Complaints and Investigations

Complaint or Registrar’s Investigation: Why the Difference Matters

Two matters can look identical from the outside and follow different rules. Knowing which one you are in helps you understand who is involved, how long it may take, and what you can challenge afterward.

Key Takeaways

  • A complainant is a party who receives the decision. A reporter usually is not, and is generally not told the outcome.
  • In the health professions, HPARB review rights are tied to complaints (Code, s. 29).
  • The same committee usually decides both, with the same range of outcomes.
  • Registrar’s investigations often start with mandatory reports from employers.

Two Routes Into the Same Committee

Under the Health Professions Procedural Code, a panel of the Inquiries, Complaints and Reports Committee considers both complaints and reports following a registrar’s investigation (Code, s. 25(1)). The Registrar may appoint investigators where there are reasonable and probable grounds to believe a member has committed misconduct or is incompetent, with the committee’s approval, or in an emergency without it (s. 75). Other statutes have similar structures. Social workers’ complaints go to the Complaints Committee, while the Registrar directs investigations and reports results to the committee the Registrar considers appropriate (SWSSW Act, ss. 24, 32, 35).

What Changes Depending on the Route

IssueComplaintRegistrar’s investigation or report
Who started itA complainant, often a patient or clientThe regulator, often after an employer or other mandatory report
Is the source a party?Yes; receives the decisionGenerally no; usually not told the result
Expected timeline (health)150 days, with notice if missed (Code, s. 28)No equivalent statutory target
HPARB review (health)Available to both sides, with exceptions (Code, s. 29)Generally not available
Your duty to co-operateWritten submissions are optional but advisable (Code, s. 25.2)Must co-operate fully with investigators (Code, s. 76(3.1))

CRPO, for example, tells the public that reports have no set timeline and no opportunity to request an HPARB review, and that the committee’s outcomes are the same for complaints and reports.

Practical Consequences

If your matter is a complaint, expect your response to be shared with the complainant, and expect that either side may seek a review. If it is a registrar’s investigation, expect broader information gathering, interviews with employers and witnesses, and fewer opportunities to challenge the committee’s decision afterward. In both, your written submissions are often the most important document you will produce.

Frequently Asked Questions

Can a complaint turn into a registrar’s investigation?

Information from a complaint can lead the Registrar to investigate more broadly. Check each notice you receive for the type of matter it describes.

Does the route change the possible penalty?

Generally not. The committee’s range of outcomes, from no action to a referral to discipline, is the same (e.g. Code, s. 26).
