Canada has warned Amazon.com that it is reviewing business ties with the company’s cloud-computing unit following Amazon’s decision to shut down its warehouses in Quebec, leading to the layoff of 1,700 workers.

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

Canada’s industry minister said Amazon.com Inc.’s decision to shut down all warehouses in Quebec and cut close to 2,000 jobs would prompt the government to examine its current deals with the e-commerce and technology company.
