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 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.

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.
