A Case Study in Workers’ Compensation Advocacy
TTD Benefits Reinstated After Psychological Claim Review — Former Police Officer
with PTSD
DRDRB Decision Date: November 4, 2024
I. Introduction
At Blue Collar Consulting, we know that psychological injuries do not resolve simply because they go undocumented. A compensable condition that goes untreated for a period does not become a non-compensable one. And an original workplace injury does not lose its status simply because subsequent stressors have made things worse. This is the story of a former Edmonton Police Service officer whose accepted compensable PTSD was denied WCB coverage on the basis that his psychological deterioration was linked to events in Manitoba rather than to the original Alberta injury. We appealed. The DRDRB agreed in part, confirming that his compensable psychological conditions remained the dominant cause of his work disability and awarding TTD benefits from November 24, 2023 forward.
What follows is not just the account of one review. It is a demonstration of the principles that govern psychological injury claims when life outside of Alberta complicates the picture: the dominant cause analysis, the chronic and cumulative nature of PTSD, and the importance of ensuring that WCB’s responsibility for an accepted condition is not shed simply because subsequent experiences have added to an already-disabling burden.
II. Background of the Worker’s Case
Our client served with the Edmonton Police Service and was exposed, in the course of that service, to traumatic incidents that gave rise to a diagnosis of chronic PTSD and Major Depressive Disorder. Those conditions were accepted as compensable by WCB Alberta. They were real, clinically documented, and directly connected to what he had witnessed and endured while serving the public in one of the most demanding roles in law enforcement.
After leaving policing, he continued to live with the consequences of those exposures. He subsequently worked in Manitoba, where he experienced further traumatic events in the course of that employment. His psychological condition, already compromised and never fully resolved, deteriorated further. When he sought WCB Alberta support, the Board denied his temporary total disability benefits. The denial was grounded in the assertion that his psychological deterioration was linked to the Manitoba events — not to the original Alberta compensable injury.
That position fundamentally misunderstood the nature of chronic PTSD and the relationship between the original Alberta injury and the subsequent deterioration. A condition that was never fully resolved does not become a new condition when subsequent stressors make it worse. The original compensable injury remained the foundation of our client’s psychological disability. Blue Collar Consulting stepped in to make that argument, and to ensure the DRDRB evaluated the claim through the correct analytical lens.
III. The TTD Benefits Dispute
- WCB’s Position
WCB denied TTD benefits on the grounds that the worker’s psychological deterioration was caused by the events he had experienced in Manitoba rather than by the original Alberta compensable injury. The Board’s reasoning treated the Manitoba exposures as if they were an independent and intervening cause of a new psychological condition, severing the connection to the original Alberta PTSD diagnosis.
This reasoning misapplied the relevant analytical framework in two important ways. First, it treated the Manitoba exposures as a causative event rather than an aggravating one. An event that worsens a pre-existing condition does not create a new condition — it adds to an existing one. The original Alberta compensable PTSD had never fully resolved. The Manitoba experiences had made it worse. That is aggravation, not causation. Second, the Board’s approach failed to apply the dominant cause analysis correctly. The relevant question was not whether the Manitoba events had contributed to the deterioration — it was whether the original Alberta compensable PTSD remained the dominant cause of the worker’s disability. It did.
- Blue Collar’s Advocacy
We appealed the denial to the DRDRB, confronting the evidentiary challenge directly and building our case around the chronic nature of PTSD and the dominant cause analysis.
Our first argument addressed the gaps in the treatment history. We acknowledged that the documentation of the worker’s condition in the period between his departure from the Edmonton Police Service and the deterioration of his condition was incomplete. However, we submitted medical opinions establishing that his PTSD had never clinically resolved — it had simply been unaddressed. A condition that is not treated is not a condition that has resolved, and WCB’s implicit suggestion that the absence of treatment records meant an absence of ongoing disability was not supported by the clinical evidence.
Our second argument addressed the dominant cause question directly. Even accepting that the Manitoba experiences had contributed to the deterioration of our client’s condition, the original Alberta compensable PTSD remained the dominant cause of his psychological vulnerability and his ongoing disability. The Manitoba events had activated and worsened a condition that WCB Alberta had already accepted responsibility for. They did not create a new one. WCB’s responsibility followed the dominant cause — and the dominant cause was the original compensable injury.
Third, we presented medical evidence establishing that as of November 24, 2023, our client was clearly unfit for any form of work as a result of his accepted psychological injuries. Whatever the cause of the deterioration in the preceding months, the evidence of disability at that point in time was not in serious dispute, and we asked the DRDRB to award TTD benefits from that date forward.
- Evidence Considered
- Medical opinions confirming that the worker’s PTSD had never clinically resolved following his service with the Edmonton Police Service, establishing the continuity of the original compensable condition through the period in question.
- Evidence that the traumatic exposures in Manitoba constituted an aggravation of the preexisting compensable PTSD rather than an independent cause of a new psychological condition, supporting the dominant cause analysis.
- Medical evidence establishing that as of November 24, 2023, the worker was clearly unfit for any form of employment due to his accepted psychological injuries, supporting the award of TTD benefits from that date.
- Submissions on the chronic and cumulative nature of PTSD, explaining why the absence of contemporaneous treatment records in an earlier period did not support an inference that the condition had resolved.
- The Decision
The DRDRB agreed in part. While benefits were not awarded retroactively to May 2022 — the panel found insufficient contemporaneous medical documentation to support disability at that earlier point — it accepted that the worker’s compensable psychological conditions remained the dominant cause of his work disability. The panel found that as of November 24, 2023, the worker was clearly unfit for work due to his accepted psychological injuries, and awarded TTD benefits from that date forward.
The decision acknowledged what WCB had failed to recognise: that chronic psychological conditions like PTSD can cause long-term disability that is not negated by gaps in treatment history or by the presence of subsequent aggravating stressors. The dominant cause remained the original compensable injury, and WCB’s responsibility followed it.
IV. Policy and Legal Context
This case engaged several important principles in psychological injury adjudication.
- Dominant cause analysis: Where a worker’s disability has both a compensable origin and subsequent non-compensable aggravating factors, the relevant question is which is the dominant cause of the disability. Where the original compensable condition is dominant, WCB’s responsibility follows it regardless of what else has contributed to the deterioration.
- Chronic and cumulative nature of PTSD: PTSD is not a condition that resolves and resets. It accumulates. An original compensable PTSD diagnosis creates a psychological vulnerability that subsequent stressors can activate and worsen. WCB must account for the chronic nature of psychological injuries when assessing ongoing disability and the relationship between accepted conditions and subsequent deterioration.
- Aggravation versus new injury: An event that worsens a pre-existing compensable condition does not create a new condition — it aggravates an existing one. Where the original compensable condition was already disabling, subsequent aggravation by noncompensable events does not transfer responsibility from WCB to another jurisdiction or source.
- Treatment gaps do not extinguish entitlement: The absence of contemporaneous treatment records does not establish that a compensable condition has resolved. Where medical evidence confirms ongoing disability, the condition is ongoing regardless of whether it was being actively treated during a particular period.
V. The Broader Implications
This case matters beyond the individual outcome. It reinforces principles that are essential for workers with complex psychological injury histories.
- 1. PTSD does not resolve simply because it goes undocumented. Workers with accepted psychological injuries who have periods of limited treatment should not assume their entitlement has lapsed. The condition and its consequences may be ongoing regardless of the treatment record, and medical evidence of ongoing disability can establish continuity of entitlement even across gaps in documentation.
- 2. Out-of-province stressors do not automatically end Alberta WCB responsibility. Where a worker with an accepted Alberta compensable PTSD diagnosis experiences further traumatic events in another province, those events do not automatically sever WCB Alberta’s responsibility. The dominant cause analysis must be applied, and where the original Alberta injury remains dominant, the responsibility remains.
- 3. Partial wins are still wins. In this case, benefits were not awarded for the full period sought. But TTD benefits from November 24, 2023 forward represented a meaningful and significant outcome for a worker who had been denied entirely. Partial victories in complex psychological injury cases should not be dismissed — they provide both immediate financial relief and a foundation for further claims.
- 4. The chronic nature of psychological injury must be argued explicitly. WCB and review bodies do not always apply the correct framework to chronic psychological conditions. Advocates must make the argument explicitly: this is a chronic condition, it does not resolve between episodes, and the absence of treatment records is not evidence of resolution.
VI. Advocacy Lessons
- Address the treatment gap head-on. Rather than hoping the review body will overlook gaps in the treatment history, advocates should address them directly and explain why they do not support an inference of resolution. Medical evidence of ongoing disability is the answer to a treatment gap — obtain it, present it, and explain its significance.
- Apply the dominant cause framework explicitly. In cases where multiple causes or jurisdictions are in play, the dominant cause analysis must be named, cited, and applied in submissions. Advocates should not leave it to the review body to identify the right framework — they should provide it, with evidence supporting each element.
- Frame subsequent stressors as aggravation, not causation. When WCB argues that outof-province or non-occupational events caused a psychological deterioration, advocates must reframe the analysis: those events aggravated a pre-existing compensable condition; they did not create a new one. The characterisation of subsequent events as aggravation rather than causation is legally and practically significant.
- Build toward the clearest point of disability. In cases where retroactive benefits are difficult to establish due to documentation gaps, advocates should build the strongest possible case for benefits from the point at which disability is most clearly evidenced. A forward-looking award is better than no award, and it establishes a base from which future claims can proceed.
VII. Conclusion
This was a complex case involving a dedicated public servant whose years of service with the Edmonton Police Service had left him with a psychological injury that never truly healed. WCB’s denial — based on the assertion that Manitoba events had caused his deterioration — did not reflect the clinical reality of chronic PTSD or the dominant cause framework that governs these claims. The DRDRB corrected that, at least in part, confirming that the original compensable condition remained the dominant cause of his disability and awarding TTD benefits from November 24, 2023 forward.
At Blue Collar Consulting, we are proud to have advanced this case and secured a meaningful outcome for a worker who had already given so much. For workers with complex psychological injury histories, this case is a reminder that WCB’s responsibility does not end because the path from original injury to current disability is complicated. If the original compensable condition is the dominant cause, the responsibility follows. We are here to make that argument.
This case underscores a truth that the workers’ compensation system must never forget: psychological injuries sustained in service to the public are real, they are lasting, and they deserve the same rigorous protection as any physical injury. Blue Collar Consulting exists to ensure that protection is enforced.
