Since I have some time, I'd like to submit a few additional thoughts on your topic. I hope these can help you make your decision.
As we know, to find a job has three basic elements:
(1) Identify the location -- the positions or the jobs: where is your targeted job market?
(2) Sell yourself: to catch your potential employer's attention and to prove that you have all the capacities, knowledge and the will to do a good job.
(3) Position yourself: to prove that you fit your potential emploer's need (an excellent and reliable team player, an expert in a subject matter of your potential employer, etc.)
In these basic elements, you may analyze yourself and your targeted job market (including your targeted employers) to see whether there is a gap between what you have and what your targeted employer needs. If there is a gap, you may need to do something to fill the gap, either by going to a school or by doing a voluntary work. If there is no gap, the only thing matters in your job serching will be the time. Giving enough time of hard working in job searching, you will surely land on a nice research job in Ottawa to make changes to improve our living conditions and environment.
