The CRA denied a taxpayer with multiple health issues the disability tax credit, sparking a legal battle. The case highlights the complex criteria for eligibility and the challenges faced by individuals with disabilities. The taxpayer, who has a history of foster care and homelessness, worked as an apprentice electrician and faced challenges with frequent bathroom breaks and gastric conditions. Her doctor noted her ADHD and the time it took to manage bowel functions, but the judge ruled that her conditions did not meet the 'markedly restricted' threshold for eligibility. The decision underscores the importance of understanding the criteria for disability tax credits and the potential impact on individuals' financial well-being.
