Personal opinion, but I think most people are applying or landing in Canada without jobs. Exceptions are, of course, most of the inland applicants who are already in Canada and those people who received job offers to apply for PR. However, most start applying before they get to Canada and from what I have read and researched, it is close to impossible to get a job in Canada without living in the country. Also, financially, be prepared to spend at least 3 months searching for the right job. You can, of course, get retail or workshop or wearhouse jobs in the meantime to pay the bills, if you are so inclined. Here's a link to the discussion board that will help you get started:
