Canada's Ontario shuts down most public venues, declares state of emergency

Ontario, Canada's most populous province, banned gatherings of more than 50 people and ordered the closure of bars and restaurants on Tuesday in a bid to slow the spread of the coronavirus.

"We must act decisively, we must not delay," Premier Doug Ford said at a news conference. "Right now we need to do everything possible to stop the spread of COVID-19 ...to avoid overwhelming the healthcare system."
