The goal of guaranteed minimum income is to eventually replace all those other supports.  There wouldn't be welfare.  There wouldn't be OAS. There's wouldn't be CPP.  There wouldn't be EI.  There wouldn't be income for the mentally ill or disabled.  All those programs, with all that administration, get replaced with a "got a SIN? Get some money!" solution.  The idea is that getting rid of the rules and duplication gets rid of huge costs, and makes this all viable.

We're already paying it out, we're just paying it out in egregiously inefficient methods.

But, ON clearly doesn't get the concept.  Their implementation is like double welfare, as you said.
