Investing.com -- Stellantis (NYSE: STLA ), the automaker, has confirmed a temporary halt in operations at its assembly plant in Windsor, Ontario. The decision comes largely due to the U.S. tariffs on imported vehicles. The shutdown will commence on Monday and is expected to last for two weeks, with operations planned to resume the week of April 21, according to reports from CBS and Bloomberg.

The company’s spokesperson, LouAnn Gosselin, stated that Stellantis is continuously evaluating the impact of the newly announced U.S. tariffs on imported vehicles. The firm will remain in discussions with the U.S. administration about these policy changes. As part of the immediate actions, the company will pause production at some of its Canadian and Mexican assembly plants. This move will affect several U.S. powertrain and stamping facilities that support these operations.

The Windsor assembly plant employs approximately 4,500 people. The plant’s shutdown was first announced by Unifor Local 444 on Wednesday through a social media post. The union indicated that more changes to the schedule are expected in the coming weeks.

According to Unifor Local 444, there were rumors of potential downtime. The company confirmed that multiple factors led to the final decision, with the primary driver being the U.S. tariffs announced by President Donald Trump. The union emphasized that this decision has created uncertainty across the entire auto industry, impacting not only their plant but also facilities in the U.S. and Mexico.

On Wednesday, President Trump announced extensive tariffs on numerous countries. While Canada was not subjected to any new tariffs, automotive tariffs announced by the president last week came into effect on Thursday. These 25% tariffs are anticipated to apply to the value of the non-American content in the vehicles. Nevertheless, parts imported under the Canada-United States-Mexico Agreement (CUSMA) are expected to remain tariff-free for the time being.
