In practice, Canada is a parliamentary democracy, but constitutionally it is actually a constitutional monarchy. The ''head of state'' is in fact the Queen of England, Elizabeth II. The Queen of England though has this ''power'' only as symbolic one, being remnant of the history of this country. In practice, the Queen of England has no real power in Canada whatsoever, as it is the case in her homeland, the United Kingdom.
