ChemTRAC is restarting, and we are requesting facilities to complete a survey to update their facility information in our database.


You may use the following assessment process for ChemTRAC reporting.

You May Be Required to Report 


Your facility is located in Toronto


you do one or more of the following activities:

  • Produce food and related raw materials such as meat, dairy, and spices
  • Produce beverage
  • Produce snacks
  • Operate commercial bakeries
  • Use heat for your processes
  • Have one or more dust collectors
  • Use chemicals and cleaning agents that contain VOCs
  • Operate a restaurant or retail facility which also manufactures food or beverages for wholesale

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:

  • Operate a restaurant
  • Operate a store
  • Retail
  • Distribute products
  • Operate a warehouse
  • 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.

* 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:

  • Calculation files
  • Summary of the related raw material amounts used in the reporting year, along with their Safety Data Sheets (SDS)
  • Summary of the cleaning material amounts used or other chemicals that are VOCs or contain VOCs and used in the reporting year, along with their Safety Data Sheets (SDS)
  • Specification sheets for dust collectors to show the air flow rates and for filters to show the efficiencies if any
  • The natural gas bills for the reporting year, if you used natural gas for any process heating
  • 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.

Chemical Name Sources Threshold
Acetaldehyde Fermentation, food additives 100 Manufactured
Formaldehyde Fermentation, food additives 100 Manufactured
Chloroform (Trichloromethane) Food additive  100 Otherwise Used
Volatile organic compounds total (VOCs) Process chemicals and cleaning solvents that contain

VOCs; natural gas combustion

100 Released to Air
Particulate matter (PM2.5) Grinding, mixing, blending, other processes; natural gas combustion 30 Released to Air
Nitrogen oxides (NOx) Natural gas you have used for oven, drying, baking process or boilers to provide heat for your processes 200 Released to Air


For more 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 and keep it for 5 years.

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

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 on the list above – 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 or all or parts of your business operations. You can choose to use these calculators or other tools that may be applicable 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.
