Canada's corporate ethics watchdog said on Tuesday it was investigating Ralph Lauren's Canada unit to probe allegations the apparel retailer's supply chain and operations in China used or benefited from the use of Uyghur forced labor.

The Canadian Ombudsperson for Responsible Enterprise (CORE) said it had published an initial assessment report after complaints filed by a coalition of 28 civil society organisations in June 2022 against the Polo shirts maker.

CORE said the report published detailed allegations the company had supply relationships with Chinese companies that use or benefit from the use of Uyghur forced labor.

A similar investigation was launched by CORE into Nike Canada in July over allegations they also have or had supply chains or operations in China identified as using or benefiting from the use of Uyghur forced labor.

In the last couple of years, several large U.S. and Canadian multinational companies have been accused of using Uyghur forced labor either directly or in their supply chains.

CORE monitors and investigates human rights abuses mainly by Canadian garment, mining and oil and gas companies operating abroad.
