About CORR

  • What is the Canadian Organ Replacement Register?
    The Canadian Organ Replacement Register (CORR) is a pan-Canadian database managed by the Canadian Institute for Health Information (CIHI). CORR’s mandate is to record and analyze the level of activity and outcomes of vital organ transplantation and renal dialysis activities.
  • Who is responsible for this database?
    CIHI manages this register.
  • What is the value of this database?
    This pan-Canadian database provides statistics that track long-term trends for organ transplantation, organ donation, waiting list statistics and dialysis activity. In doing so, the database makes comparative data available that can contribute to better treatment and patient care, and enhance research.

Organ transplants

  • How many dialysis centres are there in Canada?
    The most recent information available from CORR reported a total of 75 hospital-based programs in Canada (excluding Quebec) in 2018 that offered full-care renal services.

Organ donors

  • How many organ donors are there?
    In 2018, there were 761 deceased organ donors. In addition, there were 555 living donors.
  • How are organ donations from deceased and living organ donors different?
    A living donor provides a single organ for transplant, but a deceased organ donor can provide up to 8 organs. In addition, living donors are often related to the recipient, while this is not necessarily the case for deceased organ donors.
  • How can someone become an organ donor?
