Most of this is guesswork. Please provide evidence to back up any of these claims.
> 2) “Trust in government” is something that is thrown around but mostly it is speculation. It was said that Sweden didn't need mandatory lockdowns because Swedes trust in the government but people in the UK do not. And yet, with vaccinations both countries have done well without vaccine mandates. Is Canada really so much different from the UK? I really doubt it. It is probably more similar to the UK than to the USA.
Again, portions of the UK did have vaccine mandates, just not the most populous part. "Done well" is also a difficult pill to swallow given that the UK as a whole saw COVID-19 death rates of 2,359/1M people, Sweden had rates of 1,666/1M people, while Canada has had a rate of 948/1M people. The UK and Sweden also both lag behind Canada in terms of vaccination, at 85%/81% in Canada vs 77%/72% the UK and 77%/75% for Sweden,[2] despite the UK starting their vaccination efforts before every other country.
> My original argument was that vaccination uptake by elderly is that matters the most. And data clearly shows that it is true. For example, Israel despite strict vaccine mandates have poor vaccination uptake by elderly. It could be even argued that vaccine mandates may decrease vaccination uptake by elderly. As you say, Canada introduced vaccine mandates when majority of elderly where already vaccinated so that there was no noticiable slowdown in this group but other countries may have even made this worse by pointless vaccine mandates.
I'm not sure how making proof of vaccination a requirement to do things is going to prevent people from getting vaccinated. Also, you appear to be completely wrong about Israel, as according to [3] the 60+ crowd are driving the bulk of their vaccinations at 80% with two doses.
If you're going to continue to debate this, please at least research the things you're going to respond with.
