The Omicron variant of COVID-19 appears to be less severe than previous variants. But it's wildly contagious, so many more people are getting it, meaning hospitalizations are going up. It was in this context on Monday that Ontario Premier Doug Ford announced a series of new measures, including shutting down indoor dining, cinemas and gyms. Social gatherings will be limited to five people indoors and 10 outside. Ontario schools are also moving online until at least Jan. 17. Quebec had already announced a similar measure.
