June 30, 2025 is the deadline for facilities to submit a report for 2024 data. Use the Registration ID (R-Code) you received in the mail. Facilities are not required to report data from 2019 to 2023. Find information including which facilities are required to or not required to submit a report, tools and calculators, a step-by-step guide to submitting your report and frequently asked questions.
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
IF
Your facility is located in Toronto
AND
You do one or more of the following activities:
Go To Step 2
You are not required to report
IF
Your facility is not located in Toronto
OR
You only do one or more of the following activities:
Go to Step 4 and submit your report as exempt to remove your facility from our database.
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.
Tips:
If you have used more than 360 L (95 gallons) of inks in a lithography process per year, then you may have reached the reporting threshold for VOCs.

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

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 | Sources | Threshold (kg/yr) | Category |
| Volatile organic compounds totals (VOCs) | Ink, cleaning material, solvents, other chemicals that contain VOCs; natural gas combustion | 100 | Released to Air |
| Benzene | Ink, ink solvents, cleaning agents | 100 | Processed, Otherwise used |
| Dichloromethane (Methylene chloride) | Waste solvent | 100 | Otherwise used |
| Formaldehyde | Ink, ink solvents | 100 | Processed, Otherwise used |
| Lead and its compounds | Ink, natural gas combustion | 10 | Processed |
| Manganese and its compounds | Ink, natural gas combustion | 10 | Processed |
| Nickel and its compounds | Ink, natural gas combustion | 100 | Processed |
| Nitrogen oxides (NOx) | Natural gas you have used to provide heat for your processes | 200 | Released to Air |
| Particulate matter 2.5 (PM2.5) | Binding, cutting, natural gas combustion | 30 | Released to Air |
| Tetrachloroethylene (Perchloroethylene) | Waste solvent | 100 | Otherwise used |
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.
Reminder: Print the confirmation page after submitting your report and keep it for five years.

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.
