What does Proroguing Parliament mean?

You've probably heard of Parliament being prorogued but what does prorogation actually mean? Who decides when to prorogue Parliament and why?

It’s pronounced “pro-rogue-ing” (yup, like Rogue One). When Parliament is prorogued, it means that the Governor General ends a session of Parliament. Prorogation typically happens at least once between elections. It allows the Government to reset its priorities and set a new agenda by opening a new session with a Throne Speech, and introducing a new set of bills for deliberation in the House. Four years is a long time in politics. Ideas that may have seemed great during an election may be less so now. Meanwhile, new priorities have moved to the forefront. So prorogation is a useful way to reboot the government’s agenda.
