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. Wood Industries including pulp and paper, and furniture manufacturing.

You May Be Required to Report


Your facility is located in Toronto


If you do one or more of the following activities:

  • Wood product manufacturing (any wood product manufacturing or activities identified in Step 2)
  • Wood sawing, cutting, sanding, grinding to make wood products such as furniture and doors
  • Using one or more dust collectors
  • Making kitchen cabinets or countertops
  • Painting, using glue or any chemicals that contain volatile organic compounds (VOCs)
  • Using heat for your processes
  • Welding

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 wood related products
  • Operating a warehouse
  • Assembling components
  • Office activities

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 have used more than 111 L (29 gallons) of solvent based or 144 L (38 gallons) of water based paint or coating products per year, then you may have reached the reporting threshold for VOCs.
  • If you have used more than 125,000 cubic metres of natural gas per year to provide heat for your processes, then you may have reached the reporting threshold for NOx.

If you use two 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 five years, including:

  • Calculation files
  • Summary of the amount of paint products, glue, cleaning materials or other chemicals that contain VOCs and used in a 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
  • Summary of the amount of electrode types used and the total weight of each electrode type you used for the reporting year
  • 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.

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 your report as a below threshold facility.

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.
