First, it was an emergency. They shut schools and the border was closed. But not at Pearson (and we went on March break.) They closed parks for the cherry blossoms. We lined up outside grocery stores. Then it was Stage 1, 2 and 3. Then it was “modified stage 2”.
We were told not to dine indoors — but you still could. They said "everyone can get tested," then it was only a few of us. Then appointments only. We all had our bubbles. Then there was colour coding. Then they changed the colours. And grey was worse than red.
Then there was “grey +” which was also a “lockdown” (but for most of us only after Boxing Day). The border was still closed, but you could fly to Cancun. Still can. Our kids went to school during the lockdown, then they didn’t. They will again soon. Probably.
Now: A stay-at-home order; only leave for essential reasons or you get a ticket — maybe — but non-essential retail is open. Work from home or else go to work, whichever. No cottage, unless it's essential. Use your judgment.
We're done with stages. The bubbles aren’t a thing anymore. The colours are... still.... a thing?
I think.

2/n The problem is that all the ups and downs in these lines strongly suggest *narrative* — but for the most part, the data doesn't have anywhere near that fidelity.
Big turnarounds happen in pandemics, yes, but you won't know for sure you've had one until weeks later.
3/n Think of all the times we've heard about flattening, or a plateau, or a spike after some holiday.
You can see those moments clearly in the ups and downs of the fall wave.
At the same time: You can also draw a remarkably straight line through the same curve.
1/n Not long after I did the attached chart of cases by age, I realized I could use the Ontario database to predict how deadly each day's set of new cases might be, based on the age breakdown and their average death rates.
The labs first need to *have* samples to be able to test them, so the fact more tests were collected than tested yesterday does not yet suggest there's a "backlog" problem.
With big input numbers, it's normal for a large total of tests to be in the queue at the end of the day.
The question is whether the labs can handle this input after it comes in, so should watch to see if the completed number gets back up into the mid-to-high 40k range tomorrow.
