[Burney]

I guess people might reasonably argue it's a de facto ban on Muslims from those countries listed.

Anyway, it was Obama's list of countries. Trump has merely taken the list Obama's administration compiled to tighten up visa control and applied a more hard line approach. As he said he would while campaigning during the election he went on to win.

Meanwhile, we await with interest to hear of the nationality/ethnicity of the Quebec shooter(s).
