Registration for ChemTRAC reporting workshops is free and strongly recommended, especially for facilities that are new to ChemTRAC.
You can use the following assessment process for ChemTRAC reporting.
You may be required to report

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 (chemtrac@toronto.ca or 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.

You are required to keep your records and supporting documents for five years, including:
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 | Source |
Threshold (kg/yr) |
Category |
| Volatile organic compounds total (VOCS) | Paint products, cleaning and degreasing solvents, other chemicals that contain VOCs | 100 | Release to Air |
| Particulate matter (PM2.5) | Sanding and preparation station, welding, natural gas combustion | 30 | Released to Air |
| Chromium, non-hexavalent, and its compounds | Welding, natural gas combustion | 100 | Processed |
| Chromium, hexavalent, and its compounds | Welding, natural gas combustion | 10 | Processed |
| Lead and its compounds | Welding, natural gas combustion | 10 | Processed |
| Manganese and its compounds | Welding, natural gas combustion | 10 | Processed |
| Nickel and its compounds | Welding, natural gas combustion | 10 | Processed |
| Nitrogen oxides (NOx) | Natural gas fired boilers if you have used it to provide heat for your processes | 200 | Released to Air |
See the full list of priority substances (chemicals).
The reporting deadline is June 30th each year.
Submit your report if any of the amounts are equal to or exceed the reporting thresholds
OR
If all of the amounts are below the reporting threshold, you may submit a report as a
below threshold facility .
Use the ChemTRAC Guide to Reporting for step-by-step instructions on 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.
