Disability advocates have long said it should be the poverty line plus 15% to 30%. It costs more to get by when you are disabled, even at that very minimal level of the poverty line.
There's an easy way to look at it. Across the country, folks are generally receiving about $1,300 or so on disability. The poverty line is $2,300, so there's a $1,000 difference to get up to the poverty line. Here is a rule of thumb for the million individuals who would qualify for this: Every billion dollars invested equals about $100 for a person on disability. Therefore, you're looking at a program of $10 billion to $12 billion to get somebody from $1,300 to $2,300 as a minimum floor for a fully funded Canada disability benefit.
