Want to claim medical expenses on your taxes? Read this first

Key number: for the 2025 tax year medical expenses are claimable above the lesser of 3% of net income or $2,833, with a federal non-refundable credit of 15% on the excess. Home accessibility and multigenerational renovation credits provide up to 15% of eligible costs — up to $20,000 (max $3,000 credit) for Home Accessibility and up to $50,000 (max $7,500 refundable credit) for Multigenerational Renovations. Advises claiming on the lower-income spouse to maximize benefit, retaining receipts and prescriptions, and confirming provincially eligible items; elective cosmetic procedures are generally not claimable unless medically necessary.

Analysis

The tax-friction around medical expense claims creates predictable demand clusters that aren’t obvious at first glance: a spike in professional tax-prep and fintech usage ahead of filing deadlines, and a correlated seasonal lift in discretionary spending on home accessibility during spring/summer renovation cycles. These flows concentrate spend into two supplier groups — digital tax-platforms (high margin, scalable revenue) and physical retail/contracting channels (HD/LOW style) — producing asymmetric optionality where modest increases in claim take-up drive outsized revenue for software and installers.

A second-order but material effect is on the senior-care economics: tax-relievable accessibility and attendant-care spending reduces effective out-of-pocket cost, lowering the break-even for home-based care vs institutionalization and boosting demand for home-health providers and retrofit manufacturers over a multi-year aging wave. Conversely, provincial heterogeneity and CRA enforcement create idiosyncratic tail-risk — sudden tightening or clarification of eligible items can compress addressable spend by double-digits in affected provinces within a single budget cycle.

The near-term alpha window is concentrated: tax-prep adoption and documentation requirements create a 60–120 day catalytic period before/after filing deadlines, while renovation demand concentrates in the next 3–9 months. Monitor two catalysts — provincial policy tweaks (legislative bulletin or budget) and a CRA audit spike — that can reverse the trade quickly; absent those, exposure to digital tax services and home-renovation ecosystems offers convex upside with bounded downside over 6–12 months.

Key Decisions for Investors

• Long HD (Home Depot) 3–6 month call spread into spring renovation season: buy the 3–6 month at-the-money call, sell a higher strike to fund premium. Thesis: incremental uptake of accessibility renovations drives sales of specialty materials and installation services; reward skew ~3:1 if spring activity rebounds, risk limited to premium paid.
• Long INTU (Intuit) 0–3 month at-the-money call or call spread heading into filing season. Thesis: increased complexity and documentation needs boost TurboTax/ProAdvisor revenue and pricing power; asymmetric payoff if user-adoption ticks; downside = option premium (~100% loss of premium), upside = multi-handle % revenue beat for the quarter.
• Buy EXE.TO (Extendicare) shares or 12-month covered calls (to collect yield while holding exposure). Thesis: higher affordability for home care via tax offsets should lift demand for home-attendant services and modestly improve occupancy/mix over 6–12 months; reward target +20–30% (reversion to peers), risks = regulatory/wage pressure and provincial funding changes.
• Long SLF.TO (Sun Life) 6–12 month exposure (shares or long-dated calls) as a defensive play on rising demand for supplemental private plans among aging cohorts. Thesis: expanding private-pay services and increased documentation lead to higher ancillary product sales and fee revenue; catalyst window 6–18 months, risk = macro equity drawdown or adverse regulatory changes that compress insurance margins.
