Sunnybrook Health Sciences Centre will construct a mobile field hospital in a nearby parking lot as it prepares to deal with a possible third wave of the COVID-19 pandemic. It will be a giant, reinforced tent. A similar structure was built at Joseph Brant Hospital in Burlington but it has seen little use. In mid-Janury, at the height of the second wave, it had 14 patients and 73 empty beds. Nonetheless, governments are taking a cautious approach to the idea of a third wave of infection. Some have suggested that the tent hospitals might be used as vaccination centers.
