No -- I mean, I'm not an adcom or anything, but fromwhat you describe, you are interviewing for the WL, not for an A at this time. It sounds like they like you enough to want to meet you, but they are not going to extend an A to you unless or until spots open up after other people they have admitted turn them down much later in the process. It's not necessarily an uphill climb, because they do accept people off the WL every year, and you would be interviewing for the "priority" WL as opposed to the regular one, but still.
MSAR says they accept Canadians "case by case," the same as OOS, DACA and other foreign. TBH, anyone here who does not work with UWV admissions, including me, would just be making an educated guess. I've never actually heard of an II for the priority WL this early in the cycle. If I were you, I'd call them and ask. Good luck!!
