Preface

In Canada, most facilities where human pathogens are handled and stored are regulated by the Public Health Agency of Canada (PHAC) under the Human Pathogens and Toxins Act (HPTA) and the Human Pathogens and Toxins Regulations (HPTR). The HPTA and HPTR set out reporting and notification requirements for licence holders, biological safety officers, and persons conducting controlled activities authorized under a Pathogen and Toxin Licence. The Canadian Biosafety Standard (CBS) sets out additional operational practice requirements for notification and reporting, detailing the specific timelines, reporting forms, and reporting processes. The Notification and Reporting under the HPTA and HPTR Using the Reporting Module of the Biosecurity Portal guideline (Guideline) serves as a resource for stakeholders, providing more in depth information and guidance on how to complete and submit a notification and subsequent follow-up report.

This Guideline was developed by the PHAC as part of an ongoing series of biosafety and biosecurity themed guidance documents. It is a continuously evolving document and subject to ongoing improvement. The PHAC welcomes comments, clarifications, and suggestions for incorporation into the future versions of the Guideline. To this end, please send information with references (where applicable) for continual improvement of this Guideline to:

Chapter 1 – Introduction

The words in bold type are defined in the glossary found in Chapter 4.

In Canada, all facilities where human pathogens or toxins are handled or stored are regulated under the Human Pathogens and Toxins Act (HPTA) and the Human Pathogens and Toxins Regulations (HPTR).Footnote 1,Footnote 2 The Public Health Agency of Canada (PHAC) has the ultimate authority to implement provisions of the HPTA and HPTR.

The HPTR came into force on December 1, 2015. At the same time, the remaining sections of the HPTA also came into force and the Human Pathogens Importation Regulations were repealed. The Canadian Biosafety Standard (CBS) sets out additional operational practice requirements for notification and reporting, detailing the specific timelines, reporting forms, and reporting processes.Footnote 3 The Canadian Biosafety Handbook (CBH) provides additional guidance that supports the HPTA, the HPTR and the CBS.Footnote 4 The Notification and Reporting under the HPTA and HPTR Using the Reporting Module of the Biosecurity Portal guideline (Guideline) provides more in depth information and guidance on the notification, investigation, and reporting requirements set forth in the HPTA, HPTR, and CBS.

Section 16 of the HPTA specifies that no information provided under Sections 12 to 15 of the Act, by a licence holder or a person conducting activities under the authority of a Pathogen and Toxin Licence issued by the PHAC, may be used or received against that person in any criminal proceedings that are subsequently instituted against them, other than with respect to a contravention of Section 17 of the Act.

This guideline also contains a comprehensive glossary of definitions for technical terms, located in Chapter 4; words defined in the glossary appear in bold type upon first use. The appendices provide additional information related to notification and reporting, including guidance on incident investigation and step by step instructions for the completion and submission of exposure notification and exposure follow-up reports using the Biosecurity Portal.

1.1 Scope

This Guideline provides comprehensive guidance on how to complete and submit a notification report and, where exposure or laboratory acquired infections/intoxications (LAIs) is concerned, a subsequent follow-up report to the PHAC in accordance with requirements in the HPTA, HPTR and CBS.

Situations which require mandatory notification, as specified in the HPTA and HPTR, can generally be grouped into four categories: laboratory incidents, changes requiring issuance of a new licence, changes that may require an amendment or revocation of an existing Human Pathogens and Toxins Act Security Clearance (HPTA Security Clearance), and other events requiring notification.

This document provides detailed guidance on notification and reporting procedures pertaining to laboratory incidents and other events requiring notification.

Laboratory incidents include:

Other events requiring notification include:

1.2 Obligation to inform the Minister

In practice, the obligation to inform the Minister under the HPTA and/or the HPTR means providing information to the PHAC via the submission of a notification and/or follow-up report, as stipulated for the type of event and circumstances described below. Additional communication and reporting may be required on a case-by-case basis, where necessary.

The obligation to inform the PHAC of events is linked to either the licence holder or the biological safety officer (BSO). It is expected that licence holders may delegate their reporting role to the BSO; however, licence holders remain ultimately responsible for certain reporting under the HPTA.

1.3 Notification and Reporting Process

1.3.1 Biosecurity Portal

The PHAC online Biosecurity Portal (the Portal) facilitates notification and/or detailed reporting in accordance with the HPTA, HPTR, and the respective operational practice requirements specified in the CBS. Whenever possible, the laboratory incident and other reports specified in Section 1.1 should be reported through the Portal's reporting module.

1.3.1.1 Tips for using the Biosecurity Portal

Important Tips for Preparing and Submitting Reports through the Biosecurity Portal:
Tip Description
Save early and often! At each data entry page, always save the information that you have entered before navigating to another page. Not saving could result in the loss of the information that you have entered.
For the exposure follow-up report, the mandatory biological agent fields do not appear until the affected person record is saved. If these biological agent fields are not completed the report cannot be submitted. The system will indicate that fields in the Administrative Information section of the report have not been completed. If all visible mandatory fields on this page have been completed, open each affected person(s) record on this page and ensure that the biological agent fields have been completed.
Answer all questions displayed on the form whenever the information is relevant and available Complete all fields if the information is available whether the field is marked mandatory (*) or not.
Do not include sensitive personal information.

Do not provide names or any sensitive personal information about any affected persons in the report.

Do not include names or any sensitive personal information about any holder of a HPTA Security Clearance who has been prohibited access to a facility. This information will be collected after the initial notification report is submitted, when the reporter is contacted by a representative from the Centre for Biosecurity.
Submit only one report type for a single incident

If your notification involves an exposure or infection/intoxication of one or more individuals in the laboratory/facility setting, report the incident as an exposure/LAI.

If the incident also involves another incident type, clearly indicate this (e.g., inadvertent possession, missing pathogen) within the exposure report notes.
Electronic completion and submission of an exposure notification report Some information will be prepopulated when completing a report based on the user profile of the individual making the report (e.g., licence number and reporter name).
Description of the event

The notification report includes a text box for submitting a description of the event.

Provide sufficient details of the event so that representatives from PHAC can assess the situation and act accordingly.
If you have any questions about reporting or need assistance, contact the PHAC at pathogens.pathogenes@phac-aspc.gc.ca or 1-613-957-1779.

1.3.2 Other Methods of Reporting

In the event the Biosecurity Portal is unavailable (or for voluntary reporting) licence holder representatives and BSOs are asked to contact the PHAC for assistance:

Chapter 2 – Notification Reports

Note: If your notification involves an exposure or infection/intoxication of one or more individuals in the laboratory/facility setting, report the incident as an exposure or LAI. If the incident also involves another incident type, clearly indicate this (e.g., inadvertent possession, missing pathogen) within the exposure report "Additional notes" Section A.2.6 at the end of the report. There is no need to submit more than one report type for a single incident as indicated in subsection 1.3.1.1.

2.1 Laboratory Incidents

2.1.1 Exposures and Laboratory Acquired Infections/Intoxications

A licence holder must inform the PHAC without delay if they have reason to believe an incident involving a human pathogen or toxin in the licence holder's possession has or may have caused disease in an individual. Notification without delay provides a timely alert (i.e., as soon as reasonably possible) and permits time for immediate response and control measures to be taken.

The CBS sets out the minimum operational practice requirements for licence holders to meet the HPTA reporting obligations, detailing the specific timelines, reporting forms, and reporting processes.

In particular, incidents involving exposure to a human pathogen or toxin or an LAI require submission of the following as per the CBS:

  1. an exposure notification report to be submitted without delay, (i.e., as soon as reasonably possible); followed by
  2. an exposure follow-up report, documenting the results of the investigation as known, to be submitted within the prescribed timelines.

See Appendix A for detailed guidance on how to complete the exposure notification report using the Portal.

2.1.1.1 Exposure Assessment

The determination of whether or not an incident involves exposure of one or more individuals is based on a facility's assessment of the incident, which should consider all relevant facts and circumstances to ultimately assess whether or not an inhalation, ingestion, inoculation, or absorption has, or may have, occurred.

Figure 2-1 illustrates a decision chart to assist in the exposure assessment.

Figure 2-1: Decision Chart to Assist in the Assessment of an Incident to Determine if an Exposure has Occurred and if Notification of the Public Health Agency of Canada (PHAC) is Required.Footnote 4 Figure 2-1 note *

Decision Chart to Assist in the Assessment of an Incident to Determine if an Exposure has Occurred and if Notification of the Public Health Agency of Canada (PHAC) is Required. Text description follows.
Figure 2-1 - Text description

Figure 2-1: Decision chart to assist in the assessment of an incident to determine if an exposure has occurred and if notification of the Public Health Agency of Canada (PHAC) is required.

If an incident involved an RG2, RG3, or RG4 pathogen or toxin, and there is reason to believe that the incident involved one or more individuals' contact with, or close proximity to, infectious material or toxins that may result in infection or intoxication then an exposure occurred. Contact or close proximity is defined as possible exposure via inhalation, ingestion, inoculation, or absorption. If an exposure has occurred, an exposure notification report is to be prepared and submitted without delay, and an exposure follow-up report submitted within 30 days, or in the case of an SSBA, within 15 days.

If the incident did not involve an RG2, RG3, or RG4 human pathogen or toxin, or if there is no reason to believe that contact or close proximity with pathogens or toxins may have resulted in infection or intoxication, then best practice dictates that the incident be documented internally within the facility in the event that the information is needed for recall or reassessment at a later date.

If a disease is detected and there is reason to believe that it may be linked to an exposure in the containment zone setting, then it is classified as an LAI and a previously missed or unreported exposure. In such a case, an exposure notification report and follow-up report are to be prepared and submitted as described above. If there is no reason to believe that the disease may be linked to the containment zone, then exposure is ruled out and there is no further action required.

In most cases, a disease state will include recognition of an illness, syndrome, or known disease. However, some facilities may employ medical surveillance practices that could identify a seroconversion, which may provide an additional source of information for recognition of infection or disease states.

Even if exposure/LAI is ruled out, documenting the details of the incident/disease and investigation findings within the facility's records is required in accordance with the re-examination at a later time, if necessary.

Additional guidance on assessing whether an exposure requiring notification of the PHAC has occurred and on conducting an incident investigation is available in the Appendix B of this document and Chapter 18 of the CBH.

2.1.2 Inadvertent Possession, Production or Release

Incidents involving inadvertent release, inadvertent production, or inadvertent possession of a human pathogen or toxin require a notification to the PHAC and will be followed up on a case by case basis where additional information may be required.

If a licence holder has reason to believe that a human pathogen or toxin has been released inadvertently from the facility in the course of an activity that is otherwise authorized by the licence, the licence holder shall, without delay, inform the Minister of the release [HPTA 12(1)].

The notification report provides the PHAC with a description of the event, which should include the following information:

2.1.3 Missing, Stolen or Lost Human Pathogen or Toxin, including when a Security Sensitive Biological Agent (SSBA) is not received within 24 hours of the expected date and time of receipt

Incidents involving a missing, stolen, or lost human pathogen or toxin, including when an SSBA is not received within 24 hours of the expected date and time of receipt, require a notification to the PHAC and will be followed up on a case-by-case basis where additional information may be required.

The notification report provides the PHAC with a description of the incident, including the following information:

For reports involving incidents where an SSBA has not been received within 24 hours of the expected receipt, the report should also contain the following information:

2.2 Other events requiring notification

2.2.1 Changes affecting containment

Before making any changes to the physical structure of a facility, to any equipment, or to any standard operating procedures (SOPs) that could affect containment, a licence holder must notify the PHAC of their intent to make such a change.

The notification report provides the PHAC with a description of the proposed changes to a facility, equipment, or SOP that could affect containment, and should include the following information:

2.2.2 Prohibiting a holder of an HPTA Security Clearance from accessing a part of the facility

When a licence holder decides to prohibit the holder of a HPTA Security Clearance from having access to a part of the facility to which the licence applies, they must notify the PHAC without delay.

The notification report provides the PHAC with information regarding the reason that the holder of a HPTA Security Clearance was prohibited from having access to the facility.

Although a notification report can be submitted using the Portal, please contact the Centre of Biosecurity at pathogens.pathogenes@phac-aspc.gc.ca or at 1-613-957-1779 BEFORE submitting a notification report. If the report is being submitted through the Portal, please do not include sensitive personal information.

2.2.3 Exemption from a Risk Group – Risk Group Reduction

A licence holder must notify the PHAC without delay when a Risk Group 2 (RG2), RG3, or RG4, human pathogen has been modified to the extent that it no longer meets the respective risk group definition, thereby potentially resulting in a risk group change. For example, if a an RG3 biological agent was modified such that it was no longer "likely to cause serious disease in a human", then it may no longer meet the definition of a RG3.

The notification report should provide the PHAC with a description of the modification and include:

This is followed by a pathogen risk assessment as described in Section 3.3.2.

Chapter 3 – Next Steps

3.1 Laboratory Incident Investigation

In accordance with the requirements specified in the CBS (Matrix 4.9), any incident involving pathogens, toxins, other regulated infectious material, infected animals, or failure of containment systems or control systems must be investigated and documented in order to determine the root cause(s).

While some guidance has been provided in Appendix B (Investigation and Analyzing Incidents), additional guidance on how to perform an investigation and root cause analysis is also available in the CBH and in a guideline available from the PHAC.

3.2 Laboratory Incidents

For incidents other than exposures/LAIs, the PHAC may request the facility to complete an Incident Investigation and Reporting Form to be submitted within a specified timeframe.

3.2.1 Exposure Follow-up Report

All exposure/LAI incidents require an exposure follow-up report documenting the results of the investigation, as known at the time the submission is due. Although the investigation may not be fully complete, the exposure follow-up report must be completed and submitted, with as much detail as is known and available, within the following timelines set out in Matrix 4.9 of the CBS:

See Appendix A for detailed guidance on how to complete the exposure follow-up report using the Portal.

3.3 Other events requiring notification

3.3.1 Prohibiting a holder of an HPTA Security Clearance from accessing a part of the facility

If a notification report is submitted through the Portal, a representative from the Centre for Biosecurity will contact the reporter.

3.3.2 Exemption from a Risk Group – Risk Group Reduction

Once the notification report has been submitted, regulated parties must conduct a pathogen risk assessment on the modified human pathogen or toxin and submit it to the PHAC for validation. If there is evidence to support the reduction in risk group, an amendment to the licence may be necessary. Please contact the PHAC at pathogens.pathogenes@phac-aspc.gc.ca for additional information and guidance on how to perform a pathogen risk assessment. A guideline on pathogen risk assessments is also available from the PHAC.

Chapter 4 – Glossary

It is important to note that while some of the definitions provided in the glossary are universally accepted, many of them were developed specifically for the CBS, or the CBH; therefore, some definitions may not be applicable to facilities that fall outside of the scope of the CBS.

Biological agent
In the case of this guideline and the Biosecurity Portal, a human pathogen or toxin.
Biological safety officer (BSO)
An individual designated for overseeing the facility's biosafety and biosecurity practices.
Biosafety
Containment principles, technologies, and practices that are implemented to prevent unintentional exposure to infectious material and toxins, or their accidental release.
Containment
The combination of physical design parameters and operational practices that protect personnel, the immediate work environment, and the community from exposure to biological material. The term "biocontainment" is also used in this context.

Appendix A – Exposure Reporting

A.1 Exposure Notification Report

The following information is provided to assist licence holder representatives and BSOs in completing and submitting a notification report using the Portal.

If the Portal is unavailable (or for voluntary reporting) the PHAC must still be notified of the incident and this can be done via email to:

pathogens.pathogenes@phac-aspc.gc.ca

Please refer to the Biosecurity Portal User Guide for guidance on how to access the Portal and reporting module.

All fields should be completed if and when the information is available; fields marked with an asterisk (*) are mandatory to complete prior to saving or submitting the exposure notification report.

Tip: remember to save early and often!

Privacy reminder: Do not include any personal name(s) or other personally identifying information on affected individuals anywhere in the report.

A.1.1 Administrative Information

Select "exposure" if an incident has involved individual(s) contact with or close proximity to infectious material or toxins that may result in infection or intoxication, respectively. Select "Laboratory acquired infection suspected" or "Laboratory acquired infection – confirmed" if an illness or infection/disease state (including seroconversion) is likely or confirmed as linked to a prior laboratory exposure incident.

Note: In the exposure follow-up report this field can also be used to rule out a previous notification of an exposure incident. If, at a later date, exposure is ruled out by the investigation (i.e., the investigation determined that either no pathogen or toxin was present or that there was no possibility of close contact that could have resulted in infection or intoxication of the person(s) in close proximity during the incident), the option "Ruled Out" can be selected from this field in the exposure follow-up report and no further information is required.

A.1.2 Occurrence Information

A.1.3 Submission Information

A.2 Exposure Follow-Up Report

The following information is provided to assist licence holder representatives and BSOs in completing and submitting an exposure follow-up report using the Portal. While only one exposure notification report can be submitted for an incident, multiple exposure follow-up reports can be submitted for the same incident as the investigation progresses.

If the Portal is unavailable an exposure follow-up report must still be submitted to the PHAC's email address pathogens.pathogenes@phac-aspc.gc.ca. Contact the PHAC to obtain a copy of the Incident Investigation and Reporting Form to facilitate submission of the required information.

Please refer to the Biosecurity Portal User Guide for guidance on how to access the Portal and reporting module.

Note: For exposure follow-up report fields that are identical to those in the exposure notification report, the information previously submitted will be prepopulated to fill these fields.

Reporters only need to review and revise the information in these fields if, as a result of the findings of incident investigation, the information previously submitted has now changed.

All fields should be completed if and where the information is available; fields marked with an asterisk (*) are mandatory to complete prior to saving or submitting the exposure follow-up report.

A.2.1 Administrative Information

A.2.1.1 Affected Persons

For each affected person identified in the above question add an affected person record and complete the required fields.

Note: Due to the design limitations of the current iteration of the Portal, each affected person record must be saved before adding a new affected person record or returning to the administrative information page. By saving the record, additional fields related to the biological agent involved in the incident will appear and must be completed before the overall report can be submitted to the PHAC. If these additional fields have not been completed for each affected person, the system will not allow you to submit the report and an error message will be generated, indicating that information is missing in the Administrative Information section.

Privacy reminder: Do not include any personal name(s) or other personally identifying information on affected individuals anywhere in the report.

A.2.1.1.1 Laboratory Experience and Role(s)

Appendix B – Investigating and Analyzing Incidents

B.1 Investigating Incidents

This section describes the general principles and key steps involved in conducting an incident investigation and root cause analysis. From gathering thorough and credible information to conducting a comprehensive and systematic analysis of the evidence, the ultimate aim is to prevent a recurrence of the incident. Root cause analysis is a standardised method of deconstructing what happened leading up to and during an incident to explore the factors that contributed to the incident (casual factors) and uncover the initiating causes (root causes) that underpin each of these contributing factors. Through this process, causal pathways are defined and connect each causal factor back to its corresponding root cause(s), thus enabling a thorough and objective definition of problems and gaps in the system. On this foundation, unbiased interventions that target the root problems and issues at the base of each causal pathway can be planned and implemented (corrective action plan) to prevent a recurrence of the incident.

B.1.1 General Principles

B.1.2 Conducting an Investigation and Follow-up Actions

This section provides a high-level overview of the key steps involved in an investigation process. This is intended as guidance only and is provided as an aid for collecting, organizing, and analyzing the facts surrounding an incident.

Additional guidance on incident reporting and investigation can be found in Chapter 18 of the CBH. For specific requirements and timelines for exposure notification and reporting refer to matrix 4.9 of the CBS and corresponding explanatory notes.

Figure B-1 illustrates the general steps involved in performing an incident investigation. Although the time required to conduct each step of the investigation will depend on the type, complexity, and severity of the incident, some approximate timelines are provided below. For the most part, steps will proceed in a sequential manner, although some elements of each step may overlap in time. For example, collection of information (beginning of Step 2) may begin before or at the same time that a notification (end of Step 1) is being prepared and submitted to internal (within the institution) or external (to the PHAC and/or other regulators) authorities.

  • Evaluate the effectiveness of corrective actions in the control of root causes

B.1.3 Initial Response

Although outside the scope of this guidance document, which aims to provide guidance for incident notification and reporting to the PHAC, the initial response to an incident (prior to notification/reporting at the latter end of this step) is critical for assessing the incident and responding to hazards. These immediate response actions can include providing first aid and/or other emergency services to the affected individuals, and controlling and/or containing the hazard to prevent/mitigate further harm. In addition, assessing available information, checking equipment status, documenting the names of persons involved in the event, and securing and preserving initial evidence should be part of the initial response once personnel have been treated and hazards have been controlled. Likewise, the formation of an investigation team with a defined scope, objectives, and roles should occur very early in the investigation process. This investigation team will likely consist of the BSO and others, depending on the type of incident.

At the latter end of the initial response step, an incident assessment, including exposure assessment, should be conducted to characterise the incident for immediate reporting to internal authorities and determine whether the incident requires immediate notification to external authorities (i.e., PHAC).

Notification to the PHAC without delay (i.e., as soon as reasonably possible) permits time for immediate response and control measures to be taken, while still providing a timely alert to the PHAC.

B.1.4 Collection of Evidence and Information

The amount and type of evidence/information gathered to describe and analyze a given incident will vary depending on the severity, complexity, extent, and/or uniqueness of the incident. The evidence collected must be sufficient to thoroughly document what happened and describe who, when, where, and how the event unfolded. For incidents that may not need to be formally reported (e.g., an incident involving a human pathogen or toxin where no known exposure, release, inadvertent possession, or other reportable incident is thought to have occurred), the incident should be investigated (as a near miss) and be fully documented should there be a need to reassess the evidence in the future. For example, if an incident was earlier ruled out as an exposure but later an individual who was in close proximity develops an associated illness, within a relevant timeframe, the investigation details should be reviewed to explore the possibility of an unrecognized exposure linked to the incident.

Initial information gathered may include (but is not limited to):

B.1.4.1 Incident timeline

A timeline is a simple yet effective way to identify gaps and missing information. Any associated information or conditions about the actions that contributed to the incident should be included in the timeline. It is difficult to determine if details are relevant until after the timeline is built.

B.1.4.2 Causal factors

The causal factors are errors or failures that, if corrected or eliminated, could have (i) prevented the incident from occurring or (ii) mitigated its results. For most incidents, there are multiple causal factors, any one of which could have changed the outcome of the incident. It is a good practice to take time with all those involved in the incident and any subject matter experts assisting with the investigation to come to an agreement on causal factors.

B.1.5 Analysis and Identification of Root Causes

As part of the incident investigation, the root cause(s) for each identified causal factor should be established. Root causes are the most basic, underlying reason a problem or causal factor exists. Most root cause analyses start by identifying general problems then continued questioning until specific, underlying system weaknesses, failures, or gaps have been defined that could have prevented the causal factor from existing.

B.1.6 Corrective and Preventive Actions

Corrective and preventive actions eliminate or mitigate the root causes of an exposure/incident, or reduce the likelihood or consequence of a similar occurrence happening again.

B.1.7 Evaluation and Continual Improvement
