Instantly pay everyone in Canada $3000 each and make them all stay home for 3 weeks... total shutdown/quarantine.
Pandemic is over as that's plenty of money for essentials... ie food/utilities/rent etc... and the virus won't be able to spread after 3 weeks of total containment.
Massive payout of ~$114 billion but they'll end up spending that anyway (and likely much more) and it will take many weeks to get the currently planned payment streams into people's/businesses hands with all the red tape they have to go through currently.
Yes it's a little simplistic (homeless and other special cases etc)... but the idea should always have been to very quickly get enough money in everyone's hands to buy food/drugs/necessities and do a proper and complete lockdown instead of this long drawn out process which is going to likely take many months to eradicate the virus.
