Canadian Antimicrobial ResistanceSurveillance System (CARSS):2025 Key Findings

The 2025 Canadian Antimicrobial Resistance Surveillance System (CARSS) report shows that, while Canada is making progress in integrated, One-Health-based AMR surveillance and stewardship, antimicrobial resistance continues to rise and remains a major public health threat. The report highlights growing concerns around drug-resistant Gram-negative bacteria, sexually transmitted infections—particularly resistant Neisseria gonorrhoeae—and emerging pathogens such as Candida auris. Increasing trends in carbapenemase-producing and ESBL-producing Enterobacterales are noted, and several vulnerable populations (including Indigenous communities, displaced persons, and GBMSM) are disproportionately affected. CARSS concludes that sustained investment, cross-sector collaboration, and strengthened innovation are essential to preserve treatment options, protect at-risk groups, and reinforce Canada’s contribution to global AMR efforts.
