Canada has introduced several important federal rule changes in May 2026, impacting taxpayers, public service workers, financial institutions, and specific beneficiary groups. While some updates apply broadly, others are sector-specific, meaning their effect depends on individual circumstances.
Below is a simplified and SEO-optimized breakdown of the most important updates Canadians should know.
🏛️ 1. Federal Public Service Onsite Work Mandate
Starting May 4, 2026, federal executives in the EX category must work onsite five days per week. This applies to core federal departments such as CBSA, Health Canada, and others.
A broader policy requiring most federal employees to work onsite at least four days a week is expected from July 2026.

🧾 2. CRA Year-Round Tax Review System
The Canada Revenue Agency (CRA) has moved to a year-round post-assessment review system for 2025 tax returns.
This means taxpayers may receive review notices at any time—not just during tax season.
You may be asked to provide proof for:
- Medical expenses
- Childcare claims
- Tuition and education credits
- Employment expenses
📌 Important: These reviews are routine checks, not full audits.

💰 3. CRA Interest on Unpaid Taxes
From May 1, 2026, unpaid tax balances from 2025 will accumulate daily compound interest at 7% annually.
Even if your tax return was filed on time, any unpaid balance after April 30 will start generating interest immediately.
📌 Tip: Paying early reduces total interest significantly.

- $4 per prescription
- 30% cost for dental, vision, counselling, physiotherapy, and medical equipment
Basic services like hospital visits remain fully covered.
