The Canadian Association of Petroleum Producers says no-one wins in a trade war.

CAPP says the 10 per cent tariffs imposed on Canadian petroleum products “undermine our mutually beneficial relationship” and will increase costs for American consumers while damaging the economy on both sides of the border.

Canada ships close to 5 million barrels of oil per day to the United States.

CAPP says it’s difficult to predict how a 10 per cent tariff will affect supply, demand and trade patterns, but local producers will find the best ways to mitigate the impact.
