I think you missed my point, increase of fees is not to make it less affordable and limit the application amount, but for government to use the additional money to bring more resources to clear the applications. It also creates more jobs while serving immigrants better, I think it's win-win.
Also if affordability issue is a concern, they can create different service levels, so immigrants can choose according to their affordability. Such as in Britain, there are three service levels for immigration applications. 1. Normal Postal application. 2. Same day in person application. 3. VIP on site service, yes! officers come to your place if you are rich enough.
Again, it's Canada, everything is slow and not efficient, I can only dream it.
