Canada filed a written submission in the USMCA trade dispute supporting US arguments that GM corn is safe for Mexican consumption. Canadian public interest groups, including CBAN, published a response arguing the science supports Mexico's precautionary restrictions on GM white corn used in tortillas.
The dispute keeps Mexico's restrictions on US biotech corn unresolved, adding uncertainty to a key export market for US corn, though Canada itself exports no corn to Mexico so the direct price effect is limited.
After 480 past neutral trade events, Corn moved a median +0.2% over 5 sessions (54% higher; middle half -1.1% to +1.6%), and +0.7% over 20.
