It all depends on individuals' situations, but it is certain that coming to the country with a temporary status and waiting a long time for permanent residence is difficult for everyone. Everyone must make a living, be quickly integrated and have the assurance that they will remain safe. I think it is important to finalize files as quickly as possible. The more quickly permanent residence is granted, the more quickly people can know they can be safe with their family.
This could also avoid the doubling of the number of procedures such as applications for visas, TRPs or permanent residence. The quicker the residence confirmation and the more those people can work and contribute to society, the better it is for Canada.
