1. Canada isn't focused on quickly growing its population; it has housing, unemployment, and healthcare issues. The government follows a yearly immigration plan.Still all other pr applications process within a year time frame just saying we should have the same processing time
2 . Government gives time for protected people to adjust, adapt and start paying taxes. This is because many people who get citizenship leave soon after, and most apply for asylum just for economic reasons. That's why Canada doesn’t offer fast citizenship or PR.
