TCPS 2 Chapter 7 (Conflicts of Interest)

Chapter 7 of Canada’s Tri-Council Policy Statement: Ethical Conduct for Research Involving Humans (TCPS 2) sets out how researchers, Research Ethics Boards (REBs) and institutions must identify, disclose and manage conflicts of interest that arise in connection with human-participant research. TCPS 2 is the joint policy of Canada’s three federal research agencies (CIHR, NSERC and SSHRC), and REB review under it is required wherever Article 2.1’s REB review trigger applies.

Why Chapter 7 treats conflict of interest as a distinct concern

TCPS 2’s core principles — respect for persons, concern for welfare, and justice — depend on researchers, REBs and institutions being able to act in participants’ interests without divided loyalties. Chapter 7 frames conflict of interest as a threat to that independence: a competing interest can distract attention from participant welfare and from the integrity of the research record, even when no one involved intends any wrongdoing. For that reason, the chapter’s threshold for what must be disclosed is deliberately broad — covering real, potential and perceived conflicts alike, on the reasoning that a plausible appearance of compromised judgment is itself corrosive to trust in the research, independent of what actually happened.

Three levels of conflict of interest under Chapter 7

Individual conflicts of interest

An individual conflict arises when a researcher’s own personal, financial, professional or other interest could compromise, or appear to compromise, their judgment in designing, conducting, reporting or overseeing a study. Common triggers include equity or consulting ties to a study sponsor, royalties or licensing income tied to a product under study, and personal or supervisory relationships with participants or trainees involved in the research.

Institutional conflicts of interest

An institutional conflict exists when the institution itself — rather than any one researcher — has a financial or other stake in a study’s outcome (for example, an equity interest in a sponsoring company, or a significant funding or licensing relationship). Chapter 7 treats this as a distinct category from individual COI because managing it may require review arrangements that route around the institution’s own normal channels, since an REB operating under the same institution cannot fully insulate itself from an institutional-level interest.

REB-member conflicts of interest

Because REBs are the body responsible for identifying and managing everyone else’s conflicts, Chapter 7 also governs conflicts held by the reviewers themselves. Where an REB member has a personal, professional or financial connection to a protocol under that board’s review — as the investigator, a close collaborator, a supervisor or supervisee, or a person with a financial stake in the outcome — the member must disclose the connection and recuse from deliberating on and deciding that protocol. This sits alongside the REB composition and governance requirements in TCPS 2 Chapter 6, which sets minimum board membership; Chapter 7 is what removes a specific member from a specific decision when their independence on that file is compromised.

Managing a conflict once identified

Chapter 7’s stated preference is prevention: avoiding a conflict of interest in the first place is preferable to managing one after the fact. Where a conflict cannot be avoided, it must be disclosed to the appropriate parties — the REB, the institution, and, where the conflict is relevant to a person’s willingness to participate, prospective participants themselves — and steps must be taken to minimize or manage it. In some cases the conflict cannot be adequately managed short of the researcher, REB member or institution stepping back from one of the competing interests entirely.

Disclosure to research participants

Where a conflict of interest is material to a prospective participant’s decision to take part, TCPS 2 directs that it be disclosed as part of the free and informed consent process under Chapter 3 / Article 3.1 — and, consistent with Chapter 7’s real/potential/perceived framing, disclosure is expected for conflicts in any of those three categories, not only for a conflict that has demonstrably affected the study.

How this differs from US human-subjects COI rules

TCPS 2 Chapter 7 is the Canadian counterpart to the individual and institutional financial-conflict rules that apply to US federally funded human-subjects research, but the two frameworks are structured differently. In the US, individual financial conflicts are chiefly governed by the NIH Financial Conflict of Interest (FCOI) policy and related agency-wide significant-financial-interest disclosure and management-plan requirements, reviewed alongside — but procedurally distinct from — IRB approval of the protocol itself. TCPS 2 folds conflict-of-interest review directly into the REB’s own function rather than routing it through a separate federal FCOI compliance process, and explicitly extends the obligation to REB members’ own conflicts as part of the same chapter — a governance detail that isn’t a comparably central, named feature of the US framework. See the general Conflict of Interest (COI) in Research and Appearance of a Conflict of Interest terms for the underlying concepts that both national frameworks are built on.

Frequently asked questions

What counts as a conflict of interest under TCPS 2 Chapter 7?

Any personal, financial, professional or institutional interest that could compromise, or reasonably appear to compromise, a researcher’s, REB member’s or institution’s duty toward research participants or the integrity of the research — assessed at the individual, institutional and REB-member level separately.

Does TCPS 2 Chapter 7 require REB members to recuse themselves?

Yes. Where a board member has a personal, professional or financial connection to a protocol under review — for example, as the investigator, a close collaborator, or a person with a financial stake in the outcome — Chapter 7 requires disclosure of the connection and recusal from that protocol’s deliberation and decision.

Does a perceived conflict of interest need to be disclosed even if it didn’t affect the research?

Yes. Chapter 7 treats real, potential and perceived conflicts as equally disclosable; a reasonable appearance of compromised judgment is itself the concern, independent of whether the conflict demonstrably influenced any decision.

How is this different from US IRB conflict-of-interest rules?

The US framework centers on agency-specific financial conflict of interest (FCOI) policy and significant-financial-interest disclosure, reviewed alongside IRB approval; TCPS 2 Chapter 7 builds conflict-of-interest review directly into the REB’s function and explicitly covers REB members’ own conflicts within the same chapter.
