"Prorogation" is the term we use to describe the end of any session of parliament in Canada.
Or as the Canadian Parliament web site says, "Each session of a Parliament ends with the prorogation of Parliament by the Governor General, on the advice of the Prime Minister."
Since Canada's confederation in 1867 (143 years ago), parliament has prorogued 105 times. That's an average of about 1.4 years per session (some are longer, some are shorter).
Use of the term "despotic" in this context makes you automatically a lunatic.
That is all.
