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.

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.
