7.1 Professional Misconduct & Incompetence: Rules of Professional Conduct 3.1 to 3.11
Key Takeaways
By-law 20, s. 2.5 lets the RPPC reprimand, suspend or expel a member for professional misconduct (as defined in the By-law, Rules or Code) or for incompetence (as defined in RPPC rules).
Rule 3.1 makes ordinary negligence professional misconduct: failing to maintain the standards a reasonable and prudent practitioner would maintain, with no gross-negligence threshold.
Rule 3.5 makes signing or sealing a final document not actually prepared or checked by the practitioner professional misconduct.
Rule 3.11 (March 2025) requires transparent, ethical and accountable use of AI tools, protecting against bias and ensuring privacy.
One act can lead to OACETT discipline, criminal sanctions, and civil liability, each decided separately.
Professional Misconduct & Incompetence: Rules 3.1 to 3.11
Self-regulation under the OACETT Act, 1998 works only if the association can hold members accountable. The Act lists "to maintain discipline among its members" as one of its objects (s. 2), and By-law 20 supplies the legal hook. For the Practice section of the PPE, you need to know exactly what counts as professional misconduct at OACETT, how it differs from incompetence, and how one careless act can lead to three different kinds of consequence.
1. The Two Grounds for Discipline in By-law 20
By-law 20, s. 2.5 gives the Registration and Professional Practice Committee (RPPC) its discipline power. After notice and an opportunity to be heard, the RPPC "may reprimand, suspend or expel a Member, either absolutely or on condition" for:
| Ground | Where It Is Defined | Core Idea |
|---|---|---|
| (a) Professional misconduct | "as defined in this By-law, the Rules of Professional Conduct or the Code of Ethics" | Conduct that breaches the standards the profession has set, from negligence to dishonesty |
| (b) Incompetence | "as defined in the rules established by RPPC" | A shortfall in the knowledge, skill or judgment needed to practise safely |
Three practical consequences follow:
- Any member can be disciplined. "Member" includes Associate Members as well as Certified Members.
- The Code itself is enforceable. Because misconduct includes breaches of the Code of Ethics, failing to hold public safety paramount (clause (a)) or failing to disclose a conflict (clause (d)) is a disciplinable breach, not just a moral lapse.
- The complaint screen mirrors these grounds. The RPPC Complaints Subcommittee investigates complaints "regarding professional misconduct, incompetence, or a breach of the Code of Ethics." It refuses complaints that do not relate to these grounds, or that are frivolous, vexatious, an abuse of process, or not filed through the documented process.
By-law 20 does not list a separate "incapacity" ground of the kind some health-profession statutes use. If a member's health affects their practice, the questions are still whether the member's conduct fell below the Rules (for example, Rule 3.8 on undertaking work beyond one's competence) or whether the member is incompetent under the RPPC's rules.
2. The Rules of Professional Conduct, Rule by Rule
Section 3 of OACETT's Code of Ethics and Rules of Professional Conduct (updated March 2025) is written "from the point of view of what constitutes professional misconduct." Each rule therefore describes conduct that is misconduct.
Rule 3.1: Negligence
"Negligence, an act or omission in the carrying out of the work of a practitioner that constitutes a failure to maintain the standards that a reasonable and prudent practitioner would maintain in the circumstances."
This is the most important rule to read carefully. It does not require gross negligence, and its wording does not require that anyone was harmed. Ordinary careless work, such as skipping a required calibration or failing to check a calculation a prudent technologist would check, can be professional misconduct even if no loss occurs. Compare tort law (Chapter 1), where a negligence lawsuit fails without actual damage. The disciplinary question is about the practitioner's conduct, not the plaintiff's loss.
Rule 3.2: Safeguarding Life, Health or Property
"Failure to make reasonable provision for the safeguarding of life, health or property of a person who may be affected by the work for which the practitioner is responsible." This rule is the enforceable counterpart of the paramount duty in Code clause (a).
Rule 3.3: Failure to Correct or Report
"Failure to act to correct or report a situation that the practitioner believes may endanger the safety or the welfare of the public." Silence is misconduct. Together with Code clause (i), this rule is the basis of the duty to report.
Rule 3.4: Compliance With Laws and Codes
"Failure to make responsible provision for complying with applicable statutes, regulations, standards, codes, by-laws and rules in connection with work being undertaken by or under the responsibility of the practitioner." It covers work done by others under your responsibility, such as a field crew you supervise.
Rule 3.5: Signing or Sealing Unchecked Work
"Signing or sealing a final drawing, specification, plan, report or other document not actually prepared or checked by the practitioner." The test is simple: if you neither prepared it nor checked it, you may not sign or seal it. Applying the OACETT member identification stamp to a subcontractor's drawings you have not checked ("rubber stamping") is a classic breach.
Rule 3.6: Overruled Judgement
"Failure of a practitioner to present clearly to his/her employer the consequences to be expected from a deviation proposed in work, if the judgement of the practitioner is overruled by non-technical authority in cases where the practitioner is responsible for the technical adequacy of the work." It enforces Code clause (h).
Rule 3.7: Breach of the Act or By-law
"A breach of the Act or By-law, other than an action that is solely a breach of the Code of Ethics, or the Rules of Professional Conduct." Example: using a protected designation you are not registered to use, contrary to section 11 of the Act.
Rule 3.8: Work Beyond Competence
"Undertaking work the practitioner is not competent to perform by virtue of his/her training and experience." This enforces Code clause (b). Note the difference from the incompetence ground. Rule 3.8 punishes accepting work outside your competence; incompetence concerns a general inability to practise to standard.
Rule 3.9: Undisclosed Conflicts of Interest
Failure to make "prompt, voluntary and complete disclosure of an interest, direct or indirect, that might in any way be, or be construed as, prejudicial to the professional judgement of the practitioner." The rule lists five acts that require prior disclosure (see Section 5.2).
Rule 3.10: Disgraceful, Dishonourable or Unprofessional Conduct
"Conduct or an act relevant to the practice of engineering technology that, having regard to all the circumstances, would reasonably be regarded by technology professionals as disgraceful, dishonourable or unprofessional." This catch-all is judged by the standards of the profession and covers dishonesty such as falsified test logs, fabricated references, or harassment of colleagues.
Rule 3.11: Artificial Intelligence (Added March 2025)
"Members must ensure Artificial Intelligence (AI) tools are being used in a transparent, ethical, and responsible manner, staying accountable for their results, protecting against bias, ensuring privacy, and committing to ongoing competency in AI technologies, while meeting the same expectations with respect to safety of the public."
| AI Practice | Rule 3.11 Concern |
|---|---|
| Pasting a client's confidential specifications into a public chatbot | Privacy and confidentiality (also Code clause (d)) |
| Issuing an AI-generated load or flow calculation without checking it | Accountability for results; Rules 3.1 and 3.5 |
| Hiding from the client that a report section was drafted by an AI tool when that matters to how it is relied on | Transparency |
| Using an AI screening tool that systematically mis-scores certain contractors | Protecting against bias |
| Adopting a new AI design assistant without learning its limits | Ongoing competency |
3. Misconduct vs. Incompetence at a Glance
| Dimension | Professional Misconduct | Incompetence |
|---|---|---|
| Source of definition | By-law 20, the Rules of Professional Conduct (3.1 to 3.11), and the Code of Ethics (clauses (a) to (k)) | Rules established by the RPPC |
| Typical evidence | A specific act or omission, such as an unchecked seal, an undisclosed interest, or ignoring a hazard | A pattern showing the member lacks the knowledge, skill or judgment to practise safely |
| Example | Signing a report you did not check (Rule 3.5) | Repeated fundamental errors across projects despite supervision |
| Overlap | Accepting work beyond your competence is misconduct under Rule 3.8 | Being unable to do work within your designation is incompetence |
| Available outcomes | Reprimand, suspension, expulsion or conditions (By-law 2.5), with the remedies in the Discipline Subcommittee Terms of Reference | The same powers, often used to impose remedial conditions such as courses or supervision |
4. One Act, Three Kinds of Consequence
The PPE study materials stress that professional liability can lead to three separate consequences, and the same incident can trigger all three:
- Discipline proceedings by OACETT under By-law 20 and the Rules. These protect the public and the profession, and can end in a reprimand, conditions, a fine, suspension or expulsion.
- Criminal sanctions where the conduct is also a crime. Examples are criminal negligence causing death or bodily harm, fraud, or breach of the duty in section 217.1 of the Criminal Code (the Westray amendment) to take reasonable steps to prevent bodily harm to people one directs at work. Regulatory prosecutions under the OHSA or EPA are a related track.
- Civil action by an injured client or third party, usually in negligence or for breach of contract, seeking compensation (Chapter 1).
Each track has its own decision-maker and standard of proof. A member acquitted in criminal court can still be disciplined, and a member who wins a civil suit can still be found to have breached Rule 3.5.
A Certified Engineering Technologist (C.E.T.) is assigned to calculate storm water runoff retention volumes for a new commercial subdivision. Despite an accredited diploma, the technologist repeatedly misapplies basic hydrologic equations, produces basin sizes that are wrong by an order of magnitude, and keeps failing to apply fundamental principles despite employer tutoring. Which discipline ground in By-law 20 best fits?
Professional misconduct under Rule 3.5, since every calculation error counts as signing unchecked work
Incompetence: a persistent lack of the knowledge, skill or judgment needed to practise safely
A breach of the OACETT Act under Rule 3.7, since the Act itself sets hydrologic design standards
None, because By-law 20 covers only dishonesty and conflicts of interest
A certified member applies their OACETT member identification stamp to structural shop drawings prepared by an outside drafting firm, without checking them or supervising their preparation. Which rule does this breach?
Rule 3.9, because accepting any outside drawings creates a conflict of interest that must be disclosed
No rule, provided the drafting firm agreed in writing to accept full responsibility for the drawings
Rule 3.5, on signing or sealing a final document not actually prepared or checked by the practitioner
Rule 3.11, because all drafting firms now use artificial intelligence tools to prepare shop drawings
Under Rule 3.11, added to OACETT's Rules of Professional Conduct in March 2025, which practice best meets a member's obligations when using artificial intelligence (AI) tools?
Checking AI output, owning the results, protecting privacy, and being open about AI use
Issuing AI-generated calculations unreviewed, since the vendor answers for accuracy
Uploading confidential client specifications to a public AI chatbot for speed
Avoiding AI entirely, because Rule 3.11 prohibits its use in the profession
