Energy Production

Crude Oil

  • Ontario produced 1.0 thousand barrels per day (Mb/d) of light oil in 2016 (Figure 1). Ontario’s production represents less than 0.1% of total Canadian oil production.
  • Ontario is home to Canada’s first commercial oil production when oil was discovered near Black Creek (later renamed Oil Springs) in 1858. Large oil deposits were discovered in the 1860s in Petrolia, just north of Oil Springs.
  • All of Ontario’s oil production occurs in southwestern Ontario.

Refined Petroleum Products (RPPs)

  • Ontario has four refineries: Imperial, Suncor, and Shell in Sarnia, and Imperial in Nanticoke. These refineries have a total capacity of 417 Mb/d, which gives Ontario the 2nd largest refining capacity after Alberta and accounts for 21% of total Canadian refining capacity.
  • Western Canada supplied the majority of Ontario’s refinery demand in 2016, although United States (U.S.) imports increased in 2016 to account for 26% of total crude oil consumed by Ontario’s refineries.

Natural Gas/Natural Gas Liquids (NGLs)

  • In 2016, natural gas production in Ontario averaged 11.0 million cubic feet per day (MMcf/d) (Figure 1). Ontario’s production represented less than 1% of total Canadian natural gas production in 2016.
  • Natural gas is produced in southwestern Ontario near Sarnia.
  • There is no field production of NGLs in Ontario. Small volumes of propane and butane are produced in Ontario’s refineries.

Electricity and Renewables

  • In 2016, Ontario generated 156.0 terawatt hours (TW.h) of electricity (Figure 2), which is approximately 24% of total Canadian generation. Ontario is the 2nd largest producer of electricity in Canada and has a generating capacity of 40 215 megawatts (MW).
  • About 90% of electricity in Ontario is produced from zero-carbon emitting sources: 58% from nuclear, 23% from hydroelectricity, 8% from wind, and 2% from solar. The remaining 9% is primarily from natural gas, with some biomass and diesel. Ontario’s electricity generating capacity is primarily located in the southern portion of the province with significant hydro generating stations located in eastern Ontario in the Ottawa River basin and northeastern Ontario in the Moose River basin (Figure 3).
  • Three nuclear stations with a combined 13 500 MW of capacity provide the bulk of Ontario’s baseload generation. Bruce Power on the east shore of Lake Huron is the largest, with eight generation units and a capacity of about 6 000 MW. It is the largest nuclear power plant currently operating in the world.
  • Ontario has over 65 hydroelectricity generation facilities and a total hydroelectric capacity of
    8 872 MW.
  • Ontario leads Canada in wind capacity. About 4 826 MW of wind capacity was added between 2005 and 2016.
  • About 98% of solar capacity in Canada is installed in Ontario. In 2016, solar in Ontario had a total capacity of 2 291 MW.
  • Ontario Power Generation is the largest utility in Ontario’s competitive electricity market, with over 16 000 MW of capacity.

Energy Transportation and Trade

Crude Oil and Liquids

  • Sarnia is the major oil pipeline, petrochemical, and refinery hub in Ontario. Sarnia receives crude oil from western Canada and North Dakota via Enbridge’s Line 5 and 6B, which have capacities of 540 Mb/d and 500 Mb/d, respectively (Figure 4).
  • Enbridge’s Lines 9 and 7 run eastwards from Sarnia to supply refineries in eastern Ontario and Quebec. Line 9 has a capacity of 300 Mb/d and transports crude oil to Westover, Ontario and Montreal, Quebec. Line 7 has a capacity of 180 Mb/d and also delivers crude oil to Westover. At Westover, both pipelines interconnect with Enbridge’s Line 10 and Line 11.
  • Line 10 has a capacity of 74 Mb/d and delivers crude oil to the Union Oil refinery in Warren, Pennsylvania. Line 11 has a capacity of 117 Mb/d and supplies Imperial’s Nanticoke refinery.
  • The Trans-Northern Pipeline delivers refined petroleum products, such as gasoline and diesel, and links refineries in Montreal, Quebec with major markets and distribution centres in Ontario.
  • There are no crude-by-rail offloading facilities in Ontario.

Natural Gas

  • The TransCanada Mainline begins at the Alberta/Saskatchewan border and transports western Canadian gas through the prairies to Ontario (Figure 5).
  • The Mainline has interconnects with other pipelines at several import/export points in southern Ontario. It also connects to the Trans-Quebec and Maritimes (TQM) pipeline at the Ontario/Quebec border.
  • Historically, Ontario was a consumer of western Canadian natural gas and flowed through more natural gas to the U.S. than it imported. In recent years, Ontario has become a net importer and has increased gas imports from the U.S. Northeast and Midcontinent.
  • Dawn Hub, one of North America’s major natural gas trading hubs and pricing benchmarks, is located in Ontario. With a capacity of about 240 billion cubic feet (Bcf), Dawn is home to approximately 30% of Canada’s underground natural gas storage.
  • Ontario’s two main distribution companies are Union Gas and Enbridge Gas Distribution Inc. (EGDI). Union operates more than 69 000 kilometres (km) of main, service, and transmission lines in Ontario and serves 1.4 million customers in over 400 communities. EGDI operates more than 82 600 km of pipelines in Ontario and serves 2.1 million customers in over 100 communities. Both Union and EGDI are regulated by the Ontario Energy Board.

Liquefied Natural Gas (LNG)

  • Union Gas operates a small-scale LNG facility near Sudbury, Ontario. It has been in operation since 1968.
  • A small-scale LNG facility in Thorold, Ontario has been proposed by Northeast Midstream. The project has received local and provincial permits, and has a proposed capacity of 29.7 MMcf/d.  

Electricity

  • Most of Ontario’s electricity trade flows from north to south. Ontario’s net exports were 14.0 TW.h in 2016.
  • Hydro One owns and operates almost all of Ontario’s transmission capacity and has 29 000 km of transmission lines. There are over 70 distribution companies operating in Ontario.
  • Ontario has interconnections with Manitoba, Quebec, Michigan, Minnesota, and New York.

Energy Consumption and Greenhouse Gas (GHG) Emissions

Total Energy Consumption

  • End-use demand in Ontario was 3 050 petajoules (PJ) in 2015. The largest sector for energy demand was industrial at 35% of total demand, followed by transportation at 29%, residential at 21%, and commercial at 16% (Figure 6). Ontario’s total energy demand was the 2nd largest in Canada, and the 9th largest on a per capita basis.
  • Natural gas was the largest fuel type consumed in Ontario, accounting for 1 402 PJ, or 46%. Refined petroleum products and electricity accounted for 919 PJ (31%) and 494 PJ (16%), respectively (Figure 7).

Refined Petroleum Products (RPPs)

  • Refineries in the province produce roughly 70% of Ontario’s demand for RPPs, including gasoline. Imports are mainly from Quebec, delivered via the Trans-Northern Pipeline, rail, and truck. Imports also come from the U.S. Midwest. In 2015, roughly 16% of total Canadian RPP imports were for the Ontario market.
  • Ontario is the largest market in Canada for RPPs. Total 2016 demand in Ontario for RPPs was 607 Mb/d, or 34% of total Canadian RPP demand. Of Ontario’s total demand, 284 Mb/d was for motor gasoline and 90 Mb/d was for diesel.

Natural Gas

  • Ontario consumed an average of 2.3 billion cubic feet per day (Bcf/d) of natural gas in 2016. Ontario demand represented 28% of total Canadian demand and made it the largest consuming province after Alberta.
  • Ontario’s largest consuming sector for natural gas was the industrial sector, which consumed 1.0 Bcf/d in 2016. The residential and commercial sectors consumed 0.79 Bcf/d and 0.53 Bcf/d, respectively.

Electricity

  • In 2015, annual electricity consumption per capita in Ontario was 9.8 megawatt hours (MW.h). Ontario ranked 12th in Canada for per capita electricity consumption and consumed 32% less than the national average.
  • Ontario’s largest consuming sector for electricity in 2015 was residential at 47.9 TW.h. The commercial and industrial sectors consumed 47.1 TW.h and 41.7 TW.h, respectively. Ontario’s electricity demand has grown only 5% since 2005.

GHG Emissions

  • Ontario’s GHG emissions in 2015 were 166.2 megatonnes (MT) of carbon dioxide equivalent (CO2e). Ontario’s emissions have declined 8% since 1990.Footnote 1
  • Ontario’s emissions per capita are the 3rd lowest in Canada, at 12.0 tonnes of CO2e – 40% below the Canadian average of 20.1 tonnes per capita.
  • The largest emitting sectors in Ontario are transportation at 33% of emissions, buildings (residential and commercial) at 22%, and heavy industries (including iron, steel, and chemicals) at 12% (Figure 8).
  • Ontario’s GHG emissions from the oil and gas sector in 2015 were 10.3 MT CO2e. Of this total, 2.2 MT were attributable to production, processing, and transmission and 8.0 MT were attributable to petroleum refining and natural gas distribution.
  • In 2015, Ontario’s electricity sector emitted 5.2 MT CO2e emissions, or 7% of total Canadian GHG emissions attributable to power generation. Ontario’s GHG emissions from power generation peaked in 2000 at 42.6 MT CO2e and then saw emissions decline as it phased out coal-fired generation from 2005 to 2014.
