TORONTO Winter weather in Ontario disrupted the students anticipated return to in-class learning in some COVID-19 hot spots Tuesday, as the education minister reassured parents that new safety measures were sufficient to controlling COVID-19 spread in schools. Schools boards in Peel and York regions closed schools and cancelled bus services due to heavy snowfall, though classes continued virtually. In Toronto, classes were held in-person in Catholic and public school boards, though no transportation was provided. In-person lessons were slated to restart in those three regions after a stretch of online learning that began in January as part of a provincial lockdown, which along with a stay-at-home order helped bring the number of new COVID-19 cases to below 1,000 per day.
