U r wrong in this situation. I know so many guys who came on visit visa. Got lmia job. Went to the border and get there work permit and working in canada now. Not just one i know hundreds of them.You’d actually want to call the border you plan on attempting to flagpole at to see if you qualify to flagpole and whether they are accepting flagpolers and when/how many per day. Since I can remember there hasn’t been a situation where visitors from non-visa-exempt countries can get a WP via flagpoling. They only would qualify if they were previously in a WP or SP.
