Why don't you apply to some universities as a Professor or maybe even a High school teacher? Find some recruiters who cater to jobs in your field of study on LinkedIn and ask them to get you on an interview. I don't understand why you are applying for survival jobs when you have a PhD.
Do you have US experience? I'm asking because couple of my friends and my distant cousin + his wife, went to Canada, with US experience and all of them were able to secure a full time job within 3-5 months of landing in Canada. They said as long as you can speak English fluently, have valid experience that you can demonstrate during the interview, you should be able to secure a job without any trouble.
