Industry professional how-to PhD, Canadian or other?

Hi AskAcademia,

I've checked out various pages for guidance, but coming up short. I hope I can find some insight under this community. My apologies in advance for obscurity or limited information, as I must consider certain identifying factors.

I'll try get to the point. I'm in my thirties, at the lower echelon of senior management in a locally prestigious organisation, in a rather niche and specialised field (locally, less so abroad), and commanding a considerable salary locally. I followed an unconventional route in my career, but it has landed me some professional STEM practice licenses locally and in the UK. I also have a considerable number of qualifications, of which the major ones at master's level would fall under the construction/information industry, and business/accounting/finance, both first class.

Nonetheless, because of reasons and at full intent of uprooting life, I would like to pursue a PhD as an international student, ideally in Canada - I have strong topic preferences, but from my outreach so far, it seems one only get in via funding, and funding seems to mean "if you can and will do what I need, you can at least try to compete for entry". Honestly, at this stage I'm content with doing that.

I've reached out to several supervisors I've identified as aligned, under the Mechanical and Industrial Engineering Faculties at UBC, UofT and TMU in Canada. So far, it doesn't feel to be going well. UBC's supervisor had no vacancies, UofT has been nonresponsive, and TMU has responded and awaiting further. It also seems access is impossible even if I was self-funded, which was a surprise, but I understand capacity constraints and external funding is more profitable. At this point, I'm considering I need to reach out to every uni in Canada, and also foot the bill and apply at every uni in Canada once Winter 2027 admissions open (I seemed to have missed Fall 2026).

Does anyone have light to shed, or guidance to provide, in my attempt to get into a Canadian university to study PhD in MIE? Heck, I'm even open to alternative routes thanks to my comprehensive qualifications, if my preferences are impossible to satisfy.
