There were curfews all over Quebec, and Quebec's Jan 1. policies had the most precipitous drop in cases in any province in Canada at any time except the 'shelter in place' orders.

Your '1 and 2' points are not relevant speculation - and I don't care one bit about Legault or his government, it's besides the point.

The policies across Canada and most of Europe for that matter are not dramatically different.

Why are you only comparing to the rest of Canada? The drop also happened in the US. And in Europe. Also why aren't the curfews working anymore?

Also, I'm not sure how attributing any benefit to completely unproven NPI that the government literally admitted to putting in place because it "sounded good and it sent message" rather than based on any scientific data isn't the actual speculation here.

You're batching together policies to make the curfew look good by proxy.

All analysis that isolates the curfew as a singular NPI show no discernible advantage, and the government admitted to having no evidence it's useful at all.
