Inland applicants get their CSQs faster than outlands with Quebec's PEQ program.
They are already prioritized.
(For ex. I applied for CSQ in Oct 2014 and got it in Nov 2018 - It took 49 months for me.)
Also, all additional points such as integration, French language, Quebec educational history, etc. give extra points to inland applicants in the CSQ stage. This is already a huge advantage.
But...
In federal processing, there are no checks for integration concerns, language, or education because these are already done in the CSQ phase by MIDI. PR processing in IRCC is normally straightforward and equal for all applicants regardless of their physical location.
So; the application should be processed in FIFO format or chronological order.
It is totally normal that an applicant who is applied 1 year before others should get his DM first.
And for we are paying our "taxes" argument;
People are paying taxes and they are getting benefits of all municipal and governmental services while they are living in Canada.
This is the cost of living and something people benefit from hospitals to post offices, subway lines to thrash collection.
Paying taxes does not make someone privileged at all, it is something everybody has to do.
