York Region Public Health has issued a public health notice after 70 COVID-19 cases were linked to one workplace in Vaughan.

The outbreak is tied to State Windows Corporation, a window design, engineering, manufacturing, and installation facility, according to the notice.

The health authority was first notified of a “cluster” of virus cases linked to the facility on November 10. They then identified 70 cases associated with the workplace, and declared an outbreak on November 20.

Eight of the confirmed cases are in residents of York Region, 33 are in residents of Peel Region, 24 are in residents of Toronto, and five cases are in residents of Simcoe-Muskoka.

York Region Public Health is conducting case management and contact tracing, and is working with the employer to identify any additional cases. They say the outbreak is considered “low risk” as the workplace is not open to the general public.

This is the second COVID-19 outbreak linked to State Windows Corporation since the start of the pandemic. The first outbreak was declared on May 17, and spread to 17 people before it was officially over on July 6.

The health authority is working with the Ministry of Labour as part of its on-going investigation.

Following an on-site inspection, York Region Public Health recommended a range of prevention measures.

State Windows Corporation has now provided face shields, individual hand sanitizer, and disinfecting wipes to workers, and begun cleaning lunchroom tables after every use.

The facility has increased its monitoring of physical distancing and introduced multi-lingual screeners to address language barriers.

The outbreak is now “showing signs of improvement,” the health authority said.
