Amazon.com Inc.’s decision to close all seven of its warehouses in the Canadian province of Quebec and terminate more than 1,900 workers is prompting legal action from the affected union.

A union that represents some Montreal Amazon workers said it will petition a court to compel the company to reopen the warehouses and reverse the job cuts.

After Amazon announced it would shutter its Quebec warehouses, costing 1,700 workers their jobs, a Canadian union said it would strike back.

Amazon is facing growing backlash in Quebec following its January 2025 decision to shutter all seven of its warehouses in the province. The closures, set to unfold over the next two months, will eliminate approximately 4,500 jobs, including full-time positions and subcontractors.

In addition to the roughly 2,000 employees laid off by Amazon after the company announced it would be closing its Quebec warehouses, more than 2,500 other people employed by smaller carriers subcontracted by the company have also lost their jobs.

Canada has warned Amazon.com that it is reviewing business ties with the company’s cloud-computing unit following Amazon’s decision to shut down its warehouses in Quebec, leading to the layoff of 1,700 workers.

A Quebec labour group is urging governments and the public to boycott Amazon because the online retail giant announced the closure of its seven warehouses in the province a few months after workers at one of the facilities voted to unionize.
