Using OHS Data for Research

The Ontario Health Study (OHS) is a rich resource for researchers investigating cancer and other chronic diseases. Researchers can now apply for access to de-identified data and biospecimens collected by the Study.

Here's what you need to know about using OHS data for research:

  • Collaboration amongst researchers is strongly encouraged to maximize the access to and use of Study data and biosamples.
  • Access is time-limited and for approved analyses only.
  • Proposals will be accepted for access to:
    • Questionnaire data
    • Physical measures
    • Biorepository materials
  • Only de-identified data and biosamples will be provided to investigators
  • Exclusive access to any data and/or biosamples will not be permitted.
  • Researchers will not receive exclusive access to an analysis or question of interest

Applications will be reviewed by our Data Access Committee who will consider:

  • Scientific merit of the research project
  • Potential impact on research participants
  • Appropriate use of limited resources
