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.

Industrial laundry Industrial Launderers (Excel) Guide
If you use two or more calculators Calculation of Totals (Excel)

(Add the results from the output summary tables of two or more calculators in to 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)

Keep the following records and supporting documents for five years, including:

  • Calculation files
  • Summary of the amount of cleaning solvents, detergents, spot cleaning materials, softener, or other chemicals that are VOCs or contain VOCs that were used in the reporting year along with their Safety Data Sheets (SDS)
  • Number of disposed filters for the reporting year if any
  • The natural gas bills for the reporting year, if you used natural gas for drying process
  • 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.

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 to 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.
