Ack, I don't know. As far as I'm concerned Harper was essentially evil, and if you were to drop him into the current American climate he'd fit right in. I mean, he was leader of the Conservatives when they proposed a "barbaric cultural practices" hotline. That alongside Bill-C51, the robocalling scandal, prorogation of parliament, destruction of scientific evidence & cuts to scientific research—I could go on and on. He also set the stage for Trudeau's current evasion of responsibility by pioneering the culture of the total non-answer in the House of Commons...
Re. Canadian schools—you would still be eligible for a SSHRC grant, no? As far as I'm aware citizenship or permanent residency is enough for eligibility, and there is pretty significant $$$ at stake. I suppose at this point in time it's not really all that useful, but when postdocs are in question it could be. Your Canadian citizenship will also give you a leg-up when it comes to Canadian jobs, eh.
