Unless there is a wave of outbreaks that can be linked to multiple restaurants in a particular market, they should not penalize that industry again. None of the data that I have seen is pointing to it. Outbreaks from private gatherings (i.e weddings, Thanksgiving dinners, hospitals, the Calgary Correction Center) spike the total numbers but it does not point to a widespread problem everywhere.
As long as restaurant owners are following protocols and policing guests accordingly, why can't they stay open?
The problem is that most cases are
currently from "unknown" sources. Over the past week, more than half of the new cases were from unknown sources. If you exclude the close contact cases to look at just where someone brought covid into a household, then more than three quarters are from unknown sources.
And because of the nature of outbreaks, we know that this unknown transmission is likely not coming from the same places as outbreaks -- there's nobody with covid sitting in a cell in the Correctional Centre (or a bed in a hospital), being recorded as an unknown source; we know where those cases came from.
It's unfortunate that the province hasn't been able to set up a good system to track (which takes humans, money and trust, not an app), but with most cases coming from unknown sources at this point, I don't think we can pretend they don't exist, at least not if we want to stop covid.
There is evidence that restaurants, bars and coffee shops are high risk businesses;
this study looks at 10 different activities, and restaurants, bars and coffee shops seem to be the highest risk businesses. Gyms and religious gatherings added risk although the sample wasn't large enough for statistical reliability; salons, offices, shopping, public transport and in-home gatherings had no additional risk. (Honestly, we should have this sort of information locally by now.)
I suspect the reason Kenney likes to talk so much about individuals having parties is because the more the spread can be blamed on individuals, the less it is a systemic problem, and he's in charge of the system. If he actually thought that parties were the problem, then in-home gatherings of 15 to 50 people (also known as... "a party") shouldn't be permitted.
