Provinces and Territories participating in AMRNet
The Public Health Agency of Canada's AMRNet program collects antimicrobial resistance data submitted by laboratories from provinces and territories across Canada. Currently results include data submitted by laboratories in British Columbia, Alberta, Saskatchewan, Ontario, New Brunswick, Newfoundland and Labrador, Northwest Territories and Prince Edward Island.

Map text description
AMRNet currently includes data submitted by laboratories in British Columbia, Alberta, Saskatchewan, Ontario, New Brunswick, Newfoundland and Labrador, Northwest Territories and Prince Edward Island. Yukon, Nunavut, Manitoba, Quebec and Nova Scotia are shown as not currently participating.
Antimicrobial Resistance (AMR) data
The figures and tables below summarize antimicrobial resistance trends among clinical isolates from blood and urine. These data can be further refined by year and case type (All, Inpatient and Outpatient/Community). Please see the Methods and limitations section below for a detailed description of the data included in these charts.

Methods and limitations
AMRNet is a national surveillance program that collects phenotypic susceptibility data on clinical isolates from both inpatient and outpatient/community settings, including long-term care.
Data from participating laboratories may not be representative of all Canadian regions. Different laboratories use different techniques for antimicrobial susceptibility testing. Data on specific bacteria-antimicrobial combinations are not available from all laboratories.
As testing practices may vary across settings and some isolates are submitted without an identified setting, stratified data (inpatient, outpatient/community) may not always correspond to the same isolates as the overall results. As such, differences between stratified and overall totals may occur and results should be interpreted with caution. Additionally, different setting categories may reflect different jurisdictions, in accordance with the AMRNet reporting criteria outlined below.
To reduce the likelihood of bias in results, AMRNet uses the following reporting criteria for antibiograms:
- Data must represent laboratory-bacteria-specimen type combinations where at least 85% of isolates are tested or reported for a given antimicrobial.
- Data must represent isolates from at least three provinces/territories.
- Data must represent at least 30 isolates.
Fields that do not meet these requirements are blank under Percent susceptibility in the text description for Figure 2.
Where possible, duplicates, as defined by the Clinical & Laboratory Standards Institute, were removed for all analyses presented here.
