<h1>Leader urges revival of cancelled cross-border crude pipeline linking restart to metal export tariffs, risking legal and regulatory battles</h1> A national leader raised reviving a previously cancelled cross-border crude pipeline with the US president during a bilateral meeting, linking potential energy cooperation to tariffs on metal exports. The project's permit was revoked by a prior administration on environmental and climate grounds, and the private developer abandoned it thereafter; revival would require re-issuance of border permits, federal regulatory approvals, and likely litigation or administrative review given prior rejection. The discussion signals possible political pressure to restart permitting and coordination between trade and energy policy, while affected provinces, pipeline owners and environmental stakeholders could pursue legal and regulatory challenges.
