Given that EI regulations vary by region, it would have to be done at a very detailed level. One thing I'd also caution you about, concerning the increase in temporary and term and contract work, is that some of it is institutional change in the labour market. There's no doubt that there are people who hire more from temporary agencies, for example. Some employers want more contract work. Remember too, some of the increase in term or contract work is in construction. Something like 40% of construction workers are classified as temporary, because they're working on a job that has a specific ending to it.
People assume temporary jobs are sometimes bad-quality jobs, whereas most manufacturing jobs are permanent. If I were a construction worker in Alberta today, I'd feel a lot more secure about my job than a manufacturing worker in Ontario. I just don't think you can say that temporary is bad and permanent is good.
