Conservation Halton’s Administration Office is closed to the public due to the COVID-19 pandemic. This means that we will not be accepting walk-in meetings or hosting or attending external meetings. Our staff will be available to assist you by email and phone. Staff will also be able to assist with electronic planning and permit submissions. Details about what you can expect from our Planning & Regulations team are posted below.

We will keep you informed:

Staff will keep the lines of communication open and will inform you on the status of our review and your application. We will also keep you up to date if there are any changes on when our office will re-open to the public.

Conservation Halton (CH) strives to:

  • protect life and property from natural hazards such as flooding and erosion,
  • prevent environmental degradation and loss of significant natural features and their ecological and hydrological functions, and
  • prevent pollution of natural features and watercourses.

CH does this in two ways. First, CH provides planning services to provincial agencies (click here to see Niagara Escarpment map), municipalities, and landowners throughout its watersheds (click here to see Conservation Halton Watershed map). Second, under Ontario Regulation 162/06, CH regulates:

  • all development in or adjacent to river or stream valleys, wetlands, shorelines or hazardous lands;
  • alterations to a river, creek, stream or watercourse; and
  • interference with wetlands.

Permission is required from CH for undertaking any works in or adjacent to watercourses, river or stream valleys, lands adjacent or close to the shoreline for Lake Ontario, other natural hazards such as karst, and wetlands and surrounding lands where development could interfere with the hydrologic function of a wetland.


Submission Tips

  • E-mail us first – Staff is available via email, in person, video conference or phone but it is best to first connect with us over email. Please email us with any questions or if you would like to set up a time for a virtual meeting or conference call. Continue to reach out directly to your contact on the Planning & Regulations team for file specific matters. General inquiries can be directed to
  • Complete, digital submissions – Ensure that permit submissions are complete and include all required information. Digital submissions are preferred and can be made via email or for large files via our P&R drop box (see process below). CH permits and correspondence will be issued electronically via email.
  • Reduce file sizes – Given the volume of digital submissions we are currently receiving, as well as the amount of data associated with most planning or permit submissions, it would be helpful if files were compressed, where possible (i.e., reduce PDF and AutoCAD file size and create zip files). It would also be helpful to have large technical reports broken down into separate sections (i.e., main report should be separate from appendices) and larger plans/figures sent separately from reports. Please use short file names that clearly identify the file contents.
  • Prioritize files – Please let us know if there are certain files you would like us to focus our attention on. It would be helpful if you could prioritize for us your files and business-critical needs.
  • Electronic payments – Credit card or Electronic Fund Transfers (EFTs) are the preferred method of payment for both permit and planning submissions. Planning & Regulations staff can provide direction on how to make payment. We are unable to process any application without the applicable review fee.
  • P&R drop box – An electronic drop box has been set-up for large planning and permit submissions. Planning & Regulations staff will provide applicants with a link and password so that digital submissions can be uploaded to our digital drop box.
  • Planning reviews – New planning applications must be circulated to CH by our municipal partners and should not be submitted directly to CH (except electronic payment; refer to “Electronic Payments”). All review agencies should be copied on subsequent submissions to ensure that each agency is reviewing the same information. Digital submissions are preferred and should include all required information (see submission tips above).
  • Upfront technical reviews – To expedite the review, CH recommends large technical reviews are completed in advance of a formal planning or permit application being submitted (e.g., EIR/FSS, SIS). Staff can also work with landowners to identify environmental constraints/opportunities for specific sites (e.g., floodplain modelling reviews, wetland water balance assessments). Technical review fees will apply.
  • Site inspections – CH staff is available to complete site inspections. All participants must abide by the most up-to-date public health requirements (e.g., physical distancing, wearing masks). In some situations CH may consider alternative options to expedite site inspections, such as drone flyover video review and/or photos. We encourage landowners to contact staff before doing this, so that we can discuss if video footage is appropriate for the given site or works.



Conservation Authorities were formed under the terms of the Conservation Authorities Act, 1946, which was created to address natural resource issues such as deforestation, soil erosion, flooding, and degraded water quality. The Conservation Authorities Act recognizes that natural resources are best managed on a watershed basis. Click here to see a map of Conservation Halton’s watershed

Conservation Halton (Halton Region Conservation Authority) was formed in 1963 through the amalgamation of its predecessors, the Sixteen Mile Creek Conservation Authority created on December 20, 1956 and Twelve Mile Creek Conservation Authority, formed on June 12, 1958.

Since 1972, Conservation Halton (CH) has administered a regulation passed under the Conservation Authorities Act. This regulation is intended to prevent loss of life and property damage as a result of naturally-occurring hazards as well as to protect and restore the natural ecosystem in sensitive natural areas.

The current regulation administered by CH is Ontario Regulation 162/06. Through this regulation, permission from Conservation Halton is required for most works in and adjacent to:

  • watercourses
  • flood plains
  • steep slopes
  • valley lands and meander belts
  • shoreline of Lake Ontario
  • wetlands
  • hazardous lands

Regulated areas are delimited by Approximate Regulatory Limits mapping (ARL). Mapping showing the ARL is available at the Conservation Halton Administration Office at 2596 Britannia Road West, Burlington and is also available on our website, click the Online Mapping link here. Mapping for specific sites is available on request from Conservation Halton.

Refinements or adjustments to the ARL are undertaken if detailed technical studies, undertaken as part of a permit application and completed to the satisfaction of Conservation Halton staff, demonstrate that the hazard limit differs from that shown on the map.
