A protest against the mass layoffs of thousands of people is underway at the Amazon warehouse in Laval Wednesday morning. Protesters are showing their support for the more than 4,600 Quebecers who will be out of work after Amazon announced it was closing seven warehouses in the province.

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.

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

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.

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.
