Using the Template

The Tailored Information and Studies Guidelines (TISG) are a key document of the impact assessment process that outlines the required information and studies that the proponent must include in its Impact Statement to assess the effects of its project. The Impact Assessment Agency of Canada (IAAC), or the independent review panel, will consider the information and studies received from the proponent, as well as other information, knowledge and input gathered through the impact assessment process when drafting the Impact Assessment Report. This report will inform federal decision making under the Impact Assessment Act.

The Government of Canada is committed to meeting the objective of “one project, one review”. IAAC will work to avoid duplication with other jurisdictions (e.g. provincial governments), and to increase efficiency when developing project-specific TISG. This may include issuing joint TISG, deferring to the requirements of other jurisdictions where overlap exists (e.g. provincial regulatory requirements), and/or leveraging the means of other jurisdictions to simplify requirements (e.g. relying on provincial standards). In addition to following relevant cooperation agreements, IAAC is committed to recognizing the requirements of other processes – including provincial processes and federal permits – to eliminate duplication. For assessments substituted to a provincial process, the TISG will be developed by the other jurisdiction. For assessments substituted to a harmonized process; IAAC, the other jurisdiction (e.g. province) or both together may develop the TISG.

The following Tailored Information and Studies Guidelines Template (the Template) is the starting point to tailor project-specific TISG. Project-specific TISG will be tailored to focus on key issues material to decision making following the impact assessment based on the project and its context, as well as on available information and knowledge.

To facilitate tailoring, the Template includes tailoring guidance that identifies when requirements are anticipated to be relevant only in specific circumstances – these are presented in square brackets throughout the Template. Tailoring instructions are in blue highlight. Additional requirements beyond those in the Template may be included in the TISG for individual projects, where required.

The Template uses the term “must” to identify requirements (i.e. elements that have to be followed). However, the Template will be tailored to specific projects, including project-specific key issues, and thus not all requirements in the template will necessarily apply to all projects (i.e. some will be tailored out). Other terms such as “encourage” are intended to provide recommendations that will support an efficient process.

In the Template, the term "Indigenous group" refers to a collective of Indigenous People who hold Aboriginal and/or treaty rights as recognized and affirmed in section 35 of the Constitution Act, 1982; while “Indigenous Peoples” is a collective term that refers to First Nations Peoples, Inuit and Métis Peoples in Canada. These are the three groups of Indigenous Peoples recognized by the Canadian Constitution. IAAC will work with the Indigenous groups identified for consultation and engagement for each project to determine the most appropriate terminology for project-specific TISG and the Indigenous Engagement and Partnership Plan. Terminology may vary, for example, Indigenous groups may be replaced with Indigenous communities and Indigenous Nations, and, in some cases, Indigenous organizations may be most appropriate.

The TISG will be issued to the proponent as part of the Notice of Commencement and posted to the Canadian Impact Assessment Registry Internet site.

1 Introduction

The federal impact assessment process prevents or mitigates significant adverse effects within federal jurisdiction — and significant direct or incidental adverse effects — by anticipating, identifying and assessing the effects of designated projects in order to inform decision making under the Impact Assessment Act (IAA). These Tailored Information and Studies Guidelines (TISG) for [insert: Name of project] (the project) proposed by [insert: Name of Proponent] (the proponent) were tailored by the Impact Assessment Agency of Canada (IAAC). The TISG specify the information and studies that IAAC considers necessary for the conduct of the impact assessment based on adverse effects within federal jurisdiction and direct or incidental adverse effects (collectively referred to as adverse federal effects hereafter) that could potentially be significant.

The proponent must prepare an Impact Statement that includes the information and studies outlined in these TISG, as well as the generic requirements for Impact Statements in Annex 1 [add Generic Requirements for Impact Statements as an annex to this document; state if elements of the generic assessment methodology are not required to be followed in order to support alignment with the process of another jurisdiction].

[Specify as applicable: The term “Impact Statement” refers to the information and studies that must be provided by the proponent in relation to the requirements of these TISG, including generic requirements in Annex 1. The information and studies may be provided as a single document or in a series of documents as set out in the Service Standard Agreement for the project.]

[IAAC or A review panel] will use the proponent’s Impact Statement along with other available information to prepare an Impact Assessment Report.

The proponent is encouraged to engage IAAC as early as possible to clarify the requirements in the TISG and to support early resolution of issues. The proponent is also encouraged to submit interim documents for early review by IAAC such as topic-based interim technical reports which can follow the sequence of the TISG which incorporate Indigenous and pubic engagement on the topic. A table of concordance can be provided to indicate where the information set out in these TISG has been provided. For an efficient review of submissions, IAAC may establish technical advisory groups comprised of Indigenous groups, federal authorities, provincial authorities and/or other relevant parties or experts.

Where the proponent is of the opinion that certain information is not required or cannot be provided, it should contact IAAC prior to submitting the Impact Statement to confirm whether the proponent’s rationale for excluding the information is appropriate. The rationale must also be included in the Impact Statement. The proponent should also notify IAAC of any changes made to the project relative to the [insert: Initial Project Description or Detailed Project Description].

The proponent is encouraged to refer to the requirements of other jurisdictions to assess effects, as well as to provide information on how the means of other jurisdictions would mitigate adverse federal effects, including information about any mitigation measure that will be implemented by another jurisdiction. [In support of the Government of Canada’s objective of “one project, one review”, the TISG identify where the federal impact assessment and the assessment processes of Name of jurisdiction or lifecycle regulator have shared information needs and/or where the proponent is directed to follow the requirements of another jurisdiction.]

As relevant, the proponent may refer to IAAC’s website, for additional resources, including Technical Considerations and References for the preparation of an Impact Statement. Proponents should be aware that IAAC’s guidance on the practice of the IAA and its regulations is being updated, and some guidance on the website may not reflect the IAAC’s current practices. Proponents remain responsible for following applicable legislation and regulations. Proponents are encouraged to engage with IAAC regarding the applicability of the guidance. For more information, please contact [insert project contact].

1.1 Scope of the impact assessment

“[Edit as applicable] IAAC sets the scope of the assessment for the project taking into account the potential effects of the project and each of the factors listed in subsection 22(1) of the IAA. The factors in subsection 22(1) must be taken into account in an impact assessment, with the assessment focused on elements anticipated to be material to decision making. This scope is reflected in the selection of valued components set out in Section 1.2 Selection of Valued Components and in other requirements/direction throughout these TISG as well as in the generic requirements for Impact Statements in Annex 1, as applicable.

[Specify IAAC’s determination of the scope of factors referred to in paragraphs 22(1)(a) to (f), (h) to (l) and (s) and (t), including the extent of their relevance to the impact assessment, under 18(1.2); specify if IAAC has identified other matter(s) relevant to the impact assessment under paragraph 22(1)(t).]

In addition, the Impact Statement must take into account, where relevant:

Where relevant, the Impact Statement must also take into account throughout the impact assessment Gender-based Analysis Plus (GBA Plus) which, in the context of an impact assessment, is an analytical tool and process that examines how sex and gender intersect with other identity factors to assess who may be disproportionately impacted by a project and how they may experience impacts differently. It helps identify the diverse experiences and needs of various population groups and informs strategies to mitigate barriers and promote equitable access to project benefits.

The TISG set out information and studies required in the proponent’s Impact Statement. The TISG also set out [If applicable: specify the information or studies relevant to the impact assessment where IAAC will rely on publicly available information (e.g. the Initial Project Description) or requirements from other means (e.g. frameworks, standards, legislations or regulations from another jurisdiction) instead of requiring information or studies from the proponent through these TISG.]

1.2 Selection of Valued Components

Valued Components (VCs) serve as the focal points of these TISG and of the impact assessment. IAAC selects, as VCs, the elements of the natural and human environments anticipated to be material for decision making following the impact assessment under the IAA. The assessment of effects on VCs must consider the likely effect pathways between project components or activities and the VC, with a focus on those effect pathways that are key issues.

The Impact Statement must include, at minimum, the following VCs [tailor based on VCs material to IAA decision making and any relevant key issue(s) for each VC including as informed by the perspectives from Indigenous groups and others]:

Valued Component (VC) selected

Key issues

VCs for the assessment of adverse effects within federal jurisdiction, as defined under section 2 of the IAA and impacts on Indigenous groups

 

Fish and fish habitat

[e.g. Habitat loss from works in water, water withdrawal as well as risk of contamination of watercourses through acid rock drainage and metal(loid) leaching from excavation, etc.]

[Where non-negligible adverse changes to other aquatic speciesFootnote 1 are likely to result from the project: Marine plants]

[e.g. Removal and burial of coastal vegetation from dredging, etc.]

[e.g. Loss of access to preferred harvesting locations and disruptions in the marine environment used for fishing and boating, etc.]

Health, social and economic conditions of Indigenous Peoples

[e.g. Air emissions, increased noise and light levels and increased exposure to gender-based violence from construction and operation activities, etc.]

[If the project – or a physical activity that is part of the project – is a federal work or undertakingFootnote 2 or carried out on a federal landFootnote 3 and additional non-negligible adverse changes are likely to result from the project or the identified physical activity: list elements(s) not already listed above anticipated to be material to decision making]

[e.g. For commercial fishing VC: No-fishing zones, marine shipping and habitat loss resulting from the construction and operation of the marine terminal – a federal work and undertaking, etc.]

[if required: Additional VCs for the assessment of direct or incidental adverse effects, as defined under section 2 of the IAA]

 

[If a federal permit, authorization or financial assistance by a federal authority (collectively referred to as federal decision) would enable the carrying out of a project, either in whole or in part and additional non-negligible adverse changes are likely to result from that federal decision: list element(s) not already listed above anticipated to be material to decision making]

[e.g. For recreational fishing VC: Loss of access nearshore that would result from a Fisheries Act authorization for the destruction of fish habitat for project construction, etc.]

Additional VCs for decision-making factors under section 63 of the IAA

 

[List additional element(s) not already listed above likely contributing to Canada’s environmental obligations, climate change commitments, or to sustainability.]

[e.g. For climate change commitments: Reduced domestic greenhouse gases through carbon capture and offsets, etc.]

[e.g. For environmental obligations: Increased regional biodiversity through habitat restoration and green infrastructure, etc.]

[e.g. For sustainability: Improvements to well-being through increased community cohesion, employment and income, etc.]

In focusing on information anticipated to be material to decision making under the IAA, the Impact Statement must also describe impacts on Indigenous rights.

Indigenous rights

Key issues

Adverse impacts on the ability of Indigenous Peoples to exercise their rights

[e.g. Ability of Indigenous Peoples to exercise their harvesting rights due to reduced access, etc.]

The proponent may select additional VCs through discussions with Indigenous groups and participants as well as in consideration of Indigenous Knowledge and community knowledge. Any additional VC should be related to adverse federal effects or IAA decision-making factors. Reasons for excluding a VC suggested by an Indigenous group should be discussed with the Indigenous group. The Impact Statement must include Indigenous groups’ perspectives on the selection of VCs and a justification if a VC suggested by an Indigenous group is excluded.

VCs must be assessed following the requirements presented in these TISG, as well as the generic assessment methodology in Annex 1 which outlines the steps that must be applied to the assessment of each VC. [State if elements of the generic assessment methodology are not required to be followed in order to support alignment with the process of another jurisdiction.]

1.3 Federal permitting coordination

IAAC will provide coordination of federal permits, licences or authorizations (collectively called permits) early and throughout the impact assessment process to provide:

The proponent is encouraged to develop federal permit applications concurrently with the impact assessment. Collecting and providing permitting information during the impact assessment process will expedite subsequent federal decisions. Early engagement with the federal government, Indigenous communities and the public is essential to support a speedy review of federal permits.

2 Project description

2.1 Project overview

The project subject to the impact assessment is the designated physical activity [specify] and any incidental physical activity [specify, as applicable].

The Impact Statement must:

2.2 Project components and activities

The Impact Statement must:

2.3 Receiving environment

The Impact Statement must describe the project’s receiving environment in sufficient detail to assess the effects of the project on VCs and on impacts on Indigenous rights and, where appropriate, locate on map(s), including:

2.4 Project purpose, need and alternatives considered

The proponent must identify the purpose of and need for the project, as well as alternatives to the project and alternative means of carrying it out in consideration of the perspectives and suggestions of Indigenous Peoples, the public and other participants.

2.4.1 Purpose of the project

The Impact Statement must outline what the proponent intends to achieve by carrying out the project, broadly classify the project type (e.g. [insert as applicable: transportation, electricity supply, mineral extraction]) and indicate the target market (e.g. international, domestic, local).

2.4.2 Need for the project

The Impact Statement must describe the underlying opportunity or issue that the proponent intends to seize or solve by carrying out the project, such as demand for a resource or support for a federal or provincial government objective, and provide a rationale that the project is a warranted response.

2.4.3 Alternatives to the project

[If sufficient information was provided in the Planning phase on ‘alternatives to’: IAAC will rely on the proponent’s insert as applicable: Initial Project Description, Detailed Project Description or response to the Summary of Issues insert as applicable: demonstrating that there are no or describing “alternatives to” the project that are technically and economically feasible to meet the need for the project and achieve its purpose. No additional information is required.]

[If further information on ‘alternatives to’ is required: The Impact Statement must:

2.4.4 Alternative means of carrying out the project

[If the project is subject to Schedule 2 of the Metal and Diamond Mining Effluent Regulations (MDMER): To support more efficient federal permitting, the proponent is encouraged to provide an assessment of alternatives for mine wasteFootnote 4 disposal in the Impact Statement that follows Environment and Climate Change Canada’s (ECCC) Guidelines for the assessment of alternatives for mine waste disposal. Doing so can reduce the time needed to obtain an amendment to Schedule 2 of the MDMER, if required for the disposal of mine waste into waters frequented by fish. For further guidance, the proponent can refer to the Guide To The Regulatory Process For Listing Water Bodies Frequented By Fish In Schedule 2 Of The Metal And Diamond Mining Effluent Regulations.]

The Impact Statement must:

3 Fish and fish habitat [and marine plants]

The impact assessment must assess the effects of the project on fish and fish habitat, as defined in subsection 2(1) of the Fisheries Act [insert as applicable: and on marine plants, as defined in section 47 of the Fisheries Act] based on likely effect pathways from project components or activities.

Where authorization(s) under section 34.4(2)(b) or 35(2)(b) of the Fisheries Act are likely required for the project, the proponent is encouraged to provide the information required for permitting during the impact assessment in support of an efficient and shortened permitting approval process, and refer to Project Planning: Applying for a Fisheries Act Authorization and the Applicant’s Guide Supporting the Authorizations Concerning Fish and Fish Habitat Protection Regulations. [For projects requiring an MDMER Schedule 2 amendment: This information can also reduce the time needed to obtain an authorization to deposit mine waste into a tailings impoundment area if a regulatory amendment to list the water frequented by fish on Schedule 2 of the MDMER is required. For further guidance, the proponent can refer to the Guide to the Regulatory Process for Listing Water Bodies Frequented by Fish in Schedule 2 of the Metal and Diamond Mining Effluent Regulations.]

3.1 Baseline conditions for fish and fish habitat [and marine plants]

The Impact Statement must:

3.2 Effects to fish and fish habitat [and marine plants]

The Impact Statement must:

4.2 Effects to migratory birds

The Impact Statement must:

[Other VC(s) selected by IAAC related to adverse federal effects]

[If applicable, add requirements anticipated to be material to IAA decision making for the additional VC(s) identified by IAAC related to adverse federal effects in section 1.2 Selection of Valued Components. Additional VC(s) can be presented in separate sections of the TISG, or combined with other VCs, and may include:

5 Indigenous Peoples

The Impact Statement must demonstrate how impacts on Indigenous Peoples and their rights were considered and assessed, including:

Indigenous Peoples are best placed to understand how a project may impact them. The assessment of impacts on Indigenous Peoples and their rights must be done in collaboration with Indigenous groups as outlined in the Description of engagement with Indigenous groups. Where relevant, the proponent must collaborate with Indigenous groups to incorporate information from or about them into the assessment of all VCs.

The proponent is expected to engage with all Indigenous groups impacted by the project, as set out in the Indigenous Engagement and Partnership Plan (IEPP), and to describe the outcomes of that engagement in the Impact Statement. In addition, the results of engagement should be analyzed and presented separately for each Indigenous group. This group-specific assessment does not need to repeat the entire analysis of each VC, but should summarize and present the information relevant to that group. To the extent possible, each group-specific assessment should be done in a way that works best for that Indigenous group.

The proponent must include conclusions on the potential impacts on Indigenous Peoples and their rights for each of the Indigenous groups affected by the project. If an Indigenous group has provided their own conclusions, those conclusions must be included in the Impact Statement. In that case, the proponent is not required to provide separate conclusion and should discuss with each Indigenous group whether it is appropriate for the proponent to provide their views on those conclusions.

Where requested by Indigenous groups, parts or all of the assessments of effects on Indigenous Peoples and their rights can be combined in the group-specific assessment. For example, effects on the current use of lands and resources for traditional purposes and impacts on Indigenous rights to hunt, fish, and trap can be reported together. Indigenous groups may also identify holistic VCs that encompass multiple environmental, health, social, or economic elements. Undertaking these assessments together, when requested, will support consistent conclusions.

In all cases, the Impact Statement must demonstrate that all requirements were met.

5.1 Indigenous physical and cultural heritage, and structures, sites, or things of significance

The Impact Statement must:

6 Contributions to inform decision making

At the decision-making phase of the IAA, should the decision maker determine that the adverse federal effects that are likely to be caused by the project are likely to be, to some extent, significant, the decision maker will decide whether they are justified in the public interest in light of the extent to which they are significant and of the factors set out in section 63 of the IAA. This section of the TISG outlines information that would inform IAAC’s analysis of certain section 63 factors.

6.1 Canada’s environmental obligations and climate change commitments

IAAC, with the support of federal authorities, will analyze the extent to which the project’s likely effects contribute to Canada’s ability to meet its environmental obligations, as well as Canada’s commitments in respect of climate change. [If applicable: The information gathered during the Planning phase suggests that the project would not contribute to meeting biodiversity obligations and/or GHG emission targets provide short rationale.] Where the proponent is of the view that the likely effects of the project would contribute to Canada’s environmental obligations and/or commitments in respect of climate change, the proponent is encouraged to substantiate this view in the Impact Statement by describing these likely effects and the extent of their contribution (e.g. net increase in biodiversity through ecosystem restoration; net GHG emission reductions through the deployment of carbon capture and storage).

6.1.1 Environmental obligations

Federal environmental obligations relevant to this project include those set out in the following instruments:

Biodiversity
[insert if applicable: Air quality]
[insert if applicable: Water quality and quantity]

[insert if applicable: other relevant environmental obligations].

The Impact Statement must:

Where the proponent is of the view that the likely effects of the project contribute to environmental obligations, the proponent is encouraged to:

6.1.2 Climate change commitments

Where the proponent is of the view that the likely effects of the project contribute to Canada’s climate change commitments, the proponent is encouraged to describe its plans and commitments accordingly.

Greenhouse gases emissions

The proponent [if the project, as a whole, is a federal work or undertaking or on federal lands: must; otherwise: may] assess the project’s GHG emissions following the Strategic Assessment of Climate Change (SACC) and the technical guides related to the SACC, developed by ECCC, including the Guidance on quantification of net GHG emissions, impact on carbon sinks, mitigation measures, net-zero plan and upstream GHG assessment. [If component(s) of the project federal work or undertaking or on federal lands: At minimum, the proponent is required to provide the information as it relates to insert name of the project component(s).] The proponent is encouraged to keep apprised of updates to the SACC and related technical guides published by ECCC.

6.2 Sustainability

Sustainability is the ability to protect the environment, contribute to the social and economic well-being of the people of Canada and preserve their health in a manner that benefits present and future generations. Information throughout the TISG can be used to support the analysis of the extent to which the likely effects of the project contribute to sustainability.

6.2.1 Social and economic well-being

[If relevant, include this section and align it, including its title and content, with the VC(s) selected by IAAC as likely contributing to sustainability in section 1.2 Selection of Valued Components.

Where the proponent is of the view that the likely effects of the project contribute to sustainability, the proponent is encouraged to analyze the project’s effects on the well-being of non-Indigenous peoples, in addition to analyzing the well-being of Indigenous groups following requirements in the Indigenous Peoples section of the TISG, and include in its Impact Statement a description of:

6.2.2 Extent to which the likely effects of the project contribute to sustainability
