You're asking a lot. I'll try to get this in in as short a time as possible.
One of the things we have learned from CERB is that governments can respond quickly. When governments need to, they can respond quickly.
What we have also learned through the CERB is that people have fallen through the cracks. The reason they have fallen through the cracks is that the CERB was based on a traditional employment insurance system, and that system was based on a very old-fashioned, 19th-century definition of work. Work is wage labour. The EI system had to put so many bandages on that to start dealing with gig labour and precarious labour, so what the CERB and COVID have indicated is something many people have known for a long time, that the current system of EI and income supports is broken.
The EI system needs to be simplified. It needs some other type of income support to work with it in order to take care of people who do not fall into any of the traditional categories that an EI would fulfill.
