$585 per week but it passes through the employer's hands, who has to promise to top that up so that the employee is receiving at least 80% of normal wages.
But of course some employers won't be able to afford that (e.g. because their business isn't operating at all during the shut down), and some people are going to lose their jobs entirely. So apart from the unempoyment benefit (which would be far less than the $585), the govt. is considering other options like a universal basic income.
