A company spokesperson said Amazon will outsource deliveries to smaller contractors. The spokesperson insisted that the decision was tied to cost savings — not the recent unionization of about 300 employees at the Laval,

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.

Unions had gained a foothold in one of the company’s warehouses in the province, though Amazon would not say if there was a connection.

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.

E-commerce giant Amazon.com is exiting its operations in Quebec, leading to the loss of about 1,700 full-time jobs, a company spokesperson said on Wednesday. The online retailer will phase out operations across seven sites in the province—the only location in Canada with unionized Amazon employees —over the next two months.

The Confédération des syndicats nationaux (CSN) is accusing Amazon of closing its Quebec facilities because workers at its Laval, Que., warehouse unionized. The union is now planning legal action against Amazon and asking Quebecers to boycott the company.
