Well, it wasn't hidden that parents are not considered as part of the immediate family unit on IRCC website.
As you immigrated, it's the fact that you may be living in a different country than your parents. Good luck on the future lottery if that's the on-going process with IRCC for PGP. (they could stop PGP entirely which they did before)
Yes, naturally when you immigrate you cant bring your immediate family members next year but why not after 10 years if I have paid taxes and never been unemployed? Why cant I have my parents live in the same country before they die?? Why not? Taxes I pay take care of elderly parents of Canadian Born citizens, and elderly parents of Immigrants who came here 20+ years ago. How come my taxes cant even bring my own parents in the same country I live?
