I have a similar question. my friend had applied for their immigration 10 years back with her family and upon arrival they applied for their PR and health card. stayed there for a a few weeks but unfortunately due to some emergency they had to return back to their country. Now the problem is they want to visit canada but when they apply for a visa it gets denied. so the question is weather they can enter canada on their landing paper through the border considering they never recieved or collected their PR card to begin with?
