If you want to learn more about the new Canada Groceries and Essentials Benefit (CGEB), including who qualifies, how much you could receive, and when payments are issued, visit Tax Service Canada’s Canada Groceries and Essentials Benefit Guide. This comprehensive resource explains the eligibility requirements, payment amounts for individuals and families, application details for new residents, and important CRA payment dates.

If you receive the Guaranteed Income Supplement (GIS), now is the time to ensure your benefits continue without interruption. GIS eligibility is reviewed annually, and failing to file your income tax return or complete any required renewal steps could result in your payments being reduced or stopped starting in July 2026. Service Canada uses your most recent income information to determine your eligibility and payment amount for the 2026–2027 benefit year. To avoid delays or disruptions to your monthly GIS payments, review the renewal requirements today. Visit the GIS Renewal page for a complete guide and important updates.
