Canada: The Canadian Gypsum Company (CGC) has temporarily closed part of its wallboard plant in Hagarsville in Ontario due to a coronavirus outbreak amongst its employees. Around half of the 250-strong workforce at the site has been sent home, according to the Norfolk & Tillsonburg News. The plant’s mine has also been closed. The company said it had acted "out of an abundance of caution" and it is working with local health services.
