Canada is also one of the world’s largest suppliers of agricultural products, particularly of wheat and other grains. Canada is a major exporter of agricultural products, to the United States and Asia. As with all other developed nations the proportion of the population and GDP devoted to agriculture fell dramatically over the 20th century.

As with other developed nations, the Canadian agriculture industry receives significant government subsidies and supports. However, Canada has been a strong supporter of reducing market influencing subsidies through the World Trade Organization. In 2000, Canada spent approximately CDN$4.6 billion on supports for the industry. Of this, $2.32 billion was classified under the WTO designation of “green box” support, meaning it did not directly influence the market, such as money for research or disaster relief. All but $848.2 million were subsidies worth less than 5% of the value of the crops they were provided for.
