OTTAWA — Prime Minister Mark Carney’s government is facing a new political test as Canada’s escalating trade confrontation with the United States becomes a central issue in federal politics.

Ottawa has moved to impose targeted retaliatory tariffs on more than 700 U.S. products, with the measures scheduled to take effect September 8. The federal government says the response is designed to defend Canadian economic interests while limiting damage to domestic businesses and consumers.

The political stakes are rising alongside the economic dispute. Opposition Conservatives are pressing the government over its approach to Washington, while provincial leaders are also calling for stronger measures as businesses prepare for potential disruption.

Ontario Premier Doug Ford has taken a particularly forceful position, arguing that Canada should be prepared to use its economic leverage if pressure from Washington continues. His stance adds another political dimension to Carney’s efforts to balance retaliation with negotiations.

The dispute has also become increasingly connected to questions of Canadian sovereignty and economic independence, with Carney rejecting U.S. demands that Ottawa says would compromise key Canadian interests.

The coming weeks could prove crucial for Carney as his government attempts to maintain political support at home while keeping the door open for renewed negotiations with Washington.
