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.

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,

The closing sites span Lachine, Longueuil, Coteau-du-Lac and Laval, and include one fulfilment centre, two sorting centres, three delivery stations and a facility Amazon dubs AMXL because it aids in the shipment of large goods like TVs or furniture.

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.

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 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.
