The purpose of the Biobank is to accelerate future research projects and build health monitoring opportunities on a nationally-representative sample of Canadians. The Biobank receives samples from surveys like CHMS or CCAHS that collect dried blood spot, blood, urine, and saliva samples from consenting participants. These samples are stored in a secure location for future health studies. To obtain approval for the use of these samples, research projects undergo a thorough scientific, ethical, and security review process.
