The path from Permanent Resident to Citizen in Canada is pretty straightforward in my eyes and most Permanent Residents eventually do become Citizens [0]. Given that there are many pathways available for people to immigrate to Canada and Canada also looking to increase immigration in the coming years I am not sure what you mean by "not friendly or welcoming". Are you referring to the fact that there is a selection process in place and not everyone may qualify due to it?
