The good news is that there is no age limit! Whether you are 18 or 80, you can apply for Canada PR.
Of course, there are some requirements you will need to meet in order to be eligible. For example, you will need to have a valid passport, meet the language requirements, and have a job offer from a Canadian employer.
If you meet all of the requirements, then you can apply for Canada PR. The process can take a few months, but it is well worth it if you want to live in this beautiful country.
There is no age restriction on any Canadian immigration program. However, in most economic immigration categories managed by the Express Entry system, candidates aged 25-35 get the most points. Older applications are not excluded from being considered. You can easily receive an ITA to apply for a Canadian PR visa even if you are over 40 years old, as long as you meet the minimal requirements for all selection factors.
