You need to understand the context of the phrase.

"I'm entitled to my entitlements." was statement by former Liberal Cabinet Minister David Dingwall who was forced out of his position as head of the Royal Mint by his political enemy PM Paul Martin. (Dingwall was Chretien loyalist).

Two  independent reports (one by Price Water House Cooper and the other by the law firm of Osler, Hoskin and Harcourt)  completely exonerated Dingwall and retired Superior Court Justice George Adams found that the Government of Canada essentially forced Dingwall out when he released his findings in a binding arbitration ruling.  In law it is known as constructive dismissal so there was nothing voluntary in his resignation.

So Dingwall was in fact entitled to his entitlements -  a severance package set out in his contract of employment.

BTW I am a long time Conservative (nigh on a half century) inspired by that great Conservative John Diefenbaker.
