The Blue Jays had permission from the city, the province, but ultimately not the Canadian national government. The reasoning is, of course, not wanting to introduce more COVID-19 cases by relaxing travel rules for people coming from the USA.
Now they have to decide where to play. Their spring training camp, in Dunedin, FL, would be perfect…except my home state of Florida is one of the hardest hit by the virus. Their AAA location in Buffalo might be a possibility. The Jays have said they would have to upgrade some practice facilities/equipment and be creative with locker room arrangements, like converting some suites, to be able to maintain social distancing. They might have to resort to a plan D.
They open in Tampa, and their first home game is game 5…so they have a little over a week to get the situation resolved.
