Purpose of Database
OnAIR is Ontario's industrial, commercial, institutional, and municipal air emissions registry. OnAIR gives the public immediate access to information about what emissions are being released into the air and by whom.

Content
Data on annual, smog season, and quarterly emissions of contaminants from larger facilities which meet the reporting criteria. Company and facility-level data. Geolocators: postal codes, longitudinal / latitudinal coordinates. Data elements: basic facility information on the company contact, facility location, and operation and equipment; air emissions for facilities meeting the reporting criteria; mode of emission release (i.e., point or fugitive); and air emission estimation method. There are approximately 20 million records in the database.

Data coding/classification standards: North American Industrial Classification System (NAICS) Code; Chemical Abstracts Service (CAS) Registry number.

Year Database Established
2002 (April)

Coverage Period
April 2002 to present

Data Updates
Larger facilities report annual, smog season, and quarterly emissions of contaminants which exceed the reporting thresholds. In order to ensure timely, public access to emission data, this information is posted directly to a public Website by the regulated facilities. These facilities may also flow the information through the ministry for posting. Regulated facilities are accountable for the accuracy and timeliness of the data they submit.
