The Toyota plant in Cambridge, Ont., has had at least two people test positive for COVID-19.
On March 19, the first test came back positive and the afternoon shift was sent home.
The morning shift was still expected to work the next day; then Toyota called for a two day shut down.
During the closure, an internal email was leaked indicating that Toyota officials knew about the positive test at 4 p.m. on March 19 but continued to operate the production lines.
The company then decided to close for two days and deep clean the plant, according to employees.
After the second case was confirmed on March 25, the company announced it was shutting down the factory for a month.
Some workers are unhappy with how Toyota handled the situation and are afraid they may have been exposed to the coronavirus at work.
Toyota did not respond to requests for comment.
