China has launched an anti-dumping investigation into Canadian canola imports following Canada's imposition of tariffs on Chinese electric vehicles, steel, and aluminum. This move could potentially result in a 'billion-dollar hit' for Canada's canola industry, affecting trade flows and grain handlers significantly. China accuses Canada of dumping canola and causing losses to its domestic industries. Canada, following similar actions by the U.S. and the EU, imposed a 100% tariff on Chinese EVs and a 25% tariff on steel and aluminum to protect domestic jobs and industries. Farmers in regions like Alberta are already feeling the impact with a drop in canola prices. The dispute may escalate to the World Trade Organization as China plans to challenge the tariffs.
