To describe trends in the prevalence of healthcare-associated infections (HAIs) and antibiotic-resistant organisms (AROs) in Canadian acute-care hospitals. Repeated point prevalence surveys. Canadian Nosocomial Infection Surveillance Program (CNISP) hospitals. Trained infection control professionals reviewed medical records of eligible adult patients and applied standardized definitions to collect demographic data and information on HAIs, AROs, and additional precautions from 39 to 62 hospitals in 2002, 2009, 2017, and 2024. The prevalence of adult patients with at least one HAI increased from 10. 4% (95% CI: 9. 6%-11. 2%) in 2002 to 12. 4% (95% CI: 11. 7%-13. 2%) in 2009, declined to 8. 4% (95% CI: 7. 8%-9. 0%) in 2017, and stabilized in 2024 (8. 1%, 95% CI: 7. 6%-8. 6%) despite 3. 1% of HAIs being due to SARS-CoV-2. Between 2017 and 2024, there were increases in bloodstream infections (1. 0% to 1. 5%, p = 0. 002), viral respiratory infections (VRI) (0. 3% to 0. 6%, p
