I believe the change that Lastpointe referred to is in regard to Sheltered Workshops closing subsequent to the change in Ontario minimum wage legislation. These are usually run by not-for-profit organizations - such as Community Living - to provide structure, social opportunities, respite for parents/caregivers. They are staffed by workers who teach & supervise the workers/clients who are not able to obtain competitive market jobs due to the impact of their disabilities. These are 'social service' agencies in that respect, not free market employers. No employers are getting 'welfare money' that I know of. So this differs from programmes that support those who can work in the general job market.
My prior employer, a public hospital, employed a handful of employees who have intellectual disabilities - they were initially trained & supported by staff from the local Community Living agency. I don't know what wage was paid to them - but they worked usual hours, rec'd benefits, etc.
