The U.S. Department of Justice pauses cooperation with Canadian government officials on antitrust matters, according to a Wall Street Journal report cited by multiple outlets. The pause affects how the U.S. and Canada coordinate on competition and enforcement issues.

The reporting links the move to broader U.S.-Canada trade tensions, suggesting the change in antitrust coordination comes amid strained economic relations between the two countries. Different outlets frame the development mainly through its connection to those trade disputes, while describing the underlying fact as a departmental pause in working with Canadian counterparts.

Both sources characterize the development as a practical shift in cross-border antitrust engagement rather than detailing specific cases. Neither source provides additional information in the provided text about the scope of the pause, whether it is temporary, or how enforcement actions might be affected. The situation is presented as part of evolving bilateral cooperation in regulatory and trade-related areas.
