Canada's House of Commons has a written question asking the government for its estimates of the economic impact of China's 76% tariff on canola seed and 100% tariffs on canola oil, meal and peas. The question asks for breakdowns overall, for canola farmers, and for the Prairie provinces.
Official impact estimates would show how deeply China's tariffs cut Canadian canola returns, which affects how much canola meal and oil reaches world feed markets. Until Canadian exports recover, the tariffs keep Canadian canola meal supply tighter in other markets.
