US Lawmakers Criticise Trump Tariffs After Canada Talks Collapse
The United States and Canada tried to make a trade deal but did not agree.
The United States then placed 50% taxes, called tariffs, on some Canadian goods.
Canada said it would place similar taxes on American goods.
Lawmakers in both parties warned that this could make products more expensive.
They also said companies and farmers that depend on cross-border trade could face problems.
Canada’s prime minister said the United States had made unfair demands.
The United States trade representative said Canada changed or withdrew earlier promises.
Some US lawmakers want Congress to have more power to review presidential tariffs.
US tariffs of 50% on various Canadian products took effect after trade talks failed.
Canada plans matching duties and additional support for affected workers and companies.
Lawmakers warned the tariffs could raise prices, disrupt supply chains and hurt border businesses.
Canadian Prime Minister Mark Carney said the United States demanded too much and offered too little.
US Trade Representative Jamieson Greer blamed Canada, while lawmakers renewed calls for congressional review of tariffs.

Neal accused President Donald Trump of changing his demands at the last minute and undermining negotiations with a close ally.

Authority over tariffs
Critics of the tariffs
Collins and Welch support measures to restore Congress’s authority to review major tariff decisions and want an off-ramp from the confrontation.

The administration has used presidential tariff authority, while the articles do not specify a separate congressional defence of that authority.
