Research ethics The policies and practices governing the ethical conduct of research in Canada are established by the Tri-Council Policy Statement: Ethical Conduct for Research Involving Humans, 2nd edition (TCPS-2). Researchers are expected to be familiar with the TCPS-2 requirements on research ethics. To learn more about TCPS-2 please access the on-line tutorial Introductory tutorial for the Tri-Council Policy Statement: Ethical Conduct for Research Involving Humans (TCPS). All research involving human subjects conducted at, or under the auspices of, Durham College follows Tri-Council guidelines and requires ethics review and approval by a Research Ethics Board (REB) prior to commencing the research. This includes work by Durham faculty, staff and students and researchers external to the College who intend to conduct research at Durham College.
