Mental health is now the leading cause of long-term disability in Canada. That's not a trend on the horizon - it's the reality employers are managing right now, in their workplaces, on their claims files, and in conversations with HR teams and benefit providers.

For many employers, mental health claims remain one of the most challenging areas to navigate: difficult to quantify, sensitive to manage, and often poorly understood in terms of what functional limitations actually look like and what recovery realistically involves.

This blog is for those employers - the ones who want to do this better.

What makes mental health claims different

Unlike many physical injury claims, mental health claims often don't come with clear-cut diagnostic findings, objective test results, or well-defined recovery timelines. There's no X-ray that shows the severity of major depression. There's no imaging that reveals the functional impact of a panic disorder.

This ambiguity creates real challenges:

• Employers struggle to understand what the person can and cannot do
• Return-to-work conversations become difficult without clear functional guidance
• Managers may inadvertently say or do the wrong thing, either pushing too hard or not providing enough structure
• Claims can extend unnecessarily when there is no clear evidence base for planning

None of these challenges are insurmountable - but they do require a more thoughtful approach than standard injury claims.

What employers actually need to know

Mental health claims are not inherently about 'weakness' or 'not trying.' They are about functional impairment - a person's ability to sustain the cognitive, emotional, and social demands of work. The goal is never to dismiss or minimize that impairment, but to understand it clearly so that meaningful support and realistic planning can happen.

Here's what matters most in the early stages of a mental health claim:

Get objective clinical input early. Functional limitations in mental health claims need to be established by qualified assessors - not assumed, not guessed, and not simply taken from a treating physician's note. An independent assessment helps clarify what the person can realistically do and under what conditions.

Avoid the extremes. Pushing for immediate return to full duties when someone isn't ready can worsen the condition and the claim. Allowing indefinite absence without a structured recovery plan can also extend duration unnecessarily. Graduated, supported return-to-work with clear milestones is typically the most effective pathway.

Address workplace factors. Mental health claims often have a workplace component - whether it's high demand, poor relationships, organizational change, or a specific traumatic event. Ignoring that context doesn't make it go away. Acknowledging it, and where possible addressing it, is part of a functional recovery plan.

Stay connected - appropriately. Maintaining regular, respectful contact with an employee on a mental health leave is associated with better return-to-work outcomes. But the nature of that contact matters. It should be supportive, not pressuring, and focused on the person's wellbeing rather than administrative timelines.

Where independent medical assessment fits in

Independent medical examinations play a specific and valuable role in mental health claims - one that is distinct from treating care.

An IME in this context provides:

• A clinically grounded, objective opinion on diagnosis and functional impact
• Clear guidance on work tolerances and limitations in mental health-specific terms (e.g., sustained concentration, emotional regulation demands, social interaction tolerance)
• Realistic assessment of prognosis and return-to-work timeline
• Identification of barriers to recovery that may not have been addressed in treatment

This gives employers - and their HR, legal, and benefit teams - a defensible, evidence-based foundation for decisions that can be difficult to make.

The bottom line

Mental health claims are complex, but they are not unmanageable. With the right information, the right support, and a structured approach grounded in objective evidence, employers can navigate these claims more effectively - for the benefit of the individual and the organization.

At IMA Solutions, we work with employers and insurers across Western Canada to provide the kind of clear, clinically rigorous assessment that makes a difference in mental health claims management.
