TORONTO (AP) — Ontario on Monday announced a province-wide shutdown because of a second wave of COVID-19 in Canada’s most populous province.

The lockdown will be put in place for southern Ontario from Dec. 26 until Jan. 23, but will lift for northern Ontario on Jan. 9. One top infectious disease doctor said waiting until the day after Christmas to shutdown is ridiculous.

Ontario has had seven straight days of more than 2,000 cases a day. Modeling shows that could more than double in January. Health officials earlier said a four- to six-week hard lockdown could significantly stop the spread of COVID-19.

Toronto, Canada’s largest city, had already closed restaurants for indoor dining but schools remained open. All high schools in Ontario will now be closed for in-person learning until Jan. 25. Elementary schools will be closed until Jan. 11.

After COVID-19 cases surged in the spring, Canada flattened the epidemic curve with a lockdown. But as in other countries, COVID fatigue set in, restrictions were relaxed and a second wave was unleashed.

“We have flattened the curve before and we can do it again,” Health Minister Christine Elliott said.

Dr. Barbara Yaffe, Associate Chief Medical Officer of Health, said Ontario is in a very challenging and precarious situation.

“There are outbreaks anywhere people congregate,” Yaffe said.

Ontario Premier Doug Ford said the delay until Dec. 26 will allow businesses outside the current lockdown zones to get ready for it. He said it allows restaurants a chance to sell off some of their inventory.

“I'm not comprising anything,” Ford said. “I have to be fair to these businesses who have massive inventory.”

Dr. Andrew Morris, a professor of infectious diseases at the University of Toronto and the medical director of the Antimicrobial Stewardship Program at Sinai-University Health Network, said Ford is prioritizing the economy over health by delaying.

“Ridiculous. Costing lives. For what?!" Morris said.
