Just want to get something clarified, does flag poling mean you are already in Canada, but you just want to cross the border to US side and then come back to Canada?
Am I correct in understanding that if you are in US on a visa and want to land in Canada, and come back to the US it is not the same thing?
Flagpoling just means you are already in Canada and you cross to the US but then tell US CBP you want to flagpole.
They then issue an admin refusal piece of paper and you then return to the Canadian side where you tell them you want to activate whatever visa or permit you want to activate so not quite the same as being in the US as never actually physically enter the US. Do not even need a visa to enter the US when flagpoling.
Of course there is always the possibility that if someones documentation is not in order they could in theory be inadmissable back into Canada
A couple things with this thread 1) cannot find anything official just the PWC link 2)does this also apply to people who start out from within the US, then cross to Canada , so they are not in effect flagpoling but simply landing as they might do at an airport POE. Will those applicants also get refused as though they were flagpoling even though they are not, looks like they might be as well.
As said nobody seems to be able to point to an official CBSA announcement so people will either need to take a chance or rely on feedback from people who took the chance.
