The Criminal Justice Relational Database (CJRD) was created to allow multivariate analyses on the demographic and socioeconomic factors associated with (repeated) criminal justice system involvement in Canada. It consists of anonymized, integrated criminal justice data, as well as other integrated social data sources (e.g., economic, health, and education data). Integrated files refer to microdata files that are equipped with unique anonymous identifiers that allow the merging of variables at the person level between files. 

New CJRD data linked to hospitalization, education, census, tax data, CVSD and IMDB is now available in Research Data Centres across Canada.

The CJRD has produced new cohort and concordance files and updated concordance files:

Cohort files: 

  • ICCS  2022/2023

  • CCSS 2022/2023

Concordance files[[1] To use these concordance files, researchers are to request access to (1) Cohort files (e.g. ICCS Allyears), (2) concordance file (e.g. CJRD-Education) and (3) Additional corresponding data source(s) (e.g. PSIS Allyears). 1] : 

  • CJRD linked to hospitalization data

    • ICCS 2022/2023 and CCSS 2022/2023 – DAD 2022/2023, NACRS 2022/2023 and 2023/2024, OMHRS 2022/2023

  • CJRD linked to education data

    • ICCS 2022/2023 and CCSS 2022/2023 – PSIS, RAIS 2021 - 2023

  • CJRD linked to Census data

    • ICCS 2022/2023 and CCSS 2022/2023 - Census - 2006, 2016, 2021 NHS – 2011

  • CJRD linked to tax data

    • ICCS 2022/2023 and CCSS 2022/2023 - T1FF 2022

  • CJRD linked to CVSD

    • ICCS 2022/2023 and CCSS 2022/2023 – CVSD 2021 – 2023

  • CJRD linked to IMDB

    • ICCS 2022/2023 and CCSS 2022/2023 – IMDB 2021

 

The datasets have been expanded to include additional years: 

  • Integrated Criminal Court Survey (ICCS): 2021/2022 and 2022/2023

  • Canadian Correctional Services Survey (CCSS): 2022/2023

  • T1 Family File (T1FF): 2022 

  • National Ambulatory Care Reporting System (NACRS): 2022/2023 and 2023/2024 

  • Discharge Abstract Database (DAD): 2022/2023

  • Ontario Mental Health Reporting System (OMHRS): 2022/2023

  • Post-secondary Student Information System (PSIS): 2021, 2022 and 2023

  • Registered Apprenticeship Information System (RAIS): 2021, 2022 and 2023

  • Vital Statistics Death Database (CVSD): 2021, 2022 and 2023 

 

A correction to the CCSS custody dates file was applied. Missing custody events from Saskatchewan were added to the file for fiscal years 2015/2016 and 2016/2017. Custody data from all jurisdictions were also reprocessed which resulted in small changes in the number of records across all years of data in the CCSS custody dates file.  

Longitudinal Immigration Database (IMDB) and Census 2021 data have been incorporated into the CJRD.

 Uniform Crime Reporting Survey (UCR) information has been added to the user guide, and the corresponding data is expected to be available in winter 2026.
