TORONTO -- Health officials are reporting more than 600 new cases of COVID-19 on Monday morning as the province’s testing strategy shifts from walk-in appointments to strictly scheduled visits.

The 615 new cases reported Monday morning represent an increase over Sunday’s total when the province reported 566 new cases of the disease.

Five more deaths related to COVID-19 were recorded over the last 24-hour period as well as 541 more infections the province now considers to be resolved.

Monday's report brings the province’s COVID-19 case total to 54,814 -- including 2,980 deaths and 46,360 recoveries -- a 1.1 per cent increase over Sunday's total.

Right now, there are 5,474 activce cases of COVID-19 in the province. 

The new cases were reported as walk-ins at the province's 153 COVID-19 assessment centres were discontinued to make way for scheduled appointments.

Premier Doug Ford called the change in strategy "absolutely necessary" following weeks of long lines and a growing testing backlog.
