We do have this new report that just came out today called “Underemployment is Canada's Real Labour Market Challenge”. Angella is one of the authors of the paper. Basically it breaks down to underemployment, that 27.7% number, is considered to be: those who are unemployed, so unemployed young workers; those who have dropped out of the labour force and aren't looking, that's those 350,000 young workers who are no longer looking for jobs or who have returned to school; and those who are involuntarily working part time.
One of the numbers we get through Stats Canada is they do an averaging of the number of hours part-time workers are looking for, and don't talk about the actual number of workers affected, so that's how we get to that number.
