CRA Denied Taxpayer with Multiple Health Issues the Disability Tax Credit

Why It Matters

The ruling highlights the CRA’s strict definition of “markedly restricted” activities, limiting access to a credit that can save Canadians up to $2,340 USD a year and raising the evidentiary bar for future disability tax credit appeals.

Key Takeaways

• CRA requires "markedly restricted" daily activities for DTC eligibility
• Frequent bathroom trips alone insufficient without prolonged duration
• ADHD must significantly impair mental functions to qualify
• Judge upheld strict interpretation, denying credit for 2014‑2018
• Federal DTC worth about $1,070 USD annually

Pulse Analysis

The Disability Tax Credit remains one of Canada’s most valuable non‑refundable credits, designed to offset the hidden costs of severe and prolonged impairments. For 2025 the federal portion translates to roughly $1,470 CAD, or about $1,070 USD, while provincial add‑ons can push the total benefit to $3,200 CAD (approximately $2,340 USD). This credit can make a decisive difference for low‑income households, reducing tax liability and freeing cash for medical expenses.

In the recent Tax Court case, the judge applied a literal reading of the Income Tax Act’s “markedly restricted” standard. He measured the claimant’s bathroom frequency against typical usage and found no evidence of an inordinate time burden. Likewise, the claimant’s continued employment as an apprentice electrician demonstrated that her ADHD did not prevent her from performing essential mental functions such as concentration, judgment, and problem‑solving. The decision underscores that anecdotal hardship alone does not satisfy the statutory threshold; concrete, quantifiable evidence of severe limitation is required.

The outcome sends a clear signal to disability claimants and tax advisors: documentation must detail not only the presence of a condition but also its measurable impact on daily living and work capacity. Professionals should gather time‑studies, medical assessments, and functional assessments that align with the Act’s listed activities. As the CRA tightens scrutiny, policymakers may revisit the credit’s criteria to balance fiscal prudence with equitable support for Canadians facing genuine, debilitating challenges.
