We're hearing more and more noise from premiers about international travel, but are there actual cases of outbreaks linked to someone breaking the quarantine and running around in public?
I don't see how spring break can be that much of a threat this year. Just by looking at flight schedules, there are few direct flights going south. A small number to Florida, 3x/week to LAX, some Cancun, a few islands. The U.S. carriers have very limited frequencies to hub airports, making connections quite difficult. Most of the sun routes AC/WS offer end up getting cancelled in the weeks leading up to the flights. I know for a fact that teachers have been instructed by school boards not to travel while the quarantine rule is in effect, so that rules out a significant number of would-be March break travellers.
They can force incoming travellers to stay in hotels and quarantine camps all they like, but it's not going to address the real issue - shared househoulds with people working in high risk environments (food processing warehouses, nursing homes, Amazon/Canada Post warehouses, factories). It's as if they want to scapegoat the odd vacationer because doing anything to target the actual problem would suddenly make life inconvenient for those in lockdown and working from home.
