Ontario wine is Canadian wine produced in the province of Ontario. The provinces has three official wine-growing region, the Niagara Peninsula, the north shore of Lake Erie, and Prince Edward County, although wineries also exist in other regions in Ontario. Approximately two-thirds of Canada's vineyard acreage is situated in Ontario, with over 150 vineyards spread across . As a result, the province is the country's largest producer of wine, accounting for 62 per cent of Canadian wine production, and 68 per cent of all Canadian wine exports. The province is home to Canada's first commercial winery, opened on Pelee Island in 1866. Wineries based in Ontario began to produce ice wine in the early 1980s. In 1999, the Legislative Assembly of Ontario named the Vintners Quality Alliance (VQA) of Ontario as the province's official wine authority.
