A three-week lockdown in certain regions of the province is necessary to blunt the explosive growth of the variants of concern, Ontario’s COVID-19 scientific advisory table says. Dr. Peter Juni, the scientific director of the advisory table, believes Ontario could see between 2,500 to 5,000 new cases of COVID-19 per day in a few weeks, if the current trends continue. Ontario recorded more than 1,500 cases on Wednesday, the highest single-day total since early February, owing in large part to the variants of concern which account for more than half of the new cases. “What we’re talking about here predominantly is the Golden Horseshoe, the Golden Horseshoe has a major problem, and we need to tackle this,” Juni told CTV News Toronto. Cases from Toronto to Niagara Falls have been steadily increasing over the past few days triggering alarm among health experts and health-care advocates who have warned that the rise in transmission rates will lead to the third wave.
