The executive director of the community services agency stood at the edge of the parking lot on a grey October morning, watching a structural engineer photograph the crack that now ran the full height of the building's east wall. The crack had appeared gradually over four years, first as a hairline fracture that staff had dismissed as normal settling, then as something more troubling when the basement began taking on water during spring runoff. Now the engineer was telling her what the board had feared but not wanted to hear: the foundation work was deficient, the building envelope had been compromised, and the repairs would cost more than the original renovation. Inside that building, the agency ran transitional housing programs for women fleeing domestic violence, employment readiness training for newcomers to Canada, and after-school programming for children in low-income families. The executive director understood that pursuing the contractor who had performed the renovation was not simply a business decision; it was a question of stewardship, of whether the agency could continue to serve the populations that depended on it. What she did not yet understand was that the law offered her organization more than one path to the courthouse, and that choosing how to frame the claim would shape everything that followed.
When a plaintiff in Alberta considers commencing a civil action arising from deficient construction work, the most fundamental question is not whether something went wrong but rather what legal theory explains why the defendant should be held responsible for the plaintiff's loss. The two most commonly available theories in construction disputes are breach of contract and the tort of negligence, and while both can lead to the same courthouse and potentially to the same remedy of compensatory damages, they arise from different sources of obligation, require proof of different elements, and may reach different defendants. Understanding the distinction between contract and tort is essential for any claimant contemplating litigation because the choice of how to plead the claim affects who can be sued, what must be proven, which defences are available, and how damages are calculated. In many cases, including the one facing this community services agency, the plaintiff will plead both causes of action in the alternative, but doing so requires an appreciation of why the two theories are genuinely different and not merely interchangeable labels for the same complaint.
The law of contract is concerned with obligations that parties voluntarily assume toward one another through agreement. When the agency entered into a construction contract with the general contractor, both parties accepted a set of mutual obligations. The contractor promised to perform the renovation work in accordance with the plans and specifications, to complete the work within a certain timeframe, and presumably to perform the work in a good and workmanlike manner. The agency promised to pay the contract price according to an agreed schedule. These obligations exist because the parties created them through their agreement, and the source of the obligation is the contract itself. If the contractor fails to perform in accordance with the contract, the contractor is in breach, and the agency as the innocent party may claim damages to compensate it for the losses flowing from that breach. The agency does not need to prove that the contractor was careless or fell below some external standard of conduct; the agency need only prove that the contractor failed to do what the contractor promised to do. The standard against which performance is measured is the contract, and the existence of the contractual relationship between the parties is both the source of the obligation and a prerequisite to bringing the claim.
The tort of negligence operates on an entirely different foundation. Tort obligations are not created by agreement between the parties but are imposed by law upon persons who stand in certain relationships to one another. The classic formulation requires proof of four elements: the defendant owed the plaintiff a duty of care, the defendant breached that duty by failing to meet the applicable standard of care, the plaintiff suffered damage, and the defendant's breach caused that damage. The duty of care is not voluntarily assumed but arises because the law recognizes that certain activities and relationships create foreseeable risks of harm to identifiable persons. A general contractor performing construction work owes a duty of care to avoid causing reasonably foreseeable harm to persons and property. The standard of care is determined not by what the parties agreed to but by what a reasonable contractor in the same circumstances would have done. If the contractor's conduct falls below that standard and causes harm, the contractor is liable in negligence regardless of whether there was any contract between the parties at all.
For the community services agency, the distinction between contract and tort is not merely academic because the agency's relationship with the various parties involved in the renovation differs depending on which legal theory applies. The agency contracted directly with the general contractor. There is a written agreement setting out the scope of work, the price, and presumably some terms about the quality of performance expected. The agency can sue the general contractor for breach of that contract. The agency can also sue the general contractor in negligence because the general contractor owed the agency a duty of care that existed independently of the contract. These claims can be pleaded together, in the alternative, because they arise from the same factual circumstances but rest on different legal foundations. The contractor may have both broken the promises made in the contract and failed to meet the standard of care that a reasonable contractor would have met.
The situation becomes more complicated when the agency considers whether it has any claim against the subcontractor who actually performed the deficient foundation work. The agency never contracted with the subcontractor. The subcontractor was retained by the general contractor under a separate subcontract to which the agency was not a party. Under the doctrine of privity of contract, only parties to a contract can enforce the obligations created by that contract or be bound by them. The agency cannot sue the subcontractor for breach of contract because there is no contract between them. The subcontractor's contractual obligations run to the general contractor, not to the agency. If the agency wishes to pursue the subcontractor directly, it must find some basis for liability outside of contract law, and this is where the tort of negligence becomes essential.
The subcontractor may owe the agency a duty of care in tort even though the subcontractor has no contractual relationship with the agency. The analysis requires consideration of whether it was reasonably foreseeable that the subcontractor's negligent performance of the foundation work would cause harm to the agency, whether there was sufficient proximity between the subcontractor and the agency to give rise to a duty relationship, and whether there are any residual policy considerations that should negate or limit the duty. In construction cases, courts have consistently recognized that subcontractors owe duties of care to building owners with whom they have no direct contract because it is entirely foreseeable that deficient work will cause harm to the owner, the subcontractor knows that the work is being performed for the owner's benefit, and there are no compelling policy reasons to insulate subcontractors from liability to owners. The agency can therefore plead a claim in negligence against the subcontractor, alleging that the subcontractor owed a duty of care to perform the foundation work competently, that the subcontractor breached that duty by failing to meet the applicable standard of care, that the agency suffered damage as a result, and that the subcontractor's negligence caused that damage.
The practical consequence of this doctrinal distinction is that the agency's available causes of action depend on the identity of the defendant. Against the general contractor, the agency can plead both breach of contract and negligence, allowing it to rely on whichever theory proves more advantageous at trial. Against the subcontractor, the agency can plead only negligence because there is no contract to breach. This matters because the two theories differ in what the plaintiff must prove and what defences the defendant may raise. In a breach of contract claim, the plaintiff must prove the existence and terms of the contract, the defendant's failure to perform in accordance with those terms, and the damages flowing from the breach. The plaintiff does not need to prove that the defendant was careless or fell below an external standard; the plaintiff need only prove that the defendant did not do what the defendant promised to do. If the contract required the contractor to perform the work in accordance with the building code and the contractor failed to do so, that failure is a breach regardless of whether a reasonable contractor in the same circumstances might also have made the same error.
In a negligence claim, by contrast, the plaintiff must prove not only that something went wrong but that the defendant's conduct fell below the standard of care that a reasonable person in the defendant's position would have met. This requires evidence about what a competent practitioner would have done in the same circumstances, typically through expert testimony about industry standards and best practices. The defendant in a negligence action may argue that even if the outcome was unfortunate, the defendant's conduct was reasonable under the circumstances and therefore did not breach the standard of care. This defence is not available in a contract claim where the defendant clearly failed to perform a specific contractual obligation; the contract defines the standard, and departure from that standard is breach regardless of reasonableness.
The distinction between contract and tort also affects the assessment of damages. In a breach of contract claim, the governing principle is that the innocent party should be placed in the position it would have occupied had the contract been properly performed. This is sometimes called the expectation measure of damages because it aims to give the plaintiff the benefit of its bargain. If the contractor had performed properly, the building would have been renovated as specified, and the agency would have a functional facility. The damages include the cost of remedying the deficiencies, any consequential losses flowing from the breach such as the cost of alternative accommodations for programs or lost rental income, and potentially other foreseeable losses that were within the contemplation of the parties at the time of contracting. The limiting principle in contract is that damages must have been reasonably within the contemplation of the parties as the probable result of breach at the time they made the contract.
In a negligence claim, the governing principle is that the defendant should compensate the plaintiff for all losses that were reasonably foreseeable as a consequence of the defendant's negligence. This principle differs subtly from the contract measure because it focuses on what was foreseeable at the time of the negligent conduct rather than what was within the parties' contemplation at the time of contracting. In practice, the difference often makes little practical difference, but it can matter in cases involving unusual or particularly significant consequential losses. The agency operates programs serving vulnerable populations, and disruption to those programs may cause losses that extend beyond simple property damage. Whether those losses are recoverable may depend in part on how the claim is framed and what the relevant defendant knew or ought to have known about the agency's operations.
The executive director's review of the project file revealed another complication that would shape how the claim was pleaded. The agency's documentation from the time of the renovation was incomplete. The original contract with the general contractor existed, but the file contained few inspection reports, almost no correspondence addressing concerns raised during construction, and no formal records of any deficiencies identified at the time of substantial completion. The executive director had heard informally that there had been some water in the basement during the first year after the renovation, but the previous executive director had left the organization and the staff members who recalled the issue had only vague recollections. The current board chair remembered a conversation at a board meeting several years ago when someone had mentioned dampness in the basement, but the minutes from that meeting recorded only that the executive director would "look into maintenance issues" without any further detail.
This documentation gap matters because limitation periods in Alberta depend on when the claimant first knew, or ought reasonably to have known, that the injury had occurred, that it was attributable to the defendant's conduct, and that the injury warranted bringing a proceeding. Under the Limitations Act, a claim must be commenced within two years of the date the claim was discovered, and the claimant is deemed to have discovered the claim when it had actual knowledge of these matters or when a reasonable person in the claimant's circumstances ought to have had such knowledge. The Act also imposes an ultimate limitation period of ten years from the act or omission that caused the injury, after which no claim can be brought regardless of when it was discovered. For a construction deficiency that manifests gradually over time, determining when the limitation period began to run can be genuinely complicated, and the answer may differ depending on whether the claim is framed in contract or in tort.
In a contract claim, the cause of action typically accrues when the breach occurs, which in construction cases is usually when the deficient work is performed or when the building is completed. However, where the breach consists of latent defects that are not reasonably discoverable at the time of completion, the discoverability principle applies to postpone the running of the limitation period until the claimant knew or ought to have known of the deficiency. The agency might argue that the foundation defects were latent, not visible or detectable through reasonable inspection at the time of completion, and that the limitation period did not begin to run until the defects manifested in ways that a reasonable building owner would recognize as indicating a potential construction deficiency. The contractor might argue that signs of water infiltration four years ago should have put the agency on notice that something was wrong, and that a reasonable property owner would have investigated and discovered the foundation defects at that time.
In a negligence claim, the cause of action accrues when the plaintiff suffers damage, which again may not coincide with the time of the negligent conduct if the damage manifests only later. The same discoverability principles apply, and the same factual questions arise about when the agency knew or ought to have known that something was wrong. The analysis is functionally similar to the contract analysis, but the relevant date for the ultimate limitation period is the date of the negligent act or omission, which in construction cases is typically during the construction period. If the foundation work was performed more than ten years before the agency commences its claim, the ultimate limitation period may bar the claim against the subcontractor even if the defects were only recently discovered. This temporal analysis requires careful attention to exactly when the allegedly deficient work was done, and the agency's poor documentation makes that determination more difficult than it should be.
The involvement of the government funder adds another dimension to the agency's decision-making. The funder contributed capital toward the renovation and may have conditions attached to that funding that require the agency to maintain the building in good condition, to account for how the funds were used, or to report material issues affecting the funded asset. The funder may also have a financial interest in seeing the agency recover from the contractor or subcontractor because any recovery could reduce the cost of remediation that the funder might otherwise be called upon to support. The agency will need to consider whether commencing litigation affects its relationship with the funder, whether the funder might become involved in the litigation as an interested party, and whether any recovery must be shared with or reported to the funder under the terms of the funding agreement. These are not questions of causes of action but questions of stakeholder management that any sophisticated claimant must address before filing a statement of claim.
When the agency's board meets to decide whether to authorize litigation, the board will need to understand that pursuing both the general contractor and the subcontractor means invoking two different legal theories. Against the general contractor, the claim will plead breach of the construction contract and negligence in the alternative, allowing the agency to argue that the contractor both failed to perform as promised and failed to meet the standard of care that a reasonable contractor would have met. This dual pleading provides tactical flexibility because the agency can emphasize whichever theory is better supported by the evidence at trial, and the contractor cannot escape liability simply by showing that its conduct was reasonable if the agency can prove a clear departure from the contractual specifications. Against the subcontractor, the claim will plead negligence only, alleging that the subcontractor owed the agency a duty of care notwithstanding the absence of any contractual relationship, that the subcontractor's foundation work fell below the applicable standard of care, and that the agency's losses were caused by that negligence.
The general contractor will almost certainly respond by seeking contribution or indemnity from the subcontractor. If the agency succeeds against the general contractor on a theory that the contractor is responsible for the overall quality of the renovation, the contractor will argue that the subcontractor is the party truly at fault for the foundation defects and should bear all or part of the liability. This may result in the subcontractor being added to the litigation by the general contractor even if the agency had chosen not to sue the subcontractor directly. The resulting multi-party litigation will involve claims between the agency and the general contractor, claims between the agency and the subcontractor, and claims between the general contractor and the subcontractor, each resting on different legal foundations and each requiring proof of different elements.
The executive director understood by the end of her meeting with counsel that the path to the courthouse was not a single road but a network of routes, each with its own requirements and its own destinations. The agency could pursue the contractor who had promised to deliver a properly renovated building and had failed to keep that promise. The agency could pursue the subcontractor whose negligent work had caused the building to fail, even though the agency had never dealt with the subcontractor directly. The law provided these two paths because it recognized that obligations arise both from promises freely made and from the responsibilities that attend certain activities and relationships regardless of agreement. Both paths led to the same fundamental objective of obtaining compensation for the losses the agency had suffered, but the journey along each path required different proofs, faced different defences, and might yield different results. The board would need to decide which paths to pursue, knowing that the choice was not merely technical but would shape the entire course of the litigation to come.
