Development Engineering Review Service


Halton Region's role in development review

Halton Region reviews development proposals that need changes to Regional Official Plan policies or require a Regional Official Plan Amendment. In some cases, the Region will also review development applications that affect Local Official Plans and/or Zoning By-laws and those which require Site Plan Approval.

If you are a non-residential developer or business looking to capitalize on a potential opportunity in Halton Region, you can connect with our Employment Land Concierge. The concierge is here to help you navigate the industrial and commercial development approvals process.

If you need to submit a development application to a Local Municipality, the Niagara Escarpment Commission or the Ministry of Municipal Affairs and Housing, please see the Development Contacts tab below.

How does the Region review development applications?

When Regional staff review and comment on development applications, we are interested in:

  • maintaining Provincial Land Use policy interests identified in Provincial Policy Statement, Greenbelt Plan, A Place to Grow: Growth Plan for the Greater Golden Horseshoe (external link) and Niagara Escarpment Plan (external PDF);
  • ensuring development aligns with the Regional Official Plan (ROP) and supplemental ROP Guidelines;
  • coordination and allocation of municipal infrastructure, including roads, water supply and wastewater services;
  • preservation and protection of clean water, air and the Region’s Natural Heritage System, including forested areas;
  • site contamination; and,
  • collaboration with relevant Provincial ministries, Local Municipalities and Conservation authorities (Conservation Halton, Grand River Conservation Authority and Credit Valley Conservation Authority).

Development process: Preparing your submission

The drop-down sections below provide more information to help guide you through the stages of a development proposal. These stages will vary based on the type, location and size of your application.

Planning applications

Pre-consultation meeting

Pre-consultation meetings are an important first step in the development application process. They provide land owners the opportunity to discuss their development proposal with Local, Regional and Conservation Authority staff directly. Applications may be for a(n):

  • Official Plan Amendment
  • Zoning By-law Amendment
  • Draft Plan of Subdivision
  • Draft Plan of Condominium
  • Site Plan Approval

Applications must follow the pre-consultation process implemented by each Local Municipality.

To arrange a pre-consultation meeting, contact the relevant Local Municipality directly (please see the Development Contacts tab).

Regional Official Plan Amendments

Regional Official Plan Amendments must be approved by Halton Region. To learn more about the Regional Official Plan Amendment (ROPA) process, including the ROPA application form (PDF file), you can visit the Regional Official Plan Amendments and Amendment Process page.

Preparing your development application:

When preparing your development applications, please review the following resources:

Once you have reviewed the documents and prepared the studies noted in your pre-consultation form, you can submit your application to the relevant Local Municipality to be reviewed for conditional approval.

If you require any of these files in an alternate format, please email or call 311, TTY: 905 827-9833.

Regional development approval

If your application for Site Plan Approval, Draft Plan of Subdivision or Draft Plan of Condominium has received conditional approval from a Local Municipality, you will then need to meet certain conditions to receive clearance from Halton Region to proceed with development. Once all Regional conditions have been addressed, Regional staff will advise the relevant Local Municipality.

The information below can help guide you through how to clear some common Regional development conditions:

Services Permits

For any development work involving connections to water, wastewater services or Regional roads, you will need to apply for a Services Permit from Halton Region. Please consult our Permits page for more information.

Land Owner Dedication Form

Through the mandatory pre-consultation process, land owners may need to dedicate land to Halton Region under development applications. As part of this process, they must complete the Land Owner Dedication Form (PDF file). This form should include all referenced attachments, reference plans and fees. Note: Fees are reviewed and updated annually.

Phase One Environmental Site Assessment (ESA) and Phase Two ESA

The review of an Environmental Site Screening Questionnaire that contamination or potential for contamination exists. In this case, the Region will need a qualified person to indicate whether the environmental condition of the site is suitable for its proposed land use through a Phase One ESA. The Phase One ESA results will determine whether a Phase Two ESA needs to be completed. A Phase One ESA and Phase Two ESA must be completed prior to any approval, servicing or grading of the site; they also need to be prepared to O.Reg 153/04 standards, to the satisfaction of Halton Region. The author of these environmental reports must extend third-party reliance to the Region.

We are here to help. If you have any questions about how to clear Regional conditions, please call 311 and ask to speak to the Community Planning department.

Before you submit (Development Engineering Review)

Review your Planning Act development application comments and approval to determine if an engineering submission is a requirement.

Please note, in some limited circumstances, there may be the requirement for an engineering submission even when a Planning Act application is not required. In these cases, please contact Regional staff at in advance of creating an engineering file to discuss your submission and the appropriate pre-submission requirements.

Before you start a new project, please review the Region’ s standards and requirements as well as the Region’s Development Engineering Review Manual, known as the DERM (available under Submission Requirements, Templates, Reference Documents and Forms), which contains detailed information on standards, requirements, policies, manuals and by-laws. Please also ensure you are working with a reputable engineering consultant on your submission.

All engineering drawings must be prepared according to the Region’s standards. All of the proposed and existing infrastructure must be shown on the applicable drawings. Failure to adhere to Regional standards will result in additional processing time for your submissions.

When creating an engineering file, you may identify other contacts that will need to access the submission, monitor its progress or upload related documents. Some examples may be the consulting engineer, developer, land owner or a lawyer. Please ensure you have appropriate contact information for these parties so that you can add them to your Engineering file.

You should be aware of the Halton Region’s Development Engineering Review Process (PDF file), fees related to engineering submissions and how to pay them as they are part of the requirements for a complete submission. Please ensure your fees are paid prior to creating an engineering file through our online intake system.

The first installment of the Engineering and Inspection Fee must be paid prior to the first Engineering Submission. More information is available in the Region’s Development Application Requirements and Fee Schedule (PDF file).

If you require any of these files in an alternate format, please email or call 311, TTY: 905 827-9833.

Different forms, drawings, checklists and other documents are required depending on the type of engineering submission. Access templates and learn about the specific drawings and documents you have to provide under Submission Requirements, Templates, Reference Documents and Forms.

It is strongly recommended that you contact Regional staff before you submit your package if you have any questions or to discuss your submission to ensure efficient processing. Please feel free to contact Regional staff at

Depending on the type of project you’re working on and where your property is located, you may need a Regional servicing or subdivision agreement or other permits as part of your overall development approvals and processing.

Common examples of additional approvals, include:

  • Conservation authority approval for property located on land that’s regulated by a conservation authority, such as Credit Valley Conservation Authority, Conservation Halton or Grand River Conservation Authority.
  • Coordination with local municipal approvals or permits. Please visit Town of Oakville, Town of Halton Hills, City of Burlington and Town of Milton for additional information.
  • Ontario Ministry of Transportation approval for property that falls within MTO controlled areas (external link).
  • Regional subdivision or servicing agreement and/or regional permit.
  • MECP approvals.

Please do not submit subsequent submissions until you have received comments on the current submission and have addressed those comments. Submission of new drawings and documents before receiving direction from the Regional Staff member assigned to you and without addressing all of the identified items in your submission will result in delays to the processing of your submission and may result in subsequent submissions being rejected.

All and every effort should be made to adhere to Regional standards, guidelines and requirements. The Region will only consider deviations from standards when all reasonable and practical efforts have been made and explored to meet standards and requirements.

  • Deviation from Regional Standards Application (please see Submission Requirements, Templates, Reference Documents and Forms) should be submitted as early in the process as possible to ensure appropriate time for staff to consider the deviation.
  • Deviations requested that cannot demonstrate that every effort has been made to achieve the Region standards will not be considered.
  • Deviations proposed at the end stages of the review process will add additional time to the review and granting of approvals.

MECP approvals require the submission of a Design Checklist at first submission. They also require the submission of a complete MECP Approvals Package when advised by the Regional staff member assigned to your file that your drawings have advanced to a level appropriate for the review of MECP materials. Please review the design checklist and details around approval package requirements in advance. To view these forms, please refer to Submission Requirements, Templates, Reference Documents and Forms.

There are limited circumstances in which a direct submission to the MECP is required, in these cases, the Regional staff member assigned to your file will work with you to ensure the required information and forms are completed for Regional submission. 

For submissions requiring agreements with Halton Region please note that the Development Agreement Request Form (DARF) will not be accepted until you have been advised by the Regional staff member assigned to your file that your drawings have advanced to a level appropriate for the review of agreement materials. To view the DARF, please refer to Submission Requirements, Templates, Reference Documents and Forms.

Please review the Complete Engineering Submission Checklist and the Development Engineering Review Manual (DERM) below. These two documents contain all of the relevant information related to engineering submissions and the review and approval process at Halton Region. All of the common forms and templates that are referenced in the Complete Engineering Submission Checklist are also available below. Alternatively, you can email for copies of any of these documents.

If you require any of these files in an alternate format, please email or call 311, TTY: 905 827-9833.

Development Engineering Review Service

Through email money transfer or Electronic Funds Transfer, submit your engineering review fee. You will be required to upload proof of payment/receipt with your other engineering documents before the submission will be considered complete and processed. Please refer to the Paying Your Application Fee section of this page for detailed instructions on fee payments. It is important you include identifiers with your fee such as “engineering review,” your “planning file number” and “site location”.

Start the process by selecting “Sign-up ” to create an account. You will receive an email confirming your email address and a link will be provided to create a secure password. The initial information process includes the function to add other contacts who may need to review the engineering file as it moves through the process. Contacts can upload documents relevant to the file you are adding them to. They will receive an email inviting them to the file and requesting they set up their own login information. Added contacts will only be able to view the file you add them to, they will not be able to view other files within your account unless they are specifically added.

Select “Start a new Engineering File”, log in if prompted, and follow the prompts on each page to complete the required information, and if needed, the optional information. Select the “next” at the bottom right of the screen to move through the process.

Once you have completed the basic information portion of your Engineering File you will move to the document upload portion of the submission. You must then upload drawings and supporting documents, including proof of payment/receipt of the Engineering and Inspection fee non-refundable deposit required with the first engineering submission.

Make sure you provide all of the required information as noted in the complete submission checklist. It’s important to complete this step because submissions with missing documentation may result in delays.

To categorize your documents please ensure that the documents you are uploading have descriptive names and are categorized as indicated on the Complete Engineering Submission Checklist.

Note: You can upload 1 to 10 documents at a time, with a maximum of 50 documents per block. To add more documents, select Add and another block will be added for additional uploads. The maximum size per document is 10 MB and allowed document types are:

  • .pdf
  • .xlsx
  • .docx
  • .shp
  • .shx
  • .dbf
  • .mdg
  • .dwg
  • .dxf

Once you select the submit command a transaction number and a development engineering file number will be generated. This will also be sent to your email. You will have the same development engineering file number for all submissions until the file is closed.

After you upload your drawings and documents, the Region will start the prescreen review process to ensure the minimum requirements are met. The time frame for this step is subject to change depending on request volumes.

If the submission requires more information, you will be notified by email with details about the prescreen corrections. You must complete all prescreen corrections in order to move ahead with the process and for your submission to enter the “In Review” status.

Your application will then be assigned to a Regional staff member for processing and will move through the review stages by the relevant review groups to make sure it meets the required Regional standards to move towards approvals.

When the review is completed by each review group, comments will be provided to you through the staff member assigned to your Engineering file. They will indicate revisions, corrections and/or additional documentation required for your next submission. Comments will also direct you as to when the Region will accept items such as your Development Agreement Request Package (DARF) or your MECP Approval Documents, if applicable.

Regional comments will provide you with details on what you need to do next. Please keep in mind, the quality of information and detail provided in each submission will greatly impact review and processing times. You may also request conversation and explanation of comments regarding your engineering file at any time by contacting your assigned staff member directly or by emailing

Once an Engineering File has been submitted it will be shown in the “view status/upload additional documents” section of Halton Region’s Development Review Service site. There are four main statuses for submissions:

  • Submitted – An engineering file has been created and documents associated with that file have been submitted. The file will remain in this status until such time as the triage and pre-screen review has been completed to ensure all of the documents have been received.
  • In Review – An engineering file will move to this status when internal circulation and review is occurring.
  • Waiting on Customer – An engineering file will move to this status when Regional staff have provided correspondence that additional information is required to complete the submission, or when Regional staff have provided formal comments indicating requirements for the next stage. For example, comments have been issued and a subsequent submission is required, or approvals have been granted and there is the requirement for as constructed drawings.
  • Closed – An Engineering File will move to this status once all as-constructed/approved drawings have been received by the Region.

Your Engineering file will require approved drawings and MECP approvals as components of the overall approval. There may also be requirements for a Regional Subdivision or Servicing Agreement that coincides with your engineering submission. You will be notified by your assigned Regional staff member as each of these components is approved. When your agreement is ready for review, you will be contacted by the Region’s Legal Services Department. Execution of Agreements occurs at registration for subdivisions and once certain requirements under the Servicing Agreement are fulfilled for servicing agreements, and among other things requires the posting of all necessary securities.

After your agreement is executed and certain requirements under the Agreement are complete along with engineering approvals, you are ready to begin pre-construction/construction. At this point, you will move into the pre-construction and construction process. You will continue to have regular contact with your assigned staff member for your engineering file as well as other Regional staff members such as Regional Inspectors.

Your file will remain open until the submission of as-constructed drawings is complete at which point your file will be marked closed. At this time, you will receive notification it has been closed.

Agreements and pre-servicing

Preparing your Development Agreements

Once you have conditional approval on your application from a Local Municipality and have cleared Regional conditions, you can prepare a Development Agreement. Development Agreements between the applicant and Halton Region include design and construction requirements, as well as costs to build new watermains, wastewater mains and other Regional infrastructure.

A number of standard components need to be provided prior to preparing a Development Agreement. The Development Agreement Request Form (PDF file) describes these requirements and helps ensure you have included all necessary documents.

The following is a list of sample templates to help you prepare your agreement:

  • Schedule 5: This provides a sample format for a typical letter of credit and a list of acceptable financial institutions that can provide letters of credit
  • Certificate of Insurance: This provides a sample format for a typical Developer’s Certificate of Insurance

These templates are available upon request. Please email or call 311 to request a copy of the template.


Once you have submitted your Agreement Request Package to Halton Region, you will generally receive the agreement in about 15 business days. To clarify requirements, please check the Development Agreement Request Form above.

Costs payable

At the Subdivision Agreement Stage, the developer is required to provide a certified cheque to cover:

  • the engineering and inspection fees (this is based on a sliding scale, directly tied to the cost of construction);
  • water meter installation fees;
  • water and wastewater tapping fees (if applicable);
  • legal administration fees;
  • general administration fees;
  • the water, wastewater and roads components of the Region's development charge; and
  • the applicable Harmonized Sales Tax (HST).

Note: In some cases, there may be other charges.

Once a building permit is issued, the developer is required to pay the remainder of the Region-wide components (General Services) of the Region's development charge.

Note: A Development Charge Agreement may be required to collect Regional development charges before these two stages. Please check for the most current development charges information.

Service and engineering fees

Engineering and inspection fees are calculated as a percentage of the estimated cost of Regional water and wastewater services. Fees are based on a sliding scale.

Total estimated cost of proposed water services, wastewater services and road works Engineering and inspections fee deposits*
up to $100,000 $5,000 or 10% (whichever is greater) +HST
between $100,000.01 and $250,000 7% +HST
between $250,000.01 and $500,000 6% +HST
$500,000.01 or more 5% +HST (To a maximum of $100, 000 + HST)

*The first $5,000 + $650 HST = $5,650 of the total engineering and inspection fee must be submitted at the time of the first engineering drawing submission, with the balance payable upon execution of the Development Agreement.

Note: Any portion of the engineering and inspection fee collected, including the $5,000 payment, is considered a one-time charge that is non-refundable.

What is pre-servicing

There are two definitions of pre-servicing:

  1. Pre-servicing, as it relates to the agreements, is defined as servicing prior to registration. This is authorized.
  2. Pre-servicing, as understood by developers, consultants and contractors, is defined as servicing that begins prior to the execution of the agreement by a letter of undertaking or some other means. This is not allowed in Halton.

Commencing work

The developer’s contractor can start the work when the Region has received the following items:

  1. An original insurance certificate:
    • naming the Region as an additional insured;
    • showing the date and file number of the agreement; and
    • in the name of the persons entering into the agreement.
  2. A certified cheque for the amount shown in the Development Agreement.
  3. A letter of credit (as per the Development Agreement):
    • in the form, and with a banking institution, acceptable to the Region;
    • showing the date and file number of the agreement; and
    • in the name of the persons entering into the agreement.
  4. An up-to-date certified copy of the parcel page, together with postponements to all mortgages on title.
  5. Return of three copies of the agreement:
    • signed by authorized signing authorities, showing names and titles;
    • sealed (corporate seal and company name must be identical) and, if there is no seal, the signatures must be witnessed;
    • the date and place of signing must be complete; and
    • each page must be initialed by signatories.
  6. Certificate of approval issued by MECP.
  7. Fees paid.
  8. Design drawings signed.
  9. A Regional inspection must have been arranged through your development coordinator (Please allow 10 days of advance notice).
