Privacy Policy
Public version · Effective 19 October 2026
This policy expands on our Statement of Information Practices. It describes how Dr. John Stirrat Medicine Professional Corporation (the "practice", "we", "us") collects, uses, discloses, protects and retains personal health information, and how you can exercise your rights under Ontario's Personal Health Information Protection Act, 2004 (PHIPA) and its regulation.
1. Accountability
Dr. John Stirrat is a general surgeon providing consultations, surgery and endoscopy at South Bruce Grey Health Centre and Hanover and District Hospital. He is the health information custodian for the practice under PHIPA and is responsible for the personal health information in the practice's own custody or control. Records a hospital creates while you are its patient (operative reports, anaesthesia and nursing records, hospital test results) are in that hospital's custody; the hospital is a separate custodian with its own privacy office, and requests about those records go to the hospital. The practice keeps the copies it needs in its office chart. As a custodian who is an individual, Dr. Stirrat has not designated a separate contact person and personally carries out the contact-person functions under PHIPA section 15:
- making sure the practice complies with PHIPA;
- making sure everyone who works in the practice knows their privacy duties;
- responding to questions from the public about our information practices;
- responding to requests for access to or correction of records; and
- receiving complaints.
Everyone who works in or for the practice, whether employed, contracted, volunteering or in training, is an agent of the custodian under PHIPA. Agents may only collect, use, disclose, retain or dispose of personal health information as the custodian permits, for the custodian's purposes, and as the law allows. Each agent signs a confidentiality agreement before handling any information and completes privacy training on starting and at least annually.
2. What "personal health information" means
Personal health information is identifying information about you, in any form, that relates to your physical or mental health, the care you have received, payment or eligibility for care, your health card number, your substitute decision-maker, or the donation of body parts or substances. Information that cannot reasonably be used to identify you is not personal health information, and this policy does not restrict our use of properly de-identified information.
3. Purposes of collection, use and disclosure
We collect, use and disclose personal health information for these purposes:
- Providing health care
- Assessing your referral; consultation, informed consent, surgery, endoscopy and procedures; pre-operative and post-operative care and follow-up; prescribing; ordering and receiving tests and pathology; referring you on to other specialists or programs (for example, cancer care or wound care) when needed; and coordinating your care with your family physician or nurse practitioner, the hospital and other providers treating you.
- Communicating with you
- Contacting you about appointments, results, recalls and preventive care, using the contact methods you have agreed to.
- Payment
- Billing OHIP, other insurers, or you for services, and verifying health card eligibility.
- Operating the practice
- Scheduling, record keeping, quality improvement, risk management, training of staff, and planning and evaluating the practice's services.
- Legal and professional obligations
- Meeting mandatory reporting duties, College of Physicians and Surgeons of Ontario (CPSO) requirements, court orders, and audits by OHIP or other authorized bodies.
- Purposes you authorize
- Completing forms and reports for insurers, employers, schools or others at your request.
We limit what we collect to what is reasonably necessary for these purposes. We do not sell personal health information and we do not use it for marketing.
4. How we collect information
We collect information directly from you, or from your substitute decision-maker, whenever that is reasonably possible. We also collect information indirectly, as PHIPA permits, from:
- the family physician, nurse practitioner or other provider who referred you, whose referral usually includes your history, medications and relevant test results;
- hospitals where you are assessed or treated, including operative, pathology and imaging records;
- other health care providers in your circle of care, such as other specialists, pharmacies and home-care agencies;
- laboratories, pathology departments and diagnostic imaging facilities;
- provincial electronic health record systems available to treating clinicians, which may include the Ontario Laboratories Information System (OLIS), the ConnectingOntario ClinicalViewer, and the Digital Health Drug Repository; and
- OHIP, for eligibility and billing purposes.
5. Consent
Implied consent within the circle of care
PHIPA allows health care providers to rely on your implied consent to collect, use and share personal health information for the purpose of providing or assisting in providing you with health care. When another provider refers you to us and you attend, we assume you consent to the sharing of relevant information among the providers involved in your care, including the referring provider, the hospital where your procedure takes place, anaesthesia, pathology and any other specialist we involve, unless you tell us otherwise. This includes information we receive from other providers and information we send to them, such as consultation and operative reports sent back to your family physician.
Express consent
We will ask for your express consent, in writing where practical, before:
- disclosing information to anyone who is not a health care provider treating you, such as an insurer, employer, lawyer, school or researcher;
- disclosing information to a family member or friend who is not your substitute decision-maker;
- using information for any purpose not described in this policy; or
- communicating with you about your care by a method that is not secure, such as unencrypted email or text message.
Capacity and substitute decision-makers
If you are not capable of making decisions about your information, PHIPA sets out who may make them for you, in order of priority. We will record who your substitute decision-maker is and why. A capable person of any age may make their own decisions about their health information; for children under 16, a parent may also make decisions, except about treatment the child has decided on their own or counselling the child has received on their own.
Withdrawing consent
You may withdraw or limit your consent at any time by telling us. Withdrawal is not retroactive: it does not apply to information already collected, used or disclosed. We will tell you if withdrawing consent could affect your care.
6. Lock-box requests
Under PHIPA you may withhold or withdraw consent to the collection, use or disclosure of all or part of your record, including within your circle of care. Common examples are asking that a particular diagnosis not be included in referrals, or that a specific provider not receive your information. When we receive a lock-box request we will:
- discuss with you what the request covers and any risks to your care, so you can make an informed decision;
- record the request in your chart in a way that alerts anyone handling your record;
- apply it to future uses and disclosures, including referrals, reports and electronic sharing, to the extent our systems allow; and
- where we must send information to another provider and your request means something is left out, tell that provider that information has been withheld, without saying what.
A lock-box request does not prevent us from using or disclosing information where PHIPA permits or requires it without consent (section 7 below), including to reduce a significant risk of serious bodily harm.
For referrals we receive about you, you may ask that the referral be handled manually only and not processed with the AI-assisted step described in section 9. We will honour that request for every referral that identifies you once we have recorded it.
7. When we share information without consent
PHIPA permits or requires us to use or disclose personal health information without your consent in limited situations. The ones most likely to arise in a family practice are:
- reporting to public health authorities, including reportable diseases and immunization information required by law;
- mandatory reports, such as suspected child abuse or neglect, a medical condition that may make a person unfit to drive, and reports required under the Regulated Health Professions Act about other health professionals;
- disclosures to the CPSO or another regulatory college for the purpose of its statutory functions;
- contacting a relative, friend or substitute decision-maker if you are injured, incapacitated or ill and unable to give consent;
- reducing or eliminating a significant risk of serious bodily harm to you or someone else;
- complying with a court order, summons, warrant or other legal requirement;
- responding to a legal proceeding in which the practice or the custodian is a party or witness;
- verifying eligibility and billing OHIP, and responding to OHIP audits;
- disclosures to a successor custodian if the practice is transferred or closes, with notice to you; and
- disclosures to a health data institute, prescribed registry or prescribed entity (for example, Ontario Health for cancer registries and screening programs, or surgical quality programs) as PHIPA allows.
8. Service providers and technology we use
We use outside companies to supply information technology and related services. PHIPA calls these electronic service providers. They may only use personal health information as needed to provide the service to us, must keep it confidential, and may not use it for their own purposes. We have written agreements with each of them. Our main providers are:
| Service | Provider | Where information is stored or processed |
|---|---|---|
| Electronic medical record (EMR) | TELUS Health (PS Suite EMR) | Canada (TELUS-hosted) |
| Referral intake and triage software | Operated by the practice on its own computer | Canada (on site) |
| AI-assisted referral triage (see section 9) | Amazon Web Services (Amazon Bedrock) | Request sent to Canada (ca-central-1); processed transiently in the United States; nothing retained |
We do not use any other cloud or AI service to process personal health information. If that changes, we will update this policy and the Statement of Information Practices before doing so.
9. AI-assisted referral triage
What happens
Referrals arrive at the practice mostly by fax. Our triage software reads the fax, extracts the text, and tries to classify the reason for referral and its urgency using rules that run entirely on the practice's own computer. When those rules cannot classify a referral, the software may send the extracted text to an artificial intelligence (AI) language model to obtain a suggested destination, a suggested reason category, and a short explanation.
Before anything is sent
- Only the text of the referral itself is eligible. Nothing else from your chart is sent.
- Cover sheets and duplicate pages are removed.
- A redaction step removes direct identifiers that can be recognized by pattern, including the name block, date of birth (replaced by age in years where clinically relevant), health card number, phone number, address and postal code. Because faxes are imperfect, some identifying details may remain in the free text, and we treat everything sent as if it were identifiable.
- If text extraction or redaction fails for any reason, nothing is sent and the referral is triaged manually.
Where it goes and what the vendor may do with it
- The text is sent over an encrypted connection to Amazon Bedrock, an AI service operated by Amazon Web Services (AWS), at its Canadian endpoint.
- Because no suitable AI model is currently hosted in Canada, AWS processes the request transiently in the United States. This is processing in the United States, not merely transmission through it, and we disclose it for that reason.
- The AWS account is configured for zero data retention: AWS keeps no copy of the request or the response after processing. This setting is locked so it cannot be changed without deliberate administrative action.
- Under its terms of service, AWS does not use customer content to train AI models and does not share it with the company that developed the model (Anthropic).
- AWS's own logging of model requests is turned off. The practice does not log the text sent or the AI's response either.
Human decision-making
The AI's output is only a suggestion. It appears in the triage software clearly marked as unconfirmed. A staff member compares it with the original referral and makes the actual triage decision with the same deliberate action as a manual assignment. The AI cannot move files, write to your record, book appointments or send anything. The practice periodically audits accepted suggestions, not just overridden ones, against the original referrals, and will suspend the feature for any category of referral where it performs poorly.
Records we keep
For each AI suggestion we keep a minimal audit record: the referral identifier, the suggested and the confirmed destination and category, the model used, the reviewer and the time. We do not keep the text sent or the AI's explanation. This audit record is part of your health record and is protected and retained in the same way.
Legal basis
We rely on AWS as an electronic service provider acting on our behalf. Sending a referral to the service to triage it is a use of your information for the purpose for which the referring provider sent it, providing you with health care, and is carried by the implied consent that authorizes the referral itself. We have completed a Privacy Impact Assessment for this use, which is reviewed at least annually and whenever the model, the processing location, the retention settings or the redaction logic change.
Your choice
You may ask for your referrals to be handled manually only. Contact our privacy contact person, or ask your referring provider to write "manual triage only" on the referral. This has no effect on the care you receive or how quickly your referral is handled.
10. Safeguards
We protect personal health information with administrative, technical and physical safeguards appropriate to its sensitivity:
- Administrative
- A designated privacy contact person; written privacy and security policies; confidentiality agreements and annual privacy training for everyone who works in the practice; access to records limited to what each role needs; written agreements with every service provider; a privacy breach procedure; and an annual review of this policy and of our safeguards.
- Technical
- Unique user accounts, strong passwords and multi-factor authentication for the EMR and other systems; encryption of data at rest on practice computers and in transit; audit logs in the EMR of who accessed which record; automatic screen locking; up-to-date operating systems and security software; secure, encrypted backups; and secure channels (such as the EMR's fax integration or provincial systems) for sending information to other providers.
- Physical
- Paper records, computers and fax machines kept in areas not accessible to the public; locked storage for paper records; screens positioned away from public view; and secure shredding of paper and secure wiping or destruction of storage media.
11. Access to your record
You have a right of access to your own personal health record. To request access or a copy:
- Make the request in writing to the privacy contact person. We may ask you to confirm your identity.
- We will respond within 30 days. If we cannot, because the request is large or complex, we will tell you in writing within 30 days and may take up to 30 additional days.
- We may charge a reasonable fee that does not exceed the cost of providing the record. We will give you a fee estimate before proceeding, and you may narrow your request.
- In limited circumstances PHIPA allows or requires us to refuse access to part of a record, for example where it contains information about another person, is subject to legal privilege, or where access could reasonably be expected to result in serious harm. If we refuse, we will tell you the reason, which parts are affected, and that you may complain to the Information and Privacy Commissioner of Ontario.
You may also simply ask your physician to review your record with you at an appointment; no formal request is needed for that.
12. Correction of your record
If you believe your record is inaccurate or incomplete for the purposes for which we use it, you may ask us in writing to correct it. We will respond within 30 days (extendable by up to 30 days with notice) . We will make the correction if you show, to our satisfaction, that the record is incomplete or inaccurate and you give us the information needed to correct it. We are not required to change a professional opinion or observation made in good faith, or a record we did not create and cannot verify.
If we make a correction, we will note the correction in the record so the original entry remains legible, and, at your request, notify anyone we have disclosed the information to in the past year where the correction could affect your care. If we refuse, we will tell you why, and you may require us to attach a concise statement of disagreement to the record, which we will include whenever we disclose that information. You may also complain to the Information and Privacy Commissioner.
13. Retention and disposal
We retain the practice's records in accordance with CPSO requirements: at least ten years from the date of the last entry, or for a patient who was under 18 at the time of the last entry, at least ten years after the patient turns 18. Records may be kept longer where a legal proceeding, audit or investigation is pending.
When records reach the end of their retention period we destroy them securely: paper by cross-cut shredding, and electronic records by deletion from the EMR and secure wiping or destruction of any storage media. We keep a record of what was destroyed, when and how. If the practice closes or transfers, we will give you notice and tell you how to obtain your records.
14. Privacy breaches
A privacy breach occurs when personal health information is stolen, lost, or collected, used or disclosed without authority, including a misdirected fax or an employee looking at a record without a need to. Our breach procedure requires us to:
- Contain the breach immediately, for example by retrieving a misdirected fax, revoking access, or disabling an affected system.
- Notify every affected individual at the first reasonable opportunity, telling them what happened, what information was involved, what we have done, and that they may complain to the Information and Privacy Commissioner of Ontario.
- Report to the Information and Privacy Commissioner of Ontario where PHIPA or its regulation requires (for example, a breach that is part of a pattern, that involves an agent's wilful or snooping access, or that is otherwise significant), and to the CPSO where a regulated professional is involved. We also count all breaches and report the annual statistics to the Commissioner as required.
- Investigate the cause and remediate, including discipline where appropriate and changes to our safeguards.
