Approximately four-fifths of Ontario's GDP is composed of service sector industries. The remaining one fifth is the goods sector. More than half of the goods sector is manufacturing. One-third is the construction sector, and a tenth is the utility sector.
High tech The province has a large technology sector, with one of North America's largest concentration of technology companies. Large Tech hubs exist in
Ottawa,
Toronto,
Markham and
Waterloo.
Agriculture The number of Ontario residents living on farms has been steadily declining for decades. In 2016 Ontario's farm population was 160,415, or 1.2 percent of the Ontario population. By way of contrast, in 1931, 800,960 Ontarians lived on farms. The decline in farm population is partly driven by consolidation of the agricultural industry. There are fewer farms than in the past: The 2016 Census of Agriculture indicates that the number of
farms declined 4.5% between 2011 and 2016 and, as of 2016, stands at 49,600 farms. However the average size of these farms is increasing. The average Ontario farm size was in 2016, up 0.2% from 2011. Since 1981, the average farm size has increased by 27.3% from . The province has lost 300,000 manufacturing jobs in the ten years 2003–2013.
Energy The
Green Energy and Green Economy Act, 2009 (GEGEA), takes a two-pronged approach to creating a
renewable-energy economy. The first is to bring more
renewable energy sources to the province and the second is the creation of more
energy efficiency measures to help
conserve energy. The bill would also appoint a Renewable Energy Facilitator to provide one-window assistance and support to project developers in order to facilitate project approvals. The approvals process for transmission projects would also be
streamlined and for the first time in Ontario, the bill would enact standards for renewable energy projects. Homeowners would have access to incentives to develop small-scale renewables such as low- or no-interest
loans to finance the capital cost of renewable energy generating facilities like solar panels. Solar panels are also manufactured in Ontario.
Mining Hard-rock mining has taken place in the province for over 140 years (as of 2022). The mining industry in Ontario produces more than 30 different metal and non-metal mineral products, and is responsible for a major percentage of Canada's
nickel,
gold,
copper and
platinum-group metals production. The extraction of metallic minerals is concentrated in Northern Ontario, while the southern portion of the province produces
salt,
gypsum,
lime,
nepheline syenite and structural materials (
sand,
gravel, stone), along with some
petroleum. As of 2014, the mining industry produced about $11 billion worth of minerals. Derisory fees are charged by the government for prospecting licences ($25.50) and exploration permits (nil), in keeping with the duty of economic development of the province. The exploration permit process is meant as a means to notify interested parties, such as surface landowners, of the activities of miners. == Infrastructure ==
