Enhanced Surveillance of Antimicrobial-Resistant Gonorrhea System (ESAG): Data representativeness
This page presents how nationally representative the Enhanced Surveillance of Antimicrobial-Resistant Gonorrhea System (ESAG) data are.
- Last updated: 2025-07-04
It describes the proportion of ESAG cases with cultures compared to: i) the total number of gonorrhea cases reported across Canada to the Canadian Notifiable Diseases Surveillance System (CNDSS) and ii) the total number of gonorrhea cultures included in GASP-Canada.

In 2013, PHAC's CCDIC, in partnership with the NML and three provinces (Alberta, Manitoba and Nova Scotia), launched the pilot phase of ESAG. Alberta, which already collected data relevant to AMR-GC, was the first participating jurisdiction. Winnipeg and the Capital District Health Authority in Nova Scotia (now the Nova Scotia Health Authority – Central Zone), began collecting data in 2014. Additionally, in 2018, the Northwest Territories joined ESAG. In June 2023, New Brunswick joined ESAG. Additional provincial and territorial recruitment is ongoing.

Between 2018 and 2023, gonococcal cultures from ESAG cases represented, on average, 23.2% of all N. gonorrhoeae cultures submitted to the NML
Between 2018 and 2022, ESAG cases represented, on average, 2.4% of all gonorrhea cases submitted to CNDSS1. At the time of publication, the most recent CNDSS gonorrhea case data available is from 2022.
