The latest study from researchers at Simon Fraser University shows climate change is making it more difficult for Canadian farmers to produce food.
Key problems include dwindling water supplies and increasingly erratic weather conditions.
Hot summers have created droughts in some parts of the country, while heavy rains have caused extreme flooding in others.
Warmer temperatures are also expected to increase the spread of agricultural pests.
Researchers say the resulting impact will affect not only food production, but the entire supply chain and thousands of workers in the industry.
