Ontario

Ontario is one of Canada’s important potato producing provinces, with potatoes grown for fresh consumption, processing and seed markets. The province’s potato industry benefits from a combination of warm summer days, relatively cool nights, suitable soils and access to water. Potatoes are described by the Ontario potato industry as the province’s largest fresh vegetable crop and the second largest vegetable crop for processing after tomatoes. Production is distributed across several agricultural regions, with important growing areas in southwestern Ontario, the Niagara Peninsula, the Simcoe area and eastern Ontario.

Ontario’s growing conditions allow farmers to produce potatoes for multiple market segments. Fresh market potatoes include varieties selected for appearance, skin quality, cooking characteristics and storage performance, while processing potatoes are grown for products such as French fries and other processed foods. Ontario’s relatively long summer growing season, combined with water availability and suitable agricultural land, supports commercial potato production. The province maintains annual statistics covering planted and harvested area, yield, production, farm value and price, with official Ontario potato data available from 1984 onward.

Potato production remains an established part of Ontario’s vegetable sector and contributes to the province’s fresh-food and processing supply chains. Historical Statistics Canada data illustrate the scale of the industry: in 2004, Ontario harvested about 39,000 acres and produced approximately 7.88 million hundredweight of potatoes. By 2008, the province harvested about 35,200 acres and produced approximately 7.74 million hundredweight. Current production statistics are maintained annually by Statistics Canada and the Ontario Ministry of Agriculture, Food and Agribusiness.

Potatoes have been cultivated in Ontario for more than two centuries. Historical accounts cited by the Ontario potato industry indicate that French settlers were growing potatoes along the Detroit River, in the area extending from present day Windsor toward Amherstburg, as early as 1760. Following the arrival of United Empire Loyalists in the 1780s, potato cultivation expanded in settlements along the St. Lawrence River, Bay of Quinte and Niagara Peninsula. These early plantings established potatoes as an important food crop in the developing agricultural economy of Upper Canada.

During the nineteenth and twentieth centuries, potato production became increasingly commercialized as Ontario’s agricultural sector developed and transportation, storage and food processing infrastructure improved. Production expanded beyond household and local market use toward organized fresh and processing markets. Over time, improvements in varieties, crop management, mechanization, storage and processing helped establish the modern Ontario potato industry. Government statistics now provide a continuous historical record of Ontario potato production extending back to 1984, while the crop continues to serve both fresh and processing markets across the province.
