The ChemTRAC program is temporarily suspended, effective May 18, 2020 and will not be able to accept annual reports or provide support to facilities.

You may use the following assessment process for ChemTRAC reporting. The Manufacturing Sector includes business activities related to Chemical and Petroleum products.


You May Be Required to Report


Your facility is located in Toronto


you do one or more of the following activities:

  • Making plastic or rubber products
  • Making furniture and related products
  • Electroplating
  • Using one or more dust collectors
  • Manufacturing parts and prefabricated products
  • Making kitchen cabinets or countertops
  • Manufacturing chemicals, painting, using glue or any chemicals that contain VOCs
  • Using heat for your processes
  • Welding and machining

Go To Step 2

You are Not Required to Report


Your facility is NOT located in Toronto


You only do one or more of the following activities:


  • Operating a store or showroom
  • Distributing products
  • Operating a warehouse
  • Assembling components
  • Operate back-up generators for your facility and you do not sell the electricity to grid line


To help you estimate the amounts you need to report to ChemTRAC, Toronto Public Health has developed calculators* that you can use. These can be opened using Microsoft Excel or a free office suite such as OpenOffice ( or LibreOffice (

These documents may not be fully AODA** compliant. For accessible formats or communication support, please contact ChemTRAC (email or call 416-338-7600).

You may download the calculators related to your business processes. If you use more than one calculator, you may use the “Calculation of Totals” calculator to add up the use and release amounts.

 If you use 2 or more calculators Calculation of Totals (Excel)

Add the results from the output summary tables of two or more calculators into this calculator to find the total amounts and identify if any chemical meets the reporting threshold)

see “Notes about the Calculators” on this page ** Accessibility for Ontarians with Disabilities Act (AODA)

You are required to keep your records and supporting documents for 5 years, including any of the following that are applicable:

  • Calculation files
  • Summary of the amount of manufactured, processed or other chemicals used that are VOCs or contain VOCs including paint products, cleaning and degreasing materials, along with their Safety Data Sheets (SDS) for the reporting year
  • Summary of electrode types and the weight of each electrode you used for the reporting year
  • The natural gas bills for the reporting year, if you used natural gas for any process heat
  • Summary of the used raw material invoices and inventory
  • Summary of the product amounts or other information that are requested in the related calculator for your estimation
  • Summary of the metal alloy types processed and the total weight of each metal alloy type processed for the reporting year, along with their Safety Data Sheets (SDS)
  • Confirmation page that you printed after submitting your report (see step 4)

Compare the results for each chemical (from the Output Summary table in the calculators) with corresponding thresholds in the appropriate reporting categories “as listed below”.

Chemical Name Sources Threshold


Particulate matter 2.5 (PM2.5) Grinding, crushing, mixing, cutting, blasting, sanding, welding, natural gas combustion 30 Released to Air
Volatile organic compounds total (VOCs) Processing or other using of chemicals that contain VOCs in manufacturing processes, using paint products, cleaning solvents, natural gas combustion 100 Released to Air
Nitrogen oxides (NOx) Natural gas fired boilers you have used to provide heat for your processes 100 Released to Air
Cadmium and its compounds Metal cutting, processing, machining, welding, natural gas combustion 1.0 Processed
Chromium, non-hexavalent, and its compounds Metal cutting, processing, machining, welding, natural gas combustion 100 Processed
Chromium hexavalent and its compounds Metal cutting, processing, machining, welding, natural gas combustion 10 Processed
Lead and its compounds Metal cutting, processing, machining, welding, natural gas combustion 10 Processed
Manganese and its compounds Metal cutting, processing, machining, welding, natural gas combustion 10 Processed
Nickel and its compounds Metal cutting, processing, machining, welding, natural gas combustion 100 Processed


For other chemicals please check the “Complete List”.

Reporting Deadline is June 30th Each Year

Submit your report if any of the amounts are equal to or exceed the reporting thresholds


if all of the amounts are below the reporting threshold, you may submit a report as a below threshold facility.

Reminder: Print the confirmation page after submitting your report.

The calculators listed above are the most current versions. It is strongly recommended to download the calculator each time you use it.

The above calculators can help you identify which priority substances (chemicals) your facility uses or releases, and estimate the amounts of these chemicals to see if you need to report to the Environmental Reporting and Disclosure Bylaw. Depending on the processes your business uses, you may need to use more than one of the calculators in Step 2 – if this is the case, you can add up the amounts using the “Calculation of Totals” calculator.

These calculators are provided solely as an aid. They may not apply to all or parts of your business operations. You can choose to use these calculators or other tools to estimate chemical use and emissions. The City of Toronto makes no representation or warranty as to the applicability of these tools to your facility or to your obligation to comply with the Environmental Reporting and Disclosure Bylaw (Municipal Code Chapter 423). It is the responsibility of each facility owner or operator to take the necessary steps to ensure compliance with the bylaw.
