The COVID-19 Occupational Risks, Seroprevalence and Immunity among Paramedics (CORSIP) project seeks to identify COVID19-related occupational risks to paramedics and develop recommendations to protect paramedic health


Thank you CORSIP study participants! We are incredibly grateful for the time participants have donated to our study, from which we have acquired valuable information.

The CORSIP study will be ending in early 2023, however we have one final opportunity for participants to provide a blood sample and fill out a *short* questionnaire.

If you have not yet provided all of the samples and questionnaires for the study, please disregard all previous reminders and provide one final sample and fill out one final questionnaire between December 15, 2022 and January 30, 2023. If you have provided all the samples and questionnaires of the study thus far and would be willing to provide an optional final sample and questionnaire, we would welcome your participation as well! This final questionnaire will take around 15 minutes to complete and is much shorter than the previous questionnaires.

Participants, please update your vaccination and COVID-19 infection information on the Participant Portal ( For those of you who have received a bivalent vaccine, please consider providing an extra optional sample 6-8 weeks after the vaccine.

Commercial and hospital lab locations are listed per province on the study website Blood Testing page (, and requisitions are available for download in the Participant Portal ( Mobile Phlebotomy Clinics will be available in January 2023 in British Columbia and Alberta, with specific dates to come.

Please note that samples cannot be accepted after January 30, 2023. This deadline will ensure that we can process and analyze all samples before study end.

Please consider signing the additional consent form in the Participant Portal if you have not already.

We are still welcoming new participants until the end of January 2023.

CORSIP is a study of paramedics in Canada. It aims to recruit 5000 paramedics who will complete surveys and collect blood samples every 6 months.

  • Your blood samples will help us identify how many paramedics have developed antibodies to the virus that causes COVID-19 and how long these antibodies last. These antibodies may be from infection or immunization. Subsequent samples will show if these antibodies are still present. We will share your personal lab results with you through this study portal!
  • Your survey responses will help us assess the occupational risk of working as a paramedic during the COVID-19 pandemic. We will further investigate workplace factors that increase or decrease paramedics' risk of developing COVID-19.

This project is funded by the COVID-19 Immunity Task Force, as part of a national effort to by the Government of Canada to track spread of the virus in priority populations in Canada.
