TORONTO — For the third time in seven days, Canada has broken its daily record for reported COVID-19 cases as provinces unveil new lockdown measures and officials urge Canadians to take the pandemic seriously. Canada reported 4,981 new cases of COVID-19 on Thursday, making it the worst day for new infections since the dawn of the crisis. Nearly a third of those infections were from Ontario, which reported its own daily record of 1,575 new cases and 18 deaths. New modelling suggests that Ontario could soon see up to 6,500 new COVID-19 cases per day by mid-December. If numbers continue to rise, Ontario Premier Doug Ford said he “will not hesitate” to roll out stricter measures.
