What's New?

  Change to SO2 AAQC and categorization

The Ministry of the Environment, Conservation and Parks (MECP) updated the Ambient Air Quality Criteria (AAQC) for Sulphur Dioxide (SO2) to be more protective of human health. The new AAQC came into effect as of March 20, 2018 and applies to all data since that date. For more information, please visit Frequently Asked Questions.
