POLICY WIRE — Washington, DC — The antitrust division of the U.S. Department of Justice has been ordered to suspend all collaborative efforts with the Canadian government.

The directive, which was issued earlier this week, was revealed in a Friday report by The Wall Street Journal.

According to emails reviewed by the Journal, officials were told to cease working with Canadian authorities on both policy matters and active cases.

One specific email was titled Pause on Canada, though the communication did not provide a formal reason for the sudden stop in cooperation.

The move comes as a trade conflict between Washington and Ottawa continues to intensify.
