Here are some of the things I've written about the UBI/"cut 'em a cheque" approach.
1998: The Growing Gap, pp. 101-104 https://www.policyalternatives.ca/publications/reports/growing-gap-report
2016: Basic incomes vs basic services https://www.thestar.com/opinion/commentary/2016/07/19/basic-income-how-about-basic-services.html
2017: Redistribution through a basic income https://www.policyalternatives.ca/publications/monitor/redistribution-through-basic-income

I also recently wrote a note, on request, re emergency response $2K for erryone version, but didn't prep it for a public opinion piece because, frankly, that horse has left the barn, and there are still policy fixes in evolution that *can* be shaped. But time is in short supply.

Like @JenniferRobson8 and I wrote here in mid March, the list of policies to keep people afloat during Covid19 is short, related to:
1. Incomes
2. Debt/pausing payments
3. Housing/shelter costs
4. Vital social infrastructure (nonprofits/volun sector) https://www.thestar.com/opinion/contributors/2020/03/13/how-to-help-workers-and-the-economy-during-the-covid-19-crisis.html

When the medically induced economic coma ends, and we start regaining use of our economic anatomy, we will need to keep some vital supports in place: housing and social infrastructure (child care, food and shelter, help for those experiencing domestic violence, mental health)

We don't know if we will suffer relapse.
We won't know if less flow in parts of our shared economic anatomy will result in permanent loss.
Covid19 is blitzkrieging the economy, and we won't know what's left to rebuild on until it's all over.
The other side better be different.
