Ontario Provincial Environmental Review (9-ON-a)

Information current as of 2022
In Ontario, a developer may need approval from the Ontario Ministry of the Environment, Conservation and Parks (Ministry) for an undertaking pursuant to the Ontario Environmental Assessment Act. R.S.O. 1990, c. E.18, s. 5(3). An undertaking is defined as "a major commercial or business enterprise or activity or a proposal, plan or program...that is designated by the regulations." R.S.O. 1990, c. E.18, s. 1. Projects less than 115 kV are excluded from any definition of undertaking. O. Reg. 116/01, s. 3(1), 4(1).

Ontario Regulation 116/01, Electricity Projects does not apply to transmission lines associated with a generation facility that either:

  • Constructed as a back-up for the site, or
  • Uses biogas, biomass, landfill gas, natural gas, or waste biomass as its primary power source, has a nameplate capacity of 25 MW or less, and either:
    • does not sell any electricity to the IESO-administered markets and does not distribute any electricity offsite, or
    • has a ratio of output energy to input energy of more than 0.60.

O. Reg. 116/01, s. 2(1).

Under the act, the developer may be required to undertake an environmental review pursuant to the Environmental Screening Process as outlined in Part B of the Guide to Environmental Assessment Requirements for Electricity Projects. Ontario Environmental Assessment Act; Electricity Projects Regulation. Alternatively, a developer must undertake an environmental assessment (EA) if the Minister of the Environment, Conservation and Parks (Minister) can still give the developer a notice to prepare an EA. O. Reg. 116/01, s. 4(5).

The Ontario Ministry of the Environment, Conservation and Parks regulates provincial environmental reviews of transmission projects pursuant to the Ontario Environmental Assessment Act and the Electricity Projects Regulation.



Provincial Environmental Review Process


9-ON-a.1 – Is the Project Associated With a Category B Generation Facility?

A developer must pursue the Environmental Screening Process if the project is more than 2 (two) kilometers (km) in length, designed to transmit electricity at 115 kilovolts (kV) or more, and is not associated with a Category B generation facility. O. Reg. 116/01, s. 4(1), (4). Category B generation facility are defined as:

  • A generation facility that has a name plate capacity of one megawatt or more but less than five megawatts and that uses oil as its primary power source;
  • A generation facility that has a name plate capacity of less than 200 MW and that uses water power as its primary power source;
  • A generation facility that has a name plate capacity of two (2) MW or more and that uses wind energy as its primary power source;
  • A generation facility that has a name plate capacity of five (5) MW or more and that uses biomass or natural gas as its primary power source;
  • A generation facility that has a name plate capacity of 10 MW or more and that uses waste biomass as its primary power source;
  • A generation facility that has a name plate capacity of 25 MW or more and that uses biogas as its primary power source; or
  • A generation facility that has a name plate capacity of 25 MW or more, uses landfill gas as its primary power source and is located at a waste disposal site the establishment of which does not or did not require approval under section 5 of the Ontario Environmental Assessment Act.

R.S.O. 1990, c. E.18, s. 5(1); O. Reg. 116/01, s. 4.

Projects in this category are still subject to the Ontario Environmental Assessment Act, but are exempt from completing the Environmental Assessment (EA) process if the developer fulfills the requirements of the Environmental Screening Process as outlined in Part B of the Guide to Environmental Assessment Requirements for Electricity Projects. This Guide is given the force of law under section 42(1) of the Ontario Environmental Assessment Act and section 1(1) of the Electricity Projects Regulation. See 9.27.

Even if a project qualifies to use the Environmental Screening Process, the Minister of the Environment, Conservation and Parks (Minister) can still give the developer a notice to prepare an EA. O. Reg. 116/01, s. 4(5).

9-ON-a.2 – Provide Notice of Commencement of a Screening

A developer must provide a public Notice of Commencement of Screening in at least one local newspaper with circulation in the vicinity of the project. If there are no newspapers with circulation in the vicinity of the project, the developer must determine another equivalent method of providing notice to the general public. The developer must also mail or deliver notice to:

  • Adjacent landowners and tenants;
  • The EA Coordinator at the appropriate Regional Office of the Ministry of the Environment, Conservation and Parks;
  • The local Ministry of Natural Resources and Forestry office (for hydroelectric projects);
  • Other affected government agencies and municipalities; and
  • Other potentially interested or affected parties such as local interest groups, businesses, and members of the public that may be directly affected by some aspect of the project.

The notice must include:

  • The name of the developer;
  • A brief description of the project;
  • A map showing the project location;
  • A statement that the project is subject to the Ministry of the Environment, Conservation and Parks Environmental Screening Process for electricity projects; and
  • A contact name, address, and phone number.

Any notice required to be given by the Environmental Screening Process may be given together with notices required by other statutes if the notice clearly states which notices are being combined and includes all required information for each notice. Guide to Environmental Assessment Requirements for Electricity Projects.

The developer can also voluntarily skip to the environmental review if they decide that the project entails significant negative environmental effects or public issues that warrant a more detailed look. See 9.16 for the environmental review within the Environmental Screening Process.

9-ON-a.3 to 9-ON-a.4 – Prepare Project Description Outline

A developer must begin the screening phase of the Environmental Screening Process by preparing a project description outline that includes all phases and components of the project through the project's construction, operation, and retirement. If the developer knows of any future planned expansions while applying the Environmental Screening Process, those details are considered part of the project. The screening can rely primarily on existing and/or readily obtainable information. Guide to Environmental Assessment Requirements for Electricity Projects.

The developer must then apply the screening criteria to the project as described in the project description outline, which requires the developer to answer a series of yes-or-no questions about the project. The purpose of the screening criteria is to identify potential negative environmental effects the project could have. If the developer determines that the project may have a negative environmental effect that can be addressed with mitigation measures, the developer will still need to respond "yes" to that question so that the developer's mitigation plans can be reviewed later by agencies and the public. The screening criteria can be located in Appendix C of the Guide to Environmental Assessment Requirements for Electricity Projects.

9-ON-a.5 – Prepare a Screening Report (If Applicable)

The developer can skip issuing a screening report and move directly to the environmental review stage of the Environmental Screening Process (beginning at 9.16) if during the screening stage that the project includes potential environmental effects or public concerns that require further assessment and resolution. In making this decision, the developer should consider:

  • The success of attempts to minimize effects through the selection of the site, the technology, the facility design, or through the use of reasonable mitigation and impact management;
  • How effectively the proponent can, or is prepared to, manage any negative effects or resolve issues and address concerns;
  • The significance of any net effects;

how commitments to future actions are accepted by government agencies, nongovernment organizations, the community and affected property owners; and

  • Whether additional studies and analysis are likely to provide tangible results.

Guide to Environmental Assessment Requirements for Electricity Projects.

The developer must prepare a Screening Report to record the results of the screening if there are no likely significant negative effects, no unresolved concerns, and the advantages of the project outweigh the disadvantages. A Screening Report must include the following:

  • Background information including a description of the project, the purpose of the project and an outline of the basic technologies to be used;
  • A map of the project location;
  • A description of the local environment and conditions;
  • A description of any other required approvals and permits;
  • A completed screening criteria checklist;

information, analysis and discussion of mitigation and impact management measures for any potential negative effects identified through application of the screening criteria, including an assessment of the significance of any net effects;

  • Commitments to mitigation, impact management, monitoring and/or further consultation and the mechanisms for their implementation and reporting;
  • Information on public and agency consultation, including:
    • A description of the public and agency consultation program and consultation activities/events;
    • A list of agencies contacted or consulted;
    • A summary of public and agency concerns or issues, and how they have been resolved or addressed;
    • Copies of key public and agency comments;
    • A description of how environmental effects or issues may be addressed through other required approvals;
    • A review of the overall environmental advantages and disadvantages of the project, to include discussion of any benefits that may offset negative environmental effects; and
    • A summary of all mitigation, impact management and monitoring commitments.

Guide to Environmental Assessment Requirements for Electricity Projects.

Supporting information like technical reports must be referenced in the Screening Report but do not have to be included in the Screening Report itself. However, the developer must supply any such supporting information and any correspondence about the Environmental Screening Process if an agency or a member of the public requests it. The developer should also send a partial or complete draft of the Screening Report to any key agencies and stakeholders for comments before the formal review period. Guide to Environmental Assessment Requirements for Electricity Projects.

9-ON-a.6 – Provide Notice of Completion of a Screening Report

The developer must provide Notice of Completion of a Screening Report and publish it in at least one local newspaper with circulation in the vicinity of the project. If there are no newspapers with circulation in the vicinity of the project, the developer must determine another equivalent method of providing notice to the general public. The notice must include:

  • The information required for the Notice of Commencement of a Screening (description of the project, proponent, location, project is being reviewed under the Ministry of the Environment, Conservation and Parks' Environmental Screening Process for electricity projects, and contact information);
  • The results of the Screening (e.g., there are no significant negative effects, the proponent intends to proceed with the project subject to mitigation, other commitments and other approvals);
  • The location(s) where the Screening Report may be reviewed;
  • Notification that:
    • If a concerned party has outstanding environmental concerns about the project, it should raise these concerns with the proponent;
    • If the proponent and the concerned party are unable to resolve the matter, the concerned party can make a written request to the Director of the EAAB, Ministry of the Environment, Conservation and Parks to elevate the project to either an Environmental Review or to an individual EA. A copy of the elevation request must be sent to the proponent;
    • Elevation requests must be made in accordance with the provisions set out in the Ministry of the Environment, Conservation and Parks' Environmental Screening Process for electricity projects;
  • The address of the Director of the EAAB, Ministry of the Environment, Conservation and Parks;
  • The last date when requests for elevation will be received.

The developer is also required to mail copies of the notice to the EA Coordinator at the appropriate Regional Ministry of the Environment, Conservation and Parks office, adjacent landowners and tenants, and anyone else who has expressed an interest in the project. In addition to those people, the developer should also mail notices to other potentially affected and interested agencies, municipalities, landowners, residents, businesses, and local interest groups regardless of whether these people have expressed interest in the project.

Guide to Environmental Assessment Requirements for Electricity Projects.

9-ON-a.7 – Review Screening Report

The developer must make the Screening Report available for public and agency review for 30 calendar days in a "convenient" location in the project area, such as a public library, municipal building, or community center, and include the location in the notice. The developer should also try to make the Screening Report available on the internet if possible. Guide to Environmental Assessment Requirements for Electricity Projects.

Concerned parties are encouraged to inform the developer of their concerns before taking any official action. The developer should be prepared to resolve any concerns that may be flagged during the review period, and if the developer commits to address concerns raised during this review period, that commitment will be recorded and filed with the developer's Screening Report or Environmental Review Report. The developer is required to fulfill these commitments while pursuing their project. If it appears this process will take longer than the 30-day review period allows, the developer and the concerned party can together set an end date for their negotiations that is past the original 30 days and notify the Ministry's EAAB Director of the change. Guide to Environmental Assessment Requirements for Electricity Projects.

9-ON-a.8 to 9-ON-a.9 – Have There Been Any Requests to Elevate the Project?

The developer must submit a Statement of Completion to the Ministry of the Environment, Conservation and Parks when the 30-day review period ends and there have been no requests to elevate the project. The developer must retain a copy on site or somewhere it is readily available for the life of the project. A Statement of Completion signifies the end of the Environmental Screening Process and that the developer has satisfied the requirements of the Environmental Assessment Act. In implementing the project, the developer must adhere to the details of the Screening Report.

The developer must determine whether the project requires an Individual EA (IEA) or a Class Environmental Assessment for Minor Transmission Facilities (Class EA). A complete application for environmental review (Application) consists of Terms of Reference and either IEA or a Class EA, depending on the project. R.S.O. 1990, c. E.18, s. 5(2), 13(2). Even if a project would typically qualify to use a Class EA, the Minister can order a developer to instead comply with the IEA requirements. R.S.O. 1990, c. E.18, s. 16.

Note: This narrative will use Environmental Assessment, or "EA," to refer to both Individual Environmental Assessments and Class Environmental Assessments, as many of the requirements for each are identical. This narrative will use either IEA or Class EA only where the requirements apply to one or the other.

9-ON-a.32 – Terms of Reference

The developer must submit to the Minister proposed Terms of Reference that outline the preparation of the EA to be performed. R.S.O. 1990, c. E.18, s. 6(1), 13.2(1). The Terms of Reference must be on a form supplied by the Ministry and must include a statement that the environmental assessment will be prepared in accordance with the requirements set out in the Ontario Environmental Assessment Act, any requirements prescribed especially for the type of undertaking with which the developer wants to proceed, a detailed description of the requirements for the preparation of the environmental assessment, and a description of the consultations made by the developer and the results of each consultation. R.S.O. 1990, c. E.18, s. 6(2)--(3), 13.2(3); R.R.O. 1990, Reg. 334, s. 1.1.

Terms of Reference prepared ahead of a Class EA must also:

  • Indicate that the Class EA will be prepared in accordance with the requirements set out in R.S.O. 1990, c. E.18, s. 14(2);
  • Indicate that the Class EA will be prepared in accordance with such requirements as may be prescribed for the type of project to which it relates; or
  • Set out in detail the requirements for the preparation of the Class Environmental Assessment.

R.S.O. 1990, c. E.18, s. 13.2(2).

The developer must also consult with any interested persons when preparing both Terms of Reference and an Environmental Assessment (EA). R.S.O. 1990, c. E.18, s. 5.1, 13.1.

9-ON-a.33 – Provide Public Notice of Terms of Reference

If the commenter wishes for the Minister to consider the comment in deciding whether to approve the Terms of Reference, they must submit the comment by the prescribed deadline. R.S.O. 1990, c. E.18, s. 6(3.5)–(3.6), 13.2(3).

9-ON-a.35 – Refer Terms of Reference Matter(s) to Mediation (Optional)

The Minister may also refer the Terms of Reference to mediation in accordance with section 8 of the R.S.O. 1990, c. E.18. R.S.O. 1990, c. E.18, s. 6(5), 13.2(3). Deadlines may differ for Terms of Reference that are sent to mediation, and if so, are prescribed. R.S.O. 1990, c. E.18, s. 6(7), 13.2(3). The Minister can appoint one or more persons or the Ontario Environmental Review Tribunal (Tribunal) to act as mediators to resolve any disputes or concerns the Minister identifies in connection with the project. R.S.O. 1990, c. E.18, s. 8(1)–(2).

The mediation is not open to the public unless the mediators decide otherwise, and the parties to the mediation are the developer and anyone else the Minister identifies as a party. R.S.O. 1990, c. E.18, s. 8(4)–(5). The mediators must provide their decision in a report due to the Minister within 60 days of being appointed unless the Minster specifies an earlier deadline. R.S.O. 1990, c. E.18, s. 8(6)–(7). Only the Minister can make any part of the report public, and they must make the whole report public after they issue a final decision on the Terms of Reference. R.S.O. 1990, c. E.18, s. 8(8)–(9).

9-ON-a.36 to 9-ON-a.37 – Review Terms of Reference for Approval

The Minister must review the Terms of Reference for approval. The Minister must approve the Terms of Reference if they are satisfied that an EA prepared in accordance with the proposed Terms of Reference would be consistent with the purpose of the R.S.O. 1990, c.

The Minister must notify the developer, the clerk of each municipality the project affects, anyone who submitted comments on either the EA or the Ministry review of the EA, and anyone else the Minster thinks they should notify about the referral. R.S.O. 1990, c. E.18, s. 8(3), 15. Additionally, the developer must pay the fees and reasonable expenses of the mediators. R.S.O. 1990, c. E.18, s. 8(10), 15. The mediation is not open to the public unless the mediators decide otherwise, and the parties to the mediation are the developer and anyone else the Minister identifies as a party. R.S.O. 1990, c. E.18, s. 8(4)–(5), 15. The mediators must provide their decision in a report due to the Minister within 60 days of being appointed unless the Minster specifies an earlier deadline. R.S.O. 1990, c. E.18, s. 8(6)–(7), 15. Only the Minister can make any part of the report public, and they must make the whole report public after they issue a final decision on the EA. R.S.O. 1990, c.

  • The EA;
  • The Ministry review of the EA;
  • The comments submitted for both the EA and the Ministry review of the EA;
  • If applicable, the mediators’ report given to the Minister; and
  • Such other matters as the Minister considers relevant to the application.

R.S.O. 1990, c. E.18, s. 9(2), 15.

The Minister can decide an Application with approval from the Lieutenant Governor in Council in one of three ways:

  1. The Minister can give approval to proceed with the project;
  2. The Minister can refuse to give approval to proceed with the project; or
  3. The Minister can give approval to proceed with the project subject to conditions the Minister considers necessary to further the purpose of the R.S.O. 1990, c. E.18 by specifying or requiring:
    • The methods and phasing of the carrying out of the project;
    • The works or actions to prevent, mitigate or remedy effects of the project on the environment,
    • Such research, investigations, studies and monitoring programs related to the project, and reports thereof, as the Minister considers necessary,
    • Such changes in the project as the Minister considers necessary,
    • That the developer enter into one or more agreements related to the project with any person with respect to such matters as the Minister considers necessary,
    • That the developer comply with all or any of the provisions of the environmental assessment that may be incorporated by reference in the approval; or
    • The time during which the project or any part thereof shall be commenced or carried out.

R.S.O. 1990, c. E.18, s. 9(1), 15.

R.S.O. 1990, c. E.18, s. 11.1(1), 15. The Minister must give notice of the deferral, including written reasons for why the deferral is appropriate, to the developer and anyone who submitted comments to the Ministry. R.S.O. 1990, c. E.18, s. 11.1(4)–(5), 15.

Decisions made under the Ontario Environmental Assessment Act are not subject to review. R.S.O. 1990, c. E.18, s. 11.4(5).

9-ON-a.52 – Provide Notice of Decision

The Minister must notify the developer and anyone who submitted comments to the Ministry of their decision and provide the reasons for their decision to the developer. R.S.O. 1990, c. E.18, s. 9(3)–(4), 15.

9-ON-a.53 – Refer Application to Tribunal (Optional)

The Minister may refer an Application or part of an Application to the Tribunal for a decision. R.S.O. 1990, c. E.18, s. 9.1(1), 9.2(1), 15. As stated in 9.48 (Comment on Ministry Review), any person can also ask the Minister to refer an Application in part or in whole to the Tribunal, and if granted, the Minister and Tribunal follow the respective processes as though the Minister instigated the referral. R.S.O. 1990, c. E.18, s. 9.3(1), (3)–(4), 15. If the Minister refers only part of an Application to the Tribunal, then the Minister must provide notice of the referral to the developer and anyone who submitted comments on the Application and give them all information provided to the Tribunal. R.S.O. 1990, c. E.18, s. 9.2(4), 15.

If deciding on a whole Application, the Tribunal can make any of the three decision options that the Minister can make (approve, refuse, or approve with conditions; see 9.50 to 9.51), and the final decision must be consistent with the approved Terms of Reference. R.S.O. 1990, c. E.18, s. 9.1(2), (4), 15. Alternatively, if the Tribunal is only deciding some of the matters relating to the Application, it must follow any conditions imposed by the Minister on the referral and must consider the decisions the Minister plans to make on the rest of the Application. R.S.O. 1990, c. E.18, s. 9.3(2)–(3), 15. In both cases, the Tribunal must also consider the following:

  • The purpose of the R.S.O. 1990, c. E.18;
  • The approved Terms of Reference for the EA;
  • The Minister review of the EA;
  • Comments submitted on the EA and on the Ministry review of the EA; and
  • If applicable, the any public portions of the mediators' report.

R.S.O. 1990, c. E.18, s. 9.1(3), 9.2(5), 15.

The Tribunal must make its decision by the deadline the Minister sets, or by a later date if the Minister allows based on a sufficient reason (circumstances that are "unusual, urgent, or compassionate"). R.S.O. 1990, c. E.18, s. 9.1(5), 9.2(6), 15. The Tribunal can also defer deciding a matter relating to the Application if the Tribunal thinks it is appropriate because the matter is being considered in another forum, or for scientific or technical reasons. R.S.O. 1990, c. E.18, s. 11.1(2), 15. The Tribunal must give notice of the deferral, including written reasons for why the deferral is appropriate, to the developer and anyone who submitted comments to the Ministry. R.S.O. 1990, c. E.18, s. 11.1(4)–(5), 15.

The Tribunal's decision on all or part of an Application is subject to the Minister's review. R.S.O. 1990, c. E.18, s. 11.2(1)–(2), 15. Within 28 days of receiving the Tribunal's decision (or longer if the Minister chooses by order), the Minister may, with the approval of the Lieutenant Governor in Council, issue and send to anyone who received a copy of the Tribunal's decision:

  • An order varying the decision of the Tribunal;
  • An order substituting their decision for that of the Tribunal's; or
  • A notice to the Tribunal requiring the Tribunal to hold a new hearing respecting all or part of its decision.

R.S.O. 1990, c. E.18, s. 11.2(2), (4), 15.

The Minister must notify anyone who received a copy of the Tribunal's decision that the Minister has issued an order or notice affecting the Tribunal's decision or that the Minister plans to do so within a period specified in the notice. R.S.O. 1990, c. E.18, s. 11.2(3), 15. The Tribunal's decision does not go into effect until the time for the Minister to review the decision expires. R.S.O. 1990, c. E.18, s. 11.3, 15.

9-ON-a.54 – Refer Matters Relating to Application to Another Tribunal (Optional)

The Minister or the Tribunal can refer matters relating to the Application to another tribunal if it is appropriate under the circumstances. R.S.O. 1990, c. E.18, s. 11(1), (7), 15. The Minister or Tribunal can set conditions on this referral, including whether there is to be a hearing by the other tribunal, and the other tribunal's decision is considered to be a decision of the Minister or Tribunal. R.S.O. 1990, c. E.18, s. 11(3), (6), 15.
