A lot is being made of the reduction in testing in Ontario. I tend to agree - if there is capacity we should take advantage of it. More information can only help.

That said, can the decrease in testing tell us anything useful?
Rationing is done on criteria. If you fulfill the criteria, you get a test. If the criteria was consistent, fewer tests means fewer people met the criteria. Here's what's listed on the health ministries site for the criteria applied since the 27th:

So, which of these groups of people can be reasonably presumed to be decreasing in numbers? That's what I'll use this thread to discuss.
"Symptomatic health care workers (regardless of care delivery setting) and staff who work in health care facilities"

Hospitalizations due to COVID-19 (reported since April 1) is increasing. It's unlikely that this group of people is decreasing.
"Symptomatic residents and staff in Long Term Care facilities and retirement homes and other institutional settings eg. Homeless shelter"

I don't think this is decreasing either. There have been many reports of long term care facilities having outbreaks
"Hospitalized patients admitted with respiratory symptoms (new or exacerbated)"

This more directly relates to hospitalizations discussed earlier in the thread - also probably not decreasing.
"Symptomatic members of remote, isolated, rural and/or indigenous communities"

Haven't seen many reports, but it's possible this has decreased, but I think it's unlikely.
"Symptomatic travellers identified at a point of entry to Canada"

And here's the crux of it. I think we're seeing a decrease in testing because we've now processed the returning travelers from March break. They should now loosen rationing criteria now that that is over.
It's also interesting to look at this think about the resources spent on March break travelers. Some are talking about how March break timing might have had a large affect on preparedness - comparing BC and other provinces for example. This I think supports that notion.
