The Canadian province of British Columbia--Washington state's neighbour to the north--is home to nearly three dozen wineries. In the southern part of the province, production centers on the Okanagan Valley region, where mostly white wines are produced, you can find excellent Chardonnays, Rieslings, Semillons, and Gewurtztraminers, along with the vinifera grape variety Auxerrois (well known in Alsace, France, and two vinifera 'crossings' that originated in Germany- Bacchus and Ehrenfelset.
Crossing the country, the Canadian province of Ontario--New York state's neighbour to the north--produces more wine than British Columbia, while most of it is still white as well, and much of it is from the same grape varieties. The province's specialty, however, is a type of sweet dessert wine known as ice wine. All the wines mentioned come from sturdy stock and hybrids, able to withstand Canada's cold winters.
