Aggregate data about the emission of air pollutants especially those potentially harmful to human health (although it is not a requirement to include information on greenhouse gas emissions). Aggregate means national-level or available for at least three major cities. In order to satisfy the minimum requirements for this category, data must be available for the following pollutants and meet the following minimum criteria:

  • Particulate matter (PM) Levels
  • Sulphur oxides (SOx)
  • Nitrogen oxides (NOx)
  • Volatile organic compounds (VOCs)
  • Carbon monoxide (CO)
  • Updated on at least once a week.
  • Measured either at a national level by regions or at leasts in 3 big cities.

Comments

The National Pollutant Release Inventory (NPRI) is not released in a timely fashion. The preliminary, unreviewed 2012 data cannot be downloaded in bulk. The reviewed data of prior years can be downloaded in bulk. Environment Canada's website's terms of use prohibit commercial reproduction. However, data.gc.ca publishes many of the same datasets under an open license. The Meteorological Service of Canada (MSC) HTTP data server is a source of several raw meteorological data types and forecast data. This service is aimed at specialized users with good meteorological and IT knowledge, and is mainly meant to be accessed in an automatic manner via the internet (e.g. with scripts). The server's URL is: http://dd.meteo.gc.ca/. Also, in Canada provinces and territories also have monitoring sensors, data would need to be acquired from them as well.
