Canada has introduced sweeping changes to the authority and operational structure of its immigration officers, following the release of the latest Instrument of Designation and Delegation (IDD) on January 16, 2026. These changes, approved by Immigration Minister Lena Diab and effective retroactively from December 15, 2025, are designed to optimize decision-making, improve service delivery, and enhance operational efficiency across Immigration, Refugees and Citizenship Canada (IRCC), the Canada Border Services Agency (CBSA), and the Royal Canadian Mounted Police (RCMP).
