Tam says the number of people with severe cases of COVID-19 continues to increase with a daily average of more than 1,400 people treated in hospitals over the past week.
She says that includes a daily average of 280 people in intensive care and 55 reported deaths each day in the past seven days.

Ontario recorded 1,581 new diagnoses and 20 new deaths on Saturday, while Quebec recorded 1,448 cases and 25 deaths related to the virus.
Manitoba added 237 cases to its tally, as well as multiple deaths linked to a long-term care facility in Winnipeg under provincial investigation.
