Together, we grow the wines you love

Behind every glass of 100% Ontario wine is a team of 500 farm families

Grape Growers of Ontario is the official organization that represents over 500 grape growers and 18,000 acres of vineyards for processing grapes in the three Designated Viticulture Areas in Ontario: Niagara Peninsula, Lake Erie North Shore, Prince Edward County, and emerging regions such as Norfolk, Ottawa and Simcoe.

About us

For 75 years we have served as the voice and authority for our passionate and hard-working growers, and continue to endorse relevant topics of viticulture, grapes, and wine occurring in our growing industry.

We are an independent, self-governing farming organization acting under the authority of the Ontario Farm Products Marketing Act, and are funded entirely by grape growers who pay a fee per metric tonne of grapes sold. 

These funds are used to support the grape-growing system and to promote the grape and wine industry in the province.


Founded in 1947, the Ontario Grape Growers’ Marketing Board was established to represent grape growers in their dealings with processors. Now for the first time, growers were ensured of a unified, minimum price for all grapes sold to processors. Additionally, growers gained a voice in the grape and wine processing industry.

Beginning in the year 1947, there were 15,000 acres of vineyards in Ontario, and growers harvested 36,000 tons of grapes. The value of processing sales to wineries was $2.5 million. 

Today, there are over 18,000 acres of vineyards in Ontario and the kind of grapes grown is dramatically different than it was in the past. The industry has evolved and achieved its status as an internationally acclaimed grape and wine region. In the past 75 years, the farm gate value of grape sales has risen from $2.5 million to more than $100.5 million as of 2021.

Through the ever changing and growing industry, one thing, however, has not changed. We continue to represent growers, act as the voice of the industry, and lobby the government on behalf of grape-growing issues that will help growers, and strengthen co-operative ties with the winemaking industry.
