Less than half of working-age Canadians with physical and mental difficulties have a job, a significantly lower percentage  than the general population, according to Statistics Canada. A data agency report released Wednesday that covers data from 2011 indicates 49 per cent of Canadians between ages 25 and 64 who said they have a disability could find employment. That compares with a 79 per cent employment rate among the general working-age population. The more severe the disability, the less likely an individual with get work. Employment rates for university graduates with mild, moderate and severe disabilities weren't that far off from the rate for those without any disability — the rates for all the categories ranged between 77 and 83 per cent.
