Sen. Bernie Moreno says he will introduce bill to sanction Canada over U.S. wildfire smoke

Sen. Bernie Moreno (R-Ohio) said he will introduce legislation next week to impose sanctions on Canada and on “responsible Canadian government officials” in response to large wildfires that have generated smoke and haze across the United States. Moreno made the announcement Thursday, framing the proposal around air-quality hazards affecting Americans.

According to Moreno, the bill will target Canada’s government and officials whom he says are responsible for addressing wildfire conditions that are producing hazardous smoke. He did not specify in the announcement what form the sanctions would take or what legal mechanism the proposal would use, other than stating that it would seek to punish Canada for the ongoing emissions affecting the United States.

The move comes amid heightened attention to wildfire-related air pollution as smoke drifts across state lines and into major population centers, prompting public health concerns and restrictions on outdoor activity. Moreno’s stated rationale, as described in his remarks, is that the Canadian government should take steps to mitigate the impacts of its wildfire conditions on the United States.

Moreno, who has aligned closely with President Donald Trump, positioned the legislation as an enforcement tool rather than a voluntary diplomatic response. The announced timeline, he said, would be followed by introduction “next week,” giving lawmakers a defined starting point for consideration.

The proposal also highlights a broader question of how far Congress can go in responding to cross-border environmental impacts through economic and regulatory restrictions. Sanctions legislation often requires careful drafting regarding targeted entities, due process, waiver authorities, and reporting obligations to Congress, particularly when applied to government officials.

A key next step will be the bill’s formal text, including which Canadian entities and officials would be covered, what triggers would determine eligibility for sanctions, and whether the bill would direct executive-branch implementation through an existing authority or create a new one. Moreno’s announcement did not include those specifics, so the scope of potential penalties remains to be seen.

If introduced, the bill would be expected to move through committee review and floor consideration, with any final action depending on negotiations over enforcement details, national security and foreign policy coordination, and the practical effects on U.S. interests. Moreno’s office has not indicated whether the legislation would include carve-outs, specific timelines, or conditions for lifting any sanctions.
