Absolutely. The problem is that public policy in Canada was to get rid of more effective testing. PCR testing went away quite quickly, likely because it was very expensive. And so early on they deprived the public of the ability to diagnose and know whether they really had COVID before it was highly symptomatic (and spreading) but at the same left in place measures asking us to isolate etc. The issue with COVID all along vs other respiratory viruses is that it had the potential to transmit before symptoms appear. Which made things like temperature checks, etc fairly useless at preventing its spread. So actually it was important to know in advance if you had it, at least before mass vaccination and omicron changed the profile of the way it spread it seems. Schizophrenic public policy. Also by last spring the only way to know what was happening with the virus' spread was to look at wastewater detection numbers.
