The COVID-19 pandemic

[tomh009]

Self isolation for those arriving from abroad has now been in place for a couple of weeks.  Whether something "should have" been done differently, sooner, whatever, is irrelevant at the moment, as the entire focus needs to be on fighting the spread of the virus now.  One can come back for "lessons learned" in future, when the war has been won.
Once reliable speedy testing becomes available, I could see it being used to address the issue of truckers and other still allowed to cross the border.

To me it feels like we didn’t really take it seriously until it was here. We didn't implement major changes in procedure until there were enough cases in Canada that a widespread cessation of in-person activities was needed.

And yet, travel from China was not the biggest problem. Ontario has had only five cases traced back to travel in China, seven for Italy and 18 for Iran, the three early hotspots. On the other hand there have been 64 cases from Mexico, 111 from the UK -- and 369 from the US.
