ERLF (Extending the Relevance of the Longitudinal Files)


Longitudinal data allow researchers to be able to better understand the factors behind events or problems. Given the importance of longitudinal data in research, it was important to find a way to extend the usefulness of Statistics Canada’s longitudinal data for research purposes.
The outcome files contain only the survey identifier and the specific file’s outcome variables that were approved for this linkage project. Users will need to merge the survey file with these outcome files to build a linked analysis file for their analytical purposes and instructions for merging files is provided in the user guide.


Description of Administrative Datasets:

T1 Family File (1993-latest available): The T1 is the personal tax return filled out each year by Canadians. This data allows users to see the tax data for the family as opposed to ungrouped individuals. The “family” is defined as a census family: the census family data include parent(s) and children (i.e., children who do not live with their spouse or partner and do not have children of their own) living in the same dwelling.  The individual T1 file is combined with the T4 tax file and the Canada Child Tax Benefit (CCTB) file. More details can be found at the StatCan website.


Canadian Vital Statistics Death Database (1993-latest available): This file contains demographic and cause of death information for all decedents. Specifically, the following information is available:

  • Age, sex, marital status, place of residence and birthplace of the deceased
  • Date of death
  • Underlying cause of death classified to the " World Health Organization International Statistical Classification of Disease and Related Health Problems" (ICD)
  • Province or territory of occurrence of death
  • Place of accident (for most non-transport accidental deaths)
  • Autopsy (whether one was held, and if so, whether the results of it were taken into account in establishing the cause of death)

Further information regarding the death database is available.


Canadian Cancer Registry (1992-latest available): The Canadian Cancer Registry contains comprehensive data on all tumours recorded in a patient over time. Diagnostic codes and basic demographic information (sex, age) are available in addition to numerous details about all recorded cancers. Full details regarding the cancer registry is available.
