A Canadian union that successfully unionized one warehouse accused the company of closing its sites to fend off organizing efforts in the region.

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.

Amazon.com Inc. will shut down all warehouses and lay off employees in the French-speaking Canadian province of Quebec. The decision comes less than a year after workers at one of those facilities unionized.

The online retail giant said the move was not linked to recent unionization efforts by workers in the Canadian province.
