The Economy Ontario is Canada's most productive province, generating some 40 percent of the country's Gross Domestic Product. Mining has always played an important role in the development of Ontario's economy. Many Ontario towns have at least one industry connected to forestry. Fully 87 percent of the forest land is owned by the provincial government, which licenses logging rights. The forest industry accounts for 5.8 percent of Ontario's exports.
Financial industries are also a source of prosperity.
Tourism, the province's third-largest industry, is also important to the Ontario economy.
