Please see this site:Thank you. I do have a Ph.D (Public health Dentistry) from the University of Adelaide, Australia and Degrees from Ireland and UK Royal College of Surgeons, Over 50 publications in high impact factor journals but no grants. Its not easy to get grants from outside Canada unless one is employed in Canada and can look for collaborations. I have been looking for opportunities since quite some time despite the personal issues I have at the moment. But there are hardly any in the 10 universities in Canada and mostly people who have pursued a higher degree in Canada are employed by their supervisors. This has been the experience. In many of the positions academia the interviewers know whom they are looking for.

Are you accredited as a dentist in any of Australia, NZ, UK, USA or Ireland? This says that if you 'qualified' in those countries, Canada will recognize.
Because it seems to me you are overthinking this: if you can be licensed here, you work as a dentist to pay the bills, and pursue other opportunities in parallel as you build a network here. I'm assuming your experience is not just as an academic.
If you can't figure this out on your own, I suspect there are specialized placement agencies that can help. My understanding is a lot of practices need extra competent hands.
As far as the academic side, I have only peripheral exposure to it - but my understanding (more from the medical side) is that while a full-time position is not that common, the big schools and teaching hospitals work with a lot of doctors on non full-time basis. Perhaps those later can develop into more serious, I don't know.
Hope this helps, I repeat, I'm not an expert, but you have to get on this if you want to proceed to move. If you already know all this and I've msised the obvious, ignore of course.
Good luck.
