The phrase "rente du Quebec" loosely translates into "Quebec pension." This is a portion of a phrase, "Régie des rente du Quebec," which is the national pension plan for the Quebec territory in Canada.
The territory of Quebec has its own pension plan, as it did not want to affiliate with the Canadian pension plan. Both plans feature similar benefits, and it is compulsory for all Canadians who are working and earn over $3,500 annually to participate in the pension plan, as of 2015.
The purpose of the Quebec Pension Plan is to provide all Canadian citizens with financial safety net in case accident or injury makes it impossible for a citizen to earn income.
