From now on, many companies that want to sell clothing to the Ontario government will have to provide the names of the people who made the clothing.
The names and addresses will be put onto a website so if anyone wants to check them, they can.
The new rules apply to companies selling more than $5,000 of clothing to the government.
If they do not give the information, they may not be allowed to sell the clothing.
Last year, unsafe workplaces in Asia made the news. In one incident, there was a fire in a clothing factory in Bangladesh.
It turned out that some Canadian companies were buying products from the Bangladesh factory even though it wasn’t a safe place. In other workplaces, reports came out about children in factories doing the work, which is against the law.
