The Dec 21-Dec 27 Canadian COVID Forecast and associated data are now live.

SEVERE: BC, NB, NL, PEI
VERY HIGH: CAN, ON, QC, SK
HIGH: AB, NS
ELEVATED: MB
MODERATE: North

Link: covid19resources.ca/datadiscussion…
The scores have become more volatile in the last week. We usually see this at start of new waves, when some provinces are still seeing some numbers coming down quite low compared to earlier periods, but there are starting to be spikes in other variables, especially waste water.
We're not sure if there will be a new wave, or if it will happen in all provinces. Some, like PEI and NS, were in a very prolonged very high period recently, so numerous reinfections may be less likely there. Maybe.
Some, like MB and the North are really coming down quite low compared to previous levels.

But...I'm worried this may not be for long, and there could be rapid change over the holidays.
Certainly, we're seeing the largest provinces with the most reliable numbers (because of their size) trending back up. That's ON and QC.
QC is the fastest reporting province and increases there are usually a warning sign for the rest of the country. If you've been watching our COVID Forecast for a while now, you also know that QC has stayed in the elevated-high range for quite a while until recently.
In reality, most provinces now have similar numbers of people infected, barring some late surges in BC, PEI and NS where infection numbers had been lower. There's a competing stew of variants out there, but they don't respect provincial borders.
If you see QC (and Atlantic Canada) going up, assume it's happening where you live too, or will soon.

This is especially important over the next few weeks, as data silence descends on most provinces and we won't have many numbers again until the 2nd week of January.
Back in a second. Just putting the coffee on and feeding the birds, and then I'll post the graphics for each province.
Sorry. Just realized the seeds are low and our horde of evening grosbeaks are out there querying the situation. Should have fed them first!
Also FYI we'll post one more updated forecast this Friday/Saturday that will run until Jan 3. We'll have a bit more data from PHAC then and more waste water data.
Given the volatility of the numbers in some provinces we want to be sure we're not under-forecasting anywhere, since people may use this info to make decisions about holiday gatherings.

Hi folks,

The Dec 21 Canadian COVID forecast and data are now live.

I'll do a full thread tomorrow when the team has our graphics ready to go.

But I wanted to get the overview out because some provinces are increasing, including QC, which usually warns rest of country.
I've had time to update more of the model and input data, so it might be worth checking out for the data folk.

We've also started hand-tallying the severe outcomes by age and date in the PHAC weekly epi report. It's not downloadable, so it's a lot of work.
When we're done, we'll post the numbers on a publicly accessible page so no one else has to do the hand tallying to use the data in their analyses. We'll try to update weekly or biweekly--it's REALLY time consuming to do. I'm not great at scraping data from web pages. Sigh.

Hey Ontario,

You know all those COVID deaths you haven't reported publicly?

You do know they eventually show up in the PHAC COVID dataset and in the CVS-D registry, don't you?

Now would be a good time to report them before your excess mortality for the last 6 months comes out.
It's a g*d*n pain in the ass to assemble all the reported numbers reported from multiple official sources, and they're inevitably out of date, but people like me keep doing this, and will keep doing this.
Data under-reporting will catch up to you. Transparency is essential for trust in public institutions. It's not me pointing out death counting discrepancies that causes loss of public trust. It's you not reporting transparently to begin with. YOU can choose to improve trust.

Still waiting for @StatCan_eng to post the last @GovCanHealth dataset of 2022. So some of the 2022 numbers will still increase.

But here are weekly reported COVID hospitalizations, ICU admissions, deaths, drug-adjusted excess (untimely) all-cause deaths for 2020, 2021 and 2022.
@StatCan_eng @GovCanHealth Since more than half of the country hasn't reported any deaths at all to the Canadian Vital Statistics registry for the last 6 months, 2022 excess mortality is based on fast-reporting provinces only (NL, QC, AB, BC), adjusted to Canadian population size.
@StatCan_eng @GovCanHealth The 2022 excess mortality numbers will still go up, even for the fast-reporting provinces. It currently appears that reporting is most complete in BC and NL, with big chunks of expected deaths in some age groups not yet reported overall.

Apologies for the delay. I had to get a new keyboard, then catchup on work deadlines d/t keyboard downtime, then the Friday night model updates morphed into the weekend b/c of technical problems. Grr.
Today, I'll share graphics developed by an incredible working group of (mainly non-scientist) contributors.

These have less detail but we hope will be easier for more people to understand quickly.

COVID infections and hospitalizations in Canada have declined in recent weeks.

BUT there are still more people hospitalized with COVID than at the height of any pre-2022 wave.

This number is collated from numbers reported on each provincial website. Some provinces only report new admissions (not total people hospitalized), which accounts for some discrepancy.
