What are some unique challenges faced by Canadian winemakers?

Both Canadian winemakers and wine grape growers must react to the country's characteristic cold climate and relatively short summer (or grow season). Winter, hazardous weather, and springtime damage poses threats to untended vineyards and viticulturalists strive to develop novel vineyard practices and invest in frost protection system which may reduce such incidents. The Canadian winemaking industry struggles against the outflow of capital investment into more conventional industries, low brand recognition, and limited terroir. However, Canadian winemakers have become resilient and creative, making wines that show characteristics unique to their respective regions.
