Public health surveillance systems, programs and networks

Conducts lab-based surveillance of antimicrobial resistance in bacterial and fungal pathogens. This surveillance program uses an integrated One Health approach that combines data from humans and animals.

Conducts surveillance activities for blood, tissue, and organ related adverse events in an effort to improve transfusion and transplantation safety.

Monitors Canada's polio-free status by ensuring a sensitive, active surveillance system and prompt, appropriate investigation of acute flaccid paralysis cases to rule out the possibility of poliovirus infection.

Integrates data from 9 PHAC surveillance programs and its partners across human and agricultural sectors to support policy and programming to foster prudent antimicrobial use and to minimize antimicrobial resistance.

Collects data on all residents who are eligible for provincial or territorial health insurance. It can generate national estimates and trends over time for over 20 chronic diseases and conditions, and other selected health outcomes.

Collects and analyzes data on injuries to people who are seen at the emergency rooms of 11 pediatric hospitals and 9 general hospitals in Canada.

Collects, analyzes and communicates trends in antimicrobial use and in antimicrobial resistance for select bacteria from humans, animals and retail meat across Canada.

Conducts timely, ongoing, national monitoring of the circulation of measles, rubella, congenital rubella syndrome (CRS) and congenital rubella infections in Canada.

Collects national epidemiologic and laboratory (molecular and resistance) data on various healthcare-associated infections, antimicrobial resistant organisms and hospital-level antimicrobial utilization.

Collects and studies information about rare childhood diseases and conditions from paediatricians across Canada.

Conducts prospective national surveillance for all types of human prion disease in Canada.

Contributes to a better understanding of antimicrobial-resistant N. gonorrhoeae trends. It does this by linking a subset of antimicrobial-resistant gonorrhea laboratory data to enhanced epidemiologic and clinical data. There are currently 6 participating provinces and territories.

A passive, laboratory-based system monitoring invasive Streptococcus pneumoniae, Streptococcus pyogenes (group A streptococcus, GAS) and neonatal Streptococcus agalactiae (group B streptococcus, GBS).

Monitors the spread of respiratory viruses and influenza-like illnesses year-round, the FluWatch+ surveillance system monitors the progression and severity of respiratory viruses.

Supports activities that will reduce the burden of enteric disease through comprehensive sentinel site surveillance implemented through local public health units and provincial public health laboratories.

A voluntary laboratory-based national surveillance system that monitors antibiotic resistant Neisseria gonorrhoeae. It also monitors resistance trends, characterizes N. gonorrhoeae collected across Canada and supports outbreak investigations.

Routine and enhanced surveillance and estimates of HIV incidence, prevalence and engagement across the HIV care continuum support monitoring of HIV and AIDS in Canada, including progress towards global elimination targets.

Serves as a mechanism for information sharing on summary surveillance indicators of global active public health events affecting humans in the field of emerging respiratory pathogens.

A paediatric hospital-based national active surveillance network for adverse events following immunization, vaccine failures and selected infectious diseases that are, or will be, vaccine preventable.

Monitors infectious diseases in countries with Arctic regions. It does so through a network of hospitals and public health offices in countries with Arctic regions.

Monitors Lyme disease to keep track of the number of human cases of Lyme disease, identify areas where blacklegged and western blacklegged tick populations may be emerging and identify the areas where people are most at risk of Lyme disease.

Conducts public health monitoring of mpox cases reported by provincial and territorial public health authorities on a regular basis, contributing to global monitoring initiatives and watching for the emergence of clade I mpox virus in Canada.

Captures bacteriologic information on invasive meningococcal disease cases for the purpose of describing annual trends, in particular serogroup trends. Enhanced surveillance provides important information for immunization recommendations, vaccine programs and health policies in Canada.

Provides timely analysis and reporting of laboratory confirmed enteric disease cases in Canada. This includes major enteric bacterial pathogens, intestinal parasitic organisms, and enteric viruses.

An interactive website that enables users to explore annual data from the Canadian Notifiable Disease Surveillance System (CNDSS). The CNDSS monitors trends in nationally notifiable diseases, infectious diseases that have been identified collectively by the federal, provincial and territorial governments as priorities for monitoring and control.

Shares data and monitors fatal and non-fatal harms related to opioids and stimulants across the country.

Collects the number of tests and positive detections for 8 respiratory viruses from laboratories across Canada.

Conducts routine and enhanced surveillance of nationally notifiable sexually transmitted and blood-borne infections (STBBI), including chlamydia, gonorrhea, syphilis, hepatitis B, hepatitis C, and HIV and develops population estimates of STBBI incidence, prevalence and engagement in care.

Monitors drug resistance to tuberculosis across Canada by collating information provided from provinces and territories on samples tested for tuberculosis.

Collects community or institutional sewage samples and test them to detect specific diseases or other public health threats. This provides community health data about the levels of disease over time.

Monitors mosquito-borne diseases throughout the year using a One Health approach. Provides the most recent data for humans, mosquito pools, and other animals reported to PHAC.
