You are weakening your own case by grandstanding. No sane person would expect you to "take responsibility" for some politician you didn't like (or help) to get elected in Ontario (a place with 14 Million people, but of limited global impact). You staying in Ontario (even without engaging in political activism) is not at all comparable to directly working on products you consider immoral in a company with an engineering workforce roughly one thousands the size of that but vastly bigger global impact. Neither in terms of personal culpability, sacrifices required or plausible positive effect your decisions might have.
