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.

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.

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

Amazon has announced it’s closing seven facilities in Quebec, Canada, and laying off 1,700 workers. The move comes less than a year after employees at one of the warehouses unionized and were working toward their first contract.

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.

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.
