The NDP is worried about the impact of U.S. tariffs on Saskatchewan steel exports.
The U.S. is set to impose a 25 percent tariff on Canadian, Mexican and Europe steel exports at midnight Thursday.
Opposition leader Ryan Meili believes the tariffs could hurt Evraz plant shipments from Regina.
Premier Scott Moe is disappointed with the U.S. tariffs and has spoken to Prime Minister Trudeau about the issue.
Moe says he will be going to Washington next week to discuss trade issues and push for a new trade agreement.
