
