Canada’s Air Pollutant Emissions Inventory Report:
chapter 2

2017 Emissions and trends

This chapter describes the main sources and sectors contributing to the emissions of each pollutant and their historical trends. A description of source categories, sectors and sub-sectors is provided in Chapter 1 Table 1–1.

The contribution of each source category to total emissions of air pollutants varies by pollutant (Table 2–1), Footnote 1  as with the following examples.

  • dust is an important source of particulate matter (PM) emissions, accounting for 60% of emissions of total particulate matter (TPM) less than or equal to 2.5 microns (PM2.5)
  • agriculture accounts for most ammonia (NH3) emissions (94%)
  • incineration and Waste account for a significant proportion of hexachlorobenzene (HCB) (61%) and dioxins and furans (D/F) (37%) emissions
  • the Ore and Mineral Industries account for the largest proportion of sulphur oxides (SOx) (40%), cadmium (Cd) (67%), lead (Pb) (77%) and mercury (Hg) (42%) emissions
  • transportation and Mobile Equipment are the largest emitters of nitrogen oxides (NOx) (52%) and carbon monoxide (CO) (54%)
  • the Oil and Gas Industry is the largest emitter of volatile organic compounds (VOCs) (37%)
  • the Commercial / Residential / Institutional category is a particularly significant source of polycyclic aromatic hydrocarbons (PAHs) (90%)

A few key sources exert a relatively large influence on the emissions of several pollutants or their trends. Among industrial sources, the non-ferrous refining and smelting industry is a major source of SOx (28%), Pb (72%) and Cd (63%). Since 1990, the industry contributed significantly to the downward trends in emissions of these pollutants, as well as of emissions of Hg. Over the years, the upstream oil and gas industry has become a dominant source of VOC (35%) and NOx (26%) emissions in Canada, with increasing trends in emissions of both pollutants. In contrast, there were reductions in emissions of SOx, NOx, VOCs, HCB and Hg from coal-powered electric generation. Home firewood burning represents 90% of Canada’s PAH emissions and 21% of its CO emissions; it is also the dominant combustion source of PM2.5. While transportation and mobile equipment sources remain large contributors to NOx, VOC and CO emissions, emissions from these sources have decreased significantly since 1990.

The last year saw no significant change in the general downward trends of pollutant emissions. However it should be noted that emissions of PM2.5 and HCB have remained relatively stable since 2012, and emissions of NH3 peaked in 2004 and have since fluctuated. Emissions of SOx continued to decline, largely due to decreasing emissions from upstream oil and gas operations and coal-fired electric power generation. Improved control measures and changes in sulphur levels in fuel resulted in a decrease in PM2.5 emissions from marine transportation. Upgrades to the Rio Tinto Alcan smelter in the province of British Columbia resulted in a significant decrease in PAH emissions from the aluminium industry. Emissions of Cd have steadily declined in recent years, with reductions in emissions from several sources.

0.00 Indicates emissions truncated due to rounding

The various components of each source category contribute varying proportions of emissions of each pollutant (Table 2-2). For example, within the dust source category, road dust and construction operations are the largest sources of total PM emissions (almost five times greater than agriculture, the next most significant source). The upstream oil and gas industry is the largest emitter of VOCs. In transportation, heavy-duty diesel vehicles are significant emitters of NOx, and off-road gasoline vehicles and equipment are large contributors of CO. The subsequent sections of this chapter identify the important sources of emissions for each substance in 2017 and their varying contribution to total emissions over time.

The full time series of national, provincial, and territorial pollutant emissions from 1990 to 2017 are available through the Air Pollutant Emission Inventory Online Data Query Tool. The APEI data is also available on-line at the Government of Canada Open Data Portal website.
